The Balsari Lab studies the impact of public health emergencies, disasters, and war on vulnerable populations.
Our team collaborates with populations in distress, humanitarian response agencies, civil society organizations, governments, and international agencies to reduce information asymmetries that threaten to exclude the poor and disadvantaged from decisions that impact their lives.
Leveraging mobile technology, data science, machine learning, and mixed methods, we have built digital decision support tools to advance clinical and population health outcomes in underserved communities globally.
Featured Projects
CrisisReady
Scalable Crisis Readiness Expertise
CrisisReady uses novel data on disaster disruptions and community impacts to develop tools that improve response efficiency and support preparedness efforts. By integrating research, technology, and policy, it aims to enhance resilience and reduce risks during crises.
Heat Risk API
Heat Exposure & Vulnerability Mapping
Turning authoritative climate data into daily, per-community heat exposure metrics for any geography on Earth—so responders can act on local risk, not regional averages.
Climateverse
Climate Change & Human Health
An open-access repository of curated climate datasets that enhances data quality, access, and usability by leveraging LLMs and Generative AI to break down barriers to utilization.
Community HATS
Climate Change & Human Health
Uncovering the impacts of extreme heat, Community HATS supports local communities and governments in India to build effective climate strategies.
Hum Sab Ek
Science Communication
An immersive exhibit built from the powerful stories of 3 million women in India’s Self-Employed Women’s Association, who worked in the informal sector during the COVID-19 pandemic.
What 1,000 Women Workers Can Teach Us About Surviving Extreme Heat
September 19, 2026
In TIME, Dr. Satchit Balsari explains why death counts understate the toll of extreme heat. Through the CommunityHATS study, 1,000 women workers in India are measuring how heat at home and at work affects their health, sleep and wages — and early results show the most vulnerable are already bearing the cost themselves.
