A. Personal Statement

My primary research interest is theoretical physics with specialization in the foundations of relativistic quantum theory using Lie algebras and groups where my initial work developed a new formulation of relativistic position operators and a relativistically covariant formulation of the Foldy-Wouthousen transformation for charged spin ½ particles. Later I found a new method of decomposing the Lie group and algebra for the most general linear n-dimensional transformations into a n-dimensional scaling algebra and an n(n-1)-dimensional Markov type Lie Algebra. This latter algebra, when restricted using a particular Lie basis, generates all possible continuous Markov transformations (a Markov Monoid (MM)). This MM is instrumental in the study of entropy, information theory, and diffusion. One of my most important discoveries is that the MM Lie algebra is exactly isomorphic to all possible networks. This now allows the power of Lie groups and algebras to link to the theory of Markov transformations, and likewise to the full theory of networks and their classifications including a powerful algorithm for network cluster analysis based upon a model of flows of a conserved entity in a network.  I recently developed a methodology for transforming numerical data tables (of entities vs. properties) into a pair of networks (one for entities and one for properties). This allows the full power of my clustering algorithm (now developed in Python) to be applied to cluster identification with medical data, engineering, and other scientific data structures for automated cluster analytics. My $2.5 DARPA funding in 2004-2008 allowed me to make the breakthroughs that use Markov Entropy metrics and clustering for analyzing networks. I just completed the design and development and Python programming of a standardization of for numerical data that integrates a numerical value with its units of measurement, uncertainty, and unlimited metadata tags. This standard is optimal in speed and minimal in code size and also allows parallel processing. I developed this MetaNumber Python Code and was PI of an interdisciplinary team comprised of 18 faculty and 22 graduate students studying its applications in multiple domains.  I continue my research of integrating information theory, Markov Chain Theory, Lie Algebras, Measurement Theory, MetaNumber (MN) structures, and related concepts.  Recently, I developed a method for expressing standard Riemannian Geometry as a generalized Lie Algebra based upon the Heisenberg Lie algebra; then I applied this framework to expressing Einstein’s general theory of relativity and Riemannian Geometry in general in terms of this algebraic structure allowing it to be integrated with the Heisenberg and Poincare Lie Algebras of Quantum Theory as well as Yang Mills’ gauge SU(3) x SU(2) x U(1) Lie Algebras of the Standard Model. I devote my time now to a study of this resulting complex system. My university’s R&D team (the Advanced Solutions Group) developed multiple advanced software systems and I was the sole PI for over 120 grants while at USC totaling $14M between 1992 and 2016 making me one of the highest funded faculty at the university.
