IIT Bombay · Department of Mechanical Engineering
The Laser Advanced Materials Processing Laboratory studies how laser light interacts with matter — harnessing it for micro- and nano-scale fabrication, surface engineering, and next-generation manufacturing processes, through tightly coupled experiments and multiphysics modelling.
Femtosecond to nanosecond laser machining, texturing, and structuring of metals, glass, semiconductors, and composites at the micro and nano scale.
Fundamental studies of ablation, plasma formation, and ultrafast phenomena that govern how laser energy is absorbed and removes material.
Computational models of manufacturing processes — laser ablation, laser-assisted machining, additive manufacturing, and EDM — validated against experiments.
Data-driven and machine-learning approaches, in-situ monitoring, and process maps to improve precision, quality, and efficiency across laser manufacturing processes.

Prof. Marla leads the Laser Advanced Materials Processing (LAMP) Lab. His research spans laser-based micro- and nano-fabrication, the fundamentals of laser–matter interaction, and multiphysics modelling of manufacturing processes. He earned his B.Tech. and Ph.D. from IIT Bombay and held postdoctoral positions at the University of Illinois at Urbana-Champaign and the Technical University of Denmark before joining the faculty in 2017.
He currently serves as the Vice-Chairperson of the Student Wellness Centre, and Professor In-Charge of the Flourishing Hub, NSS IIT Bombay, and Group for Rural Activities.
