Introduction
Computer Scientist. I received a Ph.D. and an MSc. degrees in Computer Science at the University of Colorado at Colorado Springs (UCCS). I work as a Senior Computer Scientist at Symetrix Corporation on R&D focused on cryptography and data science. I investigate new ways of protecting, representing, processing, transmitting, and storing data.

In this work, we aim to address the challenge of expanding Blockchain Technologies (BT) by implementing a somewhat homomorphic encryption scheme that not only enables computation on encrypted data but also yields a key update protocol with which one can selectively reveal consolidated data from a blockchain application. Our constructions are meant...
We propose general-purpose methods for data representation and data concealment via multivector decompositions and a small subset of functions in the three dimensional Clifford geometric algebra. We demonstrate mechanisms that can be explored for purposes from plain data manipulation to homomorphic data processing with multivectors. The wide variet...
Data encoding is widely used for a variety of reasons. Encoding schemes in general serve to convert one form of data to another in order to enhance the efficiency of data storage, transmission, computation and privacy, to name just a few. When it comes to privacy, data may be encoded to hide its meaning from direct access or encrypted to attain a c...
