Dr. Worthylake obtained his Bachelor of Science in Physics from Southern Oregon State University in 1986. His Masters in Physics was awarded by the University of Oregon in 1991 and his Ph.D. in Biochemistry was awarded in 1998 by the University of Utah. From 1998 to 2004, Dr. Worthylake has been working with Dr. John Sondek at the University of North Carolina studying the mechanism of activation of Rho GTPases by members of the Dbl family of guanine nucleotide exchange factors.
