Jonathan Carroll-Nellenback, Ph.D., is an Assistant Professor of Physics and Astronomy and a computational scientist with the Center for Integrated Research Computing, and where he works with researchers to build and utilize computational and data analytics tools to solve research problems. Trained as a computational physicist, Jonathan applies his experience working with high-performance computing and visualization tools to a variety of disciplines, including health sciences. He also has experience adapting and optimizing code for the Blue Gene/Q environment. 

Jonathan works directly with faculty and students from over 40 departments and centers across the University to demonstrate novel ways to visualize and analyze data in the VISTA Collaboratory. Using the direct connection to the supercomputers in the Research Data Center, Jonathan helps investigators integrate computational and visualization tools into their research to enable new discoveries.

He received his Bachelors in Math from Asbury College and his Ph.D. in Physics and Astronomy from the University of Rochester, where he studied the turbulent formation and evolution of molecular clouds and the numerical modeling of highly compressible fluids. Part of Jonathan’s thesis was the design and construction of AstroBEAR, a massively parallel Adaptive Mesh Refinement code in use at the University of Rochester and publicly available to the research community.
