He was a von Karman Instructor and Prize Research Fellow in Applied Mathematics at Caltech from 1993-1997, and was an Assistant Professor of Mathematics at UC Irvine from 1997-1998, before moving to the Mathematics Department at UC San Diego in 1998. He was promoted to tenured Associate Professor in 2000, to Professor of Mathematics in 2003, and appointed as Professor of Physics in 2009. He is the recipient of an NSF CAREER Award and a Hellman Fellowship, and is coauthor of a graduate textbook on applied analysis and partial differential equations with Ivar Stakgold. He was selected as a SIAM Fellow in 2016, and currently holds a Chancellor's Associates Endowed Chair at UCSD.

Prof. Holst directs the Mathematical and Computational Physics Research Group (MCP) within the Mathematics and Physics Departments at UCSD, and is the lead developer and architect of the Finite Element ToolKit (FETK). He currently serves as one of the three founding Co-Directors of the Center for Computational Mathematics (CCoM) within the Mathematics Department. He was a founding Co-Director for the interdisciplinary M.S. and Ph.D. Programs in Computational Science, Mathematics, and Engineering (CSME), and served as the lead director from the founding of the Program in 2007 through 2020. He is involved in a number of interdisciplinary research institutes and research training programs on campus, including the Center for Computational Mathematics (CCoM), and the Center for Astrophysics and Space Sciences (CASS). His research is supported by NSF, NIH, DOE, AFOSR, and DTRA, as well as by industrial sponsors and private foundations. As of 2020, he has been the primary supervisor for 17 completed doctoral students, 29 postdoctoral students, and 23 undergraduate honors thesis and/or REU summer research students, of which 5 went on to complete doctorates in pure or applied mathematics at Cambridge, Caltech, Purdue, CMU, and UT Austin.

  • The NSF-funded mathematics institute ICERM is hosting a special program on Advances in Computational Relativity over the entire Fall 2020 term (September 9-December 11, 2020). I had planned to be in residence at ICERM all Fall as part of a year-long sabbatical, but the Covid-19 pandemic has led to a number of scheduling changes. This workshop is now being done mostly remotely over Zoom. I will still be taking part, but from San Diego; if you are interested in the subject and/or the lectures, a link to the program is [ here ].

  • A youtube video of our recent research work was released in January 2020, and can be found [ here ]. The video illustrates the meshing technology described in our newly published article: An Open Source Mesh Generation Platform for Biophysical Modeling Using Realistic Cellular Geometries. Credit for the video and much of the technology behind it goes to UCSD Postdoctoral Researcher Chris Lee, and to my other collaborators in the Rangamani Research Lab in MAE at UCSD.

  • Together with Doug Arnold, David Garfinkle, Luis Lehner, and Reinout Quispel, I co-organized a workshop at the Isaac Newton Institute for Mathematical Sciences at Cambridge University in England that will run from September 30, 2019 through October 4, 2019. The workshop on Structure Preservation and General Relativity is part of the larger Program on Geometry, Compatibility and Structure Preservation in Computational Differential Equations that is running at the Newton Institute in Fall 2019.

    I gave one of the opening lectures at the workshop on Some Research Problems in Mathematical and Numerical General Relativity. The slides from the lecture can be found [ here ], and an abstract and the video of the lecture can be found [ here ]. The video may also be accessed in various formats here [ m4v  | mp4  | webm  | mp3 ]

  • In January 2018, we will be running a UCSD workshop and jointly organizing a related multi-part minisymposium at the JMM Conference at the San Diego Convention Center; see the GPDE2018 website for more information about the workshop and the JMM minisymposium.

  • The 2017 Nobel Prize in Physics was awarded to three of the key scientists involved in the development of LIGO and its eventual successful first detections of gravitational waves. The official announcement can be found [ here ].

  • Our group was approached by the AMS for a survey article on mathematical and numerical general relativity, to help explain to the broader mathematical sciences community the mathematics, science, and technology behind the recent gravitational wave detections (there have now been several detections). The article will appear in the October 2016 issue of the Bulletin of the American Mathematican Society, and when available it will be published online [ here ].

  • At 10:30am EST on 11 February 2016, the National Science Foundation, together with the LIGO Scientific Collaboration, announced that the first direct detection of a gravitational wave was made on 14 September 2015 by the twin LIGO devices located in Livingston, Louisiana and Hanford, Washington. The LIGO project, which at over 600 million dollars is the single most ambitious and expensive scientific project ever supported by NSF, represents an incredible scientific and engineering achievement. This successful detection will substantially change astronomy and other areas of physics forever, and the discovery is viewed as comparable in importance to the recent discovery of the Higgs Boson using the Large Hadron Collider. Our group put together some additional information about the LIGO Project for my graduate students, which can be found [ here ]. Links to the announcement and joint press conference by NSF and by the LIGO Scientific Collaboration, and a link to the Phys. Rev. Lett. article on the discovery that was published online simultaneously with the announcement, can be found below:
  • The year 2015 is the one-hundred year anniversary of the theory of general relativity; in celebration, there are a number of local, regional, national, and international workshops and conferences being held this year. One such conference is the Focus Program on 100 Years of General Relativity being held at the Fields Insitute in Toronto during May and June 2015. As part of this conference, I co-organized one of the Focus Weeks on Constraint Equations and Mass-Momentum Inequalities, and he gave two of the overview talks. The slides from the talks can be found [ here ].

Since 2007, we have run a campus-wide CSME Seminar Series covering a broad range of topics in applied mathematics, physical sciences, and computational science. The CSME series, with typically 2-3 lectures each quarter, complements the weekly CCoM Seminars as well as other seminars that run each quarter. The CSME Seminar Speakers include both UCSD faculty as well as visiting faculty from other institutions. The seminar titles and abstracts for CSME and CCoM Seminars are posted on the CCoM/CSME Seminar website and are also announced on the CSME-L mailing list.
