| Dr. Xue is a Professor of Molecular, Cellular,
and Developmental Biology at the University of Colorado at
Boulder. He received his Ph.D. in 1993 from Columbia University
and was a postdoctoral fellow at MIT from 1994-1997 before
he joined the faculty at the University of Colorado at Boulder
in the Fall of 1997. Dr. Xue has received numerous awards
including Helen Hay Whitney Foundation postdoctoral fellowship,
the Searle Scholar Award, the Burroughs Wellcome Fund Career
Award, and the Sandler Program for Asthma Research Early Excellence
Award.
Dr. Xue's main research interests lie in studying the mechanisms
of programmed cell death (or apoptosis) and various human
diseases such as neurodegenerative diseases, cancer, and autoimmune
disorders that are caused by abnormal apopotosis. He has been
using genetic, molecular, biochemical, and structural biological
approaches to study the mechanisms that control, activate
and execute programmed cell death in the nematode C. elegans
and in mammals, with a focus on studying the regulation and
activation of neuronal cell deaths. His laboratory recently
identified more than 15 genes that act downstream of the C.
elegans cell death protease CED-3 to execute programmed cell
death and at least eight new genes that control sexually dimorphic
apoptosis, which is an ancient developmental process crucial
for the reproduction of animal species.
