Meet the CDSA Faculty

The CDSA faculty listed below mentor CDSA students in their independent research projects, as well as providing instruction throughout the summer program. In addition, CDSA students may work with other NC State Physics faculty on computational projects. CDSA students also interact closely with graduate students and post-docs in the NC State Astrophysics group.

John Blondin  •  Email:

Prof. Blondin's research focusses on the use of computational hydrodynamics to study astrophysical objects on the stellar scale. Recent research ranges from idealized problems such as Hoyle-Lyttleton accretion and isothermal shock instabilities to detailed studies of specific astronomical objects including SN 1987A, Kepler's SNR, and Her X-1. Undergraduate work in Blondin's group lead to the discovery of the Spherical Accretion Shock Instability (SASI) and it's role in spinning up the proto-neutron star at the center of a supernova explosion.

Rongmon Bordoloi  •  Email:

Dr Rongmon Bordoloi is an observational astrophysicist studying galaxy evolution. He is particularly interested in understanding how galaxies form and evolve, by studying the cycling of baryons into and out of galaxies. He is an expert observer, who routinely uses multi-wavelength spectroscopy and imaging (both from the ground and space) to study the galaxy baryon cycle. The baryon cycle is vital in regulating star-formation in galaxies and dictate the evolution of a galaxy. These diffuse reservoirs of gas outside galaxies contain most of the missing baryons in the Universe. Dr. Bordoloi works closely with theorists who use numerical simulations to study galaxy formation. This close interaction with theorists help in interpreting his own observational results and in constraining different theories of galaxy evolution. He also works on topics related to the formation of the first galaxies, observational cosmology, and the Fermi Bubbles.

Carla Frohlich  •  Email:

Prof. Frohlich's research covers a range of topics including astrophysical nuclear reactions, the stellar evolution of massive stars, the composition of core collapse supernova ejecta, radioactive abundances of stellar debris in protosolar nebula, and nucleosynthesis processes such as rapid neutron capture (r-process) and antineutrino-proton absorption (neutrino-p- process). She is also interested in computational simulations of supernova explosions and the roles of nuclear structure, plasma dynamics, and neutrino cross sections and transport. Other research interests include galactic chemical evolution and abundances in metal-poor stars.

Jim Kneller

 •  Email:

Prof. Kneller's research focuses upon neutrino astrophysics and nucleosynthesis at different epochs in the history of the universe from the Big Bang through to the present day. In recent years he has paid particular attention to the evolving flavor composition of neutrinos as they propagate through supernovae and how various mechanisms that drive that evolution manifest themselves in the signal we expect to observe when we next detect the burst from a galactic supernova. From this signal he hopes to tease out the unknown properties of the neutrino such as the ordering of the neutrino masses, the size of the last mixing angle and the CP phase. Other interests include Big Bang nucleosynthesis, cosmic ray spallation and cosmic and galactic chemical evolution.

Gail McLaughlin

 •  Email:

Professor McLaughlin works in the areas of nuclear and particle astrophysics. This includes neutrinos in astrophysical environments, both their effect on the environment as well as the potential for detecting the neutrinos which make their way to earth. It includes also element synthesis, the study of how neutrons and protons combine to make elements in particular astrophysical environments. She is known for her work on neutrino interactions during the formation of the rapid neutron capture elements, theoretical studies of the detection of supernova neutrinos, and work on theories which create a neutrino magnetic moment.

Stephen Reynolds

 •  Email:

Prof. Reynolds studies high-energy processes in supernova remnants, active galaxies, and other locales, in particular the acceleration of particles in strong shock waves. Synchrotron X-ray emission from shell supernova remnants, originally proposed in 1981, has now been amply confirmed and has become an important tool for the study of shock acceleration. Synchrotron X-ray emission is often mixed with thermal X-ray emission from gas shocked to temperatures of 10 MK and above, and Reynolds has performed observations with various X-ray satellites to study both thermal and nonthermal processes. Observations with the Chandra X-ray Observatory have led to the firm identification of the type of Kepler's supernova of 1604 as a thermonuclear (Type Ia) supernova, and to the discovery of the youngest supernova remnant in the Galaxy, G1.9+0.3, only about 100 years old as observed at Earth.

Ian Roederer  •  Email:

Prof. Roederer studies some of the oldest stars in the Milky Way Galaxy. The chemistry of these stars tells us about the formation of our Galaxy, how stars evolve, and the synthesis of the atoms that make up ourselves and the Universe around us.
