Chaminade Hosts Pacific Region Data Science Challenge

May 17, 2022 by University Communications & Marketing

Rewarding. Difficult. Inspiring. Those were some of the words student participants used to describe their experiences in the inaugural Advanced Computing for Social Change Challenge in the Pacific, hosted earlier this spring by Chaminade University’s Data Science, Analytics and Visualization program.

Dr. Rylan Chong, director of the program, said about 20 students from across the Pacific—including Saipan and Guam—participated in the remote, week-long event along with six undergraduate mentors.

The challenge in March was held in coordination with similar events scattered across the country, Chong said, and with support from Extreme Science and Engineering Discovery Environment (XSEDE) and Texas Advanced Computing Center, whose supercomputer was used by student participants.

Chong said the challenges are meant to test participants’ data analysis and interpretation skills, creativity, innovation, and ability to work under pressure. Participants also get invaluable training and mentorship—all as part of a broader effort to help them connect real-world data to actionable solutions.

Over the course of the week, students identified a research question, pored over the relevant data, arrived at results, created data visualizations, and then presented their work. Along the way, they also attended workshops on everything from statistics to text mining in order to hone their skills.

He said the projects students worked on included a study of COVID-19 in Hawaii and an exploration of native birds of Haleakala. “Each project provided data sets for participants to derive their project from,” he said. “The data sets included thousands of records and results were used to inform researchers.”

He added that the underlying theme of the challenge was about building capacity and learning communities in the Pacific to “harness the power of technology and data to address” challenges.

Chaminade Data Science student Sarah Carroll ’24 jumped at the chance to participate in the competition to build on her skills and apply them. She focused on COVID-19 in Hawaii, text-mining Twitter data to analyze community sentiment on the virus and the government response.

“It was very rewarding to see that I am capable of implementing what I learned,” Carroll said, adding that she was thrilled to be able to put together a project and get immediate feedback on her presentation. “This experience really boosted my confidence in working with data.”

Punohu Keahi is a first-year student at Chaminade, majoring in Environmental Studies, and participated in hopes of learning more about how to turn big data sets into results that communities can actually use to make decisions. “My biggest reason for joining this program was to step out of my comfort zone,” Keahi said. “Getting this experience is something I will never forget.”

Keahi opted to dive into data from the Haleakala National Bird survey.

“I love native birds and I’m interested in knowing more about the different factors that could have caused the fluctuations in the bird population,” she said. “My biggest challenge during this program was figuring out how to code and then create different scatter plot and bar graphs.”

One of the greatest thrills? Using a supercomputer for the first time.

Armando Luna, a Data Science student at Chaminade, said the competition was tough—but a worthwhile experience. “The biggest challenge was ensuring I would have a presentable and complete project in time,” Luna said. “However, we had fantastic mentors who helped us through the week.”

Mentors like Dairian Balai ’22, who said she wanted to volunteer because of her own positive experiences at Advanced Computing for Social Change Challenges on the mainland. She was in the 2019 ACSC cohort and said the mentors were key to ensuring the event was filled with both learning and fun.

She said many of the students participating in this year’s challenge didn’t have any experience with coding, programming or working with big data sets. That meant they needed some extra help to ensure they didn’t get overwhelmed. “The students persevered and created incredible posters,” she said.

She added that what she enjoyed most about being a mentor was watching students grow in the challenge. “You can tell how much confidence they gained,” Balai said. “I also like seeing those great ‘aha!’ moments when they’re running into issues and then they finally make a breakthrough.”

Student Wins SC21 Data Science Competition

Taylor Ishisaka loves to unlock the secrets hidden in data.

There’s nothing more satisfying or rewarding, she says, than translating big data sets into clear, actionable information that communities can use to understand themselves better or tackle existing problems anew. “The world of data science has so much to offer,” said the Chaminade senior.

That passion isn’t only infectious, it’s getting noticed.

Most recently, she was part of a team that took home top honors in the inaugural data science competition at SC21, one of the biggest international conferences on high-performance computing. The competition, held over two phases in October and November 2021, was designed to give students a chance to showcase their computing, problem-solving and data analysis skills in a team dynamic.

