Postdoctoral Research Associate - Chemical Biology & Therape

at St. Jude Children's Research Hospital in Memphis, Tennessee, United States

Job Description

Postdoc project in dynamic structural biology:

Exploiting Water Network Perturbations in Protein Binding Sites

We are recruiting a postdoc for a structural biology project that investigates the role of water networks at protein ligand interfaces with a view towards ligand discovery. The position is available immediately and NIH funded for 4 years.

We are looking for highly motivated candidates with curiosity and skills to reveal hidden factors that contribute to protein-ligand binding and leverage this information for ligand discovery. As this project integrates experimental and computational data it will require both a solid background in structural biology and significant computational skills for custom data analysis and automation. Despite the focus on computational structural biology, we will consider exceptional candidates with a suitable experimental background and a strong interest in protein dynamics, ligands and water.

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. You will be embedded into a dynamic lab that has strong expertise in modulating protein conformational ensembles with ligands and temperature (see references below). This is an exciting time to join us and build a career while living in an affordable city.

Please direct your questions and application package including a cover letter, current CV, and 3 letters of reference to: Dr. Marcus Fischer (marcus.fischer@stjude.org).
