I am an applied mathematician/statistician, interested in medical research. I received my PhD in mathematics with a focus on probability theory from Southern Illinois University Carbondale. I have two master’s degrees: MS in statistics from West Virginia University and MS in mathematics from Bilkent University. I earned my BS in mathematics and computer science at Cankaya University.

Before I joined the Department of Mathematics at Siena College, I held positions in the Faculty of Medicine at Mugla Sitki Kocman University, Mathematics and Statistics Department at Vassar College, Mathematics Department at Southern Illinois University, and Cancer Institute at West Virginia University.

Current Research

I do research in various fields of biomathematics and biostatistics. My current studies concentrate on biomarker studies in clinical medicine, genomic and microbiome data analysis, and mathematical modeling of infectious diseases.

I work on a wide range of research projects in mathematical and medical sciences and participate in collaborative research activities with many researchers from different disciplines. My current collaborative research interests are in the areas of neurological disorders and orthopedic surgery. I also have been involved in research in dermatology, cardiac surgery, pathology, radiology, forensic medicine, gastroenterology, ophthalmology, and anesthesiology.

Undergraduate Research Opportunities. Many of my research projects have aspects that are suitable for undergraduate research. I am always very glad to talk with students about the possibility of research projects in applied mathematics and statistics. I'm currently looking for students to work on my projects about the transmission dynamics of vector-borne diseases. If you've completed Calculus II, and want to have research experience, come and see me. R, Python, or MATLAB experience is preferable. I will teach the essential mathematics and statistics for these projects.
