Butch Moncla, PhD

Research Associate Professor, Department of Obstetrics, Gynecology & Reproductive Sciences, University of Pittsburgh



The laboratory specializes in solving difficult problems and the development of new thought and protocols requiring expertise in microbiology and biochemistry. Current studies center on the interactions of microbial flora and the glycoproteins, primarily mucins, found in the vagina to determine if these protective barriers are altered when intravaginal products are used. Because certain vaginal bacteria maintain the health of the vagina, the lab tests drugs to ensure that these drugs do not interfere with the bacteria. The lab also tests HIV-prevention drugs to ensure they are not broken down in the vagina. Additionally, Dr Moncla is still active in studies of sexually transmitted pathogens and bacterial glycobiology.

Dr Moncla’s expertise is in anaerobic microbiology and rapid methods of detection and identification. He has extensive experience in infection control and disinfection, providing considerable expertise in the killing and control of microbial pathogens. Dr Moncla holds patents for the sterilization of lipids. The Sonicare Ultrasonic Toothbrush was developed in his laboratory. As the Founding Scientist in the MicroProbe Corporation, he made significant contributions to the development of the DNA-based “Affirm” rapid diagnostic instrument for in-office use.
