Troy Butler recently joined the department as an Assistant Professor.
Currently, Troy's research is supported by grants from the NSF and DOE.

From 2012-2013, Troy was a research scientist at Colorado State
University (CSU) working in Dr. Don Estep's research group on
uncertainty quantification. From 2009-2012, Troy began his postdoctoral
work an ICES Postdoctoral Research Fellow and was promoted to a Research
Associate in the Computational Hydraulics Group directed by Dr. Clint
Dawson within the Institute for Computational Engineering and Sciences
(ICES) at The University of Texas at Austin.

Troy's current projects include developing and applying novel
uncertainty quantification techniques to a variety of real-world
problems using real data involving storm surge from hurricanes and
tropical cyclones in the Gulf of Mexico, subsurface contaminant spread
with a model problem based on a chromium plume beneath Los Alamos
National Laboratory, and detecting damage in vibrating beams by passive
observation networks.
