About the Instructor

I’m Bibhatsu Kuiri, a multidisciplinary researcher and educator with expertise in multiphysics simulation, material modeling, and AI-enhanced design automation. My work spans simulation-heavy domains such as photonic crystals, solid-state batteries, optical communication, supercapacitors, glassy systems, and sensors (check my google scholar page for more).

Over the years, I have used a range of tools and methodologies including COMSOL Multiphysics, Ansys, MATLAB, Python, and DFT software suites like VASP and Quantum ESPRESSO to design, optimize, and validate systems across physics and engineering domains. My experience with accelerated design workflows, especially using AI, machine learning, and data-driven approaches, has allowed me to solve complex engineering problems more efficiently, often integrating theoretical, computational, and experimental insights. In addition, I’ve developed several research tools and custom software from scratch for sensor design, simulation optimization, and automated analysis workflows. I have also taught nanophysics and multiphysics modeling to graduate students at IITs and other universities.
