Dr. Mathis’s career path is unique as she started out as a physics major and she is now an integrative physiologist. Research has always been an underlying force in her career and she was able to carve out her niche after research training with her mentors, Dr. Patricia Molina (graduate school) and Dr. Michael Ryan (postdoc). She is thrilled to now lead a team of scientists interested in hypertension and lupus research. Beyond science, Dr. Mathis is devoted to K-12 outreach and diversifying academia and she thoroughly enjoys being ‘Mommy’ to her four daughters.
Overall, the Mathis Laboratory investigates mechanisms involved in the pathogenesis of hypertension and renal injury. The lab is highly focused on chronic renal inflammation and how it contributes to the development and maintenance of hypertension and renal injury. We hypothesize that neuroimmune mechanisms that normally subside aberrant inflammation are impaired in hypertension. To investigate our hypothesis, we use a strain of lupus mice that spontaneously develops chronic renal inflammation and has a high prevalence of hypertension. We manipulate these mice to reduce inflammation and to slow the progression of hypertension and in the process, we have determined and continue to investigate potential alternative therapeutic strategies for lupus.

- Cholinergic anti-inflammatory pathway and hypertension—investigating how failure of endogenous neuroimmune mechanisms meant to control inflammation can lead to chronic renal inflammation and hypertension.
- Positive allosteric modulators and chronic renal inflammation—investigating if accentuating acetylcholine signaling peripherally and centrally reduces inflammation and improves behavior in mice with lupus. These studies are in collaboration with Dr. Victor Uteshev of UNTHSC Pharmacology and Neuroscience.
- Sex differences in lupus—determining sex differences in the development of lupus-induced hypertension and renal injury.
- Early life stressors—examining the impact of early life stressors on the pathogenesis of lupus and autoimmunity.
