Rollin Coville, Lead Photographer

Rollin received his Ph.D. degree in Entomology from the University of California at Berkeley in 1978. He recently retired from AT&T where he served as a systems analyst and programmer. For more than 25 years his primary outside interest has been photographing insects and spiders. He also has a strong interest in the biology and behavior of Hymenoptera and has published papers on Trypoxylon wasps and Centris bees.
Amanda Niemela, Project Taxonomist
Amanda graduated from UC Berkeley in the spring of 2023 with a degree in Genetics and Plant Biology from the College of Natural Resources. Amanda joined the UC Berkeley Urban Bee Lab in the fall of 2021 because of her passion for conservation biology, interest in plant-pollinator interactions, and because of her enthusiasm for science advocacy. In her free time, she teaches debate and public speaking to high school students and enjoys exploring nature with her friends and family.

Previous Lab Affiliates
Dr. Robbin Thorp, Project Taxonomist (1933-2019)

Dr. Thorp was Professor Emeritus of Entomology at the University of California, Davis. He retired in 1994 after 30 years of teaching, research, and mentoring graduate students. He continued to conduct research on pollination biology and ecology, systematics, biodiversity and conservation of bees, especially bumble bees. He had special interests in native bees of the vernal pool ecosystem. For more information on life history and pollination by these bees, see: www.vernalpools.org/Thorp/.

Sara Witt, Lab Manager

Sara has a B.S. in Conservation and Resource Studies from the University of California, Berkeley. She is currently pursuing a graduate degree at Cal Poly Pomona. She first worked with the Urban Bee Lab while a student at Berkeley as part of the undergraduate research assistant program, and later as the lab manager. Sara also works as an ecologist for the non-profit organization Grassroots Ecology, which involves volunteers in habitat restoration and community science in parks and along creeks in Santa Clara and San Mateo Counties. She also enjoys volunteering as a docent, leading hikes and assisting with bioblitzes at preserves and parks in the Bay Area.
Marissa Chase, Research Assistant
Marissa graduated from Cal with a degree in Molecular Environmental Biology (Insect Biology concentration) and a minor in Forestry. She hopes to continue researching native bees and the development and shift of their floral preferences spatially and temporally. Marissa enjoys collecting and identifying insects and spiders for her personal collection, backpacking/hiking, learning to play guitar, and eating (mainly Takis)/cooking.
Ivonne Verduzco, Research Assistant
Ivonne has B.A. in Molecular and Cell Biology with an emphasis in Developmental Genetics from the University of California, Berkeley. She joined the lab her freshman year of university and stayed involved throughout her undergraduate career.
