Research Focus

Lipids, commonly referred to as fat, are a large and diverse group of biomolecules that serve many roles within a cell. Lipids are the major structural component of cellular membranes, the primary means of cellular energy storage, mediators of cell-to-cell communications, and inflammatory factors. Since many lipids exist within the cell as large macromolecules, derived from a combination of smaller metabolic building blocks, it is critical to not only understand the abundance of lipids, but also their structural compositions.

At the CRI, I use my expertise in mass spectrometry and lipid biology to decode the biochemical information stored in lipid macromolecules. This information can be used to broaden our knowledge of lipid maintenance and metabolism in healthy animals and identify potential metabolic liabilities for the treatment of disease. I am specifically interested in how the lipid composition of a cell’s membrane sensitizes it to environmental stressors and prevents the growth and spread of cancer.

About Dr. Mathews

Thomas P. Mathews earned his bachelor’s degree in biochemistry from the University of Virginia and stayed to complete a Ph.D. in bioorganic chemistry. Following his thesis work, Dr. Mathews pursued postdoctoral fellowships at The Scripps Research Institute and Vanderbilt University Medical Center where he studied lipid metabolism and lipid signaling networks. In 2014, Dr. Mathews was awarded a fellowship through Oak Ridge National Laboratory to develop new tests for environmental and industrial toxins at the Centers for Disease Control and Prevention. Dr. Mathews joined the Morrison lab at Children’s Medical Center Research Institute (CRI) at UT Southwestern in 2017 as a senior research scientist focused on the development of mass spectrometry-based metabolomics methods.

In 2020, Dr. Mathews joined the CRI faculty as an assistant professor.
