Students Investigative ‘Crime Scene’ in Waikiki

The “crime scene” in Waikiki drew more than a few curious glances from beachgoers and passersby.

But it wasn’t police investigating the site. Instead, Chaminade University Forensic Sciences students—in official CSI gear—were the ones collecting evidence and documenting the scene.

The mock crime scene was set up in early April as a hands-on learning opportunity, allowing students to practice critical forensic skills.

“They feel the reality of being in an actual crime scene,” said Carlos Gutierrez, D.F.S., assistant professor of Forensic Science. “They’re applying all the skills they learned during the semester in a more specific and realistic scenario.”



Chaminade’s Forensic Sciences program is known for its practical approach, blending rigorous academics with real-world applications. The setup in Waikiki demonstrated Chaminade’s commitment to hands-on learning, giving students a chance to navigate complex investigative procedures under faculty supervision, Gutierrez said.

The major in Forensic Sciences includes instruction on the techniques used for recognizing, documenting and analyzing physical evidence, reviews of the legal system and ethical guidelines that govern forensic sciences, and hands-on applications of the scientific method in a lab.

All Forensics Sciences students are required to complete a rigorous, 135-hour internship. Students have completed internships with a variety of entities, including the Honolulu Department of the Medical Examiner, police departments in Hawaii and Guam, and the Joint POW/MIA Accounting Command’s Central Identification Laboratory.

Silversword STEM Camp in American Samoa

Chaminade’s I Am a Scientist program is all about hands-on learning

For the first time since its founding in 2009, Chaminade’s popular I Am a Scientist summer camp traveled thousands of miles away to American Samoa this year, setting up base at the Lyndon B. Johnson Tropical Medical Center in Fagaalu on the eastern shore of Pago Pago Harbor.

Rhea Jose, an outreach coordinator for Chaminade’s CIFAL Center, said the two-week health sciences boot camp was geared toward first to eighth graders. In all, 169 students from elementary to high school attended the camp, getting a taste for what scientists do every day. “We brought six large luggage, which were packed with all kinds of equipment, including microscopes, DNA extraction kits, pulse oximeters, blood pressure cuffs, pipettes, thermometers, black lights, even glitter,” Jose said.

Since its inception, the I Am A Scientist outreach program has reached 72,339 students and visited 450 schools across Hawaii, Guam, Saipan and now American Samoa, according to Lori Shimoda, I Am A Scientist founder and research associate in the Natural Sciences and Mathematics department.

Shimoda said before the program was launched, she had several discussions with CIFAL Honolulu Research Director Dr. Helen Turner about the need for a program that allowed keiki to experience what it means to be a scientist first-hand. “We were at a loss for how to do it,” Shimoda added, until her son—in third grade at the time—came home from school complaining that his science lessons were boring.

The reason? “They did not get to use the cool scientific equipment in the laboratory.”

The comment became the blueprint for the IAS program.

With the help of other faculty members and Silversword students, Shimoda started to take actual scientific equipment and supplies into classrooms to teach keiki about science by letting them become real scientists, using real scientific experiments and techniques.

“IAS takes real scientists and science undergraduates into the classroom so keiki can meet and talk to them about what it’s like to be a scientist, and how to go to school to become one,” Shimoda said.

“We offer a unique and fun science experience using equipment not typically found in schools. The science lessons are robust, and taught by working scientists.”

Funded by the Frederic Duclos Barstow Foundation for American Samoans, the IAS-AS camp was a unique collaboration between Chaminade and the Lyndon B. Johnson Tropical Medical Center, which ranks among the best medical facilities in the Pacific and is the only hospital in American Samoa.

Other partners included the American Samoa Telecommunication Authority, American Samoa Department of Youth and Women’s Affairs, the American Samoan Department of Education School Lunch Program, The National Science Foundation’s Alliance Supporting Pacific Indigenous Computing Excellence (ALL-SPICE) and CIFAL Honolulu. The camp focused on health science, a key need area.

“We remove barriers to participation by going to the school and being free,” wrote IAS-AS program staff member and Associate Professor of Biology Jolene Noelani Cogbill, in a write-up on the camp.

“We received daily comments from parents and community members, expressing their gratitude for bringing Science, Technology, Engineering and Mathematics to elementary-aged students to American Samoa, and asking if the IAS-AS program would be coming back regularly.”

They also noted how there are few educational STEM opportunities for students in American Samoa, and those that do exist are targeted towards high school students, Cogbill said in her report.

