Same group as above only Zhengzheng is taking the picture and I'm in it!
Haiyan, myself and Patti with Yangzi in the front. We are in Haiyan, John and Yangzi's wonderfully warm home, getting ready to go to Lai Lai's for dinner. Yangzi is an amazing young girl. She just passed her grade 6 conservatory piano exam, she did all the drawings on the wall behind us (you may not be able to see without enlarging, but the drawings are amazingly well done) and she is now taking violin lessons. Totally awesome!!!!!
Myself, Marina, Julia and Jarka sitting in front of the gazebo in my backyard. It was one of those lucky days when we all just happened to be there together. Julia was finishing her Master's thesis, Marina had just finished her comprehensives. Jarka and I were finishing our paper #2 which subsequently has appeared as "Portfolio selection and transactions costs", Computational Optimization and Applications, 24 (2003) 1, 95-116. [Summer, 2001]
Dr. Lise Arseneau and myself at her graduation. 
Marina and her Dad having lunch with me in my back yard. Her Dad, Anatolli, is a Professor of Mathematics in Minsk. Patti made those yummy looking desserts we are about to indulge in. [Summer, 2002]
Patti, me, Peter and Marina. Marina had us for dinner (scrumptous!)[Summer, 2002]

Zhenpeng Qu will begin her doctoral studies with me in Fall, 2004. When she got her formal acceptance, we celebrated by her taking me to lunch at Lai Lai's. Great food and great conversation!
In 1983, the government of the People's Republic of China invited me to visit China and lecture in Beijing, Wuhan and Shanghai. I went to Beijing in June, 1984. Ruo Yang Tan was my guide in Beijing and he took me everywhere! We had many long discussions about mathematics and I was so impressed with his abilities that I invited him to come to Waterloo and study for his Doctorate with me. He became Dr. Tan in 1991.
