Bio for invited talks and event announcements:


Mustapha Ishak is a theoretical astrophysicist and Professor of Physics and Astrophysics at the University of Texas at Dallas. He completed his Ph.D. degree with distinction in 2002 at Queen's University in Canada in General Relativity and Cosmology, and received the prestigious fellowship of the Research Council of Canada. After that, he joined Princeton University as a researcher in the fields of cosmology, before joining UT-Dallas as a faculty in 2005, where he has been since. His scientific work has been disseminated in over 80 publications with nearly 4000 citations. Mustapha Ishak provided seminal work on testing gravity at cosmological scales, constraining possible causes of cosmic acceleration, constraining cosmological models, and intrinsic alignment of galaxies as an astrophysical systematic effect in weak gravitational lensing. Mustapha Ishak was elected in 2021 as Fellow of the American Association of Advancement of Sciences (AAAS) with quote: "For distinguished contributions to the field of theoretical cosmology, particularly for testing modifications to general relativity at cosmological scales, and for sustained excellence in teaching and mentoring of students." Also, for teaching and mentoring students, he received in 2007 and 2018, the Outstanding Teaching Award from the Natural Sciences and Mathematics School, and in 2021, and the President's Teaching Excellence Award at UT-Dallas. Mustapha Ishak is an active member and leader in the Legacy Survey of Space and Time - Dark Energy Science Collaboration (LSST-DESC) and the Dark Energy Spectroscopic Instrument (DESI) survey collaboration. These two international collaborations will revolutionize our understating of the universe, gravity, and cosmic acceleration. In 2002, one of his publications was voted by the Editorial Board of Classical and Quantum Gravity as one of the journal's highlights of the year. In 2008, one of his publications was selected by Nobel Laureate Gerardus't Hooft to be on the Chief Editor List of the Foundation of Physics Journal. In 2013, his publication in Physical Review Letters was selected by the editors to be highlighted in Spotlighting Exceptional Research in Physics website of the American Physical Society. In 2019, he published an extensive invited review (204 pages) on Testing General Relativity in Cosmology in the prestigious Living Reviews in Relativity Journal. Mustapha Ishak delivered over 70 invited plenary and public talks including the 2019 Opening Plenary Talk of the International Conference of the 100th anniversary of the 1919 Solar Eclipse expedition and experiment that confirmed the Theory of General Relativity of Einstein.

A recent video-interview at UT-Dallas about research and teaching with special advice to students:




Chronological brief biosketch:


I am a theoretical astrophysicist. My recent research projects and interests are in Physical Cosmology, Gravitational Lensing, and General Relativity (see next section).  I am involved in theoretical, numerical, and data-related projects. I am a full member of the LSST Dark Energy Science Collaboration (DESC) working mainly within the Theory-Joint-Probes (TJP) and the Weak Lensing (WL) groups.

I completed my Ph.D. in 2002 in Cosmology and General Relativity with Prof. Kayll Lake at the Physics Department at Queen's University at Kingston in Canada. My graduate work included investigations in inhomogeneous cosmological models and Exact Solutions to Einstein's Equations; an inverse approach to Einstein's equations; oscillation modes in compact astrophysical objects; and matching spacetimes using junction conditions leading to Wormwholes and thin shells.

Then, I joined the Physics Department at Princeton University as a postdoctoral fellow where I worked on projects in physical cosmology, cosmic acceleration and gravitational lensing with Prof. Steinhardt, Prof. Seljak and other researchers. After that, I worked as a Research Associate at the Astrophysical Sciences Department at Princeton in collaboration with Prof. Spergel and other researchers on cosmic acceleration and testing gravity at cosmological scales. While there, I organized the Princeton & IAS Gravitational Lensing Seminar and  taught (as preceptor with lecturer appointments) at the Physics Department (Physics 103) and the Astrophysics Department (Astro 203).

In 2005, I started a professorship position at the Department of Physics at the University of Texas at Dallas (UT Dallas). I discovered that a real thirst for Cosmology and Astrophysics exists within the students at UT Dallas and also the general public in the Dallas Metroplex Area, so I launched a number of initiatives and activities in response to that. Over the years, I formed a Cosmology, Astrophysics and Relativity Group that now counts 5 faculty and ~20 graduate students.

I also developed software packages with collaborators including (as lead developper) the Interactive Geometric Database of Exact Solutions of Einstein's Field Equations (GRDB), and later on the package called ISiTGR (Integrated Software in Testing General Relativity) that is an integrated set of modified modules for the software package CosmoMC for use in testing whether observational data is consistent with general relativity on cosmological scales. Click here for ISiTGR webpage. The most recent version is available on the Github repository: Click here for ISiTGR repository.

The courses I taught at UT-Dallas include undergraduate courses PHYS2325 Mechanics, PHYS3312 Classical Mechanics, PHYS4V89 Cosmology, PHYS1100 Fun of Physics, and graduate courses: PHYS5303 Math Methods for Physics III, PHYS5395 Cosmology, PHYS5311 Classical Mechanics, PHYS5391 Special Relativity, and PHYS5392 General Relativity. I received in 2007 and 2018 the Award for Outstanding Teacher of the Year from the School of Natural Sciences and Mathematics at UTD: 2007 news article ; 2018 news article. And the President's Teaching Excellence Award in 2021: 2021 news article. For a detailed list of my course teaching (until 2015) click here..

My research work received funding from NASA, DOE, NSF, private foundations and corporate sector.

I served as proposal reviewer for NSF, NASA, the Research Foundation of Canada, CONICYT Chile, The Foundation of Polish Science, The Netherlands Organisation for Scientific Research, and the Texas Space Grant Consortium. I serve regularly as referee for Physical Review Letters, Physical Review D, Astronomy & Astrophysics, Classical and Quantum Gravity, Monthly Notices of Royal Astronomy Society, General Relativity and Gravitation, Euro-Physics Letters and Physics Letters B. I served on the UTDallas senate for 9 years and participated or chaired over 20 university or school committees. I co-chaired the local and scientific organizing committees of the 27th Texas Symposium on Relativistic Astrophysics. The symposium received 470 participants, over 300 talks in 49 parallel sessions; 24 plenary and review talks, and a public lecture attended by over 1300 people. More info and the online proceedings are available at http://nsm.utdallas.edu/texas2013. I manage and organize the activities and expansions of our Cosmology, Astrophysics and Relativity Group at UT Dallas.
