Questions

How are RNAs regulated in health and disease? How can RNA be manipulated to control cellular decisions?

Approach

The Zamudio lab uses biological systems and computational techniques to discover how RNAs function to promote healthy cellular behavior and to determine how their dysfunction contributes to human diseases. We fit mechanisms of RNA regulation into global gene expression programs with goals of predicting and altering cellular decisions. This fundamental research advances our understanding of gene regulation and will lead to new therapeutic approaches for disease treatment.

About Jesse

Jesse received his Ph.D. in microbiology studying RNA capping and splicing in pathogenic parasites under the mentorship of Dr. David Campbell and Dr. Nancy Sturm. His postdoctoral studies were performed under the mentorship of Dr. Phil Sharp at the MIT Cancer Center. He joined the UCLA faculty in 2016. His research experience spans RNA biochemistry, enzymology, microbiology, cancer and stem cell biology. Originally from the San Fernando Valley, he is a first-generation college student graduating with a B.S. in Chemistry from UCLA. His research interests include characterizing regulatory RNA and RNA splicing in the gene networks that are critical to maintain healthy cells. If he is not in lab, he is likely outdoors: cooking, gardening, looking for an opportunity to build, fix or play something.

Rafael Sandoval

Graduate Student

BS, ’16, UCSD, San Diego, CA

Rafael is a native of Long Beach, CA and a PhD student in the Molecular Biology Interdepartmental Program. Before UCLA, Rafael received a B.S. in Biochemistry and Cell Biology at the University of California, San Diego and a M.S. in Biology at California State University, Los Angeles where he conducted research in the Hayes lab studying RNA editing in plants. Currently, Rafael is interested in the RNAi machinery’s potential role in regulating the transcription of major satellite ncRNAs from the pericentromere in mESCs. Outside of lab, Rafael enjoys playing video games, playing basketball, visiting Disneyland, hiking, and going to the theaters.

Cori Dilsavor

Cori Dilsavor

Graduate Student

BS, ’22, Ohio State University , Columbus, OH

Cori is from Beavercreek, Ohio and is a PhD student in the Molecular Biology Interdepartmental Program. Before making the big move to Los Angeles, Cori received a B.S. in Molecular Genetics and Microbiology at the Ohio State University. During her time at OSU, she conducted research in the Singh Lab studying Nonsense Mediated mRNA Decay, a eukaryotic gene regulation pathway that functions to degrade mRNAs that contain premature stop codons. Cori is excited to continue her research in RNA biology and to explore novel mechanisms of gene regulation mediated by RNAs. Besides being a cool scientist, Cori enjoys playing basketball, playing her guitar, listening to music, and relaxing at the beach.

Postdoctoral and research positions

Inquiries are welcome from innovative and dedicated researchers. Please send your curriculum vitae, research statement and references to jesse.zamudio #ucla.edu. All complete applications will be considered.

Directions to the lab

We are located in the Biomedical Sciences Research Building (BSRB) on the UCLA campus. BSRB is located directly across from the Lot 2 parking lot. If driving, daily parking permits in Lot 2 may be difficult to find. Parking along a Santa Monica Big Blue Bus line and riding in is a good alternative since Lot 2 is a terminal stop on most routes.

To find us, enter BSRB through either the North or South side double doors and find the central stairway. Take the stairs to the fourth floor. As you reach the fourth floor, my office (450C) will be immediately through the central double doors on the North side. To reach the lab, turn right off the stairs and walk all the way to the end of the corridor to find BSRB 454. If you get lost, feel free to call. The lab phone number is (310) 825-9527 and Jesse's office phone is (310) 825-4176.
