I am a member of the High Energy Physics and Mathematics and Computer Science Divisions at Argonne National Laboratory, a Senior Member of the Kavli Institute for Cosmological Physics at the University of Chicago, and a Senior Fellow in the Computation Institute, a joint collaboration between Argonne National Laboratory and the University of Chicago.
My research interests cover the broad sweep of classical and quantum dynamical systems, from field theories to particles, and from the largest scales to the smallest. Specifically — moving from larger to smaller scales — I have worked on problems in cosmology, astrophysics, accelerator physics, condensed matter physics, atomic and quantum optics, and particle physics. Some of my more general interests include quantum dynamics of open systems, nonlinear dynamics and nonequilibrium statistical mechanics, and stochastic ODEs and PDEs. Although most of my work has been theoretical, I have also been involved in experimental and observational projects.
For over the last two decades I have been very interested in the intelligent application of parallel supercomputers to attacking physics problems. This has led to algorithm and code development in a variety of fields and on a variety of platforms, beginning with the Connection Machines in the early 1990’s and leading on to the current BG/Q system, Mira, now installed at Argonne.
More recently I have become involved in efforts — with cosmology as the primary arena — to apply advanced statistical methods to complex inference problems where the datasets are very large (with small statistical uncertainties) and the forward model predictions involve supercomputer calculations. I am a member of the Dark Energy Survey (DES) and the Large Synoptic Survey Telescope (LSST) projects.
I am always looking for new things to discuss and think about. Please send me email (habib[at]anl.gov) if interested. Students are most welcome!
My undergraduate preparation was at the Indian Institute of Technology, Delhi and my Ph.D. is from the University of Maryland, obtained under the guidance of Bei-Lok Hu. I was a postdoc with Bill Unruh at the University of British Columbia and postdoc and later staff member in the Theoretical Division at Los Alamos National Laboratory before moving to Argonne in 2011.
