Our goal is to understand how interactions between different microbes and the female urogenital tract influence the link between the vaginal microbiome and health problems affecting women and their babies.
The vagina is colonized by commensal bacteria that help protect it from infection. However, 30% of women harbor a polymicrobial vaginal microbiome (bacterial vaginosis, BV) that is seemingly less protective. BV is associated with sexually transmitted infections (HIV, HPV, HSV, gonorrhea), urinary tract infections (UTI), pelvic inflammatory disease, infertility, intrauterine growth restriction, preterm birth and stillbirth.
Our lab aims to understand how host-microbe and microbe-microbe interactions in the female reproductive and urinary tracts are responsible for BV-associated health problems. We develop and employ a variety of small animal and cell culture infection models and analysis of human clinical specimens in our current projects investigating BV, UTI, HPV-associated cancers and adverse pregnancy outcomes. We hope our studies will translate into new vaginally focused prevention and treatment strategies that will improve the lives of women.
Mentoring
I am eager to support trainees and help them discover and reach their research and professional goals. I have completed the DBBS Mentorship Training program and was a 2023 COMPASS Training and Mentorship Scholar. Please contact me to learn more about currently available projects or if you have your own research questions in the area of urogenital microbiology that you would like to pursue with us.
Nicole M. Gilbert, PhD
Principal investigator
Nicole Gilbert came to St. Louis after graduating from Concordia University, NE in 2005 to study fungal cell wall biology and pathogenesis in the lab of Jenny Lodge at Saint Louis University School of Medicine. One PhD (and two kids) later, she moved down the road to Wash U, and switched to women’s infectious disease research. Following her postdoc (and one more kid) in the lab of Amanda Lewis developing mouse models to study bacterial vaginosis, she completed a K01 Career Development Award examining the effects of Gardnerella on the urinary tract under the mentorship of Amanda Lewis and David Hunstad.
She joined the Department of Pediatrics in 2020 and started her lab in 2024. Her research uses in vivo and in vitros model systems in parallel with analyses of clinical specimens to specify the mechanisms underlying known associations between certain vaginal microbiome states and infectious disease such as UTI and HPV-associated cancer, and adverse pregnancy outcomes.
She enjoys playing games, watching movies (preferably from the ‘90s and 00’s), hiking with her husband, Joel and her kids. She also likes reading and going to concerts.
