Current Members

Walker D. Greg Walker, Associate Professor (Mechanical Engineering)
Prof. Walker started at Vanderbilt in 2001 and has built a research group to study small-scale energy transport phenomena and novel heat flux measurement techniques. He is not nearly as smart as he looks.
Sadie Gollub Sarah (Sadie) Gollub, Ph.D. student (Materials Science)
Sadie is studying how radiation interacts with ceramic materials by studying the luminescent properties of irradiated powders. In particular she fabricates thermographic phosphors and measures the spectroscopic changes induced by various radiation exposures.
Matt Gerboth Matt Gerboth, Ph.D. student (Materials Science)
Matt is studying thermal transport at materials interfaces mediated by van Der Waals interactions using molecular dynamics and quantum transport simulations
Casey 
Brock Casey Brock, M.S. student (ME)
Casey is generating algorithms for the automated generation of pseudo potentials that are suitable for DFT calculations with defects and non-[erfect crystal configurations.
Izany Md Sallih Izany Md Sallih, Undergraduate (ME)
Izany is optimizing pseudopotentials of lithium and fluorine for use in LiF with defects.
Liza MacPherson Liza MacPherson, High-school researcher
Liza is building a demonstration of phosphor measurement using the Arduino microcontroller
Zack Coppens Zack Coppens, Ph.D. student (ME)
Zack returned from Sandia National Lab to pursue his Ph.D. in metamaterials and plasmonics. He is really only an honorary member of our lab.

Nicholas (Nick) Roberts, Ph.D. (Mechanical Engineering, July 2010)
Nick is now a postdoctoral fellow at UTK, but you can find him at the Center for Nanophase Materials Science at Oak Ridge Natioanl Lab. For his PhD project, he used computational techniques to calculate thermal properties of solid-state energy conversion devices. He also uses these methods to investigate thermal rectification effects in nanoscaled asymmetric interfaces.
