Overview


Dr. Arpit Mishra is a Postdoctoral Associate in the Department of Mechanical Engineering and Materials Science at Duke University, USA. His research focuses on laser lithotripsy for urolithiasis treatment, combining both experimental and simulation approaches to investigate laser interactions with fluids, bubbles, and solid surfaces. He earned his PhD and M.S. in Mechanical Engineering from the Indian Institute of Technology, Kharagpur, where his dissertation centred on the dynamics of interacting cavitation bubbles. His international research experience includes fellowships as an ETH4D Visiting Researcher at ETH Zurich and a Raman Charpak Fellow at CEA/UGA Grenoble. Dr. Mishra's expertise extends to cryogenic engineering, hydrodynamic cavitation, and laser thermal safety. He has been recognized with several prestigious awards, including the Milton Van Dyke Award from the APS Division of Fluid Dynamics, the T.H.K. Frederking Space Cryogenic Workshop Student Scholarship, and the ETH4D Visiting Student Grant. His work has been featured in the 1st Traveling Gallery of Fluid Motion by the Cultural Programs of the National Academy of Sciences (CPNAS).

Ejecta-Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion.

Journal article Advanced science (Weinheim, Baden-Wurttemberg, Germany) · April 2026 Cavitation bubbles generated by laser absorption in liquids collapse violently, producing high-speed jets, toroidal bubbles, and shock waves that induce material erosion and object displacement. In laser lithotripsy, this phenomenon causes kidney stone mig ... Full text Cite