Ishisaka, who is a Ho’oulu Scholar and Data Science major at Chaminade, said the competition started with a meet-and-greet opportunity over Zoom followed by details on the expectations for participants. She was put into a team with students from around the nation, including Washington State University and Central Texas College.

The first phase of the competition required students to perform analysis on a data set using a high-performance computing cloud. Ishisaka said the task was designed to test participants’ time management skills, teamwork, and ability to work effectively in the cloud platform.

The data set was a compilation of agricultural and livestock data from the U.S. Department of Agriculture database. Ishisaka’s team looked at crop production and fertilization data over several years, and Ishisaka created a color-coded heat map showing changes over time. A teammate, meanwhile, crafted several graphs that showed crop and soy production over specific Census years.

Ishisaka and her teammates put together a report in order to move to Phase 2, during which participants were challenged to find their own datasets to highlight problems in specific regions. Ishisaka’s team focused on Missouri data, specifically looking at data on bison populations. They took a multi-state view, tying in figures on climate and other environmental factors in their analysis.

The challenges were tough enough, but Ishisaka’s team also lost members over the course of the competition. Two didn’t show up again after the initial Zoom session. A third team member dropped off the map in Phase 2. That left the original team of five with just two members.

“As there were only two of us left in the most critical phase, my team member and I met with our mentor for hours each day discussing our progress on the project and next steps,” Ishisaka said. “We had to retrace our steps and rediscover our project purpose in order to put together our presentation.”

It was no easy task—but Ishisaka wasn’t deterred.

“After hours of putting together our presentation and rearranging everything to make sure that our story flowed, we created a product that we were proud of,” she said, adding that she stayed up all night before presentation day so she could memorize her talking points and deliver a clear message.

She delivered the presentation via Zoom with the judges and other teams all there. When everything was done, she was proud to have completed what she set out to do—and wasn’t thinking all that much about whether she’d actually be recognized for her efforts. “I was honestly surprised when we won,” she said. “I attended presentations of the other competitors and their projects were phenomenal.”

Ishisaka said she’s very happy with what she and her teammate were able to accomplish.

“I decided to keep on going throughout the competition because for one, I was representing Chaminade. And secondly, I know that my progress in the competition was a reflection of the skills and values that I learned throughout my academic journey in data science,” she said.

Ishisaka added she’s not one to leave things unfinished.

“Once I commit to a project, I am in it for the long haul,” she said.

The same goes for her commitment to data science, a major she fell into after participating in the Supporting Pacific Indigenous Computing Excellence (SPICE) Summer Institute in Summer 2019. SPICE, a partnership between Chaminade and the Texas Advanced Computer Center, gives students from all different majors and backgrounds a chance to explore data science and its many applications.

Ishisaka said that she entered the SPICE program not knowing anything about data science, “or that it even existed.” She added, “The following semester, I went to academic advising and switched my major from biochemistry to data science, and honestly it was probably one of the best choices I ever made.”

Students’ Stress-Related Project Awarded First Place in National Competition

November 5, 2021 by University Communications & Marketing

Stress is a fact of life, but two innovative Silverswords want people to know the story doesn’t end there.

And their work is getting wide recognition.

Aloha Lei Garo and Taylor Ishisaka with their first-place medals

Earlier this year, Aloha Lei Garo ‘22 and Taylor Ishisaka ’22 embarked on a research project aimed at helping their fellow students recognize when their anxiety levels were getting too high and giving them new tools to manage stress, build resilience and seek out opportunities for self-calming and reflection.

The two then spent long hours preparing to present their research at the HOSA-Future Health Professionals’ Virtual International Leadership Conference over the summer. The event features a competition with postsecondary students from around the nation and the globe, all spotlighting their work and detailing its potential implications for the field. Garo and Ishisaka were pleasantly surprised by all the positive feedback they got — and then were even more wowed by their first-place win.

The two took home the top prize in the Health Education category.

The title of their project was “Finesse Your Stress,” and included self-assessments for students, information on why stress can impact your overall health and easy activities anyone can do — from fun games to movement exercises to guided meditation — aimed at boosting resilience.

