In a Bronx, N.Y., high school where the dropout rate was 60 percent, a guidance counselor declined to give Stephon Alexander an application to an Ivy League university.

"You won't get in," Alexander recalls the counselor saying. But Alexander proved the counselor wrong.

After a BS at Haverford and a Ph.D. in Physics from Brown University, the counselor appears to have gotten it wrong. After his Ph.D., Alexander was at London's Imperial College.

Currently he is a member of the SLAC high energy physics group and Stanford's ITP (Institute for Theoretical Physics).
