My research interests are mainly in Partial Differential Equations (PDE) and Numerical Analysis of PDE. These include theoretical aspects of approximation theory, regularity theory and continuum mechanics. Please take a look at my Google Scholar, ORCID, ResearchGate and MathSciNet profiles for my pre-prints and publications (you can also see them listed below).
