Research Interests:

Applications of coverings of the integers. Erdős’ minimum modulus problem. Fibonacci/Lucas numbers that are also Sierpiński/Riesel numbers. Goldbach’s conjecture for monic polynomials. Composite numbers that remain composite after any substitution (ditto for insertion) of a digit. Sierpiński and Riesel numbers that “likely” do not arise from coverings. Numbers of the form: kr2n+1, kr2n-1, and kr-2n. Factorization of x2+x.
