She went to Middlebury for her undergraduate education before coming to the Bay Area. Outside of lab, Kate is an avid bike rider and enjoys participating in scientific outreach programs and Twitter.
Anna Grigsby-Brown (she/her)
GRADUATE STUDENT, NEUROSCIENCE
Anna is a UCSF Neuroscience graduate student screening for genetic modifiers of ASD risk genes in Drosophila. She received her B.S. in neurobiology from Georgetown University. She worked at the National Institute of Neurological Disorders and Stroke (NINDS) as a postbaccalaureate fellow, studying lipid metabolism and transport in the larval brain. Outside of the lab, she enjoys exercising, participating in sports leagues, and spending time with her twin sister and their cats.
James Schmidt (he/him)
RESEARCH ASSISTANT
James graduated in 2023 with a B.A. in Neuroscience from Pomona College, where he played baseball and focused his on-campus research towards chondroitin sulfate proteoglycans in Drosophila. He recently returned home to the Bay Area to expand his model organism expertise to Xenopus. Outside of the lab he enjoys spending as much time outdoors with his dogs as humanly possible.
Elina Kostyanovskaya (she/her)
GRADUATE STUDENT, DEVELOPMENTAL & STEM CELL BIOLOGY
Elina is a PhD graduate student studying the role of SYNGAP1 in development using Xenopus as a model organism. She received her B.S. in Biology with a specialization in genetics from the University of Chicago. She is passionate about inclusive teaching and mentorship, with a focus on disability justice. Outside of lab, she enjoys Olympic weightlifting and attempting small scale DIY furniture projects.
Ethel Bader (she/her)
LAB MANAGER
Ethel has a B.S. in Electronics and Communications Engineering from the Philippines. Through the Bridge to Biotech Program offered by City College of San Francisco, she earned a Laboratory Technician Certificate. Prior to working with the Willsey Lab, she was an SRA at Dr. Tecott’s Laboratory managing his animal colony and helped design and execute several mouse behavior experiments using standard behavioral assays and a novel quantitative approach to home cage behavioral monitoring. She now has experience in human cell culture and her work in the lab uses these cells to translate results from the frogs to human cells.
Catherine Nguyen (she/her)
RESEARCH ASSISTANT
Catherine graduated from UC San Diego in June 2023 with a B.S. in Chemistry. She assists with different research projects in the lab by performing molecular biology techniques. She hopes to continue learning more about the genes associated with ASD and incorporate her love for chemistry and biology. Outside of lab, she enjoys reading and traveling whenever she gets the chance.
Christina Roca (she/her)
GRADUATE STUDENT, NEUROSCIENCE
Christina is a Neuroscience graduate student at UCSF studying ciliogenesis and neurodevelopment in Xenopus, specifically the role of cilia in pediatric neurodevelopmental disorders. She earned her B.S. in Behavioral Neuroscience at Florida International University in Miami, FL. Christina enjoys participating in educational outreach programs to teach students about science. Outside of the lab, Christina loves to hike around the Bay Area.
Juan Arbelaez (he/him)
RESEARCH ASSISTANT
Juan received his B.S. in Biochemistry and Cell Biology from UC San Diego. With extensive experience working with stem cells, he lends his guidance, leadership, and wet-lab management skills to the Willsey Lab as well as the State Lab. Currently, Juan is working on several projects involving iPSCs and CRISPR-Cas9.
Ashley Clement (she/her)
ADMINISTRATIVE OFFICER
Ashley helps the lab with all things admin! She has been with the Willsey-State group since 2018 and loves to help find solutions to any and all problems. Ashley attended Clark University in Worcester, Massachusetts where she studied Sociology and Gender Studies. She lives outside of Boston with her husband and son.
Delfina González, PhD (she/her)
POSTDOCTORAL SCHOLAR
Delfina is a post-doctoral researcher studying a potential role for SHANK3 connecting cilia and neuro-developmental disorders, such as Phelan-McDermid syndrome. She earned her PhD in genetics from Yale University in 2024 where she did research on SMAD nuclear transport using yeast, frogs, and human cell lines. She graduated with a BA in Biology from Pomona College in 2017. In addition to science, Delfina is passionate about equitable teaching, mentorship, and educational development to support students from underserved populations. Outside of lab, she loves dancing, running, and yoga.
Angeline Chemel (she/her)
GRADUATE STUDENT, DEVELOPMENTAL & STEM CELL BIOLOGY
Angeline is a DSCB gradute student studying KCNT1 epilepsy using Xenopus as a model organism. She graduated from San Francisco State University with her B.S. and M.S. in Cell and Molecular biology. She enjoys mentoring students as well as spending time with her two cats and running in Golden Gate Park.
Nolan Wong (he/him)
RESEARCH ASSISTANT
Nolan graduated from UC Davis and is a research assistant in the laboratory, taking care of all frog-related matters. He has a passion for veterinary work and animal pathogens.
