Victoria Glynn

Victoria earned her B.Sc. in Environmental Sciences from the University of California, Berkeley, minoring in Science and Math Education (CalTeach). As an undergraduate, she worked with Dr. Jamie Cate (UC Berkeley) using CRISPR-Cas9 to: genetically engineer yeast for specialized fatty-acid production, and reduce wheat and rice’s susceptibility to bacterial and fungal pathogens. Her honors thesis under Dr. Claire Kremen (UC Berkeley) studied how passerine and near-passerine birds in California’s Central Coast are impacted by agricultural land use change; this was achieved by linking haematological metrics and aerial imagery via mixed-effects modeling. Victoria is also passionate about STEM outreach. With the CalTeach program she designed culturally-relevant science curriculum and taught over 200 hours in K-12 classrooms in the East Bay. For her Ph.D. she is interested in exploring coral’s molecular responses to climate change. Victoria is part of the NEO-STRI Program and is being co-advised by Dr. David Kline (STRI).
