  • Overview

    The Fischer lab is recruiting an Associate Scientist for a project that exploits the protein conformational landscape for ligand discovery in pediatric cancer.

    We are looking for applicants with a strong training in molecular biology, protein biochemistry, and structural biology and a keen interest or ideally experience in ligand discovery.


    You will be part of a young, interdisciplinary team that uses structural biology (multi-temperature and high-throughput crystallography) to characterize disease-relevant protein states, computational methods (MD, docking, custom software) to analyze and exploit them, and experiments (biophysical, biochemical, cell-based assays) to test the impact of small molecules on biology and disease. These approaches have relevance for allosteric regulation of proteins and protein-protein interactions.


    The successful candidate has these attributes:

    1) Must be able to conduct independent research in molecular biology and protein biochemistry, including cloning and protein purification, that enable structural studies.

    2) Demonstrated experience in protein crystallography.

    3) Familiarity with large-scale/ high-throughput approaches, automation, liquid handling, biophysical assays or computational approaches is a plus.

    4) Proficiency in e.g. python or shell scripting will facilitate scaling up data analysis.

    5) Must be eager to learn and implement new techniques from those relevant areas. 


    Besides working on your own projects, you will form a liaison for other lab members and support projects within the lab while maintaining efficient laboratory operations.


    Our group is housed in the Department of Chemical Biology and Therapeutics (https://www.stjude.org/research/departments-divisions/chemical-biology-therapeutics.html), and Structural Biology (https://www.stjude.org/research/departments-divisions/structural-biology.html) at St. Jude Children’s Research Hospital. With ongoing investments into exceptional structural and chemical biology facilities, this is an exciting time to join our lab to do cutting-edge research whilst living in an affordable city.  

    Stable funding for this post is available.



    Minimum Experience

    • A minimum of fifteen (15) years of relevant post-degree work experience is required with a Bachelor's degree, with at least seven (7) years at the Research Lab Specialist level
    • A minimum of fourteen (14) years of relevant post-degree work experience is required with a Master's degree, with at least seven (7) years at the Research Lab Specialist level
    • A minimum of nine (9) years of relevant work experience including post-doctoral and/or technical staff experience is required with Ph.D.

    Minimum Education

    • Bachelor's degree in an appropriate scientific field is required.


    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).
