Research Interests

Our research is focused on understanding the biochemical, structural, and cellular mechanisms by which sensory receptors (e.g., transient receptor potential and potassium ion channels) contribute to somatosensation. These sensory receptors are polymodal membrane proteins that respond to a broad range of physical (e.g., heat, cold, and pressure) and chemical (e.g., acid, irritants, and inflammatory mediators) stimuli to depolarize sensory neurons and elicit or intensify inflammatory pain. Specifically, we are interested in determine how different stimuli induce channel activation and identifying regions that specify stimuli detection. Our laboratory follows two main avenues: (1) in vitro biochemical and biophysical approaches to study ion channel regulation in response to different physical and chemical stimuli. (2) in vivo approaches to characterize sensory receptors with novel physiological roles. Our research involves a multidisciplinary approach that includes biochemical procedures, electrophysiological and structural methods together with molecular genetics and behavior experiments.
