Exploring the Frontiers of Materials Science: An Interview with Dr. Priya Vashishta

By Carson Vest

Introduction

 

Dr. Priya Vashishta, a professor with appointments in Chemical Engineering & Materials Science, Computer Science, and Physics and Astronomy at USC, is a leading figure in materials science. With over two decades of experience, Dr. Vashishta has been instrumental in advancing our understanding of materials under extreme conditions and leveraging artificial intelligence (AI) for materials discovery.

Research Focus and Interdisciplinary Approach


Dr. Vashishta’s research endeavors are rooted in the advancement of materials science through state-of-the-art computational and experimental methodologies. “Our focus lies in harnessing AI-guided simulations to delve into the behaviors of materials under extreme conditions,” Dr. Vashishta explains. This interdisciplinary pursuit seamlessly integrates quantum simulation, neutron-scattering, and machine learning techniques, aiming to unveil the fundamental mechanisms governing intricate materials phenomena.

 

Central to Dr. Vashishta’s research is the exploration of AI’s potential in scrutinizing materials for carbon sequestration. Understanding the urgency of curbing CO₂ emissions to mitigate global warming, his investigations encompass a spectrum of CO₂ storage methods. These range from localized initiatives to expansive regional strategies, with one notable avenue being the injection of captured CO₂ into geological formations. Such formations, including depleted oil and gas reservoirs, unmineable coal beds, and saline aquifers, hold the promise of sequestering substantial amounts of CO₂—up to 22,000 Giga Tons in North America alone.

Approach to Sustainable Energy Solutions

 

In addition to Dr. Vashishta’s work in carbon sequestration, he is tackling the urgent need for sustainable energy solutions in the face of global challenges. To address this need, his research focuses on advancing technologies for energy independence, including drop-in fuels from sunlight and air, green ammonia production, and on-demand hydrogen production. By integrating state-of-the-art simulation and experimental techniques, Dr. Vashishta aims to identify key atomistic mechanisms underlying these sustainable fuel production technologies, paving the way for further improvements.

Next Goals and Future Directions

 

Looking ahead, Dr. Vashishta and his team are digging deeper into understanding CO₂ mineralization reactions and stress corrosion cracking mechanisms in silicate minerals. By combining AI-guided multiscale simulations with experimental data, they aim to gain fundamental insights into the mechanisms governing CO₂ storage and containment. Additionally, their research on hydrogen diffusion through polymeric systems holds promise for enhancing the safety and efficiency of hydrogen storage tanks.
