Hattan Tawifiq

Visiting Professor
Office: Monroe #218
Phone: 994-0606
Professor Hattan Tawfiq of King Fahd University of Petroleum and Minerals in Dhahran, Saudi Arabia, is currently visiting our department for this academic year. His research interests are in the numerical analysis and solution of partial differential equations with applications to flow in porous media. Professor Muli Gupta is the host for his visit.

Mark Kidwell

Visiting Professor
Office: Monroe #263
Phone: 994-6890
Research Interests: Topology, Knot Theory, Dynamical Systems
Professor Kidwell received a B.A. in mathematics from the University of Virginia in 1970 and a Ph.D. in mathematics from Yale University in 1976. His thesis, written under the direction of Professor Ronnie Lee, concerned two-variable Alexander polynomials of two-component links. He has taught at Amherst College and, for nearly 30 years, at the U.S. Naval Academy. Previous sabbaticals have taken him to Columbia University, Liverpool University, GWU, and Lafayette College. He has pursued research in low-dimensional topology and dynamical systems. He has served as an outside examiner for ten GWU thesis defenses and is a frequent participant in Knots in Washington conferences.

Shuqin Zhang:

Visiting Professor
Office: Monroe #261
Phone: 994-0617
Research Interests: Fractional Differential Equations
Professor Shuqin Zhang of China University of Mining and Technology is visiting the Mathematics Department of George Washington University from September 1, 2011 to August 31, 2012. Prof. Zhang specializes in fractional differential equations. Her visit is sponsored by the State Scholarship Fund of China Scholarship Council. Her local host is Xiaofeng Ren.

Inmaculada C. Sorribes:
Professor is an exchange student from the Autonoma University of Madrid (Spain). Her current research focuses on the mathematical study of partial differential equations that describe the evolution of brain tumors, also called glioblastoma. In Spain, Inmaculada has been working on numerical study of this model. At GW, under the supervision of Professors Gualdani and Ren, Inmaculada is working on an analytical study of the go-or-grow model in two different phenotypes or tumor cells.


Marithania Silvero Casanova:
Visiting studentfrom University of Sevilla, Spain, is hosted by Professor Jozef Przytycki.

William de la Cruz;

Visiting Doctoral Student
Office: Monroe #223
Phone: 994-0346
Research Interests: computational complexity, quantum computing and quantum information, computer vision and simulation, and second order logic.
William de la Cruz is prof. Harizanov's visitor in Fall 2011. He is a doctoral student from the Center of Research and Advanced Studies of IPN, Mexico City. His visit to GWU is supported by the National Council of Science and Technology at Mexico City. William de la Cruz received his B.Sc. degree from the University State Juarez of Tabasco, Mexico in 2004, and his M.Sc. degree in computer science from the Center of Research and Advanced Studies of IPN, Mexico City in 2007.
