Costas P. Grigoropoulos received his Diploma Degrees in Naval Architecture and Marine Engineering (1978), and in Mechanical Engineering (1980) from the National Technical University of Athens, Greece. He holds a M.Sc. degree (1983), and a Ph.D. (1986), both in Mechanical Engineering from Columbia University. He joined the faculty of the Department of Mechanical Engineering at the University of California at Berkeley as an Assistant Professor in 1990, after serving as an Assistant Professor of Mechanical Engineering at the University of Washington from 1986-1990. He was promoted to Associate Professor in July 1993 and to Professor in Mechanical Engineering in July 1997. He holds the A. Martin Berlin Chair in Mechanical Engineering. He has conducted research at the Xerox Mechanical Engineering Sciences Laboratory, the IBM Almaden Research Center and the Institute of Electronic Structure and Laser, FORTH, Greece. He is Faculty Staff Scientist with the Environmental Energy Technologies Division of the Lawrence Berkeley National Laboratory.             Grigoropoulos’ current research interests are in micro/nano engineering, laser materials processing and micro/nano-machining, fabrication of flexible electronics and energy conversion devices, characterization of micro/nanofluidic transport and laser interactions with biological materials.             Grigoropoulos has taught courses in heat transfer, thermodynamics, fluid mechanics, laboratory instrumentation and experimentation, laser processing and diagnostics at both the Undergraduate and Graduate levels. He has guided 43 doctoral and 5 MSc students to completion and has advised 32 post-doctoral researchers and 32 visiting scholars. He has published more than 325 research articles in archival Journals, 17 Chapters in technical review books and 9 U.S. patents. He has also published the books *Transport in Laser Microfabrication*, Cambridge University Press (2009) and *Hierarchical Nanostructures for Energy Devices*, RSC Publishing (2014). He was a Miller Professor for basic research in science in 1999, a visiting Professor at ETH Zurich in 2000 and 2009 and a visiting Professor in Johannes Kepler University, Linz, Austria in 2008. He is a Fellow of ASME and SPIE, and recipient of the ASME Heat Transfer Memorial Award (2007) and Hawkins Lecturer Purdue University (2018). He was awarded an Honorary Doctorate and Gold Medal form the National Technical University of Athens (2022). He served as Editor of the *International Journal of Heat and Mass Transfer* from 2010 to 2022.
