In capacity as Professor of Mathematics at Fudan University?I'm writing to recommend Mr. Wang?Gesintosyour PhD program in Computer Science. I have known Mr. Wang since his sophomore year of college?and have acted as his thesis advisor and mentor. In my experience?he is a gifted and diligent student?and an admirably hard worker.

Wang is an impressive student because he has been forced to overcome the significant challenge of a serious illneduring his freshman year. When I first met Wang in my Discrete Math class?he did not appear to be anything special to me. While his exam scores were good?they were not as high as I would now expect of him. What I didn't know then was that due to his illness?Wang was attempting to take all of the difficult early mathematics courses at one time?including Discrete Mathematics?Advanced Mathematics?Linear Algebra?and Possibilities. While most students found preparing for just one set of these exams difficult?Wang was overwhelmed by four of them. But in the end?he achieved an impressive score on the final exam?which made me conscious of his unusual determination he demonstrates when confronting difficult challenges.

Mr. Wang and I have often talked about a variety of mathematics and computer science concepts and problems. During these discussions?I always found him to be delightfully intelligent. Not only does he quickly understand the concepts and problems presented to him?he is able to analyze these problems and present solutions. But perhaps most important is that Wang's thinking is intensely rigorous. When looking at any question?he carefully scrutinizes it and if he finds any uncertain issues?he clears them up immediately. I believe this kind of thought is essential to become an excellent computer programmer.

Serving as his thesis advisor?I had a first-hand opportunity to observe the way in which Wang's mind works. In his senor thesis?Mr. Wang mainly discussed two challenging questions in regards to″ANN″. In our books in China?knowledge of ANN and its uses are very rare. Few people in China have studied this topic and consequently?the materials that are available on ANN are limited. Working on this difficult project?not only did Mr. Wang rise to the challenge?but he went above and beyond the call of duty to analyze his secondary sources and test them for accuracy in practice. In this way?he found mistakes in the book that we use. His diligence and hard work made me extremely proud of him.