One of the modules focused on how easily germs spread and the importance of hygiene management. Campers were also asked to pick an environment (shoe, table, hands, etc) to swab and culture on agar plates so they could visualize “germs” on Day 3 of camp.
In this module students were introduced to the importance of OBSERVATION as a key part of not only the scientific process, but in our daily lives. They used their 5 senses as well as various scientific tools, such as magnifying glasses, digital and dissecting microscopes.

Environmental Science

After earning her bachelor’s, Casidhe Mahuka joins CRAG in American Samoa

In recent years, scientists, world leaders, politicians and environmentalists have been warning us about a dire existential threat, noting that climate change poses a grave risk that needs to be urgently addressed and mitigated. As an invasive species coordinator (ISC) at the Coral Reef Advisory Group (CRAG) in American Samoa, Casidhe Mahuka ’22 is doing her part in monitoring and protecting the waters encircling the small U.S. territory.

Since graduating with a BS in Environmental Sciences, the American Samoa native has used her Chaminade education to make an impact in her community. As the ISC for CRAG, Mahuka collects ocean data and implements bi-monthly phytoplankton monitoring in association with the National Oceanic and Atmospheric Administration’s National Phytoplankton Monitoring Network (PMN), which is a community-based network of volunteers who monitor marine phytoplankton and harmful algal blooms (HABs).

Mahuka explains that she has three overarching goals: 1) Integrate community-based methods to restore village-level ecosystems using ridge-to-reef approach in Aua and Fagasa; 2) increase invasive species management policy and activity coordination in and among local and regional organizations; and 3) bolster invasive species management in other priority sites.

“Other priorities include monitoring ballast water, biofouling, reef flats, and testing the water’s salinity, turbidity and overall quality,” Mahuka further describes. “I also work with the US Coast Guard to stay informed on stony coral tissue loss disease, the Vessel Incidental Discharge Act (VIDA) and other regional biosecurity issues.”

Covering more than 70 percent of our planet, the world’s oceans play a crucial role in regulating climate and supporting diverse ecosystems. However, the alarming rise in ocean temperatures due to climate change is threatening marine life, particularly the delicate balance of coral reefs.

Casidhe Mahuka prepares to tie an Anchor Bend knot.
In the summer of 2018, Casidhe Mahuka participated in the SEA Semester, which is Boston University’s Study Abroad Program. The ship traveled from Tahiti to the Hawaii islands.

Primarily driven by human activities such as the burning of fossil fuels and deforestation, climate change has led to a significant increase in global temperatures. As a result, the world’s oceans are also experiencing warming trends, the consequences of which are far-reaching and affect marine ecosystems in various ways.

“Our ecosystems are fragile,” Mahuka says. “Although they cover only a small fraction of the ocean floor, coral reefs support about 25 percent of all marine species. The intricate structures of reefs provide habitats and food for a vast array of marine life, including fish, invertebrates and microorganisms.”

Furthermore, coral reefs act as natural barriers that protect coastlines from the impacts of storms, hurricanes and erosion. The complex structures of coral reefs also dissipate wave energy, reducing the intensity of waves that reach the shore.

Mahuka has had a passion for ocean science ever since she visited the National Marine Sanctuary of American Samoa in the 7th grade. It was the first time that she discovered that she could not only breathe underwater, but she could also breathe underwater for a living.

“That was it; I was totally hooked,” Mahuka says. “I was determined to be an ocean scientist because I have always loved being in the water. And to get paid for it, I was all in.”

As a member of the first cohort of students who majored in Environmental Science at Chaminade, Mahuka mirrors a growing trend among students who are pursuing their degrees in this field, marking a 24 percent increase in degrees awarded since 2016. Data from the U.S. Department of Education shows a steady uptick over five years. In the 2017–2018 academic year—the most recent year for which aggregate data is available—a total of 6,697 students earned bachelor’s degrees in environmental science. That means 1,155 more graduates earned such degrees than did five years earlier.

The trend is illustrated by Chaminade’s School of Natural Science and Mathematics’s introduction of an Environmental Science major four years ago. While a major in Environmental Studies has existed since 2000, the decision to focus on hard sciences was a natural progression for such programs.

While there is an overlap that exists between the two majors, Environmental Science is an interdisciplinary science-based major, which combines biological, ecological, chemical, geological and mathematical principles often used to solve environmental challenges or manage natural resources. Conversely, Environmental Studies is an interdisciplinary social science and humanities-based major. It focuses on the human relationship with the environment, and how environmental challenges intersect with politics, economics, society and culture. 

