Biosketch

I am a physician-physiologist fascinated by studying the human body and disease mechanisms. My undergraduate, graduate, and early postdoctoral research focused on peripheral sympathetic nervous system physiology. The sympathetic division of the autonomic nervous system is classically known for mediating the ‘fight or flight’ response. Still, it is also indispensable for body homeostasis during daily activities such as exercise, eating a meal, and regulating body temperature and immune responses. My research has included studying the mechanisms of voltage-gated calcium channel modulation mediated by G-protein coupled receptors. Voltage-gated calcium channels are critical mediators of depolarization-induced calcium influx into excitable cells, playing pivotal roles in various physiological responses. In recent years, my research has focused on skeletal muscle physiology and pathophysiology, focusing on myopathies induced by chronic diseases such as diabetes and heart failure. In recent collaborative multi-institutional projects, we are eager to unravel the role of calcium dysregulation in neurodegenerative conditions such as Huntington's disease and Alzheimer's disease with the hope of finding biomarkers, novel diagnostic tools, and new alternative therapies.

Research Interests

Neuronal and muscular physiology. Calcium signals and voltage-gated ion channels in excitable cells. 

Alterations of voltage-gated ion channels function and calcium signaling in neurons and muscle.

Pathophysiology of Diabetes, Denervation and Skeletal Muscle diseases.   

  1. One of the primary focuses of my research interest is the function of the sympathetic nervous system. During my PhD studies and early during my postdoctoral career, I studied mechanisms of ion channel regulation mediated by neurotransmitters, calcium signaling, and the role of extracellular S100A1. I demonstrated that different neurotransmitters and hormones can control the activity of ion channels via the modulation of the voltage sensing apparatus. Our group also discovered that specific patterns of electrical activity control the activation of NFATc1, a transcription factor that regulates myriad neuronal functions. I also identified a novel regulation mechanism of sympathetic neurons when S100A1 is added extracellularly. This form of regulation may occur during or after a heart attack and the accompanying ischemic damage or during neuronal damage.  My scientific findings from this initial stage of my research career have been cited numerous times in peer-reviewed journals and book chapters.
  2. Improving our understanding of skeletal muscle functions constitutes a prerequisite for better treating skeletal muscle diseases. Over the years, my colleagues and I have developed a range of research strategies to allow a vastly improved understanding of muscle physiology and disease conditions.
