Jeni Janci, PhD

Program Director

Jeni began her life science career in the start-up biotech industry before earning her Ph.D. at University of California, Berkeley in Mike Levine’s laboratory. Her thesis was focused on gene regulatory networks of heart development in the primitive chordate, Ciona intestinalis. Directly after her graduate career, she re-entered the life science industry, where at Entelos she provided Quantitative Systems Pharmacology (QSP) Modeling and Simulation services to assist Research & Development for international pharmaceutical companies and other life science applications. Through consulting projects, she applied large-scale, mechanistic systems models to make critical decisions in various stages of the drug discovery and development lifecycle. She was also one of the architects of the novel Hypertension, Renal Failure, and Heart Failure PhysioLab model. Jeni then expanded her work globally on the PhysioLab platforms via training programs and consulting services. 

Jeni is excited to help advance UCSF’s world-class research to positively impact people’s health and lives. As the newly hired Program Director, Jeni will manage the diagnostics, digital health and bio-tools projects for the Catalyst Program.
