Joel Donald Brock is a Professor in the Department of Applied Physics at Cornell University's College of Engineering. He joined the Cornell faculty in 1989 after completing a postdoctoral research associate position at the Massachusetts Institute of Technology. Brock serves as Director of the Cornell High Energy Synchrotron Source (CHESS) and is affiliated with the Cornell Center for Materials Research (CCMR) and the Energy Materials Center at Cornell (emc2).
His research focuses on utilizing advanced synchrotron-based x-ray techniques to study material structures across atomic to nanoscale dimensions. Key areas include pulsed laser deposition of complex oxide thin films, development of next-generation x-ray sources (XFELs and ERLs), and structural analysis of materials for energy conversion processes. His work bridges fundamental physics with applications in renewable energy technologies.
Brock's research demonstrates significant impact across multiple domains:
- Developed time-resolved x-ray structural measurements to test growth models for complex oxide thin films
- Investigated structure-function relationships in photocatalytically active perovskite systems like SrTiO3
- Pioneered research on coherent x-ray beams for atomic-scale structural measurements
- Advanced understanding of oxygen evolution/reduction reactions critical for energy storage
His scientific recognition includes:
- NSF Young Investigator Award (1992)
- Multiple College of Engineering Teaching Awards (1996, 1999)
- College of Engineering Advising Award (2007)
- James M. and Marsha D. McCormick Advising Award (2010)
Brock maintains active collaborations across Cornell's research ecosystem, particularly with the Abruña group for electrochemical studies complementing structural research. His leadership extends to directing major university facilities and serving in professional societies including the American Physical Society (Fellow), Materials Research Society, and American Crystallography Association. His work continues to drive innovation in synchrotron science and materials engineering.
