My primary areas of interests include- Algebraic geometry The factoriality of threefolds with isolated singularities, The speciality of linear systems through fat points on projective space, Rationality(uni-rationality, rationally connectedness) of nodal threefolds. - Some problems in Differential geometry

principle on a complete Riemannian manifold, The spectrum of
the Dirac operator on some spin (or spin- c) manifolds.
