‘CSI: Chandler’? Alumna Doss Could be the Star

A love of science and a fascination with the “CSI: Crime Scene Investigation” television franchise drew Chelcey Doss to Chaminade University of Honolulu.

Now, after earning her Forensic Science B.S. degree in 2015 with a minor in Chemistry, Doss does more than watch CSI shows on TV. She’s out in the field conducting official crime scene investigations for the Chandler Police Department in Arizona.

CSI work is “not quite as glamorous” as Hollywood portrays it, admits Doss, who just marked her one-year anniversary with the police department. But CSI is a rewarding career that’s vitally important to public safety and the criminal justice system.

What’s the biggest difference between academia and the professional world?

“You’re seeing real people,” Doss says. “And usually it’s not a good day for them.”

Fortunately for the approximately 261,000 Chandler residents, the city’s violent crime rate is relatively low.

“We only had four homicides last year,” Doss points out. “And that was actually high. There are lots of property crimes – vehicle burglaries, house burglaries. A lot of the calls that come across are domestic violence or drug-related.”

Looking back at her time on campus, Doss describes Chaminade as “an amazing experience.”

“I loved the diversity,” she says of college life. “And I really enjoyed the professors,” including Dr. David Carter, director of the Forensic Sciences Unit. “They are very in tune with what students need.”

“I want to say ‘thank you’ to Chaminade for helping me get to where I am today,” Doss adds. “I’m very grateful.”

The Forensic Science program is part of the Division of Natural Science and Mathematics. It provides students with a wide range of options as they prepare for careers in fields such as law enforcement, medicine, dentistry, pharmacy and veterinary medicine. Since 2010, 86% of graduates have been placed in science-related positions. Chaminade University offers two credentials in forensic sciences education: a Bachelor of Science in Forensic Sciences (BSFS) and a Minor in Forensic Sciences.

Forensic Students Present Research at National Conference

Based on their discoveries in the field of carcass decomposition, Chaminade University students Hannah Dibner and Chelsie Mangca Valdez were invited to present their research at a national conference held by the American Academy of Forensic Sciences (AAFS).

The academy’s 69th Annual Scientific Meeting, scheduled for February 13-18 in New Orleans, brings together professionals in all areas of forensic science, including criminalists, physicians, toxicologists, anthropologists, dentists, physicists, psychiatrists, engineers and educators.

Dibner and Valdez, who will both graduate in Spring 2017 with a Master of Science in Forensic Sciences, decided to partner on their research into the biology and pathology of how pig carcasses decompose.

Dibner focused on the effects of scavenging by the Small Asian Mongoose. She points out that this type of research is important because wounds created by scavengers could be mistaken for trauma from violence. Also, knowledge of scavenger behavior could help search parties more effectively locate and recover human remains.

“Studying rotting carcasses may not be everyone’s idea of a good time,” Dibner says, “but to me it’s a dream come true. The decomp studies at Chaminade are asking certain questions that we haven’t seen addressed by anyone else. And as a scientist, that’s an incredibly exciting and unique position to be in.”

Valdez studied the skin chemistry of decomposing pigs. Her research may lead to a new technique for determining Post-Mortem Interval, meaning the amount of time that elapses after a person dies.

“The thing I am most excited about regarding the AAFS conference is the opportunity to meet professionals in the field I have committed seven years of my life studying,” Valdez says. “This experiment was very time consuming but it was very much worth it,” she adds. “I never thought I would be attending a national conference, let alone presenting my finding all while still attending college.”

Dr. David O. Carter, director of Chaminade’s Forensic Sciences Program, encouraged Dibner and Valdez to submit their research to AAFS.

To help students achieve their academic and career goals, Chaminade University’s Office of Health Professions Advising and Undergraduate Research coordinated professional development workshops conducted by officials from A.T. Still University (ATSU).

Under formal articulation agreements, Chaminade students gain early admission to health profession programs at ATSU campuses in Arizona and Missouri with degrees in osteopathic medicine, dentistry, audiology, physical therapy and occupational therapy.

The Jan. 31 workshops focused on what the ATSU admissions committee looks for in applicants and how to communicate effectively during the interview process. ATSU administrators also led an informational session on Feb. 1 to give students an overview of educational opportunities.

For Adam Perez, a Biochemistry major graduating in Spring 2019, the biggest takeaway from the admissions workshop was that ATSU looks at all aspects of applicants. This means it’s important “to truly understand who you are” when applying for medical school.

Melissa Ponce, a Biochemistry major graduating in Spring 2018, credits the interviewing skills workshop with helping her “see my unconscious quirks.”

“I realized through this workshop that all the questions the interviewer asked were all questions that I had the answers to,” Ponce says. “It’s all a matter of being genuine and  honest with not just the interviewer but myself as well.”

Before departing Oahu, ATSU Vice President for Admissions Dr. Dave Koenecke toured the Waianae Coast Comprehensive Health Center, which partners with Chaminade to provide affordable medical care to underprivileged residents, including many Native Hawaiians.

Through an articulation agreement, 2012 Chaminade graduate Ashley Baldauf enrolled in the osteopathic medicine program at ATSU’s Arizona campus in 2013 and is spending three years studying and working at the Waianae center.

Office of Health Associate Provost Patricia M. Lee-Robinson reports that eight Chaminade graduates are currently enrolled in ATSU programs.

