Meet Tracking California's new Executive Director, Dr. Shubhayu Saha

We're excited to welcome Dr. Shubhayu Saha as our new Executive Director!


Shubhayu brings over 15 years of experience addressing climate-related health risks, especially in communities most vulnerable to environmental hazards.


Shubhayu has worked at the U.S. Department of Health and Human Services, including roles at the CDC's Climate and Health Program and at the Office of Climate Change and Health Equity.

His work has spanned interdisciplinary research on the impacts of climate hazards such as temperature and weather extremes, air pollution, drought, and flooding; developing data tools for emergency response, environmental monitoring, surveillance, and planning; and creating resilience strategies for use by public health agencies and communities.


Shubhayu has also served as an author and committee member for the last three U.S. National Climate assessments and is a founding member of the Global Heat Health Information Network.


As Tracking California's new Executive Director, Shubhayu is committed to amplifying the implementation of community-engaged climate resilience programs and making environmental health data accessible and actionable through partnerships. The program will continue to build on the trust among community partners and recognition of scientific integrity it has earned over the years.


On a personal note, you will never hear Shubhayu complain about ‘too much’ soccer, music and chocolate.


If you have questions or would like to set up a meeting with Shubhayu, please email us at info@trackingcalifornia.org

Updates to our Data Explorer

Nuestro explorador de datos, ahora disponible en español - Our Data Explorer, now available in Spanish

Last year, we launched our Data Explorer - a tool that lets you search for environmental health topics and data through maps, charts, trends, and tables. 


Now, it's also available in Spanish! If your browser is set to the Spanish, it will appear automatically when you open the Data Explorer tab. If not, you can switch languages using the toggle button (EN/ES) at the bottom of the Data Explorer.

More recent data is also available

We have updated the environmental and health data in our Data Explorer. You can now find more recent years of data for air quality, asthma, birth defects, childhood lead poisoning, chronic obstructive pulmonary disease (COPD), heat-related illness, and heart attacks.

Poster: Breaking the Monolith - Understanding Asthma Burden in Asian American, Native Hawaiian, and Pacific Islander Californians

Scarlet Sands-Bliss, Research Data Analyst at Tracking CA, presented at the California Department of Public Health's Epidemiology Forum


Grouping Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations together can hide important differences. For example, Native Hawaiians and Pacific Islanders are over 4x more likely to visit the emergency room for asthma than White Californians, while Asian Americans (grouped) have a 15% lower rate on average.
