Biographical Sketch:

Dr. Jiexin Deng received his Master’s degree in pharmaceutical sciences from the University of North Carolina at Chapel Hill and his Ph.D. degree in pharmacometrics and systems pharmacology from Univ. of Florida. Dr. Deng has worked on projects solving clinically relevant questions in drug development and has published multiple papers in high-impact journals including Clinical Pharmacology & Therapeutics. Dr. Deng was selected to present two posters on his research on physiologically based pharmacokinetic (PBPK) modeling of gefitinib disposition at the American Society for Clinical Pharmacology and Therapeutics (ASCPT) 2014 Annual Meeting and was selected as the 2015 American College of Clinical Pharmacology (ACCP) Annual Meeting Student/Trainee Award Winner for his work investigating DDI-GDI (Drug-Drug Interaction and Gene-Drug Interaction) convergence using PBPK modeling and simulation. The work that Dr. Deng co-authored in warfarin dose optimization has also received recognition at the ASCPT 2017 meeting as the recipient of the Presidential Trainee Award and also the Jason Morrow Trainee Award for the top scoring trainee abstract. After graduation, Dr. Deng has joined the Clinical Pharmacology group in Early Clinical Development at Pfizer Inc.


Having the opportunity to enroll as a Ph.D. student at the Center was a life-transforming experience for me. I thoroughly enjoyed my time there and was able to learn practical skills that are highly sought after by the pharmaceutical industry as well as regulatory agencies such as FDA. The research questions that are being investigated and answered are cutting edge problems in clinical pharmacology. Every year at national conferences such as ASCPT, ACoP, or ACCP, students and post-docs at the Center were able to bring back prestigious awards, which really speaks to how relevant the research at the Center is in the field of pharmacometrics and systems pharmacology. As a Ph.D. student, I feel especially lucky to be able to pursue a statistics minor alongside the Ph.D. program in Pharmaceutical Science. Since clinical pharmacology and pharmacometrics call for cross-disciplinary skill sets, having a good background in statistics really allows me to communicate and collaborate with statisticians in the industry setting. Furthermore, I was able to work closely with internal and external collaborators and learn how to effectively solve problems as a team. All these components are what make the Center such as ideal place to learn and contribute in this field. I would like to give a special thanks to my mentors, Dr. Larry Lesko, Dr. Stephan Schmidt, and Dr. Guohua An, whose expertise, patience, and understanding have meant so much to me during my time as a Ph.D. student.
