    • Complex and Hypercomplex Analysis
      Complex Analysis is a classical branch of mathematics, having its roots in late 18th and early 19th centuries, which investigates functions of one and several complex variables. It has applications in many branches of mathematics, including Number Theory and Applied Mathematics, as well as in physics, including Hydrodynamics, Thermodynamics, Electrical Engineering, and Quantum Physics. Clifford Analysis is the study of Dirac and Dirac type operators in Analysis and Geometry, together with their applications. In 3 and 4 dimensions Clifford Analysis is referred to as Quaternionic Analysis. Furthermore, methods and tools of Clifford Analysis are extended to the field of Hypercomplex Analysis.

    • Algebraic Computational Methods in Geometric and Physics PDEs
      In recent years, techniques from computational algebra have become important to render effective general results in the theory of Partial Differential Equations. My research is following the work of D.C. Struppa, I. Sabadini, F. Colombo, F. Sommen, etc., authors which have shown how these tools can be used to discover and identify important properties of several systems of interest, such as the Cauchy-Fueter, the Mosil-Theodorescu, the Maxwell, the Proca system, as well as the systems which naturally arise from the work of the Belgian school of Brackx, Delanghe and Sommen.

    • Foundations of Geometry
      I am interested mostly in the Hilbertian axiomatic approach to Geometry. Far from being an expert in this field, I am studying especially the constructions of Euclidean and non-Euclidean geometries using purely geometric axioms, without using numbers, distances, and/or continuity properties.

    • Mathematics Education
      My interests lie in methodological aspects of introducing research ideas and modern results in Mathematics and Physics to undergraduate students and future teachers. My goal is to raise scientific awareness and interest among college and university students, and to prepare them for active research.
