Abstract
I am the Huntington Sheldon Professor of Medical Discovery in the Department of Molecular Biology and Genetics in the School of Medicine at the Johns Hopkins University, where I have been running a lab for 30 years. Our research focusses on the molecular control of embryonic polarity and germline development, with an emphasis on asymmetric cell division and biomolecular condensates. We have uncovered mechanisms that localize proteins and RNAs in the cytoplasm by controlling protein diffusion and RNA condensation. My lab has also characterized a repressive program that launches the germline by inhibiting somatic gene expression in germline progenitors.
