The application cycle for the fall 2022 program is now open.
Pharmacology examines and characterizes the action of drugs in humans and animals. It emphasizes the therapeutic responses of drugs, their mechanisms of action, the fate of drugs in the body, potential adverse reactions, and drug-drug interactions. Physiology considers processes that control and regulate the functioning of systems within an intact organism.
Basic physiological processes underlie all fields in biomedical science. Understanding and exploiting the specific actions of drugs can also furnish a way to probe physiological and biochemical processes in both normal and pathological circumstances. Research in pharmacology and physiology provides challenging and exciting opportunities for graduate study.
The Pharmacology and Physiology (PHPH) program offers graduate courses leading to the MS and the PhD. Both degrees require independent research under the direction of faculty members in the department, who are engaged in highly active research programs involving molecular, cellular and behavioral approaches to experimental pharmacology and physiology in a strongly collaborative environment.

Our Students and Alumni
"My initial interest in the Pharmacology and Physiology Department was partly due to their involvement in the Drug Discovery and Development program. I had always wanted to go into biopharma, and the opportunity to take classes in drug discovery was exciting to me. Additionally, a big draw for me was the work that Dr. Ole Mortensen was doing, and after meeting him I knew I wanted to work in his lab." Read more.

Student Achievements
Dean’s Fellowship for Excellence in Collaborative or Themed Research
Congratulations to Xiaonan Liu, mentored by Dr. Kazuhito Toyooka and Jason Wickman, mentored by Dr. Seena Ajit, winners of the Dean’s Fellowship for Excellence in Collaborative or Themed Research. This fellowship is designed to support PhD-track students with innovative research projects to further develop their research experience.
Dean’s Travel Award
Congratulations to Julia Farnan, winner of the Dean’s Travel Award. The Dean’s Travel Award is meant to partially defray the cost of attending a scientific meeting at which a graduate student is making a presentation, or is related to the student’s graduate study.
Student Travel Award
Congratulations to Simran Gill, who received the Chapter Recognition Student Travel Award from Association for Women in Science (AWIS) to attend the annual meeting of the Society for Neuroscience in San Diego, Calif., in November 2022.
Drexel Emerging Graduate Scholars Conference Award
Rhea Temmermand won 3rd place in the in-person research poster competition of the Drexel Emerging Graduate Scholars Conference. Rhea’s award-winning poster was titled “Development of Glutamate Transporter Modulators as a Novel, Non-Opioid Treatment for Neuropathic Pain.”
Experimental Biology 2022 Award
Jason Wickman won 1st place in the graduate students and post baccalaureate students’ group in the neuropharmacology division at the Experimental Biology 2022 meeting in Philadelphia. Jason’s award-winning poster was titled “miR-106b-25 Dysregulation in Complex Regional Pain Syndrome Contributes to T Cell Dysfunction.”
