Nikkil Sudharsanan is a population health and behavioral scientist focused on preventing cardiovascular diseases in low- and middle-income countries. His research uses behavioral insights from economics and psychology to understand how clinicians and patients make chronic health care decisions. Based on this research, he develops and tests interventions to encourage clinicians to provide better quality cardiovascular care and individuals to seek preventive care and adhere to health recommendations. Nikkil received an MA in Statistics and PhD in Population Studies from the University of Pennsylvania. Before coming to TUM, he was an Alexander von Humboldt Postdoctoral Fellow at the Heidelberg Institute of Global Health and a David E. Bell Postdoctoral Fellow at the Harvard Center for Population and Development Studies.
