"Our Friend Forever!"

We lost our dear friend Paul E. Wray in November 2002.  I was one of the very lucky people who had the opportunity to know him closely.  Tears could not be enough to express the sorrow of loosing him and the words would not be enough to express my respect and love for him.  He was a great friend and a great scientist. He will live forever in my heart and so will his professional qualifications in this page.
