| Research Interests | Dr. Abel's research interests are ab initio supercomputer calculations in cosmological and astrophysical systems. He has shown from first principles that the very first luminous objects are very massive stars and has developed novel numerical algorithms using adaptive mesh refinement simulations capturing over 14 orders of magnitude in length and time scales. He currently continues his work on the first stars and first galaxies and their role in chemical enrichment and cosmological reionization. Recently he has also studied relativistic astrophysical flows and magneto-hydrodynamic effects in present day star formation. His research program focuses on building galaxies one star at a time. He heads the KIPAC computational physics department which provides super-computing resources and algorithmic advice to members of KIPAC. | ||||||||

| Research Interests | String theory and quantum field theory, and their applications to elementary particle theory, theoretical cosmology, and condensed matter physics. My most recent work has been focused on exhibiting new phenomena in toy models of strongly correlated electron systems, and on designing new models of supersymmetry breaking and mediation which could be relevant to physics at the weak scale. I also have a longstanding interest in early universe cosmology, where my work has included the construction of inflationary models in string theory, and computations of the general spectrum of density fluctuations that can emerge in any single-field model of inflation. Prior research interests have included string duality and exact results in supersymmetric theories; space-time topology change in string theory; generalizations of AdS/ CFT to less symmetric and more realistic field theories; and flux compactifications of string theory to four dimensions. | ||||||||

| Research Interests | Professor Chao-Lin Kuo's group studies the most ancient light, the Cosmic Microwave Background (CMB) radiation, emitted when the universe was in its infancy. The polarization in the CMB contains information on the birth of the universe (Inflation), as well as its subsequent evolution. Professor Kuo is involved in both the cosmological interpretation and instrumentation/technology development. The group frequently adopts advanced experimental techniques, such as cryogenics, superconductivity, and low-noise measurements, to maximize detector's sensitivity to the faint CMB signal. The ongoing projects are all CMB polarization experiments based at the South Pole: • BICEP/BICEP2/Keck Array: A series of degree-scale experiments targeting signatures of primordial gravitational waves with increasing sensitivity. • POLAR-1/POLAR Array: Few-arcminute-scale polarization experiments targeting both gravitational waves and gravitational lensing signatures. Professor Kuo was awarded an MRI (Major Research Instrumentation) grant from the NSF in 2010 to develop POLAR-1. | ||||||||

| Research Interests | Prof. Jogesh Pati has made pioneering contributions towards the notion of a unification of fundamental particles - quarks and leptons - and of their gauge forces: weak, electromagnetic and strong. His formulation, carried out in collaboration with Abdus Salam, of the original gauge theory of quark-lepton unification, and their resulting insight that violations of baryon and lepton numbers, especially that would manifest in proton decay, are likely consequences of such a unification, provide corner stones of modern particle physics today. The suggestions of Pati and Salam of the symmetry of SU(4)-color, left-right symmetry and of the associated existence of the right-handed neutrinos now provide some of the crucial ingredients for understanding the observed masses of the neutrinos and their oscillations. For his pioneering contributions towards a "Quest for Unification", he received the Dirac Medal for the year 2000 (with Howard Georgi and Helen Quinn). | ||||||||

| Research Interests | Professor Silverstein attacks basic problems in several areas of theoretical physics. She develops concrete and testable mechanisms for cosmic inflation, accounting for its sensitivity to very high energy physics. This has led to a fruitful interface with cosmic microwave background research, contributing to a more systematic analysis of its observable phenomenology. Professor Silverstein also develops mechanisms for breaking supersymmetry and for stabilizing the extra dimensions of string theory to model the immense hierarchies between the cosmological horizon, electroweak, and Planck scales in nature. In addition, Professor Silverstein uses the ultraviolet completion of gravity afforded by string theory to address questions of quantum gravity, such as singularity resolution and the physics of black hole and cosmological horizons. Professor Silverstein also uses modern techniques in quantum field theory to model strongly coupled phenomena motivated by measurements in condensed matter physics. | ||||||||
