Damanveer S. Grewal is an assistant professor with a joint appointment in the School of Molecular Sciences (SMS) and the School of Earth and Space Exploration (SESE), and as a part of the Facility of Facility for Open Research in a Compressed Environment (FORCE) and the Navrotsky-Eyring Center for Materials of the Universe (MotU). Daman was born and raised in Ropar, a small town in India’s Punjab state. He received his integrated B.S. and M.S. degree from the Indian Institute of Technology (IIT), Kharagpur in 2012. He was supported by an Innovation in Science Pursuit for Inspired Research (INSPIRE) scholarship by the Department of Science & Technology, Government of India during his stay at Kharagpur. Before joining graduate school, Daman taught physical, organic, and inorganic chemistry to high school students preparing for engineering and medical school entrance exanimations and chemistry Olympiads. In December 2021, Daman received his PhD in Experimental Cosmochemistry from Rice University, Houston, where he worked with Prof. Rajdeep Dasgupta. At Rice, his research was focused on using high pressure-temperature experiments to better understand the origin of life-essential volatiles like nitrogen and carbon in the rocky bodies of the inner solar system. Daman’s PhD was supported by the Future Investigators in NASA Earth and Space Science and Technology (FINNEST) program by NASA and the Lodieska Stockbridge Vaughn Fellowship by Rice University. Daman moved to the California Institute of Technology in January 2022 to work with Prof. Paul Asimow as a Barr Foundation Postdoctoral Fellow. His postdoctoral work, which was also supported by the Caltech Center for Comparative Planetary Evolution (3CPE), focused on using meteorites to understand the cosmochemical and astrophysical processes in the early solar system. His work at ASU is on the interface between cosmochemistry, geochemistry, planetary and exoplanetary science, utilizing state-of-the-art high pressure experimental facilities at FORCE to understand the formation of habitable worlds in our solar system and beyond.

Unravelling the origin of life-essential volatiles like nitrogen (N), carbon (C), and water (H2O) in the rocky planets of our Solar System and beyond is key to answering a fundamental question in modern science: what is the recipe to form a habitable planet? N-C-H2O inventories of rocky planets are the result of a complex series of processes starting from primitive dust, organics, and ice in a protoplanetary disk, moving through planetesimals and planetary embryos, and ending with oligarchic growth and giant impact stages of planetary accretion. The goal of my research is to comprehensively understand how these processes affect the inventories of life-essential volatiles in rocky planets. To accomplish this, our research group will explore the geochemistry of planetary scale differentiation processes like core formation, degassing of magma oceans, and magma ocean crystallization using high pressure-temperature experiments, isotope geochemistry, and thermo-chemical modelling supported by meteoritic data. We will constrain the role of hitherto poorly understood physical and chemical processes within protoplanetary and planetary interiors that modulate the final N-C-H2O inventories of rocky planets in our solar system and around other stars. Understanding these processes will not only lead to the development of a general framework for the origin of N-C-H2O in rocky exoplanets but also provide important insights into the processes that eventually lead to the formation of a habitable planet and, therefore, life itself.
Our group utilizes several high pressure-temperature instruments at FORCE including multi-anvils and internal heated pressure vessels, piston cylinders, 1 atm gas mixing furnaces and vacuum furnaces. Analytical techniques include, but are not limited to, Electron Probe Micro-analyzer (EPMA), Secondary Ion Mass Spectrometry (SIMS), Raman and Fourier-transform infrared (FTIR) spectroscopy, Elemental Analyzer-Isotope Ratio Mass Spectrometry (EA-IRMS) and Multiple-Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS).
