Kathlynn Brown, Ph.D.

Assistant Professor

Department: Internal Medicine, Simmons Comprehensive Cancer Center

Graduate Programs: Cancer Biology, Cell Regulation


Kathlynn Brown is an Assistant Professor of Internal Medicine and a member of the Simmons Cancer Center at the University of Texas Southwestern Medical Center. Dr. Brown obtained her PhD in organic chemistry at the University of Texas at Austin during which time she received fellowships from the Mahler Memorial Foundation and the Organic Division of the American Chemical Society. She continued her training at the University of California at San Francisco, where she was a Damon Runyon Walter Winchell Postdoctoral Fellow. She moved to UT Southwestern in 1998 to join the Center for Biomedical Inventions. In 2005 she became tenure-track faculty in the Department of Internal Medicine and the Harold C Simmons Comprehensive Cancer Center.

 In her independent career, she has utilized her multidisciplinary expertise in organic chemistry, peptide chemistry, biochemistry, and molecular biology to address challenges in biomedical research.  Her laboratory was among the first laboratory was among the first to adopt cell-based biopanning of phage-displayed peptide libraries. Using this approach, she has developed a suite of high affinity peptides that target a variety of different cell types. Her research team is currently focusing on the development of peptides that target non-small cell lung cancer for use as delivery vehicles for drugs, nanoparticles, and toxins. Additionally, the peptides are being utilized as molecular imaging agents for diagnosis and classification of lung tumors.