For 10 days in November, Mahuka was aboard the Exploration Vessel Nautilus surveying previously unmapped seafloor in U.S. waters south of the Hawaiian Islands. She was selected as a Seafloor Mapping Intern by Ocean Exploration Trust (OET), an organization that works to explore the ocean, seeking out new discoveries, while pushing the boundaries of STEAM education (Science, Technology, Engineering, the Arts, and Math) and technological innovation.

“It was a great experience after I found my sea legs,” Mahuka says. “I definitely chose the right career because marine science allows you to travel around the world, where you get to meet and learn from amazing and intellectual people who have the exact same passion as you do!”

Medical School Journey

Rachel Arakawa enters her final year at George Washington

She’s more accustomed to dispensing medicine than she is advice. So, when asked what she would advise students to expect when they’re in medical school, Rachel Arakawa ’20 offered this simple suggestion: “Keep focus on your goals. And remember, you are just as qualified as anyone there.”

During a casual information session with students enrolled in Dr. Amber Noguchi’s HP 390 class–Advanced Topics in Health Professions Preparation—Arakawa shared her journey to George Washington University’s School of Medicine and Health Sciences. Like many freshmen who entered college amid a global pandemic in 2020, the former Silversword soccer and tennis player had to decide whether to stay home or move to Washington D.C.

“Even though all my courses were going to be online, I decided anyway to move to D.C.,” said Arakawa, who hopes to do her residency either in the Maryland–Virginia area or on the west coast. “That first year was really tough because it was my first time being away from home, and I had six to eight hours of online lectures every day, and then another two to three hours of reviewing the previous day’s content. We covered everything I learned as an undergraduate in two months.”

Chaminade President Dr. Lynn Babington welcomed Rachel Arakawa '20 back to campus this month for an informal discussion with students.
Chaminade President Dr. Lynn Babington welcomed Rachel Arakawa ’20 back to campus this month for an informal discussion with students.

Discipline and academic rigor, though, weren’t new to Arakawa. At the beginning of her sophomore year, the Kaneohe native decided to formally enter into an Articulation Agreement between Chaminade and George Washington University’s School of Medicine and Health Sciences.

At its essence, an articulation agreement document is a formal arrangement between two colleges or universities, outlining a structured transfer plan for specific program offerings. Depending on the program and degree, students have the opportunity to initiate their path towards advanced studies as undergraduates. This involves building a robust academic record and fulfilling prerequisites during their time at Chaminade. The agreement benefits students by guaranteeing the transfer of all completed classes (credits) and providing a clear pathway for ongoing academic progression.

Students who want to take advantage of participating in an articulation agreement, for example with George Washington University, should apply in January of their sophomore year. “This timeline avoids any gap year between undergraduate and graduate programs,” Noguchi noted. “Applicants are required to have spent two years (four semesters) in an undergraduate program of the contractual college and to have completed approximately 60 semester hours of course work by the end of the semester during which they apply.”

Articulation agreements streamline the transfer process for everyone involved. This will help alleviate the stress surrounding the application process, the credit transfer process, and several other issues students might encounter when applying to a graduate program. By simplifying this process with transfer agreements, it is beneficial to all parties involved.

Third year bio-medical major, Joshua Dumas ’25, plans to go to med school even though he didn’t pursue an articulation agreement. The aspiring physician’s decision was based on his preference to attend a school on the west coast so he can be closer to Hawaii and family.

“I was studying all winter break for the MCATs, but I decided to wait until I was better prepared,” said Dumas, a Regent Scholarship awardee and COPE Health Scholar with Adventist Health Castle. “It was inspiring to hear how her Chaminade experience helped her in med school, as I am sure it will help me.”

Now in her fourth year and two of three medical licensing exams behind her, Arakawa has applied to various residency programs and received 20 interviews. Her choice of post-graduate training will be in emergency medicine, a specific area that she has been interested in ever since she started her academic track in the health field.

“I did a lot of event medicine, like at concerts and marathons, and I really enjoyed it,” Arakawa told the students. “I get to look at trauma, but it’s not for everyone. You’ll have to find your own passion and specialty.”

