Research Interests

Our research aims to investigate the intricate crosstalk between the gut and heart in alcohol misuse-related pathologies. By employing a multidisciplinary approach, including echocardiography, cardiac pressure-volume catheterization, laser speckle contrast imaging, cell culture models, RNAscope, histology, or other in vitro techniques, we strive to unravel the complex interplay among gut bacteria-derived substances, cardiovascular endocannabinoids, and dysfunction associated with alcohol misuse. Understanding this relationship is crucial, as endocannabinoid signaling has significant impacts on cardiac performance, vascular tone, and inflammation. Our findings will contribute to a deeper understanding of the pathophysiology involved, potentially identifying novel therapeutic targets for mitigating cardiovascular dysfunction associated with the gut-heart axis in individuals with alcohol use disorder.

Teaching Activities

  • Journal club co-organizer for undergraduate and post-baccalaureate interns (title: “Cannabis: Curse or Cure” focusing on the basics of (endo)cannabinoid signaling, crystal structure of cannabinoid receptors and their pharmacology, the effects of plant-derived cannabinoids).
  • Mentoring NIH post-baccalaureates and summer interns.
