Tricia Humphreys

Tricia Humphreys is a Professor of Biology at Allegheny College, where she holds the Clarence and Helena Mumaw Schwartz Professorship in Biology and Life Sciences. She is based in Steffee Hall, Room B211, and serves as the Biochemistry Program Director and a faculty member in the Global Health Studies program. She is also an advisor for the Allegheny College Equestrian Club and Aikido Club, and serves on the Health Professions Committee.

Education:

• B.A. in Biology, Thomas More College
• Ph.D. in Microbiology, Miami University
• Post-Doctoral Fellow, Indiana University School of Medicine (Infectious Diseases)

Her research centers on the human pathogen Haemophilus ducreyi, the causative agent of chancroid, a sexually transmitted infection with implications for HIV transmission. Her lab investigates evolutionary relationships among bacterial isolates, antibiotic susceptibility, and the potential use of essential oils as treatment. A key focus is understanding the biological basis for the observed male bias in chancroid incidence and exploring non-sexual transmission routes, particularly in pediatric limb ulcers in Pacific Island nations. Techniques include DNA sequencing, bacteriology, bioinformatics, and biochemical assays.

Although no recent publications are listed in the provided text, her research spans microbiology, infectious disease dynamics, and global health, with emphasis on pathogenesis and public health implications in resource-limited settings.

Scientific Awards and Honors:

• Clarence and Helena Mumaw Schwartz Professorship in Biology and Life Sciences

Dr. Humphreys mentors undergraduate researchers and integrates students into all aspects of her research program. She is actively involved in academic service, including program leadership and student advising. She also contributes to campus life by advising two student clubs, demonstrating a strong commitment to student development beyond the classroom.

Labs and Research Groups:
She leads the Chancroid Lab, which is active in microbiological and molecular research on Haemophilus ducreyi. The lab engages students in hands-on scientific inquiry and maintains a presence on Instagram (@chancroidlab).
