Monte Carlo simulation of 2D grain growth.

I am currently an assistant professor in the Department of Mechanical Engineering at Bogazici University. My current research is on the evolution of metallic microstructures, the measurement and prediction of grain boundary properties, the representation of material textures, and certain questions of statistical topology.

Before my current appointment, I worked as a Lawrence Fellow at Lawrence Livermore National Laboratory from September 2011 to April 2013. Collaborating with Mukul Kumar and others, we developed a Monte Carlo grain growth code that used a realistic grain boundary energy function to calculate the driving force for boundary motion. One of the resulting microstructures for a simulated copper sample appears to the right.

From September 2009 to July 2011 I was a member of the School of Mathematics at the Institute for Advanced Study, where I worked with Robert D. MacPherson and several other researchers to use statistical topology for the analysis of materials microstructures. We developed the notion of a swatch as a compact representation of the grain boundary network topology, roughly consisting of a canonical labeling like the one to the left.

I received my PhD in June 2009 from the Department of Materials Science and Engineering at the Massachusetts Institute of Technology, where my adviser was Christopher A. Schuh. My dissertation proposed a representation of orientation distributions as a harmonic expansion on the space of normalized quaternions, useful for the manipulation and visualization of material textures.