Asked by sophomore Ku‘ulei Koko ’26 if she ever experienced the impostor syndrome, Arakawa unhesitatingly answered yes. “I am a first-generation medical student and the only Hawaiian–Japanese in my class,” Arakawa added. “Some of the other students were also more familiar with the social cues and mores of the medical field since they weren’t first gen. But, I overcame impostor syndrome by not comparing myself with others, and got involved with activities that I liked.”

Healthcare is indeed the perfect complement to Chaminade University’s mission. As a Marianist institution, faculty members educate their students to embrace adaptation and change, family values and community service, which are all core components of our healthcare system. And as a liberal arts school, Chaminade ensures that graduates have a wide breadth of knowledge and are able to think critically across a range of disciplines.

“I learned a lot during my years at Chaminade years—inside and outside of the classroom,” Arakawa said. “The small class sizes and the supportive faculty helped shaped my belief in serving the community and being an empathetic individual that can make a transformational impact.”  

Cybersecurity Workshop

Expert warns of maintaining healthy online hygiene

Similar to what you would hear at a dentist office, Liam Wesley dispensed advice about the importance of daily hygiene during a Cybersecurity Workshop at the Data Science Center in Tredtin Hall. But for the cybersecurity expert, this means never using the same username nor the same password ever! Just like you would never keep using the same strand of floss.

In an era dominated by digitization, Wesley described the importance of robust cybersecurity measures that cannot be overstated. As online users navigate an increasingly interconnected world, the guardians of our digital realm are facing new challenges and adapting strategies to protect against evolving cyber threats. Wesley is among them fighting the digital perils.

The 90-minute Cybersecurity Workshop was hosted by the National Science Foundation ALL-SPICE Alliance, which includes the United Nations CIFAL CENTER of Honolulu, Information Technology and Services Department (senior director Jules Sukhabut), the Networking Department (director Joseph Rosario), Data Science, Analytics and Visualization Program (director Rylan Chong, Ph.D.) and the Computer Science Department.

“We brought in Liam to demonstrate real cyberattacks, and discuss how a student can protect themselves for educational purposes and build awareness,” said Chong, Co-Principal Investigator of the National Science Foundation’s Alliance Supporting Pacific Impact through Computational Excellence (ALL-SPICE) grant. “Joe and I plan to pilot this cybersecurity workshop to Natural Sciences and Mathematics students to gauge interest. This will help us understand if there is interest for future workshops, larger workshops and/or a need for a cybersecurity course or program.”

Cybersecurity experts, like Wesley—a penetration tester and cybersecurity engineer with High Tech Hui, LLC and Cyberruptive—warn of the escalating sophistication of cyber threats, ranging from ransomware attacks that cripple essential services to targeted phishing campaigns exploiting the remote work landscape. The proliferation of Internet of Things (IoT) devices—AI voice assistants like the Amazon Echo and Google Home—coupled with the rise of artificial intelligence in cyberattacks, adds a layer of complexity to the battlefield.

In the face of these evolving threats, organizations are doubling down on best practices to fortify their defenses. This includes regular employee training to recognize and thwart phishing attempts, implementing multi-factor authentication, and keeping software and systems up-to-date with the latest security patches.

“Patching is absolutely necessary,” Wesley said. “But wait a few days to avoid the potential for buffer overflow, which are memory storage regions that temporarily hold data while it is being transferred from one location to another.”

Initially limited to Rosario’s computer science networking class, the workshop was eventually opened to all Natural Sciences and Mathematics students due to the importance of the topic and the large interest from Chong’s previous presentation on the topic.

One of the workshop’s primary goals was to bring awareness and introduce education innovation. Chong explained that the topic is very important for the University’s DSAV, CS and NSM students, as many of them are doing research, working with data and sensitive data at various organizations for jobs and internships, and using computers.

“Instead of traditionally just bringing in someone to talk about cybersecurity in general, our goal was to make this relevant to the students to build awareness, address on the national security level the lack of cybersecurity education in schools, and an approach to work on better securing our campus,” Chong said. “In addition, we are planning to take an innovative educational approach by actually demonstrating how easy it is to hack and simulate how bad a cyberattack can be to an organization.”

The landscape of cybersecurity is indeed dynamic and ever-evolving. Experts agree that a collaborative, proactive approach—comprising technological innovation, regulatory compliance and ongoing education—is essential to safeguarding our digital world against the relentless tide of cyber threats.

“There was a lot of information, which was hard to keep up with,” said data science and visualization major LaVelle White ’26. “He explained pretty well how hackers get into systems, even though I can’t hack, but I understood the concept.”

