Associate Professor Kakalios has recently begun studies of granular media and complex systems, in addition to his ongoing research into the electronic and optical properties of amorphous semiconductors. The amorphous silicon research involves the fabrication and processing of thin film hydrogenated amorphous silicon, and studies of non-Gaussian 1/f noise, stretched exponential relaxation, thermal equilibration processes, random telegraph switching noise, thermoelectric effects and optical and infra-red spectroscopy. The work in granular materials began in 1993, and is summarized on this web page.

Kimberly Hill

Kimberly M. Hill made the inital discovery of a reversible axial segregation effect with Prof. Kakalios at Minnesota in 1993, received her M.S. in 1995 and her Ph.D. in 1997. She is presently a post-doctoral research associate with Dr. James Martin, studying the physics of colloids, at Sandia National Laboratory.

Michael Enz

As an undergraduate junior at the University of Minnesota, Michael started work on avalanche dynamics in the spring of 1996. He has written the avalanche simulations and is responsible for this web page.

Jim Koeppe

Jim compiled the systematic avalanche startification data during the summer after his freshman year. Throughout the following year he has taken data for the phase diagram and dabbled in other theories of segregation.
