Marjorie Cox, Ornithology and Mammalogy Curatorial Assistant
Curatorial Assistant I, Ornithology and Mammalogy

I began my work with CAS Ornithology and Mammalogy as a volunteer in 2016, working in marine mammal stranding response and bone preparation and was subsequently hired on as a curatorial assistant. I have my MSc in marine biology, completing a thesis on northern elephant seal physiology and behavior. My current role at CAS involves bone preparation and marine mammal stranding response, including large whale necropsy.

Rosielyn (Rose) De Guzman
Curatorial Assistant, Botany, and Research Assistant, Geology

I came to the Academy as a volunteer in 2016 in the Geology Department. Now, I split my time working as a Research Assistant for Geology and a Curatorial Assistant in Botany. Some of my duties include collections care, data cleaning, digitization, loan processing, volunteer management, and assisting visiting researchers. I have a B.S. from UC Davis in Wildlife, Fish and Conservation Biology with a minor in Environmental Toxicology. Recently, I graduated from San Jose State University's Master of Library and Information Science program.

Jack Dumbacher
Curator of Birds and Mammals
Evolutionary Biology, Birds and Mammals

I am interested in ecology and evolution, and most of my work has focused on birds and more recently mammals.  Our department of birds and mammals conducts research on local marine mammals, collaborates with US Fish and Wildlife for important surveys of public lands, and we do a variety of research ranging from studying why birds fly into windows in urban settings to how toxic birds acquire and use poisons for defense to using genetics to study relationships among species of animals (and more...)  We currently have students in the lab ranging from high school, Masters students, PhD students

Arachnology

I study the patterns and processes of evolution in scorpions and their fascinating venoms, spiders, and whip spiders. I am particularly interested in the interactions between biota, geology, and climate that have lead to the present-day assemblage of life on Earth. I feel that by understanding the history of life on Earth, we can make better informed decisions for enabling the present-day flora and fauna to continue to adapt and evolve.
