RESEARCH EXPERIENCE
Postdoctoral Fellow
Harvard T.H. Chan School of Public Health
Boston, MA
Department of Epidemiology
2020 - 2022
Department of Social and Behavioral Sciences
2020 - 2022
• Investigated the long-term impacts of the 2011 Great East Japan Earthquake on physical,
mental, and cognitive health of older survivors.
• Integrated causal inference thinking with machine learning techniques to examinecomplex heterogeneous effects of a natural disaster on health of survivors.
• Applied an outcome-wide analytic approach to holistically evaluate the impacts of
exposure to a natural disaster on an array of health and well-being outcomes.
• Applied causal inference methods for time-varying treatments to rigorously examine theimpacts of social determinants of health (e.g., social participation).
• Advisors: Ichiro Kawachi, Ph.D., and Tyler J. VanderWeele, Ph.D.
Harvard University
Cambridge, MA
Human Flourishing Program, Institute for Quantitative Social Science2020 - 2022
• Examined global trends and trajectories of multi-dimensional well-being anddemonstrated that assessing well-being with a single-item measure commonly used inliterature (i.e., Cantril’s ladder life satisfaction) can lead to misguided public healthrecommendations.
• Compared global trends in population averages of well-being with those in inequalities ofwell-being and demonstrated that the trends in two metrics remarkably diverge.
• Applied an outcome-wide analytic approach to holistically evaluated the impacts on anarray of health and well-being outcomes of exposures to home confinement and online
religious service attendance during the stringent lockdown in the UK during the COVID19 pandemic.
• Applied an outcome-wide analytic approach to holistically evaluate the impacts of having
a purpose in life on an array of health and well-being outcomes among Japanese older
adults.
• Examined heterogeneous impacts of having a sense of purpose in life on all-cause
mortality by socioeconomic status, gender, and race/ethnicity among in the US adult
population.
• Advisor: Tyler J. VanderWeele, Ph.D.
Graduate Researcher
Positive psychology and healthy aging
Harvard T.H. Chan School of Public Health
Boston, MA
Department of Social and Behavioral Sciences
2018 - 2020
• Investigated how positive psychological factors (e.g., optimism and purpose in life) arelinked to health behaviors and biomarkers of physical health later in life.
• Performed statistical analyses of a nationally representative cohort study of the U.S.
population (Health and Retirement Study) and prepared multiple manuscripts for peerreviewed journals.

affected by the disaster.
• Designed questionnaires for local citizens based on qualitative needs interviews.

based on the study’s results, including the high prevalence of ill-health and risk factors
among residents in temporary housing.
