Bill Gates, on day three of his college tour, listens Wednesday as MIT students present ideas ranging from how technology can help improve health care in poor countries to ways of getting more students involved in global issues.

Several of Bill Gates' meetings at MIT on Wednesday were held in a building that bears his name, in recognition of his contributions to the school.

As he does at each school he visits, Gates meets on Wednesday with MIT recipients of the Gates Millenium Scholarship, a foundation program that funds college educations for high-achieving minority students.

Gates walks with MIT Chancellor Phillip Clay on Wednesday as he heads out to speak to students on the final day of his three-state college tour.

Gates listens as second-year doctoral student Nada Hashmi outlines her project to bring mobile health clinics to rural areas in Saudi Arabia.

"He sets a great example of how to best use resources for the better," Hashmi said. "He forced me to think of the big picture and challenged me to tackle health issues at a global level--which was great."

MIT business graduate student Ariel Santos presents Gates with his project, which looked at how to use business analysis to evaluate the effectiveness of health care projects.
