John H Richburg
The focus of Dr. Richburg's research is on characterizing the molecular and cellular mechanisms that initiate testicular germ cells to undergo apoptosis (programmed cell death) after injury by environmental or chemotherapeutic agents. He is the recipient of a $1.5 million National Institutes of Health award to study the adverse effects of environmental toxicants on male fertility and disease. Richburg says that exposure to low levels of phthalates (used in the manufacturing of plastics) during the fetal period of testicular development may cause testicular cancer or infertility later in adult life. His lab is internationally recognized for its work on revealing the molecular mechanisms that regulate cell death in the testis and the influence that environmental chemicals have on these processes.
