William H. Matthaeus

William H. Matthaeus is the Martin A. Pomerantz Chair of Physics & Astronomy at the University of Delaware, where he has been a faculty member since 1983. He is affiliated with the Bartol Research Institute, housed in the H. Rodney Sharp Laboratory on the University of Delaware campus. His work focuses on space physics, plasma physics, turbulence theory, and computational physics.

Dr. Matthaeus received his B.A. degree in physics and philosophy from the University of Pennsylvania in 1973, followed by a Ph.D. from William and Mary in 1979. His academic journey included a National Academy of Sciences Research Associate position from 1980-1982 before joining the University of Delaware.

Matthaeus's research spans solar wind physics, space plasmas, kinetic microinstabilities, and space mission development. His work involves theoretical, computational, and observational approaches to understanding plasma turbulence and magnetic reconnection in space environments. He has made significant contributions to understanding energy transfer in magnetohydrodynamic turbulence, solar wind dynamics, and particle acceleration mechanisms.

His recent publications demonstrate a continued focus on multiscale plasma phenomena, with particular attention to turbulence in the solar wind, magnetosheath, and near-Sun environments. The research utilizes data from multiple spacecraft missions including Parker Solar Probe, MMS, and HelioSwarm, combined with sophisticated numerical simulations.

Dr. Matthaeus serves as director of the Delaware NASA Space Grant Consortium and the Delaware NASA EPSCoR program. He is a co-investigator on several major spacecraft missions including Cluster/PEACE, the Magnetospheric Multiscale mission, the Parker Solar Probe ISOIS instruments, the Interstellar Mapping and Acceleration Probe, PUNCH and Helioswarm. For over a decade, he has organized the Arcetri Workshop on Plasma Astrophysics in Florence, Italy, fostering international collaboration in the field.

His research group at the Bartol Research Institute maintains active collaborations with scientists worldwide and contributes to advancing our understanding of fundamental plasma processes that govern space weather and astrophysical phenomena.
