My research is in Universal Algebra. I am currently studying clonoids. A clonoid from an algebra A to an algebra B is a set of functions from finite powers of A into B that are closed first with respect to composition with term functions of A and next with respect to composition with term functions on B. Clonoids have been used in studying equational theories of finite algebras, classifying expansions of algebras, and investigating the computational complexity of Promise Constraint Satisfaction Problems. In the below preprint, Clonoids between modules, we study clonoids whose source and target are abelian Mal'cev algebras (algebras that are polynomially equivalent to modules). Current work connects clonoids to central extensions. In particular, we can understand the structure of a 2-nilpotent Mal'cev algebra by understanding two abelian algebras and a clonoid from one to the other. I am currently working on determining the computational complexity of the Subpower Membership Problem for 2-nilpotent Mal'cev algebras, which asks for a fixed algebra, given elements in some power of the algebra, determine if another given element is in the subalgebra generated by these elements.
