Graduate Studies Leadership

Jean-Pierre Delplanque
Vice Provost and Dean - Graduate Studies

Jean-Pierre Delplanque was appointed vice provost and dean of Graduate Studies at the University of California, Davis, in January 2019. Prior to that appointment, he served as Associate Dean for Graduate Students and Postdoctoral Scholars in Graduate Studies and as Associate Dean for Undergraduate Studies in the College of Engineering. In his current role, his focus is to cultivate an inclusive, equitable learning environment for graduate students and postdoctoral scholars so that they are equipped to spearhead discoveries with global impact.

As a professor of Mechanical and Aerospace Engineering, his research and educational activities focus on the multi-scale modeling and numerical simulation of complex fluid and thermal processes and systems. Applications are interdisciplinary, 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.

A first generation college graduate, Delplanque received an Engineering Diploma from Ecole Nationale Supérieure d’Electrotechnique, d’Electronique, d’Informatique, d’Hydraulique et des Télécommunications (ENSEEIHT), Toulouse, France, a post-graduate diploma (“D.E.A.”) in mechanics from the National Polytechnic Institute of Toulouse, France, and a M.Sc. and Ph.D. in Mechanical and Aerospace Engineering from the University of California, Irvine.

He joined the faculty of the Department of Statistics at UC Davis in 2004 after serving on the technical staff of AT&T Bell Laboratories. His international reputation as a member of the core development team of the R system, a computing language and environment widely used worldwide by statisticians, is indisputable. He has authored or significantly contributed to more than 120 R packages released as part of the Omegahat project. He is the co-author of 2 books and is one of 4 co-editors of “The R series”, a book series. He currently serves as Director of the Data Science Initiative.

Professor Temple Lang has extensive experience in Graduate Education, having served as Master Adviser in the Graduate Program in Statistics, member of the Graduate Council, member of the Graduate Educational Policy, member and vice chair of the Graduate Program Review Committee, and member, vice chair, and chair of the Graduate Program Review Closure Committee. These experiences have given him the opportunity to interact frequently with Graduate Studies staff and prepared him remarkably for the duties of the interim associate dean for graduate programs.
