Research Interests
Cardiovascular biochemistry, protein structure-function, enzyme mechanism, enzyme regulation, cardiac calcium transport regulation, congestive heart failure, drug discovery and natural products, cellular metabolism, warm water consumption as a wellness therapy to improve blood lipid status and reduce inflammation. Most recently using EPR spectroscopy to detect free radical generation and/or quenching by carbon nanotubes and carbon nanohorns. CAPABILITIES: Most basic wet lab biochemistry techniques, various structure-function-dynamics spectroscopic techniques (electron paramagnetic resonance, fluorescence), basic chemical techniques and analyses of biological samples.
