We are inteterested in the dynamic regulation of chromatin in stem cells and differentiation (e.g. Kumar et. al., Cell Reports, 2019; Navarro et. al., Nat Comms, 2020; Kumar et. al., Nat Cell Bio, 2 022, Weigert etl. al. Nat Cell Bio, 2023). We will further develop various genome-wide profiling methods (Kumar et. al., Nature Protocols, 2024, including single cell methods (Lyu et. al., manuscript in preparation), and expand a number of collaborations studying the role of epigenetic modifications and nuclear organization on the regulation of pluripotency, lineage commitment and cancer. We have also have various proteomics projects (Schlesinger et.al, iScience, in Press) for which we acquired an Exploris 120.
