Over the last six weeks, I have had the unique opportunity to be the Senior Fellow at USC Shoah Foundation - The Institute for Visual History and Education. It’s been an honor for me to be here, especially since I led the Institute between 2000 and 2008. Returning to this remarkable place, having the opportunity to use the Visual History Archive, and working among dear former colleagues and new friends has been simply thrilling.
