Bill Gates made the first stop on his college tour on Monday, speaking at the University of California Berkeley, before touring one of its biology departments.
Gates heads to the lab
Bill Gates talks with UC Berkeley professor Dan Portnoy as he tours Portnoy's biology lab. Portnoy's research looks at the listeria bacteria and how the immune system interacts with it, a subject that has implications for vaccine creation.
The tour followed the morning speech that kicked off his three-day college speaking tour.
