Postdoctoral Research Associate on Investigation of Immunotherapies at the Nanoscale

The newly established Ghosh lab focuses on ‘Target Screening and Immunoreceptor Engineering’. We utilize cutting-edge fluorescence imaging modalities, namely single-molecule localization microscopy (SMLM), lattice light-sheet microscopy (LLSM), and expansion microscopy (ExM), to investigate the (a) molecular binding mechanisms and dynamic interactions of therapeutic monoclonal antibodies (mAbs) with target antigens on tumor cell membranes and (b) cell-cell interactions between chimeric antigen receptor (CAR) engineered T cells and tumor cells. The scientific aims and scope of the research group are cross-disciplinary, with strong core expertise in biophysics and cell biology, and a clinical focus on hematological malignancies.

Your Tasks

Our current research efforts are focused on molecular mapping of bispecific antibody-mediated immune synapse architecture, quantitative imaging of receptor clustering, actin organization at the synapse, and understanding the overall molecular binding and cytotoxicity activity mechanisms of therapeutic antibodies. Key targets under investigation are GPRC5D and BCMA. The prospective candidate is expected to design and implement imaging experimental workflows (SMLM and/or LLSM and/or expansion microscopy) with the aim of visualizing the spatial organization of receptors and cytoskeletal proteins at the T cell-tumor cell junctions and how they correlate with the mechanistic success of cytotoxic pathways. Furthermore, we also aim to implement real-time 4D imaging experiments for dynamic visualization of antigen-antibody interactions and antigen internalization.

Your Profile
