Teaching Interests

Professor Saha’s teaching interests encompass core and advanced topics in mechanical engineering, with a focus on manufacturing science and engineering. He emphasizes the integration of fundamental principles with experimental and computational approaches at both undergraduate and graduate levels. His instructional approach seeks to develop critical thinking and problem-solving skills in students, fostering a deep understanding of multidisciplinary engineering concepts relevant to manufacturing.

Research Interests

Professor Saha’s research centers on solving 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. His research aims to overcome these barriers through the generation of new manufacturing capabilities. The research involves understanding the fundamental science underlying the energy-matter interactions that generate patterns and applying this knowledge to engineer processes, techniques, and tools that scale up manufacturing.
