Jeroen Tromp joined the Department of Geosciences in July 2008 as Blair Professor of Geology and Professor of Applied & Computational Mathematics. He comes from the California Institute of Technology, where he was the Director of the Seismological Laboratory and McMillan Professor of Geophysics. From 1992 to 2000, he was a faculty member of the Department of Earth & Planetary Sciences at Harvard University. His Ph.D. (1992) and M.S. (1990) in Geophysics are from Princeton University, and he received his B.Sc. (1988) in Geophysics from the University of Utrecht in the Netherlands, of which he is a native.
Tromp’s primary research areas are in Theoretical & Computational Seismology. Research topics include: surface waves, free oscillations, body waves, seismic tomography, numerical simulations of 3-D wave propagation, and seismic hazard assessment. In collaboration with the late Princeton Geosciences faculty member Tony Dahlen he published the book Theoretical Global Seismology.
Matthieu joined Jeroen Tromp’s group as a postdoctoral research associate in January 2013. He received a Ph.D. in mathematics from University Paris Nord, in France, under the supervision of Pr. Claude Basdevant, while studying how to accelerate computational fluid dynamics algorithms on GPU at ONERA. Matthieu holds a Ms. Sc. in computer sciences from ENSEIRB Bordeaux, France, with a specialization in high performance computing.
His researches focus on how to accelerate science, in particular, numerical simulations on hardware architectures at the cutting edge of technology.

Heru joined Jeroen Tromp’s group as a postdoctoral research associate in January 2013. He received his Ph.D. (2011) in Geosciences from the University of Texas at Dallas. He received his M.Sc. (2005) and B.Sc. (2003) in Geophysics from Institute of Technology Bandung, Indonesia.
His primary research area is in Exploration Seismology including wave propagation, imaging, and inverse problems. During his Ph.D., he researched anisotropic 3D, 9-C seismic modeling and inversion, under the supervision of George McMechan.
Collaborations: Matthieu Lefebvre, Ryan Modrak, and Jeroen Tromp.
Hsin-Ying Yang is currently (2014) a visiting student research collaborator with Jeroen Tromp's group. She joined in April 2013 as a postdoctoral research associate, yet now works abroad. Yang received her Ph.D. in Geosciences from National Taiwan University in 2012. Her primary research interest is using seismic waves to study the interior of the earth from various aspects, including development of measurement method and multi-scale inversions. During her Ph.D., Hsin-Ying focused on normal-mode summation and surface-wave tomography for southern Taiwan, under the supervision of Prof. Li Zhao and Prof. Shu-Huei Hung. She is currently working on imaging seismic structures at global scales by using mode data.
Collaborations: Harriet Lau (Harvard), Hom Nath Gharti, Jessica Irving, and Jeroen Tromp.
Wenjie Lei is a graduate student at the Department of Geosciences, Princeton University. He joined Prof. Jeroen Tromp's group in 2012. Wenjie has studied at the University of Science and Technology of China from 2008, and obtained his B.S. degree in Geophysics in 2012. His primary research interests include global seismology, tomography, and seismic wavefield simulation.
Collaborations: Jeroen Tromp, Ebru Bozdag, James Smith, Hejun Zhu.
Ryan Modrak has been a graduate student in Jeroen Tromp’s group since Fall 2010. Prior to joining Princeton, he received B.Sc. degrees from Penn State University in math and geosciences and worked at Los Alamos Laboratory. His research interests include optimization and data inversion applied to both seismology and exploration geophysics. He is currently working in seismic interferometry / noise tomography and has worked in the past on joint inversion and event location problems.
