Igor Mezic’s research interests include the science and technology of energy efficiency dynamics, including building systems, micropower generation and power grids; dynamical systems theory of complex systems, including large-scale networked systems; mixing and separation in fluids across the scales with applications ranging from microfluidic phenomena to oceanographic flows; and nano- and micro-scale particle dynamics induced by dielectrophoresis and other electrokinetic phenomena, with applications to biotechnology. One application of his research is the optimization of energy efficiency in building systems through energy-smart design and control systems to help manage energy use. Understanding complex fluid flows and mixing is essential for any energy efficient process as fluid is often one means to transport energy (and often linked to comfort in systems such as buildings). Mezic has also established modeling techniques that enable design of efficient mixing in variety of settings and scales from the room or atmospheric level to micrometer sized flow channels.

Igor Mezic received an M.S. degree in Mechanical Engineering from the University of Rijeka, Croatia in 1990 and a Ph.D. in Applied Mathematics from the California Institute of Technology in 1994. Before coming to UC Santa Barbara in 1995, he was a Postdoctoral Research Fellow at the University of Warwick, UK. From 2000-2001, he also served as an Associate Professor in the Division of Engineering and Applied Science at Harvard University. Mezic was awarded the National Science Foundation CAREER Award for research on "Nonlinear Dynamics and Control from Microscale to Macroscale" (1999), as well as a Sloan Foundation Fellowship in Mathematics (1999) and the Axelby Outstanding Paper Award (2000). For his technology contributions, he was awarded the United Technologies Senior Vice President's Special Award (2007), and gave a number of plenary lectures at conferences in his field. In addition to contributing his time and expertise to a significant number journals, panels, workshops, and conferences, Mezic has over 60 journal publications, has edited or co-written three books and has received numerous grants and industrial gifts.
