STRUCTURAL BIOLOGY postdoc project

Small Molecule Degraders for Targeting Transcription Factor Drivers in Childhood Cancers


We are recruiting a postdoc for a multidisciplinary, collaborative project that exploits targeted protein degradation (TPD) of pediatric cancer targets using Molecular Glues (MG). TPD is an exciting and rapidly evolving drug discovery paradigm that shows great promise for drugging currently undruggable targets. In this recently funded 5-year project we are developing novel MG approaches to target key transcription factor dependencies in high-risk childhood acute leukemia and medulloblastoma.


We are looking for highly motivated, brilliant minds with curiosity and skills to contribute structural biology insights that shed light on MG interactions with ternary complexes of neosubstrates such as oncogenic transcription factors. Such insights will aid target characterization, MG hit optimization, structure-guided molecular design, all the way to preclinical validation and subsequent clinical translation. These structural biology efforts are integrated into a highly collaborative environment comprised of chemists and pathologists, as well as computational biologists, systems biologists and experimental in vitro/ in vivo biologists that work closely together toward the common goal of improving childhood cancer outcomes.


The project is housed in the Department of Chemical Biology and Therapeutics, and Structural Biology at St. Jude Children’s Research Hospital. It builds on strong investments into a world-class infrastructure in structural and chemical biology. This is an exciting time to join us and build a career while living in an affordable city. This postdoc position is funded for 5 years.
