Ravi Prasad, Ph.D., joined CAIS in 2008, and has over 20 years of experience in particle accelerator based research. Dr. Prasad began his career in the field of nuclear reactions and earned his Ph.D at Institute of Physics, Bhubaneswar, India, where he was involved in the theoretical study of nuclear reaction mechanism using Langevin simulations and experimental study of heavy-ion induced fusion-fission reactions. Later, he pursued other applications of accelerators using IBA methods, such as PIXE, RBS and ERDA. He was a postdoctoral fellow at AGLAE, C2RMF, Paris from 1999–2000 where he studied archaeological samples from the Harappan site of Dholavira using the external microbeam PIXE facility at AGLAE. As a postdoctoral fellow at University of North Texas, Denton, he worked on trace element accelerator mass spectrometry (TEAMS) and moved on to radiocarbon AMS when he joined Institute of Physics, Bhubaneswar in 2001 as a faculty member.  Besides the radiocarbon AMS research at CAIS where he manages the two AMS accelerators, he also pursues his research interests in computational physics. Dr. Prasad became Associate Director of CAIS in Fall of 2023.
