Experimental Scientist

Thank you for taking the time to explore my website and for showing interest in getting to know me better. Below, I've provided a brief overview of my academic journey: After completing my primary and intermediate education, I enrolled in the 5-Year Integrated Masters program at the University of Hyderabad, majoring in physics. During the initial two years of this dual degree program, I was required to study Physics, Chemistry, Mathematics, and Biology. It was during this period that I gained exposure to these four major fields and recognized chemistry as a discipline bridging the realms of Physics and Biology. While I found chemistry fascinating, I also understood that a successful research career in this field necessitates a strong grasp of physics and mathematics. Consequently, I chose physical sciences as my major field, and I now perceive no distinct boundaries between these disciplines.

Following Masters degree, I earned my Ph.D. from the University of Manitoba in 2020 under the guidance of Prof. Johan van Lierop. My research focused on two primary areas: (1) investigating transition metal and rare-earth nanoscale oxides to understand the interplay between orbital hybridization and magnetism, and (2) collaborating with the Toyota Research Institute - North America to explore the impact of oxygen vacancies in ceria on NOx catalysis. My expertise involves using laboratory-based Quantum Design SQUID magnetometers, in-situ and ex-situ Mössbauer spectroscopy, low-temperature and high-temperature systems, cryostats for liquid nitrogen and liquid helium, closed-cycle refrigeration, mechanical pumps, diffusion pumps, turbomolecular pumps, and high-temperature furnaces. Throughout my doctoral studies, I frequently used the facilities at Argonne National Laboratory in Chicago, USA, employing soft and hard X-ray absorption spectroscopy, as well as X-ray Magnetic Circular Dichroism techniques. During this time, I contributed to the development of an in-situ transmission Mössbauer spectrometer sample cell, specifically designed for studying solid-state and gas reactions. 

In 2019, prior to defending my thesis, I was offered a postdoctoral position at Dr. Kug-Seung Lee's 8C beamline in South Korea. There, I sharpened my skills in X-ray Absorption Fine Structure spectroscopy and refined my expertise in experiments, data analysis, simulations, and python programming. In Dr. Lee's lab my research focused on atomic-level materials design, and characterization for electrochemical energy conversion, and magnetism of single-atom incorporated nanomaterials. Here, I also assisted in maintaining the beamline and provided user support to external users from prestigious laboratories in Korea. Additionally, I collaborated with leading research groups focusing on single-atom catalysis for electrochemical applications.

To further deepen my knowledge of spectroscopy techniques and understand their application to energy storage materials, I transitioned to the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, in January 2022. As a postdoctoral scientist at the ID26 beamline, I am involved in using advanced X-ray spectroscopy techniques such as high energy resolution fluorescence detected (HERFD) XAS, X-ray emission spectroscopy (XES), and Resonant X-ray emission spectrosocpy (RIXS) under the supervsion of Dr. Pieter Glatzel. At ID26, I provide local contact service to external users on a variety of in-situ and operando techniques such as HERFD-XAS, XES, and Resonant Inelastic X-ray Scattering. I am highly passionate about using synchrotron radiation facilities to investigate electronic structures, consistently seeking opportunities for personal growth while helping colleagues in achieving their research objectives.
