Dave Garth joined the Mathematics faculty in 2000 after completing his Ph.D. in Mathematics from Kansas State University.  His research interests lie in Number Theory in general, and in Pisot-Vijayaraghavan numbers in particular.  He teaches a wide range of courses in the math department, with some of his favorites being Calculus III, College Geometry, Mathematics for Elementary School Teachers, Complex Variables, and of course, Number Theory.  He also enjoys working with undergraduates on research projects.  Check out the personal website above for some samples of senior capstone projects he has supervised.  He is a member of the Mathematical Association of America.  He enjoys working at Truman for the emphasis on undergraduate education and the student mentoring opportunities.  One of his other interests is country music, which he considers to be not mutually exclusive with mathematics.  For one of his attempts to integrate the two, check out this link.