Student Athlete

Haley Hayakawa ’24 has all the bases covered

Haley Hayakawa gets sworn in at the Kapolei field office of the Federal Bureau of Investigation.
Accepted into the FBI’s “Honors Internship Program,”Haley Hayakawa gets sworn in at the Kapolei field office.

Her fellow classmates think she’s playing Candy Crush on her laptop. But in actuality, Haley Hayakawa ’24 is eyeing her Google calendar, which is scattered with different colors, each representing a lab, class or work hours that she has committed to during the week.

When the California native is not in a class or lab, she’s out in left field, shagging flies as a member of the Women’s Softball team. And during the summer, Hayakawa was working 40 hours a week at the Federal Bureau of Investigation’s field office in Kapolei, where she participated in the “Honors Internship Program,” which only accepts a sliver two percent of all its applications.

“It was my first full-time job,” said the 22-year-old Forensic Science major. “It has been the best experience I’ve ever had; everybody there wants to be there, and they all want to help you.”

An avid softball player since the eighth grade, Hayakawa committed to Chaminade University when she was a junior in high school, the earliest a student athlete can officially commit to a Division I or Division II college. 

“I was recruited by Division I and Division II schools, but some wouldn’t allow their recruits to participate in sports if they plan to major in a hard science because of all the required labs,” Hayakawa said. “Chaminade does, and it’s one of the reasons I chose to come here.”

She was also familiar with Chaminade’s Forensics Science program, which requires its students to complete a rigorous, 135-hour internship with such offices as the Honolulu Department of the Medical Examiner, police departments in Hawaii and Guam or the Joint POW/MIA Accounting Command’s Central Identification Laboratory. 

“During my junior year, I interned with the Medical Examiner Department, which gets involved with deaths as a result of violence, substance abuse, trauma, accidents or suicide, among other suspicious causes of death,” Hayakawa explained. “After reading some of the suicide notes, I was thankful to be stressed out because those notes helped put things in perspective for me.”

An ambitious go-getter from an early age, Hayakawa is the only child and holds high expectations from herself—and not her parents, Greg and Myra Hayakawa. In fact, her father often tells her “to be open to changes, and not everything happens as planned.”

“In my freshman year, all I could eye was being awarded summa cum laude, which requires a 3.96 GPA,” Hayakawa notes. “I’ve only had one B and that was in Organic Biochemistry, which lowered my 4.0 GPA to 3.96.”

Ironically, one of her two American Chemical Society awards was being recognized as the Most Outstanding Student in Organic Biochemistry—despite her B—and Most Outstanding Student in Forensic Chemistry, nominated by David Carter, Ph.D., Forensic Sciences director and professor.

“She also has minors in Biochemistry and Chemistry,” Carter says. “She is a stellar athlete on the softball team and she also works as one of our Forensic Sciences Laboratory Assistants.”

Hayakawa’s collegiate experience has certainly had its challenges. Her freshman year was during the height of COVID, which meant Hale Lokelani Residence Hall was in lockdown mode, limiting her interaction with fellow students except for her roommate Naomi Noguchi from Kauai. It was also her first time living away from home, and she couldn’t leave campus for three weeks. Meanwhile, the softball team couldn’t take to the gym and was forced to conduct its workouts via Zoom videos.

“My classes were from 8 a.m. to 5:30 p.m. on Mondays, Wednesday and Fridays, which was crazy,” Hayakawa recalls. “I was so overwhelmed, and when I went home for the winter break, my parents asked if I was OK because I had lost 30 pounds.”

When she returned to campus in the spring, Hayakawa now had to juggle between her softball season and her studies, maintaining a batting average of .377—earning her the team’s batting champion— and a perfect 4.0 GPA. 

“It’s easy to manage time, when your time is managed for you,” Hayakawa quips. “I’m all in … all the time.”

As she completes her final year as a Silversword, Hayakawa fondly reflects back on her time on Kalaepohaku campus, on the softball field, in the labs and with her friends. She already has future plans to attend graduate school, after having turned down a job offer with the FBI field office in Kapolei. 

“I’ve always wanted to help the community through criminal justice,” says Hayakawa, who will graduate as summa cum laude, thus achieving her ultimate freshman goal. “I made the right decision to come to Chaminade, not only because of its small class sizes, but because I got to form relationships with my professors and formed new friendships.”
