Global Parasitology Seminar Series
IIZD sponsors the Global Parasitology Seminar Series, which 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 EST. Check back soon for the Fall 2025 – Spring 2026 schedule.
Email Nicole Hurd to be added to the announcement list.

Symposia
IIZD hosts an annual symposium that brings together scientists, clinicians, veterinarians, and public health experts to exchange ideas on the emergence, spread, and control of infectious and zoonotic diseases.
The 2025 IIZD Symposium
Robert R. Marshak Public Lecture
Keynote speaker Peter Hotez, MD, PhD, of Baylor College of Medicine, delivered the Marshak Public Lecture on March 19th. His talk, Vaccines and Immunizations in a Time of Global Boiling and Anti-Science, set the stage for the symposium.
The lecture was moderated by Michael Mann, PhD, Penn’s Vice Provost for Climate Science, Policy, and Action. Mann and Hotez are co-authors of Science Under Siege, a forthcoming book scheduled for release in fall 2025.
The public lecture was co-hosted by Penn’s Annenberg Public Policy Center.

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 and comfortable space. P-RIP serves to provide 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.
The P-RIP series is held monthly on Wednesdays at 4PM in Hill 301 and features two presenters.
