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: I’m always hungry.

I am an engineer in molecular biotechnology from the Universidad de Chile, where I studied antibiotic-resistant bacteria in natural environments. I am currently doing my PhD at the Pontificia Universidad Católica de Chile, studying the molecular mechanism of the circadian clock of the fungus Neurospora crassa, in particular, the post-translational regulation of the enzyme casein kinase 1 (CK1). That line of research led me to Partch Lab, where I was welcomed as an intern to continue unraveling the mysteries 
behind CK1 regulation.

Superpower: I have an encyclopedic knowledge of 'The Hitchhiker's Guide to the Galaxy'


I graduated from St. Catharine's College, Cambridge in 2013 with a BA in Natural Sciences (Pharmacology). I subsequently completed my PhD - entitled 'Metabolic regulation of circadian timekeeping' - at the MRC Laboratory of Molecular Biology, also in Cambridge, under the supervision of Dr. John O'Neill. Having decided that there were far too many interesting questions in circadian biology to stop quite yet, I joined the Partch Lab in 2018.

Superpower: Keeping a straight face and being unintentionally sarcastic


I graduated from the University of California, Santa Cruz with a B.S. in Biochemistry and Molecular Biology. In pursuit of a graduate degree, I have joined the Partch lab as a postbac, helping study PAS domains of core circadian clock proteins.

Superpower: Public speaking and using my abilities to teach students science! 

Hi there! I graduated with my B.S. in Biochemistry from California State University, Fullerton. I’m also a first-generation college student and the first in my family to pursue a Ph.D.

Superpower: Making it all look so easy...

I graduated from San Jose State University with a B.S. in Biochemistry and a minor in Biology. In 2019, I joined the Partch lab to study the similarities between different biological time-keeping mechanisms.
