Dr. Haas' research interests focus on radiation detection for nuclear arms control and non-proliferation, including the fundamental physics of radioactive decay processes, fission yields, and detection techniques. He is one of five surrogate inspectors from the United States for the Comprehensive Nuclear-Test-Ban Treaty and is a technical advisor for US nuclear arms control and non-proliferation policy development. He has also contributed to the analysis of the Fukushima nuclear reactor accident and nuclear tests in the Democratic Peoples' Republic of Korea.

Dr. Haas joined the faculty of The University of Texas after eight years at Pacific Northwest National Laboratory where he worked as a Senior Research Engineer in the National Security Directorate. He earned his bachelor's, master's, and doctoral degrees from UT Austin.
