At the Sociomicrobiology & Microbial Interactions Laboratory (SMIL) of the school of STEM, Dr. Paul focuses his research on bacterial communication. Communication is the sole means by which effective networking and co-existence is accomplished amongst living beings. Bacteria have their own chit-chats that carefully coordinate their effective strategies via certain signal molecules that includes N-acyl homoserine lactones (AHL). This Quorum Sensing (QS) regulated biofilm formation and virulence factor secretion are of concern as they are involved in surface-attachment, toxicity, and pathogenicity. Targeting QS is a promising strategy to inhibit undesirable bacterial traits and is referred to as Quorum Quenching (QQ). A clear understanding of the inhibitors of microbial communication systems is vital to dismantle their networking and co-working. The (SMIL) employ various phytomolecules as quorum sensing inhibitors (QSIs) to cut off communication between these bacteria, so as to hinder their combinatorial attacks. Metabolites of various soil microorganisms are also sought as effective QSI candidates. Researchers at the SMIL use naturally occurring QSI molecules towards biofouling-control of membranes. Natural compounds are also explored as QSI agents to control plant diseases.
Dr. Paul has published several research papers in the area including book chapters.

Dr. Paul served as an Associate Professor for eleven years at Konkuk University in Seoul, South Korea before taking up the position of Associate Professor of Biology with the Truett McConnel University, in the fall of 2018. Dr. Paul’s Ph.D. dissertation elucidated the mechanisms involved in beneficial attributes of rhizobacteria in crop plants. His postdoctoral work include research in fields of Plant Growth Promoting Rhizobacteria, Microbial Ecology and Microbial salt stress tolerance. His interests also include measures of disruption of bacterial communication systems, the so-called Quorum Sensing in bacteria, using Quorum Quenching Phytomolecules. Dr. Paul believes that these beneficial microorganisms in the natural environment and Phytomolecules from medicinal plants are liberally packed and deposited by our Creator God into the nature to protect and heal. God has created everything beautiful and perfect. Dr. Paul thinks it’s exciting as a Scientist, to explore what God has prepared for us in this beautiful earth, to heal and for harmony.
Paul has been active in campus Christian ministries in preaching the Word of God and he has a passion for serving the Lord especially among the youth. He has ministered in Korean, Chinese, Mongolian, African and other multicultural churches. He understands that true hope is found in Christ alone and the truth will set people free. He believes, It’s the mission of every Christian professor to equip students with faith in Jesus Christ and to raise up a generation, empowered by the Holy Spirit, who will carry the power and presence of God in their lives.
