Welcome to the research webpage of Sirohiwal Lab! Our research aims to uncover how nature performs complex chemical transformations with remarkable precision and efficiency. We explore the intricate interplay between electrons, protons, and the dynamic protein environment in biological enzymes, especially, light-harvesting complexes and energy and signal transducing bioenergetic system. By combining multiscale modeling, quantum chemistry, and molecular simulations, we seek to understand fundamental bioenergetic processes and enable the rational design of biomimetic and engineered proteins for sustainable chemistry and beyond.
