Welcome to the Berkeley Interdisciplinary Research on Climate, Health, and Energy (BIRCHE3) Lab.
Our research focuses on the impacts of energy use - typically at the household level - on air pollution, climate, and health. While progress on providing clean household energy arguably follows development trajectories, there is need to accelerate this transition through innovative policy and dissemination approaches. Our research group builds the evidence base for these transitions based on health, environmental, and economic benefits using the multidisciplinary field of Environmental Health Sciences as the foundation of our work. We use and develop lower-cost sensors to objectively answer questions where evidence is lacking and explore novel techniques to link vulnerable populations with effective interventions.

FEATURED Effects of Cooking with Liquefied Petroleum Gas or Biomass on Stunting in Infants Jan 04, 2024

An intervention strategy starting in pregnancy and aimed at mitigating household air pollution by replacing biomass fuel with LPG for cooking did not reduce the risk of stunting in infants. Published in the New England Journal of Medicine.

FEATURED Liquefied Petroleum Gas or Biomass Cooking and Severe Infant Pneumonia Jan 03, 2024

The incidence of severe pneumonia among infants did not differ significantly between those whose mothers were assigned to cook with LPG stoves and fuel and those whose mothers were assigned to continue cooking with biomass stoves. Published in the New England Journal of Medicine.

FEATURED Heat Exposure among Adult Women in Rural Tamil Nadu, India Dec 05, 2023

Exposure to heat is of particular concern in India, which is one of the world’s hottest countries and also most populous, where relatively little is known about personal heat exposure, particularly in rural areas. Here, we leverage data collected as part of a randomized controlled trial to describe personal temperature exposures of adult women (40−79 years of age) in rural Tamil Nadu.
