Profile Summary

I have a PhD in heat transfer and have taught graduate and undergraduate thermal sciences courses since 2001. I have extensive experience in laser-based thermal processesing, primarily in laser microfabrication. Specific experience includes laser ablation, laser micromachining, laser-induced forward transfer, and laser texturing. My laser background includes time-resolved studies of short pulse micromachining. I founded and manage the Laser Micromachining Laboratory at Southern Methodist University, in the Department of Mechanical Engineering.
