- R. Johnson Lab – Focuses on mechanisms of breast cancer dissemination to bone, tumor recurrence in distant metastatic sites, and protecting skeletal health in the setting of tumor-targeted agents to prevent bone metastases and fractures.
- Kirabo Lab– The overarching goal of the Kirabo Lab is to define mechanisms that lead to health disparities in cardiovascular disease. Dr. Kirabo's lab is working to define mechanisms that contribute to inflammation and autoimmunity in cardiovascular disease, with a particular focus on immune mechanisms of excess dietary salt-induced cardiovascular and kidney disease, and how this is modulated by the gut microbiota and viral infections including HIV/AIDS.
- B. Knollmann Lab – Investigates molecular arrhythmia mechanisms involving alterations in the functioning of ion channels, myofilaments and calcium release channels. His lab is developing and testing new anti-arrhythmic therapies in human induced pluripotent stem cell models, in animal models and in humans.
- B. Kroncke Lab – Aims to accurately predict the meaning of genetic variants to the individuals who carry them. Dr. Kroncke's approach is to collect as much phenotype information, at high and low resolution, as is feasible for the largest number of variants and then leverage high-throughput experimental and computational methods to fill in the details for yet uncharacterized variants.
- J. Luther Lab – Focuses on the role of the renin-angiotensin-aldosterone system on glucose regulation using human and animal models. Dr. Luther’s group uses pharmacologic tools and genetic interruption to investigate the effects on insulin secretion and insulin sensitivity in vivo. Dr. Luther is also the director of the Vanderbilt AHA Comprehensive Hypertension Center, where he evaluates and treats resistant and secondary causes of hypertension such as primary aldosteronism and renovascular hypertension.
- G. Milne Lab – Studies the metabolism of oxidized lipid mediators in health and human disease. The lab has a particular interest in the use of oxidized lipid mediator metabolites as biomarkers of their endogenous production. Dr. Milne is the Director of the Eicosanoid Core and the Neurochemistry Core, which each provide analysis and quantitation of these small molecules using mass spectrometry.
- J. Mosley Lab – Focuses on identifying translational applications of polygenic variation to clinical medicine to improve health care delivery, reduce unnecessary health care utilization and improve risk stratification. This work typically leverages data from electronic health record (EHR) data sources and epidemiological studies.
- K. Murray Lab – Investigates the molecular determinants of the substrate for atrial fibrillation, the most common sustained cardiac arrhythmia. Current efforts are focused on targeting reactive lipid dicarbonyls generated by oxidative stress that mediate a major component of injury in this setting.
- D. Patrick Lab – Studies mechanisms of inflammation in autoimmune and cardiovascular diseases. Dr. Patrick has defined a unique pathway for immune activation by isolevuglandins in systemic lupus and how these contribute to hypertension in this disease. He is also investigating mechanisms of how isolevuglandins cause formation of neutrophil extracellular traps and the role of this in hypertension.
- S. Peck Lab – Focuses on understanding the role that extracellular matrix (ECM) components play in the development and homeostasis of musculoskeletal tissues, as well as identifying mechanisms behind pathologic dysregulation of the ECM that lead to disease and degeneration. Dr. Peck's lab combines analytical chemistry, biochemistry, and molecular biology methods to identify the chemical composition of the ECM and how particular components regulate biological function of musculoskeletal cells, ultimately aiming to apply our findings to developing new regenerative therapeutic strategies for tissues such as bone, intervertebral disc and cartilage.
- E. Rendina-Ruedy Lab – Focused on developing a comprehensive understanding of how metabolic pathways impact bone health. As such, the Rendina-Ruedy lab has ongoing projects aimed at understanding how bone cells, and cells within the bone marrow niche, store, mobilize, and utilize various metabolic substrates.

Spotlight on the Kirabo Lab
Annet Kirabo, DVM, MSc, PhD, and her team studied the effects of salt intake on blood pressure, and found that patients who eat in excess of the American Heart Association's recommendation of one teaspoon of salt per day have altered gut microbiota, which leads to high blood pressure and inflammation.
