About Me

I have a passion for solving in-depth and challenging problems in (electro-)catalysis, reactor design and control. This passion stems from strong foundations that I developed during my Masters in Mechanical Engineering at University of Minnesota, PhD in Chemical Engineering at Karlsruhe Institute of Technology and Postdoctoral research in Electrochemical Energy Storage and Conversion at Imperial College London.
At UT, I am now leveraging those foundations to investigate and teach the fundamental physico-chemical phenomena across multiple scales that govern the performance and life of next-gen (electro-)chemical devices e.g. hydrogen fuel cells, electrolysers, batteries, that will help accelerate the energy transition.

We aim to develop a multi-scale understanding to reliably design and control next generation (electro)chemical technologies with special focus on hydrogen fuel cells and electrolysers and redox flow batteries. To do this, we use high-fidelity integrated model frameworks that start from nanomaterial surface models and go all the way up to process flowsheet models. We combine micro-kinetic reaction modelling, structural evolution modelling, continuum transport modelling and machine learning with tailor-made experiments to develop physics-based cognitive digital twins.

See this video from the 2022 EU Hydrogen Week in Brussels highlighting one of the main themes of our research.
