Brief Research Summary

• High performance computing via nonlinear optics: The dominant paradigm of solid-state digital computers is bound to reach the technological limits with no viable alternative in sight. Thus, it is time to seek novel physical realizations of computing. We evaluate the possibility of utilizing nonlinear optical effects as a computational platform. This may pave the way for the development of new physical realization of computation.
• Quantum reservoir engineering: Realistic models of large quantum systems must include dissipative interactions with an environment, which may be of various natures (e.g., spontaneous emission, fluorescence, collisions, etc). It is widely believed that the dissipative forces destroy quantum features. This opinion is being challenged by reservoir engineering. In particular, it is possible to preserve and even enhance the quantum dynamical features of a system by judiciously coupling the system to a dissipative environment. Moreover, dissipative dynamics opens unique possibilities, not offered by potential forces, such as the violation of Newton’s third law.
• Novel optical technology exploring quantum-classical analogies: Optical analogs of quantum phenomena rely upon the resemblance of the Schrodinger equation to the wave equation with the paraxial approximation, where the wavefunction is replaced by the electric field. Using this analogy, we are developing new optical technologies for sensing and communication by adapting quantum reservoir engineering to the realm of classical optics.
• Quantum-classical hybrids: The interplay between quantum and classical systems is one of the most fascinating open questions of modern science. In particular, classical-quantum hybrid systems, in which both quantum and classical degrees of freedom interact, lies at the heart of several scientific disciplines ranging from chemistry to quantum gravity. Despite its importance, a fully consistent classical-quantum theory has eluded the countless attempts to develop one. In order to describe the hybrid systems, we are utilizing the Koopman-von Neumann (KvN) theory, which provides a quantum-like description of classical mechanics in terms of wave functions and self-adjoint operators. The KvN approach is based on a fundamental observation:  both classical and quantum evolutions are represented by unitary transformations. Although widely used in dynamical system theory, the KvN method remains unknown in other areas. The KvN approach is diametrically opposite to the phase-space representation of dynamics, which has been the basis of all the previous attempts to construct hybrid systems, providing a classical-like description of quantum dynamics in terms of momenta and coordinates.
• Theory of theories: We are living in the age of omnipresent data. A much-needed capability is to convert the collected data, irrespective of its nature, into knowledge characterizing the phenomenon that generated the data. This is a bottom-up approach, when a dynamical model is inferred from observed data. Whereas, the top-to-bottom approach refers to when a model is proposed first and then its predictions are confronted with observations (e.g., the least action principle). We are developing the bottom-up framework of Operational Dynamical Modeling that will allow physical models to be distilled directly from measured data in a systematic way. This approach will not only enable to obtain efficient models for complex systems, but also solve open problems in nonequilibrium quantum dynamics.
• Superoscilations: If over a brief time interval, we combine several light waves of different wavelengths into an almost perfect destructive interference, the combined electric field does not become exactly zero. Instead, the field performs weak and rapid oscillations, the superoscillation, that is faster (with a seemingly shorter wavelength) than the original light waves that are combined. We experimentally and theoretical develop the applications of this phenomena to enhance optical sensing.

While I have worked throughout the United States, my career has focused on the rivers and wetlands in the lower Mississippi River valley. These efforts have been as varied as studies to understand sediment deposition and nitrogen dynamics in bottomland hardwood wetlands in Mississippi River tributaries, to sampling the water chemistry, ecology and groundwater to over forty rivers in the Mississippi Embayment, helping to develop Level IV ecoregions for the lower Mississippi Valley, and coordinating studies to assess the efficacy of river diversions.

In the most recent couple of decades, I have been involved in creating, developing and directing large interdisciplinary research programs associated with the Mississippi River and its delta, including serving as the Chief of the US Geological Survey’s National Water Quality Assessment Program’s Mississippi Embayment project, and the Director of both the Louisiana Coastal Area Science and Technology program and the US Army Corps of Engineer’s Mississippi River Geomorphology and Potamology program.

My current interests include developing an improved understanding of the values of the residual Mississippi River floodplains, further understanding sediment dynamics in the river and how they should be measured and developing programs by which principles of river science and engineering can be more readily conveyed to river management professionals across the country.

I began my professional career with the U.S. Fish and Wildlife, National Reservoir Research Program as a biological technician. A few years later, I began working for the U. S. Army Corps of Engineers (USACE), Engineer Research and Development Center (formerly Waterways Experiment Station) in Vicksburg, MS where I continue today as a technical team leader in the Environmental Laboratory. Working for USACE in the 1980’s and 90’s allowed me to witness major changes in the environmental ethics of this organization. Our research supported these changes by quantifying environmental impacts of federal water resource projects (e.g., flood control, commercial navigation) on aquatic resources as required by the National Environmental Policy Act. We essentially completed sections of Environmental Impact Statements for USACE Districts. Also in the 1990’s, we began developing field protocols and statistical models to determine the benefits of ecosystem restoration as part of the Water Resource Development Acts. Our research resulted in both mitigation and restoration techniques to either offset negative impacts or provide ecosystem benefits.

In the early 2000’s, the Team began studying Pallid Sturgeon, a federally endangered species living in the Mississippi River. We were now assisting USACE Districts and Divisions in compliance with the Federal Endangered Species Act. We branched out to include research projects on seven other species of sturgeon that live in our navigable rivers across the United States. About this time, Asian Carp were rapidly colonizing the Mississippi River and tributaries. We assisted USACE and other federal and state agencies in monitoring population expansion, evaluating impacts to native species, and conducting laboratory studies on deterrents to expansion including electrical and hydraulic barriers.

We now have an interdisciplinary research team in the fields of ichthyology, fisheries biology, aquatic entomology, malacology, and watershed assessment. I continue to collect field data and develop products on fishery resources of the Mississippi River and tributaries. As an adjunct professor at Tulane University, I will continue to share these experiences in an applied approach to our river science and engineering courses.
