Le Pen Lab
Our lab focuses on innate immunity to RNA viruses. The genomes of humans and other animals harbor genes that have naturally evolved to combat viral infections and promote health. Our goal is to identify these antiviral strategies shaped by nature and uncover their mechanisms of action.

Jérémie Le Pen
Jérémie received his formal training in Genetics and Systems Biology at École Normale Supérieure in Paris, France. He then joined Prof. Eric Miska’s laboratory at the University of Cambridge, UK, as a graduate student, focusing on small RNA biology in C. elegans. His graduate studies coincided with the discovery of the first natural virus in C. elegans, providing him with a unique opportunity to contribute to early research on viral infection and antiviral immunity in nematodes.
In 2017, Jérémie joined virologist Charles Rice’s group at Rockefeller University, NY, as a postdoc. There, he worked on projects combining human genetics and functional genetic screens in cell cultures to better understand how the human innate immune system controls RNA viruses and live-attenuated vaccines. Charles Rice was awarded a Nobel Prize in 2020 but, despite what Jérémie’s mother believes, he had nothing to do with it.
Jérémie started his group in December 2024 at the Harvard T.H. Chan School of Public Health, Department of Immunology and Infectious Diseases. He is now looking for people brave—or perhaps foolish—enough to join him in exploring the antiviral strategies that nature has evolved in animal cells.
Lab Members
Don has a background in molecular biology and HIV genetic evolution, particularly in West Africa. Research projects have recently focused on Zika, Dengue and SARS-CoV-2 viruses. Don is eager to explore new tools and systems targeting how RNA viruses interact with the immune system.
Outside of work Don enjoys the beach, travel and running – and is happy to chat about his two Boston marathons.
Lucas received his BS in Molecular and Cellular Biology at Johns Hopkins University in Baltimore, MD. He is very excited to start identifying new viral host-pathogen interactions and how these mechanisms are conserved across organisms.
Outside the lab Lucas loves going to concerts, performing in local theater, trying new restaurants, and referring to himself in the third person.
Sophie is originally from Boston and spent some time in NYC studying infectious diseases at NYU, combining public health with microbiology. As an undergrad she began researching malaria, but confirmed her true love for virology after studying emerging mosquito-borne viruses in the Kenneth Stapleford lab. She is excited to continue this work in the Harvard virology program and in the Le Pen lab!
Outside of lab, Sophie loves eating her way through the city, climbing up rock walls, and collecting unfinished art projects.