The presentation also included guidance on when to get professional help.

Lei Garo is studying Biology at Chaminade while Ishisaka is pursuing a degree in Data Science. Both got involved in HOSA (Health Occupations Students of America) and its leadership development programming in high school and have remained active members at Chaminade.

“I was very shocked and surprised that we won first place in our category,” Lei Garo said. “It was wonderful to see that all of our hard work has paid off to have this moment for us. I’m glad to not only have represented Chaminade University but also the state of Hawaii.”

Ishisaka added she’s hoping to continue sharing their research and positive message more broadly, including “just how important it is to take care of yourself because we all get stressed. It is something we all face and it is vital to take control of it. It was our goal to educate young adults on the meaning of stress, how to recognize it and supply them with resources so they can maintain a healthy lifestyle.”

Ishisaka also said they had to remember their own advice as they put together their presentation, especially in overcoming no shortage of obstacles presented to them by COVID. Because of the pandemic, they had to prepare remotely and frequently chatted with each other over Zoom.

“We adapted to every obstacle,” she said.

“And started to expect the unexpected,” added Lei Garo.

Lei Garo said she wants her fellow students and the broader community to know taking breaks and caring for your mental health is just as important as doing well in school or succeeding in sports. “We get so caught up in the moment that we forget we should stop for a bit and take care of ourselves,” she said. “Taking at least a 10-minute break from stress is sometimes all you need to rejuvenate.”

Data Science SPICE Summer Institute

August 18, 2021 by University Communications & Marketing

For a third year, budding data scientists from across Hawaii and the mainland came together for Chaminade’s Supporting Pacific Indigenous Computing Excellence (SPICE) Data Science Summer Institute.

2021 Data Science SPICE Summer Institute virtual class meeting

The 2021 program, held virtually, included 21 participants and four student mentors. In addition to Chaminade, students hailed from Stanford University, Borough of Manhattan Community College, the University of Hawaii Maui College, College of the Marshall Islands and Northern Marianas College. They also came from a diversity of academic backgrounds, from Nursing to Environmental Studies to English.

The month-long seminar is focused on helping students use data as they seek to make a positive difference in their communities and includes immersive experiences, collaboration and a final project. Institute organizers say students walk away not only with new skills, but with a new appreciation of how data science can be used across disciplines to help spotlight problems and highlight potential solutions.

SPICE is held in partnership with the Texas Advanced Computing Center. Program leader Dr. Kelly Gaither is associate director at the center. Other faculty who helped make the institute possible include Chaminade Assistant Professor Dr. Rylan Chong, director of the University’s Data Science program, and Chaminade Vice President of Innovation Dr. Helen Turner, who is also a professor of Biology.

Students took up all sorts of questions and issues in their final projects for the SPICE institute, from socioeconomic factors linked to heart disease in Hawaii to the potentially positive relationship between video games and social anxiety to the impacts of wildfires in California on chronic diseases.

The overall project and poster winner was Chaminade student Sarah Carroll, who looked into whether the long-term impacts of food security in the United States include higher rates of chronic disease. Using publicly available data sets, she mapped out food insecurity in the US and found a slightly positive correlation between food insecure individuals and rates of arthritis, asthma and cancer.

She noted further study is needed to determine what’s driving chronic diseases in food insecure populations, along with which US ethnic groups have the highest rates of inadequate food access.

There were also three track winners named.

In the healthcare track, Chaminade student Caili Cain took the top prize. She sought to investigate implicit bias in the medical field, including how medical school pedagogy might be endorsing false beliefs about biological differences between Black and white patients. Specifically, she was interested in how official and informal medical school curricula contribute to bias about how patients manage pain.

Chaminade student Rhea Jose was the track winner for Environment, with a presentation that explored whether food availability and consumption in the US can show food loss or waste. She said the next step in her research might include investigating food waste per capita in order to make local level changes. And Chaminade’s Amber Sablan was recognized for her social justice-focused presentation. In her project, she sought to determine whether gentrification on Oahu could be contributing to homelessness by driving up home prices and bringing in new higher-income tenants. She said the lack of available data from 2020 limited her research, but she is interested in furthering her study into the issue. More specifically, Sablan wants to look at the number of unoccupied homes on Oahu along with outmigration rates.

