About Me

I have completed the requirements for a Ph.D. in Electrical Engineering at the University of Florida.
 
My Research Interests

During my stay in Florida, I worked in the fields of Information Theoretic Learning, Blind Source Separation and Subspace Projections. I am particularly interested in how results from these fields of study may be applied to multi-speaker convolutive speech separation to improve hearing aids, time-varying EKG demixing to separate the fetal heartbeat from that of the mother, and neuronal feature extraction for prosthesis control. Other interests include communication theory (especially magnetic storage) and adaptive filter theory (especially general purpose criteria for supervised and unsupervised machine learning).
 
Research Goals

Better understand the properties of the MRMI-SIG algorithm, and determine applications for which it is particularly suited. These applications include, but are not limited to: improving hearing aids, reducing co-channel interference in communications channels, fetal EKG separation, feature extraction/subspace projection for recognition/classification pre-processing, and blind deconvolution/equalization.
