Graduate Studies Leadership

Jean-Pierre Delplanque
Interim Vice Provost of Graduate Education
Interim Dean, Graduate Studies

Jean-Pierre Delplanque is a Professor of Mechanical and Aerospace Engineering. He serves as Interim Vice Provost of Graduate Education and Interim Dean of Graduate Studies. His research and educational activities focus on the multiscale modeling and numerical simulation of complex fluid and thermal processes and systems. Applications are interdisciplinary in nature, crossing the boundaries between mechanical, chemical, and biomedical engineering, and materials science, with specific examples ranging from the characterization of patient ventilator asynchrony in the critical care setting to additive manufacturing technologies. Professor Delplanque received a Ph.D. in Mechanical and Aerospace Engineering from UC Irvine.

His experience with students from a variety of angles—on top of his personal experience as an international graduate student himself—equips him with the ability to work closely with the diverse UC Davis community. JP is eager to work both individually and collectively with students to tackle the challenges they encounter on their graduate journey. “There are several facets to the job. One of them is to help students and faculty to work out disagreements that arise, to help advise and remedy problems regarding policies,” he says. “Students come here usually because they can’t find a solution within their own program or with their own faculty members.” JP provides guidance for graduate students to the resources offered by UC Davis.