Chaminade University’s “Community First” Approach Sparks an Innovative Data Science Collaboration

July 24, 2021 by University Communications & Marketing

A Collaborative Vision: Waianae Coast Community Scorecard and Dashboard Project

As part of an innovative partnership, Data Science students at Chaminade University are teaming up with community groups in the Waianae Coast to develop a Waianae Coast Community Scorecard and Dashboard. This project is designed to be regularly conducted to measure community sentiment and report results that are easy-to-use, meaningful and actionable. The results will shine a spotlight on areas of opportunity and community wellbeing, and will help prioritize initiatives. Dr. Helen Turner, vice president of Chaminade’s Center for Strategy and Innovation and faculty of the Data Science program says, “this project is part of a broader vision that embraces Chaminade University’s ‘community first’ approach and the work done at the Center to foster an Innovation Moku in the Waianae Coast to build a refreshed economic reality that is resilient and fits with community priorities and wishes.”

This project is advised by Dr. Rylan Chong, director of the Data Science program and assistant professor at Chaminade University and by Joseph Lapilio, the executive director of the Waianae Economic Development Council and Waianae Moku Navigators.

Joseph Lapilio says “the Waianae Moku Navigators, made up of more than two dozen community organizations, is excited about the Chaminade Innovation Moku partnership and the prospect of having a reliable—and replicable—tool for gauging public opinion, welfare, wellbeing and key quality of life metrics in the Waianae Coast. A lot of what we do now is based on anecdotes or emotional reaction to issues going on. But actual data,” Lapilio said, “has power that could incite real action.”

The Partnership: Working, Learning, and Growing Together

The Waianae Coast Community Scorecard and Dashboard project was first piloted in fall 2020 and continued through spring 2021. Students enrolled in the Data Science 301: Community-Engaged Computing class worked with the Waianae Moku Navigators and the Waianae Economic Development Council to create an initial scorecard and dashboard.

Lapilio said he’s been “very impressed with how hard Rylan and his students have worked on the project. Rylan has been extremely open to community input,” he said. “Our long-term goal is not only in terms of a scorecard. It is also in terms of—how do we connect community members to data collection so it is more than just us? How do we work together? How do we connect?” The scorecard hasn’t merely been an academic exercise, but a growing experience for Chaminade students and for members of the community. “They need to be able to engage with the community, to see the community as a partner in this work,” Lapilio said.

The next step for this project is launching the initial scorecard to a test group before taking the scorecard community-wide to collect responses. The scorecard incorporates a host of data points, including information on food security, household income, housing, health, feelings about safety, technology infrastructure and acceptance, and a sense of belonging.

The Experience: Hands-On, Collaborative, Meaningful

Dr. Gail Grabowsky, dean of the School of Natural Sciences and Mathematics at Chaminade says, “real-world projects and partnerships like the Innovation Moku get our students involved and allows them to apply their data science skills in a collaborative environment to address the wellbeing of their communities.” Chong adds, “the Waianae Coast Community Scorecard and Dashboard project is about providing the students with a taste of what data science can actually do and the positive impacts they could have in the Data Science discipline.”

Students participating in this project say the effort has been fulfilling.

“My biggest takeaway from the project was how far-reaching an effect data science can have,” Chaminade Data Science senior Aaron Walden said. He assisted with the effort in Fall 2020 and said it helped him understand how “data science can be used to identify community initiatives.” The scorecard, he said, “is a tool to visually see trends to support prioritization of the community initiatives.”

Senior Hunter Yamanaka, who is majoring in Biochemistry with a minor in Data Science, also participated in the scorecard and dashboard project in Fall 2020. He said “working with the community while digging into the numbers helped him understand how similar efforts could benefit organizations and the public. Data Science has endless ways of improving society,” he said.

