My area of research interest is the spectral theory of linear operators and its application to the solution of problems in the mathematical physics and functional analysis. My recent research activity covers a broad area, including topics as far-off as high energy physics and numerical linear algebra. These include Numerical approximation of eigenvalues of self-adjoint operators Spectral theory of non-self-adjoint operators Non-trivial aspects of pseudospectral theory Spectral theory of supermembranes

I obtained my PhD degree in Mathematics from King's College London in 2001. Before arriving in Heriot-Watt University I spend a couple of years as a lecturer in the Universidad Simon Bolivar (Venezuela) and as a postdoctoral fellow in the University of Calgary (Canada). I have been staff here since 2005.
