Hello! Welcome to my webspace. I am a mathematician and an engineer. I am currently with the Department of Mathematics, State University of New York, at Plattsburgh. You can find my faculty profile here.
As my education and scholarship can attest, I have broad interests and tend to be transdisciplinary in my problem solving approach. My research interests in pure mathematics are primarily on questions in number theory. I am motivated by problems with an analytical flavor that have a rich algebraic and topological structure, and these usually tend to come from number theory. I also work on problems in linear algebra and matrix theory, and applied problems in computer science and engineering. I am interested in collaborating with people from academia, government and industry.
Below you will find some of my published and unpublished work, and presentations. Although I am quite introverted, I love collaborating with people! So, if you are interested in collaborating on any of the areas mentioned above please email me.
