I have been teaching at Cal State LA since January 2009. It's been a pleasure to meet many enthusiastic learners here, and work with very supportive faculty-colleagues and staff.
My specialization is in biomedical engineering, and I love helping students to explore and get involved with the BME field. There is unlimited opportunity to improve healthcare and quality of life for people with such a wide range of health needs. To help prepare students for careers developing medical technology, we offer courses on Sensors, Instrumentation, and Data Acquisition; Biomedical Devices; Biomedical Signal Processing; and Neural Networks and Computation. Students majoring in EE can complete an Upper Division Specialization in Biomedical Engineering. Together with other colleagues in the ECST College, we also have developed an Introduction to Biomedical Engineering course and a Biomedical Engineering Minor Degree program. I also enjoy teaching a variety of courses ranging from electronics to signal processing, and working with students on senior design projects as well as indepedent study projects and an engineering service learning program called BOOST.

Broadly speaking, my main research interests are in acquiring, interpreting, and modulating electrical signals in the body. For example, some of my research has dealt with a medical technology called deep brain stimulation, by which electrical current pulses are delivered to a deep structure in the brain called the subthalamic nucleus. This therapy is used in patients with movement disorders, such as Parkinson's disease. The question is why does it stop patients from experiencing symptoms like tremor, and how can we control it better?
My research laboratory is called Neural Engineering Technology Laboratory (NETlab). Years ago, our work focused on developing a new therapy centered around electrical stimulation of muscle nerves. This therapy is targeted to help spinal cord injury patients regain the abiilty to walk on their own. We conducted experiments in a rodent model of spinal cord injury in collaboration with Dr. Ray De Leon. We have a NeuroEngineering Journal Club.
My lab more recently has worked on developing mobile health technology to enable and encourage regular exercise for individuals with lower mobility impairment and who use wheelchairs. We developed an "exergaming" mobile fitness app which monitors physical activity levels, allows people in wheelchairs to carry out exercises in the form of entertaining games, and engages them in a virtual community of mobile fitness app users.
I am currently investigating neural signatures of spreading depression as a way of predicting stroke progression and ultimately developing an intervention to limit or prevent long-term damage. I am similarly seeking electrophysiological "biomarkers" of Parkinson's disease to develop closed-loop deep brain stimulation control algorithms.
