I was invited to give a talk at University of Pennsylvania, for the School of Veterinary Medicine, Parasitology Seminar Series. What a great institution and collection of scientists who study molecular parasitology and the immune response to these pathogens. My host, Chris Hunter, showed me around Philadelphia and treated me to the best seafood ever. Shout outs to Sunny Shin, Igor Brodsky, David Roos, James Lok, Michael Povelones, De’Broski Herbert, Oriel Sunyer and Boris Striepen who took time to meet with me and share some of their exciting and unpublished work. I had a great time indeed, thank you for the invite.
