Research areas

My current research at AUS is on ultrafast processes in nanoparticles using the femtosecond laser and reaction microscope (nanoTRIM) housed at the Materials Research Center (MRC). We investigate the interactions of nanoparticles with ultrashort, intense laser pulses, aiming to explore and precisely tailor their physical and optical properties. This work has applications in a variety of fields, including materials science, atmospheric physics, and planetary chemistry. I have vast research experience in the areas of Experimental Atomic and Molecular Physics, particularly on ...

Dr. Najeeb Punnakayathil

Assistant Professor

Dr. Najeeb Punnakayathil is an experimental physicist specializing in atomic and molecular physics with expertise in designing and developing advanced experimental setups and data acquisition systems. His research focuses on investigating the effects of radiation on molecular systems, simulating astrophysical environments, and conducting experiments under ultra-high vacuum and cryogenic conditions. He is a recipient of the prestigious NASA Postdoctoral Fellowship and has several years of post-Ph.D. research experience. Currently, he is working on the interaction of ultra-short laser pulses with nanoparticles using nanoTRIM experimental set-up available at AUS. Before joining AUS, he was as a scientist at NASA Ames Research Center, USA.
