Research in our laboratory involves medical instrumentation, biosignal
processing, modeling, simulation and development of novel algorithms to
understand dynamic processes and extract distinct features of physiological
systems. Two physiological systems currently being investigated are the
cardiovascular autonomic nervous system and renal autoregulatory mechanisms
as they relate to understanding hypertension. The objective of the cardiovascular
system is to detect, quantify, and interpret differences in dynamic characteristics
of the cardiac autonomic nervous system between normal and diseased subjects,
in an attempt to find a marker for increased risk of sudden cardiac death.
Identifying and quantifying differences in the dynamic characteristics
of autonomic function between normal and diseased conditions may lead
to a better understanding of the role of autonomic function imbalance
in diseased conditions, and should have important clinical and diagnostic
and prognostic application. The primary goal of the renal system is to
unravel the underlying reasons for the changes in autoregulatory mechanics
between normotensive and hypertensive conditions using various animal
models (e.g., normotensive, hypertensive rats and knockout mice).
The second category of research involves development of a portable biosensor
medical device and new robust detection algorithms to monitor and assess
cardiovascular conditions such as heart failure. The main goal is to design
and test the feasibility of a manufactured portable device that can be
used in conjunction with an Internet hospital.
Student Background: An ideal undergraduate should have a good engineering
and math background, especially an introductory familiarity with linear
systems, and linear algebra. Useful also are programming skills in C/C++
and MATLAB. Student should be also willing to be involved in experiments
involving either human or animals. Students majoring in Electrical Engineering,
Applied Math, Physics and Physiology with good math background, would
be ideal.
