B.S. Biology, University of Utah, 2018


Sam received his B.S. in Biology from the University of Utah. In Dr. Shawn Owen’s lab, he engineered and validated a three-piece drug delivery system designed to activate a prodrug upon engagement of an overexpressed biomarker, and developed a split-luciferase fusion peptide as both a reporter and epitope tag. In the early undergraduate years, he worked in the lab of Dr. Colleen Farmer to characterize previously elusive locomotor kinematics in the ribs of two lizard species, drawing evolutionary insights.

Prior to starting graduate studies in Biomedical Sciences at UC San Diego, he worked in antibody screening and discovery at xCella Biosciences (now Ligand Pharmaceuticals) in Menlo Park, CA, where he developed new single cell sequencing workflows to enable annotation of antibody secreting B cells. Now in the Yeo lab, Sam focuses on development of RNA-targeting therapeutics. Outside of research, he enjoys scuba, surfing, reef keeping, and fishing.
