| SAVING VIRTUAL LIVES WITH NANOBOTS GOAL 
              OF UH-LED PROJECT Computer Science Student to Compete in World Semifinals of Microsoft 
              Competition
  HOUSTON, May 11, 2005 – Building and controlling a team 
              of nanobots to seek and destroy infected tissue within a simulated 
              terminally ill patient, a University of Houston computer science 
              student and his teammate have advanced to the 2005 Microsoft Imagine 
              Cup world semifinals.  With two consecutive wins so far, Jonathan Dowdall, a UH graduate 
              student, and Mike Hall, his collaborator, have advanced to round 
              three of four in the visual gaming category with their Team ContAInment, 
              the “AI” capitalized to represent artificial intelligence. 
              An annual competition, the Microsoft Imagine Cup challenges participants 
              to excel in one of nine IT-related categories and is designed to 
              recognize students who demonstrate excellence in a diverse range 
              of technical and artistic pursuits. According to Microsoft, entries 
              are expected to address the competition theme to “imagine 
              a world where technology dissolves the boundaries between us.” 
             Out of about 2,000 participants in the world qualifying round March 
              15, Dowdall and Hall tied with eight others for first place, with 
              Team ContAInment being the only U.S. team in that top group. In 
              the national elimination round April 15, they were the top-scoring 
              team in their division. Now, advancing to the third of four rounds, 
              they will compete in the world semifinals May 15. The first two 
              rounds of competition took place online, as will the third, which 
              will narrow the playing field to six teams that will travel to Japan 
              July 27 to compete in the world finals for a grand prize of $8,000. 
             As visual gaming participants, Team ContAInment had to write an 
              algorithm to build and control a team of nanobots within the simulated 
              human body of a terminally ill patient. The nanobots are injected 
              into the blood stream to locate and collect infected tissue. While 
              attempting to deliver medicine to these sites, the nanobots are 
              attacked by white blood cells in the patient’s immune system. 
              For each round of competition, Microsoft adds another challenge, 
              such as a virus that attacks the nanobots.  “The visual gaming challenge is actually a logistics problem 
              that you are solving, and path planning is a big part of it,” 
              Dowdall said. “The strategy involves a collaborative multi-agent 
              programming system of nanobots, and you must give them intelligence 
              – the algorithm – so they know how to react in their 
              environment.” 
 To put it very simply, a computer program written by Team ContAInment 
              tells the nanobots to move up, down, left or right or to follow 
              any other variety of instructions in reaction to what they encounter 
              in the simulated environment.
 As head software developer for Associate Professor Ioannis Pavlidis’ 
              Computational Physiology Laboratory at UH, Dowdall is well prepared 
              for this challenge. Pavlidis has gained a reputation for his work 
              in medical imaging, bioinformatics, robotics, computational biomedicine 
              and biometrics that have various medical applications. Being part 
              of this research group has given Dowdall a solid background in applying 
              computer science to medicine.  “Projects like this where students are given an opportunity 
              to harness their imaginations often provide the type of forum where 
              ideas are born,” said John Bear, dean of the UH College of 
              Natural Sciences and Mathematics. “It’s great to see 
              ingenuity of this caliber receiving worldwide recognition.”
