Bethsaida Cardona
Research Assistant

Bethsaida Cardona joined Silent Spring Institute as a Research Assistant in the summer of 2019. Her research focuses on toxic chemicals in consumer products and their impact on human health, including breast cancer risk. She is currently working on a project funded by the NIEHS to identify potential chemicals that target the endocrine system and which may elevate progesterone and estradiol levels. She is also involved in Taking Stock, a project aimed at exploring the types of household consumer products women in California use and how these may contribute to disparities in health.  

Prior to Silent Spring, Cardona studied integrative biology and psychology at Harvard University where she earned her bachelor’s degree. As an undergraduate, Cardona was an advocate for Health Leads at the Boston Medical Center, a healthcare organization with the goal of bringing awareness to and addressing social and economic barriers to health. Cardona also interned at Harvard’s Office for Sustainability, assisting with various projects relating to nutrition, wellness, and sustainability on campus.

Cardona is excited to contribute to the interdisciplinary research conducted at Silent Spring. When not engrossed in a book, Cardona enjoys being active, playing board games and having meals with friends.
