## Biography

Prior to joining the U.S. Army Research Laboratory, I have held faculty positions. I was an associate professor at TOBB University of Economics and Technology, Ankara, Turkey. I was an assistant professor at Louisiana State University (LSU) in the Department of Mathematics and in the Center for Computation & Technology. After I left LSU, I continued to be a visiting assistant professor. I was also an adjunct research assistant professor at The University of New Mexico, in the Department of Mathematics and Statistics. My research has been funded by National Science Foundation, European Commission Marie Curie Program, and Scientific and Technological Research Council of Turkey.

I held two postdoctoral positions. My first postdoc was at California Institute of Technology in the Department of Computing + Mathematical Sciences in the area of computer graphics with a focus on digital geometry processing in the Multi-Res Modeling Group. My second postdoc was at The University of Texas at Austin in the The Institute for Computational Engineering and Sciences in the area of geosciences with a focus on robust preconditioning in The Computational Hydraulics Group and The Center for Subsurface Modeling.

I received my Ph.D. degree in Mathematics from University of
California, San Diego. I received my M.S. degree in Mathematics from
University of California, Irvine. I received a double major
B.S. degree in Mathematics and a B.S. degree in Science Education,
Mathematics Teaching from Middle East Technical University, Ankara,
Turkey.
