Dr. Steven Biegalski
RSEL Director
Dr. Sharmistha Mukhopadhyay
RSEL and Ops Manager
Steven Biegalski is the Chair of Nuclear and Radiological Engineering and Medical Physics Program at Georgia Institute of Technology. He has three degrees in nuclear engineering from University of Maryland, University of Florida, and University of Illinois, respectively.
Early in his career Dr. Biegalski was the Director of Radionuclide Operations at the Center for Monitoring Research. In this position Dr. Biegalski led international efforts to develop and implement radionuclide effluent monitoring technologies. This work supported both US national capabilities and international treaties. Dr. Biegalski was a faculty member at The University of Texas at Austin for 15 years and held the position of Reactor Director for The University of Texas at Austin TRIGA reactor for over a decade. He has advised 25 Ph.D. students to graduation and holds Professional Engineering licenses in the states of Texas and Virginia.
Before joining Georgia Tech in 2020, Dr. Mukhaopadhyay worked with Sun Nuclear Corporation, Melbourne, FL, primarily developing the new SunSCAN 3D water scanning system. She has also worked on developing dual neutron gamma detector with elpasolite scintillator at Radiation Monitoring Devices, Boston, MA.
Her primary responsibility as the RSEL Manager is supporting faculty and students in pursuing cutting-edge research in the medical physics and nuclear & radiological engineering fields. The RSEL facility houses several laboratory spaces with various equipment and radiation instrumentation devices. Dr. Mukhopadhyay helps operate these tools for various experimental procedures and coordinates efforts across the university and with external partnerships as needed.
Dr. Eric S. Elder
Professor, Emory University and Director.
Varian Clinical Linear Accelerator Laboratory
Dr. Elder’s research centers on techniques for adaptive radiation therapy, adjustments to a patients radiation treatment caused by changes in patient position, anatomy, or motion or due to tumor response. His visualization methods for these changes include 3D and 4D computed tomography and linear accelerator mounted cone beam computed tomography, radiography, and respiratory gated fluoroscopy and radiography. After visualization and tumor delineation, treatment planning is performed to adapt treatment properly. His work also explores use of electronic portal dosimetry to measure exit dose. Dr. Elder serves as joint faculty with Emory University and Georgia Tech.
