Brian Clark works on particle astrophysics, specifically high-energy neutrino astronomy. He received his PhD from The Ohio State University in 2019, where he was a National Science Foundation (NSF) Graduate Research Fellow. At OSU, he worked on the Askaryan Radio Array (ARA) experiment, which seeks to observe the highest energy neutrinos (above 10 PeV) through the radio detection technique. He worked on all aspects of the experiment, spanning data analysis, simulation, and detector development, including a deployment to the South Pole. After completing his PhD, he became a National Science Foundation Astronomy and Astrophysics Postdoctoral Fellow at Michigan State University. At MSU, he expanded his experimental efforts to include the IceCube Neutrino Observatory. His current efforts include work on ARA, IceCube, and next generation observatories like the Radio Neutrino Observatory in Greenland (RNO-G) and IceCube-Gen2. He currently serves as co-convener of the IceCube Diffuse Neutrino Group and as analysis co-coordinator for ARA.

Ronald Walsworth earned his B.S. in Physics from Duke University and his Ph.D. in Physics from Harvard University. His research interests are in developing precision measurement tools and applying them to diverse problems across the physical and life sciences. Walsworth is the recipient of the Francis Pipkin Award in Precision Measurements from the American Physical Society; the Smithsonian Institution Exceptional Service Award; and the Duke University Faculty Scholar Award. He is a Fellow of the American Physical Society and serves as a Distinguished Traveling Lecturer for the Division of Laser Science of the American Physical Society. Walsworth is also a Minta Martin Professor in the UMD Department of Electrical and Computer Engineering and Founding Director of the Quantum Technology Center.
Greg Sullivan received his Ph.D. from the University of Illinois and did postdoctoral work at the University of Chicago before joining the UMD faculty in 1995. He is a Fellow of the American Physical Society, and has been named a UMD "Rainmaker" for his prodigious research funding. He has served as the Department's Associate Chair for both Graduate Studies and for Facilities and Personnel, and has held several key leadership positions in his field of high energy physics. He has worked on the on the IceCube experiment at the South Pole, including a role as spokesperson from 2011-13. Physics World named the first observations of cosmic neutrinos by the IceCube Neutrino Observatory the 2013 Breakthrough of the Year. Dr. Sullivan is a co-recipient of the 2016 Breakthrough prize in Physics, serves on the advisory committee for the NSF directorate of geosciences, and also served on the committee of visitors for NSF Antarctic sciences.

Kara Hoffman received her Ph.D. at Purdue University, followed by postdoctoral appointments at CERN in Geneva, Switzerland and the University of Chicago. She joined the UMD faculty as an assistant professor in 2004, was promoted to associate professor in 2010 and professor in 2015. Recognition has included the NSF Career Award, the CMPS Board of Visitors Distinguished Junior Faculty Award, and the Purdue University physics department's Outstanding Alumna Award in 2013. Her current work is in particle astrophysics, centered on the IceCube Neutrino Observatory and the Askaryan Radio Array at the South Pole. Physics World named IceCube’s first observations of cosmic neutrinos the 2013 Breakthrough of the Year.

Jordan Goodman is a Distinguished University Professor and the former Chair of Physics Department at the University of Maryland. His area of research, Particle Astrophysics, studies cosmic radiation to better understand the properties of elementary particles and the processes in space that produce these particles. This field blends elements of high energy physics and astrophysics. Starting with his Ph.D. work, which showed evidence for an abundance of heavy elements such as iron in high energy cosmic rays, he has worked to understand the nature of cosmic rays which hit the earth. Previously, his work has concentrated on two experimental efforts-- Milagro and IceCube. He is now the Principal Investigator and US Spokesperson of the HAWC Gamma Ray Observatory. He is a UMD Distinguished Scholar-Teacher and Distinguished University Professor.
