I am Professor of Mathematics at the George Washington University where I teach a wide range of advanced and introductory courses. My research areas are computable model theory and computable algebra, computability theory, and theoretical computer science. National Science Foundation has been supporting my research via DMS grants 1202328, 0904101, 0704256 and 0502499. I am involved in research collaboration in computability with Russia/Kazakhstan and Bulgaria. I spent fall 2014 at the Kurt Gödel Research Center for Mathematical Logic of the University of Vienna. I gave a plenary talk at MAA Meeting at Bowie State University, Nov. 7-8, 2014. My book, co-edited with A. Eskandarian and J. Chubb,  Logic and Algebraic Structure in Quantum Computing, Cambridge University Press, appeared in March 2016.

I was a co-organizer of the Special Session on Computable Structure Theory at the AMS Meeting in March 7-8, 2015 in Washington, and a co-organizer of the joint AMS/ASL Special Session on Logic and Probability at the Joint Mathematics Meetings in January 2014 in Baltimore. I served on the Program Committee for 2016 Computability in Europe meeting in Paris, June 27-July 1, and served on the Program Committee for the 2013 European Summer Meeting in Evora, Portugal. I chaired the Organizing Committee for the ASL 2010 North American Annual Meeting at GW.

I am a co-director of the GW Center for Quantum Computing, Information, Logic and Topology. I organize Washington Area Logic Seminar at GW, and  also co-organize the bi-annual meetings Knots in Washington, the latest ones are XLII during April 29-May 1, 2016XLI during December 4-6, 2015, XL in March 2015, XXXVIII in May 2014, and XXXVII in January 2014. In Spring 2015 and Fall 2015, I organized GW Math Colloquium.
