Yana Blokhina, Ph.D. (she/her)

Postdoctoral Scholar

Yana joined the lab in April 2019. She moved to the San Francisco Bay Area from Moscow, Russia when she was ten years old. She got her bachelor’s degree in ecology & evolution from UC Santa Barbara, and then joined the genetics graduate program at UC Davis. She completed her PhD working on zebrafish meiosis with Dr. Sean Burgess and Dr. Bruce Draper. Her current research centers around understanding the function and regulation of ribosomal DNA methylation in human aging. In her free time she enjoys cooking, learning Japanese, playing video games, and spending time with family and friends. She also loves cats, wine, and organizing fun activities for the lab.

Following the completion of their internship in the Buchwalter Lab, Charlie stayed with the lab to continue to investigate the role of the nuclear lamina in shaping gene expression during differentiation and its influence on early embryonic development.


Medha Somayaji

undergraduate, UC Berkeley

Medha joined us as an intern in the 2019 QB3 summer internship program when she was a rising senior at UC Berkeley. In collaboration with Shalin Mehta at the CZ Biohub, Medha applied new imaging tools to the nucleolus.
John Hasper, M.S.

Staff Research Associate II

John was our lab manager from 2018-2022. Originally from New York state, John received a bachelor’s degree in physics from Saint Bonaventure University in 2011. At the State University of New York at Fredonia, he completed a bachelor’s degree in molecular genetics in 2014 and a master’s degree in biology in 2016. In the Buchwalter lab, he led a project focused on nuclear protein homeostasis.
Emmy Delaney (she/her)

Graduate Rotation Student (Tetrad)


Emmy rotated in the lab during Fall 2021. She attended UC Davis for her B.S. where she studied Biochemistry and Molecular Biology and did undergraduate research in Dr. Jodi Nunnari’s Lab. After graduating, she did her Fulbright Fellowship in Dr. Thomas Langer’s Lab at the MPI for Biology of Ageing in Cologne, Germany. When not in lab, you can usually find Emmy hiking, on the hunt for new and delicious flavors of ice cream, or snuggled up with a good book and her cat.
