Professional Background:
Marsha DeSmet, Ph.D., is a virologist and educator specializing in host–viral interactions, with a focus on human papillomavirus (HPV) replication and persistence. She teaches immunology and microbiology in the biomedical sciences master’s program.
Dr. DeSmet’s doctoral research at Purdue University examined cancer biology, and during her NIH-funded postdoctoral fellowship at Indiana University School of Medicine, she studied post-translational modifications of the HPV E2 replicative protein. Her current research investigates R-loops in HPV replication and genome maintenance, seeking to understand how viral manipulation of host transcriptional processes contributes to persistence and oncogenesis. She also collaborates on projects involving lysine methylation of HPV proteins, host kinase signaling, and development of mouse models for viral oncogenesis.
Courses Taught:
BMS 545: Immunology
BMS 540: Medical Microbiology
Areas of Teaching Expertise:
Immunology, Microbiology, Virology, Cancer Biology
Teaching Philosophy:
Dr. DeSmet emphasizes critical thinking and data-driven inquiry. She uses case-based discussions and problem-solving exercises to connect research findings with clinical applications, helping students evaluate evidence and apply scientific reasoning to complex biomedical questions. Her goal is to prepare students to think like scientists and clinicians, capable of using evidence-based approaches in academic and professional practice.
Research Interests:
Molecular virology, HPV replication and persistence, viral oncogenesis, post-translational modifications of viral proteins, R-loop biology.
