Research Areas

Research Interests
I study antibiotic resistance in pathogenic bacteria. My current research focuses on: 1) mechanisms contributing to antibiotic resistance, with particular focus on the interactions of resistance plasmids with CRISPR-Cas systems, and 2) using in vivo-relevant growth substrates to characterize the physiology of pathogenic bacteria. The long-term goal of my research is novel antimicrobial development.

Microbiologist Aims to Thwart Antibiotic Resistance
Dr. Kelli Palmer is running her own laboratory as an assistant professor of molecular and cell biology at The University of Texas at Dallas. Her work focuses on a better understanding of how bacteria develop resistance to antibiotics. One approach she is taking involves sequencing entire genomes of different bacterial species to identify and characterize genetic mutations that lead to antibiotic resistance. She also is investigating the role genetic material called plasmids and transposons play in conferring resistance. These tiny bits of DNA often encode antibiotic resistance genes, and they can be transferred from bacteria that are drug-resistant to bacteria that are not. Understanding this process might lead to more effective ways to curtail the spread of antibiotic resistance, Palmer said.
Biologist Investigates How Gene-Swapping Bacteria Evade Antibiotics
A scientific peek into bacteria boudoirs is revealing how “sex” among disease-causing microbes can lead different species or strains to become resistant to antibiotic medications.

Dr. Kelli Palmer, assistant professor of biological sciences at The University of Texas at Dallas, is conducting research aimed at understanding the underlying mechanisms by which bacteria acquire antibiotic resistance genes from one another.
