Mohamed Seleem, PhD

Mohamed Seleem, PhD

Professor of Microbiology, Section Head of Microbiology and Immunology, University Faculty Scholar, Graduate Studies Committee Chair

Dr. Seleem’s research is focused on developing new antimicrobials and on improved delivery of drugs for the treatment of infectious diseases that affect both humans and animals. The group also is developing an early detection and identification of a single bacterium/fungus in a complex environment. This development will shift the paradigm of diagnosis from a time-consuming, cultivation-dependent procedure to a culture-independent, in situ approach. Dr. Seleem is the section head of Microbiology, Immunology, and Molecular Genetics at Purdue Veterinary Medicine. In addition to his research, Dr. Seleem has a longstanding commitment to teaching, training, and mentorship at all levels, including graduate and DVM students, postdoctoral fellows, and junior faculty. Many of whom have gone on to highly successful academic careers in related areas.


Haroon Mohammad

Haroon Mohammad

htmohamm@purdue.edu

Postdoctoral Research Associate

A life-long Boilermaker, Haroon completed dual Bachelor of Science degrees in Agricultural and Biological Engineering and Pharmaceutical Sciences from Purdue University in 2008. His interest in scientific research was piqued by a three-year stint as an undergraduate researcher working on renewable energy. To combine his passion for scientific research and medicine, Haroon joined the Seleem lab in August 2011 to pursue his Ph.D. in antimicrobial drug discovery. His Ph.D. dissertation focused on the investigation of synthetic phenylthiazole small molecules as novel antibacterial agents to treat drug-resistant staphylococcal and enterococcal infections. After successfully obtaining his Ph.D. in 2016, Haroon was awarded the inaugural Purdue Institute for Drug Discovery Postdoctoral Fellowship. This competitive fellowship provided Haroon the opportunity to pursue projects repurposing FDA-approved drugs and investigating synthetic small molecules as novel antifungal agents. Presently, Haroon is working to develop novel animal models of bacterial and fungal infections to evaluate promising molecules with antimicrobial activity.
