John Chuang

John Chuang is a Professor in the School of Information at UC Berkeley, with an affiliate appointment in the Department of EECS. His research interests are in bio-sensory computing (brainwave authentication, human factors in wearable computing) and information economics and policy (network economics, peer production, security and privacy). The Chuang Sirbu Scaling Law is named for his work on scaling properties of multicast trees.

He received his Ph.D. in Engineering and Public Policy from Carnegie Mellon University, M.S. in Electrical Engineering from Stanford University, and graduated summa cum laude in Electrical Engineering from the University of Southern California.

Prof. Chuang co-created BoxBabble, an ingredient-based search tool serving consumers with food allergies and sensitivities. He designed the registerfile (and won the chip logo design contest) for the MIPS R10000 microprocessor, now in the collection of the National Museum of American History at the Smithsonian Institute.
