Associate Database Analyst
Sydney Swanson

Born and raised in San Diego, Sydney wanted a college as close to the beach as possible and attended the University of California, Los Angeles. At UCLA, she received her B.S. in psychobiology with a focus in conservation biology and was involved with numerous on and off campus organizations. During her academic career, she worked as a research assistant in both the Ecology and Evolutionary Biology Research Lab and the Ronald Reagan UCLA Medical Center. 

 

After graduating, Sydney moved to Washington, D.C, and become an official East Coaster. She is extremely passionate about both human health and the environment, and was drawn to EWG because of its mission to encourage people to live healthier lives in a healthier environment. Sydney is stoked to be a part of EWG’s research team and assist on its consumer guides and databases. When not at work, you can find her spending time outdoors, soaking up all the sun she can before hibernating for the non-California winter. Sydney is a fan of scuba diving, collecting vinyl records, binge watching Harry Potter, and obsessing over all animals, especially llamas.

Toxicologist
Alexis Temkin, Ph.D.

Originally from Chappaqua, N.Y., Alexis recently moved to Washington, D.C., to join the investigative science team at Environmental Working Group. She earned her bachelor’s degree in biological sciences from Connecticut College in 2010. Alexis began her research career at Columbia University Medical Center, working as a lab technician studying the molecular mechanisms responsible for environmental influence on gene regulation. She then moved to beautiful Charleston, S.C., to attend the Medical University of South Carolina, where she earned a Ph.D. in marine biomedicine and environmental sciences. She studied how exposure to environmental chemicals during development can influence adult disease, specifically obesity and metabolic syndrome. In her spare time, you can probably find Lexi in a yoga studio, exploring the closest outdoor park, attending a dance performance or cooking vegetables.

Social Media Manager
Isang Udokwere

Isang is a D.C.-area native with a diverse creative background. After spending some time in New York working in the music industry, he returned to the Washington area to work on social media for BlackVoices.com, then ventured on to some notable brand strategy firms and “Silicon Hill” start-ups. He is a firm believer in the idea that the world is having a perpetual digital conversation, and that social media is the only way for organizations to participate. When he isn’t creating social media content for EWG, you can likely find Isang at a concert, modern art museum or in a recording studio. 

VP and Editor in Chief
Bill Walker

Bill has more than three decades’ experience as a journalist and activist. He began his career on a small weekly in his home state of Texas and advanced to the Fort Worth Star-Telegram, where he wrote news and features from across the South. He moved to The Denver Post, roaming the vast reaches of the Rocky Mountain West, then to The Sacramento Bee as national and international correspondent.

His travels exposed him to fragile places under assault from industrial development and communities suffering from corporate exploitation. Determined to fight injustice rather than just write about it, he joined the environmental movement as a press officer for Greenpeace. He coordinated news coverage for dozens of the organization's signature direct actions and headed Greenpeace's national media department before becoming communications director for the California League of Conservation Voters.

In 1996 he opened EWG’s California office, building a team that generated headline-making reports on toxic chemicals, pesticides, water subsidies and more. After 12 years as EWG’s Vice President/West Coast, he opened a consulting practice working with The Story of Stuff, The Breast Cancer Fund, Friends of the Earth and many other groups. In 2015 he rejoined EWG, where he works with scientists and researchers to develop, write and edit reports.  

Bill lives in Berkeley and is raising three teenagers to question authority except when he tells them to clean their rooms.
