Contribute to the development and execution of immune-mediated disease models, with opportunities for hands-on in vivo work for candidates with relevant experience or interest
Isolate human and mouse T cell populations using FACS, MACS, and density gradient separation
Develop in vitro assays to assess the therapeutic activity of Treg and conventional T cells
Perform flow cytometry to characterize immune cell populations
Deliver epigenetic reprogramming perturbations to primary T cells using multiple transgenic manipulation methods (e.g., viral vector, lipofection)
