Jonathan Winger, PhD

Co-Founder and VP Process Development & New Product Introduction

Jonathan Winger is co-inventor of the H-NOX technology from which OMX therapeutics are derived, and has 20+ years of experience with production and study of H-NOX and other proteins. At Omniox, he oversees the design, production, and characterization of protein variants with different kinetic and stability profiles, and manages process and analytical development for candidate OMX therapeutics. Prior to Omniox, Jonathan was an American Heart Association Postdoctoral Fellow at the University of California, Berkeley, where he used structural biology techniques including X-ray crystallography, small-angle X-ray scattering, and NMR to study H-NOX proteins, kinases, and other proteins. He obtained his PhD in Medicinal Chemistry at the University of Michigan, where he used spectroscopy and enzymology to study the role of soluble guanylate cyclase (sGC), an H-NOX-containing protein, in nitric oxide signaling pathways. Insights gained from this work contributed to the conception and founding of Omniox. Jonathan has published numerous research papers and abstracts, co-authored several book chapters, and is an inventor on multiple patents.
