Biography

Dr. Alexandre Tartakovsky is a scientist in the Computational Science and Mathematics Division at the Pacific Northwest National Laboratory.

The main focus of Tartakovsky's research is the theoretical and computational aspects of the modeling of flow and reactive transport in porous and fractured media under both saturated and unsaturated conditions. In Tartakovsky's research in the subsurface flow and transport phenomena, he pursues a multi-disciplinary approach and relies on methods and techniques used in hydrology, mathematics, computational physics, and chemical engineering.
