Widodo Samyono


Status:
I have a Ph. D. degree in Computational and Applied Mathematics from the Department of Mathematics and Statistics at Old Dominion University, Norfolk, Virginia, and my advisor is Dr.  David E. Keyes, presently as Fu Foundation Professor of Applied Mathematics at Department of Applied Physics and Applied Mathematics, Columbia University, New York City, New York.


Research Interest:
I am interested in the fields of scientific computing, optimization, numerical analysis, mathematics in industry, and parallalel computing. Currently, I have concentrated my works on Partial Differential Equations, Mathematical Modelling for Multi Physics problems, PDE-contrained optimization, and parallel computing (domain decomposition methods).
