Dr. Vijaykumar Varma, Ph.D.

I use fluid flow, chemistry, and machine learning to discover new materials quickly at Process Modelling, Automation and Robotisation (PROMAR) Group, Materials Research and Technology (MRT) Department, Luxembourg Institute of Science and Technology, Luxembourg-4422.

I am dedicated to advancing materials science as a Research and Technology Scientist (PI) specializing in microfluidics, droplets, and accelerated materials discovery (AMD). My work focuses on clean energy, flow synthesis, machine learning, sustainability, and thermal management. I'm passionate about innovation and its societal impact. My research spans lab-on-a-chip tech, PGM-less catalysts, composites, automation, metal alloys, energy harvesting, and green cooling. My expertise in fluid physics, microfluidics, and materials science has driven progress in flow chemistry-based AMD, droplet microfluidics, lab-on-a-chip tech, green cooling, and multiphysics simulations. I'm committed to pushing the boundaries of my research field to bring Luxembourg to the forefront of AMD research.
