Alexandra K. Heaney

I am an Assistant Professor in the Herbert Wertheim School of Public Health at UC San Diego and Associate Director of the MPH Program, where I lead the CARE Research Group.

My research combines environmental epidemiology with causal inference and predictive modeling to understand how climate variability drives human disease — and to build early-warning systems and operational guidance for health departments and clinicians. My work spans the environmental epidemiology of climate-sensitive fungal pathogens; mineral dust and extreme heat; climate and active transport; and the hydrometeorological drivers of diarrheal disease.

Teaching and mentoring are central to how I work. I am committed to training the next generation of scientists to protect human health from climate change and other environmental hazards — you can read more using the sections at left.