Chaminade also has articulation agreements with Boston University School of Medicine, George Washington University School of Medicine and Health Sciences, Pacific University, Samuel Merritt University, Tufts University School of Dental Medicine, University of Dayton and Western University School of Health Sciences.

Chaminade Now Accepting Applications for Ho’oulu STEM Scholarships

Chaminade University is currently accepting applications for its full-tuition Ho`oulu STEM (Science, Technology, Engineering, and Mathematics) Scholarships. The scholarships are open to first-year and transfer students and give preference to applicants of Native Hawaiian ancestry. Apply now for early consideration. For more details on the Ho`oulu STEM Scholarship, visit the Ho`oulu STEM Scholarship webpage or call (808) 739-8551.

In partnership with Kamehameha Schools, Chaminade University created an opportunity for students pursuing a Bachelor of Science degree to receive full tuition assistance (100%) and the opportunity to apply for living expense assistance for four years. It also provides wraparound academic support services, access to post-graduate career paths via Chaminade’s suite of articulation agreements, paid internships for professional development, and financial support for career development activities.

Hooulu STEM Scholarship, First Cohort

In the fall of 2016, Chaminade University welcomed its first Ho`oulu cohort of first-year and transfer students in the following Bachelor of Science degree areas: Biology, Biochemistry, Forensic Sciences, Environmental Studies, Nursing, and Pre-Med/Pre-Health.

“The impact of Ho`oulu is far-reaching,” said Chaminade President Bro. Bernard J. Ploeger, SM, Ph.D. “Careers in STEM-related fields are projected to be some of the fastest growing segments of tomorrow’s workforce.”

Chaminade’s Dean of Natural Sciences and Mathematics Helen Turner, Ph.D. agreed. “Solutions to health, environmental and justice challenges are to be found in science and technology, and we envision Ho‘oulu students leading the community in the future to strengthen the lāhui.”

Forensic Sciences Scholar Joins Chaminade Faculty

Dr. Katelyn PerraultThe Division of Natural Sciences and Mathematics welcomed to their team this academic year Dr. Katelynn A. Perrault, assistant professor of Forensic Sciences and Chemistry. Dr. Perrault has expertise in the use of gas chromatography (GC) and comprehensive two-dimensional gas chromatography (GC×GC) across a range of life science applications, including, primarily, forensic science. She has done extensive work profiling the volatile organic compounds (VOCs) that form the odor evolved from decomposing remains. Such work is essential in understanding the sensory mechanisms behind scent-detection canine use.

In 2011, she earned her Bachelor of Science degree with Honors in Forensic Science from the University of Ontario Institute of Technology. “Graduating with my undergraduate degree was a very proud moment. I remember thinking that this was only the beginning of a really exciting journey and that there were endless possibilities ahead,” she said.  “That was also when I decided that I wanted to become a professor one day, so I could help students feel that same sense of achievement and help guide them along the path to their fullest potential.”

With that in mind, Dr. Perrault would need to go beyond her comfort zone. Her doctoral studies meant traveling a great distance. “I moved to Australia to pursue my Ph.D. It was a pretty important defining moment in my life. I had hardly ever traveled and never really thought much about it. I ended up meeting people from all over the world and was lucky enough to do a fair bit of traveling during my degree. Making that decision to move has made me more resilient and independent over time, but my experiences during my degree also gave me a profound appreciation for other cultures,” Dr. Perrault said.

Achieving her Ph.D. with a focus in Forensic Chemistry in 2015 from the University of Technology Sydney, Dr. Perrault went on to perform additional doctoral studies at the University of Liège, applying novel analytical approaches to challenging matrices in various fields such as food science, archaeology, and forensic science. Through her research and travels, she has cultivated an international network of collaborators in academia, police, and government agencies.

This semester Dr. Perrault teaches undergraduate and graduate courses in forensic chemistry, general chemistry, analytical chemistry and instrumental analysis here at Chaminade University. Her research program at Chaminade focuses on sensing VOCs from various biological sources for medical and forensic applications. She is also a peer reviewer for several forensic science and chemistry journals and has presented at numerous international conferences.

“One of the main reasons that I decided to come to Chaminade was the sense of community on campus. It was evident from the first moment I visited, and I am so pleased to now be part of this community,” noted Dr. Perrault.  “I look forward to developing meaningful relationships with my students and contributing to their career success out in the community.”

Chaminade Welcomes Middle School Students with Science

Chaminade University recently hosted students from Stevenson Middle School for a half-day as part of the College for Every Student (CFES) program. Dressed in their Chaminade-logo wear, student and faculty volunteers greeted 40 eighth graders and their escorts on the morning of November 18, as the young students climbed out of a yellow school bus in front of Clarence T. C. Ching Hall.

Stevenson Middle School students doing a science activityThe youth and their escorts were divided into two groups.  While one group toured the campus, the other group attended an “I am a Scientist” session hosted in the Henry Hall laboratories by Lori Shimoda, faculty member and research associate from the Division of Natural Sciences and Mathematics. Shimoda, who created the “I am a Scientist” program that has inspired thousands of students in Hawaii with science, coordinated the activities with graceful effectiveness.  Cheerfully she and her colleagues encouraged critical thinking and puzzle solving for the youth in white lab coats.  When done, the science group switched with the tour group.

Once everyone had completed the science session and the tour, it was lunch and reflection time. Chaminade volunteers led the Stevenson students in CFES-based activities helping the youth to reflect on the future probability of someday attending college with Chaminade as a top-of-mind possibility.
