In “Where We Are Now,” a five-episode special series, Madeline Bell speaks with five CHOP researchers about the COVID-19-related work they are leading – and about what gives them hope during this challenging time. With episodes focused on everything from a modeling tool that forecasts the spread of the virus across more than 500 U.S. counties to a unique COVID-19 test developed in the CHOP labs, the series takes listeners on a journey from the beginning of the pandemic to where we are now.
