Guochang (Leonard) is a stem cell biologist whose work bridges developmental biology and applied innovation to generate midbrain dopaminergic (mDA) neurons from human iPSCs. During his PhD at Karolinska Institutet, he applied single-cell multiomic profiling to characterize mDA neurons, developed robust and reproducible differentiation protocols, and led proof-of-concept transplantation studies that restored motor function in Parkinsonian animal models, advancing both Parkinson’s disease modeling and cell replacement therapy development.

Leonard’s scientific journey began with a Bachelor of Medicine from Fudan University, where his medical training sparked a lasting interest in regenerative medicine. He further expanded his expertise through cross-disciplinary projects at the intersection of biology, technology, and translational research during his time at UCLA and USC. His doctoral research was supported by the Marie Skłodowska-Curie Fellowship, focusing on the molecular phenotyping of mDA neurons for disease modeling and therapeutic applications.

At Scitaris, Leonard leverages his scientific depth and analytical acumen to advise on biopharmaceutical strategy — evaluating preclinical and clinical evidence, assessing therapeutic program feasibility, and delivering data-driven insights that inform strategic decision-making for biotechnology and pharmaceutical clients.
