Julie Schrey ’21 performed gel electrophoresis following PCR to examine whether a viral gene was present in a recombinant virus that was constructed in the lab.

I was born and raised in Erie, PA. After high school, I attended Bucknell University and obtained a bachelor of science degree as a Cell Biology and Biochemistry major. After college, I joined the Cell and Molecular Biology graduate group at the University of Pennsylvania to work on earning a doctorate. My work in graduate school focused on the characterization of CD8+ T-cell responses in various types of HIV-infected patients. While this area of research was quite interesting, I realized it would be extremely difficult to continue in the field of HIV immunology at a small college or university, which was my ultimate goal. Consequently, I sought a lab for my post-doctoral training that made use of in vitro systems and mouse models to investigate viral immunology. I chose to join the lab of Laurence Eisenlohr, VMD, PhD, an expert in the study of antigen processing and T-cell responses in the context of viral infections. It was in this setting that I learned about ectromelia virus (ECTV), a natural pathogen of mice. ECTV is safe to work with and an ideal virus to study with undergraduate student collaborators. Like all poxviruses, ECTV encodes numerous proteins that modulate host processes and the immune system. The study of host-pathogen interactions, especially immune evasion mechanisms, has become a major focus of my research.

I currently call Pottstown, PA home. I have two incredible children ages 3 and 5 that keep me very busy. In my spare time (ha!), I enjoy hiking, gardening, and visiting microbreweries.

Ectromelia virus expressing GFP (green fluorescent protein) was used to identify virus-infected cells growing in culture. This image shows a cluster of infected cells, which is referred to as a “plaque”.
