It is my pleasure to give an unreserved excellent recommendation for Chao Wei Ou. I have known him and his work for almost 5 years as a Ph.D. student and postdoctoral staff at NPAC. Syracuse Ph.D. students are typically very successful and Chao Wei is in the top group of these. His thesis was very well regarded and involved essentially parallel algorithms and a major software implementation. More recently Chao Wei has broadened his skills through his involvement in many projects. In particular he has performed excellently in Financial Modeling on PC's, databases and the Internet. His work continues to be of high quality and I will be sorry to see him leave! Chao Wei is an excellent team player and writes quite well -- far above average for a typical Syracuse student from Asia. These general qualities combined with his superior technical skills would make him an excellent IBM employee.
