Astha Sharma is a research fellow at the ACT-H2 program, School of Engineering at ANU. She grew up in India, where she experienced the impact of climate change first-hand, which motivated her to go into renewable energy research to work towards solving the problem. She is a Physicist and finds it closely tailored to her personality and is extremely passionate about applying physics to energy applications. She finished her PhD in direct solar hydrogen generation, from school of engineering, ANU in 2021. Her research interest focusses on developing renewable technologies as an efficient, clean, and cheaper route to hydrogen production. Her work focusses on material development, computational modelling to understand different system configuration and limitations and techno-economic analysis for large scale hydrogen generation applications.
