Research

My area of research is Algebraic Logic. Mathematical logic is an important area in mathematics primarily because it provides the foundations for all of mathematics, a framework and the rules of inference that are used universally in all areas of Mathematics. Logic is applicable, however, to a wide range of disciplines extending past the natural sciences and spanning all the way to philosophy, law and psychology. Logical inferences in different disciplines naturally abide different laws, thus giving rise to different (but similar) logical systems. These logical systems can in turn be studied and compared using precise language and analysis, something that the discipline of mathematics naturally possesses. In my research I use tools from Abstract Algebra to study and compare different logical formalisms, establish general facts about them and bring to the surface differentiating features.
