We are delighted to host Ernest Iu from Department of Cell & Systems Biology, University of Toronto for three days at Hopkins. We learned a lot from his wonderful talk “Motility, Mechanics and Microscopes: Regulation of cell migration by Ca2+ signaling” and learned useful techniques about TFM too. It is such a refreshing pleasure as the school slowly reopens. Thank you for traveling to visit us, Ernest! Thank you Prof. Sergey Plotnikov for sponsoring the trip.
