Lindsay Kobayashi, PhD
My research focuses on the social epidemiology of cognitive aging from a global perspective. I primarily use data from internationally harmonized longitudinal studies of aging, including older populations of England, Canada, the United States, and South Africa. My current research is on the life course social and economic determinants of cognitive aging in rural South Africa using longitudinal and randomized exposure measures. I am also investigating the population health implications of continually improving cancer survival rates at older ages in the United States. The goal of my research program is to inform policy solutions to improve cognitive health and health equity among low-income older populations.
Outside of work, I enjoy long-distance running, traveling, playing with my dog Zola, and being outside as much as I can!
Megan Mullins, PhD, MPH
Postdoctoral Research Fellow
I completed my MPH and PhD at the University of Michigan School of Public Health in the Department of Epidemiology. My dissertation work focused on racial disparities in ovarian cancer care. I am interested in understanding barriers to the receipt of quality cancer care including patient characteristics, structural barriers and the comparative effectiveness of treatment modalities.
My postdoctoral work will focus on generating evidence to identify gaps in the quality of cancer care among cognitively impaired older adults and understanding functional aging trajectories among cancer patients. More broadly, I am passionate about care for gynecologic cancers with a focus on disparities among racial and sexual/gender minorities.
In my spare time, I enjoy playing tennis and growing succulents.
Brendan O’Shea, MPH
I am a recent MPH graduate in Epidemiology from the University of Michigan, Ann Arbor. I began working with Dr. Kobayashi during my Masters program where she served as my Capstone project advisor looking at the impact of adverse childhood experiences on the rate of memory decline in mid-to-later life. I joined the Kobayashi Research Group following graduation and took part in launching the COVID-19 Coping Study. I currently serve as the main data analyst for the COVID-19 Coping Study.
My research interests include impacts of early-life environment on adult behaviors, and fundamental causes of health inequities.
In my free time, I enjoy photography, acrylic painting, and spending time outside.
Marisa Eastman, MPH
I joined Dr. Kobayashi’s research team in May, 2020 after graduating from the University of Michigan with my Master of Public Health in Global Health Epidemiology. My research interests are numerous and evolving, but have explored topics including emergency medical care in sub-Saharan Africa, traumatic brain injury in the Ashanti region of Ghana, and racial disparities among older US adults in the coordinated care experience. Currently, I am working on projects focused on behavioral coping strategies amidst the COVID-19 pandemic and racial disparities in cancer.
Outside of work I may be found getting lost in the beauty and healing energy of nature, on a long run, perusing an art museum for obscure Dalì originals, or teaming up with my horse for a three-day event.
Haeyoon Chang, MPH
Second Year PhD Student
My name is Haeyoon Chang, and I’m a second-year PhD student in Epidemiology at University of Michigan. I received my MPH in Chronic Disease Epidemiology at the Yale School of Public Health, and my Bachelor’s degree in Biology at the University of Wisconsin-Madison.
I served in the Peace Corps Tonga 2013-2015 where I collaborated with a local medical provider on developing accessible skill-building materials on nutrition to combat the local obesity issues. Additionally, I’ve developed an appreciation for global health research from experiences such as investigating challenges to cardiometabolic management in rural Uganda and examining cardiometabolic disparities among American Indian elders using mixed-methods at Partnerships for Native Health located in Seattle, WA.
Outside of work, I enjoy exploring nature, critiquing ice cream, crafting, and cooking!
Xuexin Yu, MSc
First Year PhD Student
I earned a bachelor’s degree in Biology and a master’s degree in Hospital Management and Health Policy, both from Sichuan University, China. I served as a Research Associate at Biomedical Big Data Center, West China Hospital, Sichuan University for two years before joining Dr. Kobayashi’s research group in the fall of 2021.
I am interested in social epidemiologic patterns of brain health across low-, middle-, and high-income countries. During my doctoral studies, I plan to investigate the cumulative effects of socioeconomic trajectories on cognitive aging among older adults, primarily using international harmonized survey data from South Africa, China, and United States.
I enjoy traveling outside of work.
Tsai-Chin (TC) Cho, MSc
First Year PhD Student
I am a first-year PhD student in Epidemiology at University of Michigan. My research interests revolve around social and contextual determinants of within- and between-country health disparities in older adults; and impacts of neighborhood characteristics on health outcomes and healthcare utilization. I am currently participating in the project focusing on how social and economic factors influence cognitive functions using cross-national comparative longitudinal studies.
Outside of work, I like to read, enjoy tasty coffee with pleasant aftertaste, and go for a walk.
Carly Joseph, MPH
Carly is a 3rd year medical student at Central Michigan University who completed her MPH in Epidemiology at the University of Michigan School of Public Health in 2021. For her MPH capstone project, she investigated the relationship between social isolation and mental health in older adults during the COVID-19 pandemic. She is now continuing work with the research group centered around isolation and mental health throughout the aging trajectory. Her research and clinical interests include social determinants of health in geriatrics, oncology, and rural medicine.
Outside of work and studying, she enjoys mountain biking, skiing, and spending lots of quality time with her cat Sandra.
