Assistant Professor, Global Health - Boston University School of Public Health


I am an infectious disease epidemiologist and veterinarian working at the intersection of global health, One Health, vaccine epidemiology, and Bayesian statistics. My research integrates veterinary medicine, epidemiological methods, mathematical modeling, and Bayesian statistics to tackle issues in infectious disease epidemiology, with two major foci: 1) One Health with climate change and 2) vaccine epidemiology. The overall objective that guides my One Health research is to propose climate-resilient measures to control zoonotic pathogens based on a better understanding of the transmission dynamics among/between humans, animals, the environment, and climate factors in resource-limited settings. For vaccine epidemiology, I aim to inform vaccine policy by developing novel analytic methods for intervention evaluation, especially in resource-limited settings where public health data often have various challenges that make it difficult to draw reliable conclusions. Through my research projects, I have had the privilege of working with local, state, federal, and international organizations as well as =30 countries in my career.

I received my Doctor of Veterinary Medicine (DVM) at the University of Tokyo, Japan, in 2012, Master of Public Health (MPH) in Epidemiology at Emory University, Atlanta, GA in 2014, and PhD in Epidemiology of Microbial Diseases at Yale University, New Haven, CT in 2020.
