Research Interests

Since 1997 Dr. Reddy has been developing Doppler and physiological signal acquisition and processing systems in collaboration with Indus Instruments. Using the custom-built sensors and devices in the Instrumentation Development laboratory has developed measurement techniques and applications that were used in large animals and humans to study cardiovascular function in mice. Some of these include non-invasive measurement of systolic and diastolic pressure in mice with tail-cuff and pulsed Doppler, determination of aortic input impedance in mice to evaluate the systemic load on the left ventricle of a mouse, and noninvasive measurement of coronary flow velocity in mice. We currently use noninvasive Doppler methods to measure cardiac velocities, blood flow velocities in central and peripheral vessels, arterial pulse-wave velocity, tail-cuff blood pressure, arterial wall motion, and tissue Doppler without image guidance. We also use imaging methods to measure cardiac and vascular dimensions. Invasive methods are used mainly to measure aortic, arterial, and left ventricular pressure. Efforts are underway to develop non-invasive indices of aortic impedance using aortic wall motion and velocity measurements.

Dr. Reddy's current research interests include evaluation of cardiac and vascular mechanics in senescent, disease, transgenic, surgical models of mice. Some of the mouse models we studied include atherosclerosis, dwarf, myocardial infarction/remodeling, pressure overload, hypertension, and absent vascular tone. Using noninvasive methods we phenotype the animals as abnormalities develop and progress, and monitor the cardiovascular system as it adapts and compensates for deterioration of function or for missing or over-expressed proteins. Our main goal is to translate what learn in mice to humans for early detection and screening of vascular diseases at an early stage when potential therapies can be most effective at preventing disease progression.
