Research Interests 

My research focuses on investigating the impact of xenobiotics and pharmacological agents on ion channels and proteins involved in regulating cellular calcium homeostasis. The studies conducted will focus on two key calcium ion channels (a) plasma membrane calcium entry channels, the store operated calcium entry channels (SOCE) and (b) ligand-gated calcium release channel, the Ryanodine receptor. These calcium ion channels play a pivotal role in regulating critical cellular functions such as gene transcription, neurotransmitter release, immune cell regulation, cardiac and skeletal muscle contraction. Xenobiotics such as brominated flame retardants and polychlorinated biphenyls (PCBs) have been known to cause various endocrine, neurological and immunological deficits in humans. Although the mechanisms of toxicity are yet unknown, these agents are thought to dysregulate calcium homeostasis and calcium-dependent signaling pathways. The purpose of studies in my laboratory will be to identify and elucidate the underlying mechanisms of toxicity elicited by this class of xenobiotics and other environmental contaminants.
