Global Parasitology Seminar Series
The Global Parasitology Seminar Series brings together speakers and audiences from around the world to share the latest research in parasitology, immunology, and molecular biology.
Seminars are open to all and are held in a hybrid format on select Mondays at 12:00 PM ET. The series will resume in Fall 2026. Email Nicole Hurd to be added to the announcement list.

Parasitology Research in Progress (P-RIP) Series
Parasitology Research in Progress (P-RIP) is a parasite biology forum where students, postdocs, and staff present their research and receive feedback in an informal, comfortable setting.
P-RIP provides an opportunity for trainees to present ongoing work in a relaxed atmosphere and to strengthen connections in the parasitology community across campus and the greater Philadelphia area.
P-RIPs are held monthly on Wednesdays at 4:00 PM in Hill 301 and feature two presenters. The series will resume in Fall 2026.
