Jason Weckstein is an associate professor in Drexel's BEES department and associate curator in the department of Ornithology at the Academy of Natural Sciences.  Jason obtained his BS degree in Natural Resources from the University of Michigan in 1993, his MS in Zoology from the University of Minnesota and his PhD from Louisiana State University in 2003.  After obtaining his PhD Jason was a postdoctoral fellow at the Illinois Natural History Survey at the University of Illinois Urbana-Champaign and at the Field Museum of Natural History in Chicago, where he stayed on as a staff scientist until joining the BEES faculty.  Jason has over 17 years of experience working in natural history museums and has conducted research on birds and their parasites in the United States, Canada, South Africa, Ghana, Malawi, Nicaragua, and Brazil.  In addition to his teaching, training, and research, Jason's additional interests at the Academy of Natural Sciences include collections building, curation and public outreach.
