Randolph Larsen

Portrait of Randolph Larsen

Randolph (Randy) Larsen is excited by the challenge of studying the biology behind cancers that have been notoriously difficult to treat. He hopes to shed light on how and why these cancers arise so that more precise and effective therapies can be developed.

Larsen earned his bachelor’s degree in biochemistry in 2019 from St. Mary’s College of Maryland (SMCM) in St. Mary’s City. There, he was awarded the Chemistry and Biochemistry Department’s Award for Excellence in Biochemistry, which is given to the most outstanding Biochemistry major in each graduating class. At SMCM, he worked in the lab of Geoffrey Bowers, PhD, studying chemical interactions with mineral surfaces, as well as the role of mineral surfaces in the origin of life.

Larsen currently works in the lab of Mark Hatley, MD, PhD, Oncology, where he researches soft tissue sarcomas with a focus on rhabdomyosarcoma (RMS). He hopes to use model systems such as genetically engineered mice and iPSCs along with techniques such as CRISPR screens and sc-RNA-Seq to study core regulatory circuitry underpinning RMS transformation and tumorigenicity. He earned his master's degree from the St. Jude Graduate School of Biomedical Sciences in May 2021. 

“It is an incredible blessing to be at an institution that has such a powerful mission and outstanding research capabilities,” he says. “I’m excited be part of the next generation of researchers working to cure catastrophic childhood cancers.”