“For instance,” says Data Science major Taylor Ishisaka, “data science can turn lists of data points and numbers into something visual and meaningful that everyone can understand. It can shape how we see the world.” Ishisaka, who participated in the scorecard and dashboard project Spring 2021, said “it has been eye-opening to see how much work and collaboration goes into a project like this.” Data science in Hawaii and the Waianae Coast Community Scorecard and Dashboard project is more than collecting data, programming, and analyzing data. When data science is applied to this project, it’s clearly a powerful discipline that can be applied to any field, provide a platform for a community to voice their opinions, inspire discovery and innovation, connect communities, and has the potential to confirm or make ethical societal or policy changes. As Ishisaka and Lapilio said, “when it comes to data science, the possibilities are endless, with real potential for inciting action and implementing positive change in our communities.”

Finding Solutions Through Data Science

March 20, 2021 by University Communications & Marketing

Dairian Balai ’22 peers into data to find solutions. That’s where she found her passion, too.

The Data Science major likes to say that all those numbers—on everything from community health disparities to poverty to race and education—represent people, with hopes and dreams, just like her. She’s on a mission to tell their story (and hers) by spotlighting the data that speaks to real experiences.

“I want to shine a light on the problems we’re facing,” she said.

And even though she hasn’t yet graduated, Balai is already making her mark. Thanks to a series of programs at Chaminade, Balai scored a paid remote internship with a University of Texas lab to research maternal and infant mortality and co-morbidities in Native Hawaiian communities.

She hopes to use data science to spotlight what factors can help protect moms and babies.

Balai grew up in Waiʻanae and graduated from Waiʻanae High. During her junior and senior year, she applied to a long list of potential universities in Hawaii and on the mainland. And she was pretty set on going out-of-state for her undergraduate education. But then her high school counselor told her about the Hoʻoulu STEM Scholarship, which covers 100% of Chaminade tuition and offers support services.

The scholarship convinced Balai to take a tour of Chaminade—and she’s glad she did.

“Off the bat, I liked how it was a small community. The campus was small,” she said, adding that she later spoke to her high school adviser and realized that the financial support offered through the Hoʻoulu STEM Scholarship far outweighed other aid universities on the mainland were offering her.

“I decided to stay. If I went back in time, I would make that decision again,” she said.

Balai said the thing she appreciates most about Chaminade is the one-on-one support she gets from professors and advisers, who have connected her with key opportunities. “They really make it a point to help you plan out your future,” she said. “They say ‘Chaminade is a family.’ I really believe that.”

Balai originally majored in Biology because she planned to go into healthcare.

But the course of her studies changed after she was participated in Chaminade’s Supporting Pacific Indigenous Computing Excellence (SPICE) program. The intensive, immersion experience, in partnership with the Texas Advanced Computing Center at the University of Texas at Austin, is designed to help train students to lead in data science and visualization efforts that support social justice projects in Hawaiʻi.

Balai said she learned coding in the SPICE program and worked with other students to create visualizations that helped illustrate her research area—how socio-economic status impacts healthcare.

From the SPICE program, Balai participated in a Computing4Change event in Chicago. The national competition challenges students to use computing for positive social change. Balai said through SPICE and the Computing4Change conference, she learned that data science wasn’t just about highlighting problems “but helping to solve them.” That, she realized, was the career she wanted to pursue.

So Balai switched majors to Data Science, taking the plunge even though it meant a little more time completing her undergraduate degree. She also started considering how she could eventually bring Data Science home—back to Waianae and the community she loves and eventually wants to serve.

She said Data Science helped her understand that having vulnerable populations doesn’t define Waiʻanae (and other communities with larger concentrations of low- and moderate-income families), but that socio-economic and other factors have a significant impact on the lives of Waianae residents.

She is especially interested in uncovering the factors that contribute to health disparities in her hometown. Data Science solutions to those gaps, she said, will help build a healthier community. And ultimately, that will help build a healthier state and nation, Balai added.

In 2019, Balai was offered a paid internship studying maternal health in Native Hawaiians. She said as a Native Hawaiian, the research feels personal—and all the more important given the healthcare challenges the community faces. She’s continuing that work and hopes to build on it.

In fact, Balai is now planning to go to graduate school.

She’s working with her adviser weekly to consider programs, and on crafting her long-term dream: returning to Waiʻanae to “build a better, a more aware community”—with Data Science.
