Background

Sourabh Saha began working at Georgia Tech in August 2019. Prior, Saha was a Research Engineer at the Lawrence Livermore National Laboratory, where he was the principal investigator for a Laboratory Directed Research and Development project on nanoscale additive manufacturing. His current research is in scalable and affordable manufacturing of micro and nanoscale 3D structures with the goal of breaking traditional engineering tradeoffs through process and system innovations.

Research

Saha leads the Scalable Technologies for Advanced Manufacturing (STEAM) research group, which is attacking the scalability problem of advanced manufacturing. Manufacturing is the science and engineering of making products to specifications. Advanced manufacturing refers to improvements in manufacturing processes and products using innovative technologies. These improvements could be in the form of finer quality, higher production rates, higher versatility, lower cost, or a larger material set. For many emerging advanced manufacturing processes, there are significant barriers that prevent delivering these improvements on the scales necessary to make a tangible real-world impact. The STEAM lab aims to overcome these barriers through the generation of new manufacturing capabilities.

The current focus of the group is on manufacturing complex 3D structures with single-digit micrometer and nanoscale features in a variety of materials including polymers, metals, ceramics, and composites. Such 3D structures can enable quantum information transfer in integrated quantum photonics devices, fuel capsules for inertial fusion energy, high-sensitivity chemical sensors, fast-charging batteries, miniaturized optics such as lenses mounted on optical fibers, synthetic biomaterials for cell therapies, and micro-robotics for drug delivery. The group’s approach involves understanding the fundamental manufacturing science underlying the energy-matter interactions that generate micro and nanoscale features and applying this knowledge to engineer processes, techniques, and tools that scale up manufacturing. Work in the group is multidisciplinary drawing from fields such as additive manufacturing, ultrafast optics, multi-photon lithography, laser processing, polymerization chemistry & chemical reactions, applied mechanics, nucleation and crystallization, machine learning, and precision machine design.
