Jarrid Ronnebaum

Jarrid Ronnebaum, PhD, is a medicinal chemist with experience in drug discovery, parallel synthesis and methodology optimization. He is responsible for synthetic chemistry needs of projects at the Indiana Biosciences Research Institute (IBRI), utilizing a vast array of medicinal and classical organic chemistry techniques. During various stages of the drug discovery process, IBRI labs rely on his generation of a diverse collection of chemotypes ranging from small molecule inhibitors to PROTACs.

Prior to joining the IBRI, Ronnebaum was a postdoctoral researcher in the Lee Lab at St. Jude Children’s Research Hospital, where he developed small binders and subsequent PROTACs for a novel E3 ubiquitin ligase. During his time there, he worked with an interdisciplinary drug discovery team where he was the lead chemist in a hit-to-lead and lead optimization project.

Ronnebaum is a native Hoosier and loves the outdoors. He also enjoys spending his free time with his family and dogs.
