Kevin Tharp studies the interplay between mitochondrial metabolism and the physical properties of the tumor microenvironment, using genetically engineered mouse models and bioengineered human tumor models to define the mitochondrial programming unique to cancer cells in the tumor microenvironment.
His goal is to develop new therapies that block the metabolic adaptations that cancer cells use to metastasize, a major cause of cancer-associated mortality.
“I study how cells make decisions about their metabolic programming, which I expect will enable us to develop new therapeutics against metastatic tumor cells.”
Tharp previously worked as a postdoctoral scholar in the Center for Bioengineering & Tissue Regeneration at UCSF Health.
He completed his PhD in metabolic biology at UC Berkeley and his Bachelor of Science degree in biochemistry and molecular biology at UC Santa Cruz, where he graduated with honors and the Dean’s Award in Chemistry.
He has received meritorious funding awards from the Sandler Foundation and the National Institutes of Health/National Cancer Institute for his postdoctoral research.

After a successful teaching career at the University of Michigan I have had the privilege to “reboot” my research career at Sanford Burnham Prebys where I have had the opportunity to develop novel methodologies to understand cardiomyopathy. I have also had the opportunity to work with NASA scientists to do experiments on the International Space Station.

The Ocorr Lab is investigating the cellular and molecular basis of adult heart function and cardiomyopathies using the genetic model system Drosophila.
We use functional, electrophysiological, biochemical and immunohistochemical techniques that allow us to examine the roles of genes and gene products in cardiac channelopathies and stress-related cardiomyopathies.
Our lab pioneered the development of a novel methodology (Semi-automatic Optical Heartbeat Analysis, SOHA) that permits the quantification of heartbeat parameters in model systems with small hearts.
Using this system we have identified several ion channels in the fly heart that play prominent roles in repolarization of the human heart and cause arrhythmia in both the fly and in humans when mutated. We also have developed a number of other disease models including a diabetic-like cardiomyopathy induced by high sugar diet and hypoxia-induced cardiomyopathy.
Recently we have begun collaborations with NASA (by winning a Space Florida International Space Station Research Competition). We are using the fly to uncover the molecular/cellular basis for cardiac and muscle atrophy in astronauts exposed to extended periods of microgravity despite extensive exercise regimes aboard the ISS. Our flies were launched aboard SpaceX 3 for a month-long exposure to micro-gravity.
Karen Ocorr’s Research Report
My lab is working to understand the cellular and molecular basis of heart disease. One project is focused on the genetic basis of Atrial Fibrillation. This project is a collaborative one with the lab of Alexandre Colas. We are combining two model systems, the fly in my lab and human induced cardiomyocytes in his lab, to identify AFib genes that have been implicated from patient studies. Another project focuses on the role of metabolism in cardiomyopathies. This is because obesity and metabolic syndrome are linked to an increased risk of heart disease. We are studying the role of a key metabolic signaling molecule in hypertrophic cardiomyopathy. A separate effort is focused on the role of gravity in heart function. These studies will provide important information for future habitants of colonies on the moon and Mars. But they are also relevant to patients who are bedridden and to patients with muscle wasting (sarcopenia).
