Congratulations to undergraduate NSF REU researcher Ryan Fergusson for receiving a travel award to attend the national annual meeting of the Society for the Study of Evolution in Austin, TX this June, where he will present a poster on research delineating the remarkable diversity of ascidians in the Philippines, in collaboration with Master's alumna Darragh Clancy, and summer 2015 volunteer Kelly Donahoe.
Congratulations to Anastasia Ennis for her travel award from CSU COAST to attend the Mammalogy society meeting in Minneapolis this June to present her work on immune system variation in SF Bay endangered marsh mice.
Lots of recent lab outreach activities including: talks at the Children's Day School of San Francisco (with assistance from lab volunteers Samantha Prado and Mai Ly Cohen Barschall), the Villa Marin senior community in San Rafael (with assistance from SFSU graduate seminar participants in BIOL 862, Molecular Ecology and Evolution), and a 6th grade field trip to Duxbury Reef with 10 classes from Oak Grove Middle School in Concord, CA, organized by former Cohen lab STAR intern Zachary Sturbaum. Volunteers generously assisting with the field trip included STAR mentors/instructors Dr. Larry Horvath of SFSU Education and Analise Heid, members of the Cal Academy/Marin MPA monitoring network, entering graduate student Noah Jaffe, and more! (April 2016)
