Welcome to Dr. Sigal Gottlieb’s Research Website at UMass Dartmouth.

I am a computational mathematician whose interests lie primarily in the development of numerical algorithms for the simulation of hyperbolic PDEs. I am best known for my research in strong stability preserving (SSP) time discretizations. However, I am also interested in spatial discretization techniques such as spectral and pseudospectral methods and WENO methods. Recently, I have been developing reduced basis methods in a collocation context.

Please visit Research and Publications for a more in depth look at my research.
