Primary Investigator

Dr. Jim Valles, Ph.D.

Professor Valles does research in experimental condensed matter physics, in the areas of: superconductivity; electron correlation effects in disordered metals and nanostructures; and in using magnetic fields as a new tool for cell biology and biopolymerization. Professor Valles joined the faculty at Brown in 1992. Prior to this he was an Assistant Professor of Physics at the University of Oregon from 1989 to 1992 and a postdoctoral member of the technical staff at AT&T Bell Laboratories from 1987 to 1989. He received his Ph.D. from the University of Massachusetts in 1988 and his Bachelor of Arts from Dartmouth College in 1981. He is the recipient of an Alfred P. Sloan Foundation Fellowship.

Graduate

Hung Nguyen [2004-present]

Hung has spent some time doing biophysics here in the Valles lab, but as of 2007 he has been working on the superconducting side. He and Shawna are currently studying the effects of disorder on the transport in thin NHC films.

Shawna Hollen [2007-present]

Shawna joined the lab in May of 2007 and is currently working with Hung to determine the effects of disorder on the transport in thin NHC films. She has also worked with recently-graduated undergrad, Ryan Murphy, to systemize and idealize the fabrication of tunnel junctions on the NHC substrates.

Yongxing Guo [2003-2008]

Phrases and terms from Latin make up a large part of this terminology, and reading mathematical texts – especially more advanced ones – is made easier if one is equipped with knowledge of these terms in advance. We review below the Latin terms most commonly used in mathematics, and follow with a more extensive list of such terms and phrases as one may run into more rarely or in other contexts. The pronunciations given are not the “correct” Latin pronunciations, but instead reflect common usage in English speaking countries. Note that when Latin or other non-English words are used in writing, they should be italicized except where they are abbreviated as single letters. E.g., “His next remark was a non sequitur.” thesis (Brown only)

Undergraduate

Ryan Murphy

Ryan Murphy's work in the Valles Lab has evolved while an undergraduate at Brown and culminated in a senior thesis project on density of states measurements on nano-holed thin Pb films with normal metal/insulator/superconductor tunnel junctions which was conducted through the Summer of '07 and throughout the '07-'08 academic year. His favorite color is chartreuse (for the name), his favorite movie is The Spanish Prisoner, and his favorite book is Treasure Island. When not in the lab he enjoys long runs, listening to NPR news, making political jokes, and playing his violin. Ryan will be graduating from Brown with an Sc.B. in Physics in May and will join the Physics PhD program at Boston College beginning in the Fall of 2008. He can be reached for the next 6 years at ryan.murphy.7@bc.edu.
