Research Interests

The overall objective of my research work is to understand what is happening in host cells during chlamydia infection of the female genital tract that leads to the process of chlamydial pathogenesis which ends in tubal pathologies and infertility. My work involves the use genomics, proteomics, metabolomics and systems biology in answering research questions that arise from my studies. My research focus involves elucidating the molecular mechanisms underpinning the pathogenesis of chlamydial infection. Results generated from my lab have identified some novel and differentially expressed miRNAs that can be viable biomarkers for pathologies associated with Chlamydia infection. In addition, we are studying genes involved in antibacterial response, apoptosis, inflammation and epithelial to mesenchymal transition that are altered during chlamydia infection leading to tubal factor infertility, which will potentially fill this gap in knowledge. Results from my lab has also opened up new areas of research which includes elucidating the effects of circadian rhythms on chlamydia infection and pathogenesis. My research is innovative and utilizes recently described key regulatory molecules, state-of-the-art molecular techniques and novel technologies in a focused set of studies to achieve the groundbreaking feat of discovering possible therapeutics/biomarkers for pathologies caused by Chlamydia infection. I have submitted datasets to the NCBI Geo webpage (https://www.ncbi.nlm.nih.gov/geo/subs/?view=series&display=100), which is the most comprehensive RNA-Seq dataset from mice experiments. I am currently mentoring graduate students in my lab. I have had medical students and minority undergraduates from Spelman College (RISE fellow) and Georgia Gwinnett College in my lab.
