Area: Laser/Arc-based additive manufacturing (AM), Metals, In-situ monitoring and control, AI for manufacturing, Physics AI, and Digital twin.
Vision: We explore novel manufacturing technologies, in-situ X-ray/sensor characterization, automation system, and artificial intelligence (AI) technologies to accelerate the additive/advanced manufacturing process and print advanced metallic materials. These innovations will help understand fundamental melt pool physics of laser/arc-based AM that lead to defects and use that understanding to build predictive models that can monitor, diagnose, and eventually control the manufacturing process in real time.
The main research includes (1) High-speed in-situ sensing/X-ray characterization for laser additive manufacturing; (2) AM in-situ alloying physics and defect formation; (3) Digital twin and AI foundation models for robot arm-based AM materials deposition; and (4) Real-time control of melt pool physics and part-scale quality assurance.
University: UL Lafayette is designated by Carnegie R1 University – “Doctoral University - Very High Research Activity” (total 137 in US as of 2021). The largest enrollment university within the nine-campus University of Louisiana System. The College of Engineering has over 1600 students, and offers B.S., M.S., and Ph.D. degrees in all engineering departments. ME department is the largest department in the College, with focus areas including renewable energy, manufacturing, robotics, materials and biomedical engineering.
Lafayette: Lafayette, LA is an exciting community within Louisiana's beautiful Cajun Country. It serves as the energy, manufacturing, financial, and medical center for South-Central Louisiana. Lafayette is located midway between New Orleans and Houston and is the heart of Louisiana's Cajun region, and is one of Louisiana's fastest-growing metropolitan areas.
