Jeremy Willsey | UCSF Profiles
Assistant Professor, UCSF School of Medicine

Dr. Jeremy Willsey completed his BSc in Molecular Biology & Biochemistry in 2010 at Simon Fraser University in British Columbia, Canada. In 2014, he completed a Ph.D. in Genetics at Yale University in Matt State’s lab. After a one year postdoc at UCSF, he became an Assistant Professor under Dr. Stanley Prusiner in the Institute for Neurodegenerative Diseases at UCSF, and under Dr. Matthew State in the Department of Psychiatry at UCSF.

Jeremy’s research focuses on two complementary areas. He has played a key role in discovering genes contributing to autism and Tourette disorder and will continue to lead a major effort in characterizing the genetic architecture of Tourette disorder. The second arm of his research aims to use the clues provided by these discoveries, along with emerging data on the molecular landscape of human brain development, to understand key aspects of the underlying biology of these disorders. Together with Dr. State, his group has already used these methods to determine that autism risk genes coalesce in a specific part of the brain-the prefrontal cortex-during fetal development in a particular type of cell, the so-called deep layer cortical projection neurons. These two avenues of research not only provide critical information regarding the etiology of these psychiatric disorders, but promise new insights into developing novel treatment approaches. Along with Dr. State and Dr. Nevan Krogan, he has recently founded the Psychiatric Cell Map Initiative at UCSF (pcmi.ucsf.edu), aimed at elucidating the protein-protein, protein-DNA, and genetic interaction networks underlying psychiatric disorders. Dr. Willsey is also part of the TIC Genetics Executive Steering Committee (tic-genetics.org) and leads the committee for Systems Biology & High Throughput Data Generation.

Postdoctoral Fellows

Nawei Sun –
nawei_croppedDr. Sun has a B.S. in Biotechnology from the Jilin University of China and has recently completed a Ph.D. in Genetics at Rutgers University. With a decade of research experience, ranging from investigations of cancer cell line stability to differentiation of iPSCs, Dr. Sun’s doctoral research has focused on uncovering the genetic etiology and neurobiology of Tourette’s Disorder. Utilizing her expertise in stem cell biology, molecular genetics, and neurobiology, she has performed whole exome sequencing to identify Tourette Disorder associate sequence variants, generated iPSC lines and used transcriptome analysis to identify affected biological pathways, and leveraged this data to uncover possible molecular and cellular phenotypes. In her time at the Willsey Lab, Nawei will continue her cutting-edge research, leading our efforts to utilize iPSCs to better understand ASD and other neurodevelopment disorders.

Irina Epstein –
Irina_croppedDr. Epstein completed her Ph.D. at the Max Planck Institute for Brain Research / Goethe University in Frankfurt, Germany, where she studied RNA-based mechanisms underlying
the regulation of local protein synthesis in the context of synaptic plasticity and learning and memory. Currently, she is a Postdoc with Steven Finkbeiner at the Gladstone Institutes and in the Departments of Physiology and Neurology at UCSF. Irina has a keen interest in the molecular and cellular underpinnings of autism spectrum disorder (ASD) and is collaborating with the Willsey Lab to study the effects of de novo ASD-associated mutations on the structure and function of iPSC-derived neurons using high-throughput robotic microscopy.

PhD Students

Sheng Wang
sheng_croppedSheng has a B.S. in Biological Sciences from China Agricultural University in Beijing, China. He recently concluded postgraduate work at the National Institute of Biological Sciences in Beijing. In his previous research, Sheng worked on projects involving genetic knock-out organisms, construction of a stable cell line with DNA-methylation silenced EGFP and subsequent screening for epigenetic regulators, identification of postzygotic mutations in donor tissues using whole genome sequencing data, and the creation of a next-generation sequencing library using a custom-designed autism-related genes panel. In his time at the Willsey Lab, Sheng will continue to lead cutting-edge research using next-generation sequencing data and systems biological analyses.
