Research interests: I am an algebraist, with interest in noncommutative rings and their categories of modules. Since 2005 my primary focus has been on a class of rings called "Leavitt path algebras".
Recent Articles:(much of this research is supported by a Simons Foundation Collaboration Grant in Mathematics)  "Extensions of simple modules over Leavitt path algebras (with F. Mantese, A. Tonolo), submitted.  "Leavitt path algebras: the first decade", Bulletin of Mathematical Sciences, to appear.  "Cohn path algebras have Invariant Basis Number" (with M. Kanuni), Communications in Algebra, to appear.  "The prime spectrum and primitive ideal space of a graph C*algebra" (with M. Tomforde), International J. Math, to appear.  "The Leavitt path algebras of generalized Cayley graphs" (with G. Aranda Pino), Mediterranean J. Math, to appear.  "A class of C*algebras that are prime but not primitive" (with M. Tomforde), Muenster J. Math., to appear.  "Leavitt path algebras of Cayley graphs arising from cyclic groups" (with B. Schoonmaker), Proceedings of the conference "Noncommutative rings and their applications, Lens, France, July 2013", American Mathematical Society Contemporary Mathematics Series, to appear.
