PROFESSIONAL EXPERIENCE
2000-present: Consultant and Chief Scientist,
ZeroTree, Inc., Calverton MD
Commercial Activity
Project: Assist in the design of software for a patent-pending wavelet-based transform encoder/decoder for image transmission over the wired internet.
Activity: Assist in integrating the encoder/decoder into a software-based video codec for transmitting video over the wired internet, in both batch and streaming modes.
Activity: Assist in imbedding into hardware the video codec to enhance its performance and increase its functionality.
Project: Assess the feasibility of applying redundant multi-resolution based transform methods to build a transform encoder/decoder for image transmission over the wireless internet.
Activity: Assist in negotiating an alliance between ZeroTree,Inc. and the Industrial Mathematics Institute (IMI), University of South Carolina, to pursue redundant, multi-resolution based filter designs that can address in an original way problems of communicating information over narrow band channels with significant and unpredictable data loss.
Activity: Assess the feasibility of applying a multi-resolution based transform encoder/decoder to problems of interactive, real time, distributed data management.

Project: Examine the use of algebraic indexes derived from the wavelet representation of multi-spectral image data to characterize the extent of spatial correlation (with NASA Goddard, Code 923);
Activity: Investigate the use of support vector machines to develop robust, supervised classifiers for extracting information form hyperspectral data;
Activity: Investigate the use of wavelet and other windowed and multi-resolution transforms to discriminate information from spatially dependent multi- and hyperspectral imagery, and use the results to contribute to the design of protocols to fuse multi-spectral and other sensors to acquire the relevant information;
Activity: Investigate the use of wavelet and other windowed transforms to extract signal from noise in hyperspectral data from vegetation and soils;
Project: Develop an application to register multi-spectral imagery using nonlinear wavelet compression and singular value decomposition (with KT-Tech Inc., and NASA Goddard, Code 935);
Other Activity
Wrote or contributed to technical and management sections of numerous
