For doctoral student Tzu-Chun Chu, the impactful mentorship she has received at UGA College of Public Health has played a huge part in fueling and sustaining research passions that lie at the crossroads of cardiovascular health, infectious diseases and machine learning.
What is your educational and professional background?
I initially earned a bachelor’s degree in horticulture from National Taiwan University and later transitioned into biostatistics while obtaining a Master of Public Health degree from the University of North Texas Health Science Center. Before beginning my doctoral studies, I worked as senior biostatistician for two years at Brown University. My work there involved assisting clinical and translational investigators in supporting the creation of study designs and statistical analysis plans, as well as implementing advanced data modeling to enhance diagnostic and long-term clinical outcomes within the realms of infectious diseases, global health and personalized decision-support tools.
What particular area of public health are you passionate about?
My research passion lies at the crossroads of cardiovascular health, infectious diseases and machine learning. I have accumulated six years of professional experience focusing on infectious diseases, with a particular emphasis on HCV, Ebola, acute diarrhea and COVID-19. My work has revolved around strategies for prevention and early treatment initiation, as well as addressing intricate issues related to health disparities. During my time at Brown University, I also led the analysis of a N-of-1 trial study to test individualized triggers for atrial fibrillation, a type of heart arrhythmia that can lead to various heart-related complications, with the aim of improving quality of life. This marks my very first exposure to cardiovascular research. These experiences have fueled my growing interest in continuing my endeavors in these vital areas.
What exciting projects are you working on?
I am currently working on a project led by EPIBIO faculty members Jessica Knight and Allan Tate that employs wearable devices and mobile apps to gather health data, including heart rate variability, physical activity and sleep patterns. Our research focuses on identifying stress patterns and disparities, especially within low socioeconomic status families. This work aims to inform targeted interventions to enhance cardiovascular health outcomes among both teenagers and mothers. I am enthusiastic about advancing this project to explore how momentary stressors impact both parents and children within a real-world, non-laboratory setting, examining the cycle of stress and its effects on mental health.
What attracted you to getting your doctorate at the College of Public Health?
I was drawn to pursue my doctorate at the College of Public Health due to my deep passion for statistical methodologies, modeling and epidemiological research. The department of epidemiology and biostatistics provides a course curriculum, environment and research opportunities that specifically emphasize the comprehensive aspects of both disciplines. Another thing that really captivated me was its proven track record of being a truly supportive and diverse community. I’ve worked on various projects alongside dedicated faculty, fellow students and clinical researchers, and each experience was nothing short of remarkable.
These collaborations let me explore different aspects of public health, contributing to my personal and professional development. It’s been an incredible opportunity to apply and expand upon my background in such a dynamic and impactful environment.
What achievements or honors during your time at CPH are you most proud of?
I appreciate the opportunity to present our research findings at various national and international conferences. One achievement I value is the acknowledgment of our research project on the heterogeneity of childhood obesity in diverse households, featuring a machine learning-informed intervention. This collaborative effort involved our department and the Family Matters Georgia team from the University of Minnesota, and it received recognition at The Obesity Society. This acknowledgment underscored the importance of our work and facilitated valuable discussions and collaborations within the academic community.
Do you have any external activities that you are passionate about?
Outside of my research, I love hitting the road with my husband, friends and Leia, my 9-year-old lab retriever mix. She’s always up for a good adventure. I also love baking, painting, watching movies and stand-up comedy.
What are your career plans beyond graduation and what will you take with you from your time at CPH?
After graduation, I look forward to continuing my focus on cardiovascular and infectious disease research due to their significant global health impact in the biomedical industry. Connecting with dedicated professors and researchers who took a genuine interest in my academic journey has been transformative. Their guidance not only enhanced my understanding of epidemiological research but also fueled my resilience and passion for contributing to public health. I truly appreciate everything I have encountered during my time at the College of Public Health.
