About Aparna

As an applied statistician, Aparna Keshaviah brings advanced analytics and innovative data to clarify urgent questions across multiple public health arenas. Her translational approach to wastewater surveillance uses data integration and dynamic visualization to help officials manage infectious diseases and drug epidemics. She has conducted head-to-head comparisons of the safety and efficacy of breast cancer treatments to help clinicians tailor patient management decisions. And she has analyzed and validated psychiatric symptom profiles to inform the diagnosis and treatment of debilitating mental health conditions. Her work aims to communicate scientific findings to technical audiences, academic research communities, and the general public alike.

Keshaviah’s recent research intersects population health and environmental health. In 2016, she began seminal research into how municipal wastewater testing could improve public health and safety. Her ideas around the real-world potential of wastewater-based epidemiology for policymaking inspired new federal funding to advance the field. She has also directed research on emerging drug policy topics—spanning marijuana legalization, the opioid epidemic, and pharmaceutical drug development and safety. Most recently, with a focus on health equity, Keshaviah is leading environmental justice projects aimed at helping clinicians, patients, and communities recognize and address the adverse health issues associated with climate change and environmental chemicals.

Prior to joining Mathematica, Keshaviah directed clinical research at the Dana-Farber Cancer Institute, the Massachusetts General Hospital’s Department of Psychiatry, and the contract research organization Health Decisions. Her work contributed to the latest version of the Diagnostic and Statistical Manual of Mental Disorders and has been widely published in leading journals such as the New England Journal of Medicine, JAMA Psychiatry, and Environmental Health Perspectives. Keshaviah is a 2006-2007 Fulbright fellow and holds a Master’s degree in biostatistics from the Harvard School of Public Health.
