Superpower: Prolific consumption of caffeinated beverages
I graduated from the University of North Carolina Chapel Hill with a Ph.D. in Biochemistry and Biophysics, where I worked with Aziz Sancar to study the molecular basis of circadian rhythmicity. I went to the 'dark side' for my postdoctoral fellowship, training in biophysical techniques including solution NMR spectroscopy at UT Southwestern Medical Center. I worked with Kevin Gardner to identify novel structural regulatory motifs on the hypoxia-inducible transcription factor, HIF, and with Joe Takahashi, to study the related bHLH-PAS transcription factor that drives circadian rhythmicity, CLOCK:BMAL1. In our lab, we strive to address these questions: How do animals measure time and use it to control biology on a daily basis?

Superpower: Surviving graduate school and a postdoc without coffee
I discovered the magic of Structural Biology in graduate school while under the mentorship of Scott Pegan at the University of Georgia. Using X-ray crystallography and biochemical assays, I studied the dynamic molecular landscape of virus-host interactions across divergent viruses and hosts. After graduating from the Department of Pharmaceutical and Biomedical Sciences with my Ph.D. in 2019, I began a postdoctoral appointment in the lab of Rebecca DuBois at UCSC, studying antibody-mediated immunity to viruses. My postdoc projects primarily used X-ray crystallography, Cryo-EM, and other biophysical methods to understand broadly protective antibody responses in the context of next-generation influenza vaccine design. In 2024, I joined the UCSC Biomolecular Cryo-EM Facility, in conjunction with the Partch lab, as a staff scientist to assist facility users with their Cryo-EM data and Structural Biology projects.

Superpower: Being reliably 10 minutes early or 20 minutes late
Hey there! I am a second-year student from San Diego pursuing a B.S. in Neuroscience at UCSC. My dream is to pursue a career in radiation oncology and medicine, but along the way, I've discovered a love for biotechnology and lab work in biochemistry. I joined the Partch lab in 2024 as an undergraduate researcher to work hands-on in research and apply my studies to make a difference in understanding our cellular biology.

​
I graduated from Clarkson University in 2016 with a B.S. in Chemistry and a
minor in Engineering Science, but it was actually a summer research experience at the
Scripps Research Institute in 2015 that piqued my interest in biochemistry and
biophysics. In 2022, I graduated from the Pennsylvania State University with a Ph.D. in
Biochemistry, Microbiology, and Molecular Biology. I performed my graduate studies in
the lab of Scott Showalter, where I learned about the fascinating (un)structural biology
of intrinsically disordered proteins (IDPs). I used NMR spectroscopy, X-ray
crystallography, and a smattering of different biophysical methods to understand the
functional interaction between the intrinsically disordered transcription factor, PDX1, and
its negative regulatory partner, SPOP. Through this project and others in the Showalter
lab, I became excited about how post-translational modifications, such as
phosphorylation, can influence IDP ensemble properties, interactions, and functions. To
this end, I joined the lab of Alex Holehouse at Washington University in St. Louis to train
in molecular simulations of IDPs to complement my experimental biophysics
background. In 2025, I moved to UC Santa Cruz and affiliated with the Partch lab. With
joint mentorship from Drs. Holehouse and Partch, I am leveraging simulations and
biophysical experiments to understand how phosphorylation affects the properties and
functions of critical regulatory IDPs, such as those found in the circadian core clock and
the cell cycle.
