Sara A. Dabydeen                                             Program Director

Scientist by day, instructor by night and travel enthusiast in her free time. Sarah has been our Program Director since 2017. Sarah has a Bachelors Degree in Microbiology from the University of Miami and a PhD in Virology from Rosalind Franklin University of Medicine and Science. She spent 5 years as a naturalist in the San Diego area with a focus on marine mammals.

“I’ve enjoyed being a part of the growth of the San Diego chapter of ACS. The organization has evolved in response to changing times including the COVID-19 pandemic. We found creative ways to continuously host /provide our monthly publicly available seminar series in a way that was safe and accessible to all. In a time when everyone was advised to stay socially distant, ACS-SD found a way to bring people together through the interest and education of various marine topics.”
