Engineer, physicist, acoustician, executive, and business owner with broad interdisciplinary expertise in model-based and statistical signal-processing, machine-learning/AI (ranging from rule-based to modern deep learning), and computational, experimental, and theoretical modeling. As an adaptable generalist, able to rapidly assimilate new information, I work across fields to understand, model, and simulate phenomena in the natural world and in engineered systems. Interacting regularly with academe, government, and industry, I rigorously apply domain knowledge and scientific insight to address real-world problems while balancing concerns of accuracy and computational efficiency.Specialties: ▪physics-based modeling for real-time simulation and training (e.g., auralization for VR, sim/stim sonar training)▪mathematical and computational modeling of sound fields for propagation (in the ocean, in auditoria and rooms) and scattering (from objects and rough surfaces)▪combining numerical modeling of physical phenomena with machine-learning models (e.q., wave physics models or oceanographic models with generative deep networks) for interpolation and extrapolation, data augmentation, and sensing▪signal processing for detection, classification, localization, and segmentation using both traditional methods as well as modern L1 /compressive-sensing approaches and novel applications of deep neural networks▪psychoacoustics, human-mimetic signal processing, and cognitive modeling▪acoustics of concert halls and systems of coupled roomshttps://contact.experty.io/jasonesummers

Owner / Chief Scientist / Managing MemberAria Jan 2010 - PresentMadison, Va And Alexandria, Va And Seattle, WaARiA applies broad interdisciplinary experience in physics, modeling & simulation, signal processing, machine learning, and cognitive science toward innovative basic and applied research (DoD 6.1/6.2/6.3) that tackles real-world problems faced by end-user customers in government and industry, with a focus on the military and intelligence communities. We specialize in developing algorithms and methods that enable (1) real-time physics-based modeling for simulation and training and (2) physics-based and biology/cognition-inspired approaches to signal processing and machine learning that enable automated systems to perform pattern recognition in complex and changing environments.In addition to management of business operations and ARiA IR&D, I serve as PI and PM for multiple R&D projects for DoD agencies (including NAVSEA, ONR, and U.S. Air Force), government agencies (including DoJ) and private clients (firms and individuals). This work includes research in physics-based signal processing, development of simulation-based training tools, developing new methods for feature/representation learning, development of cognitive systems for legal-document analysis and natural-language question-and-answer capabilities, and developing an interactive video game addressing STEM education in physics and acoustics for secondary students. -

Acoustic PhysicistSaic Apr 2008 - Dec 2009Serving as Technical Lead for the Advanced-Development Team of NAVSEA's Surface-Ship ASW Simulation Trainer (SAST) Program and Primary Investigator for SAIC's R&D efforts on real-time simulation, I helped develop and field the first fully physics-based system for shipboard and school-house training on surface-ship sonar. I also provided R&D support for the award-winning Submarine Multi-Mission Team Trainer (SMMTT) and served as a subject-matter expert to the software-development team. As team-lead for R&D on the All-World Environment Simulation (AWESim), my role comprised development and implementation of algorithms for the simulation of propagation, reverberation, noise, and other ocean-acoustic phenomena in our real-time supercomputer-based architecture and also verification and validation (V&V) of the entire simulation system. ▪Analyzed and formulated methods for simulation of active scattering from wakes▪Developed framework and algorithms for simulation of reverberation using bathymetric synthesis▪Developed and implemented scientific evaluation process for AWESim based on Defense Modeling and Simulation Office (DMSO) recommended practices and led teams of software engineers in the V&V process.▪Provided scientific and technical support to the development team in areas including simulation of Doppler in active/passive targets and reverberation, utilization of submodels (CASS, DANM), target modeling, and signal-processing algorithms -
Research PhysicistNaval Research Laboratory Nov 2005 - Apr 2008Working primarily in sonar signal processing and active classification, I incorporated human psychophysics into single-ping classification algorithms used for broadband incoherent bistatic sonar systems. The impetus for this was a psychoacoustic experiment I conducted, my analysis of which led to a new understanding of the mechanisms by which listeners distinguish between sonar echoes. In this process I was closely involved with two large-scale international collaborations: NATO Undersea Research Centre (NURC) Joint Research Proposal: “Characterizing and reducing clutter for broadband active sonar” and The Technical Collaboration Program, Technical Panel 9 (TTCP MAR TP-9): Broadband Active Auralization. ▪Jointly led an international effort to improve active-sonar classification performance through human-mimetic methods▪Developed and implemented human-mimetic signal processing algorithms for sonar classification and auralization evaluation▪Designed and administered psychoacoustic tests and analyzed data using cognitive models▪Developed information-theoretic frameworks for modeling spatial hearing and perception of sound in rooms▪Established computer-numerical-control (CNC) milling facility for manufacture of randomly rough fractal surfaces▪Participated in international collaboration for planning and execution of Clutter ’07 sea trial

Nrc/Nas Postdoctoral FellowNaval Research Laboratory Jan 2004 - Nov 2005Building upon my experiences in scale-model measurement, I developed (together with Dr. Robert F. Gragg and Mr. Raymond J. Soukup) a unique capability for the fabrication of large-scale synthetic fractal surfaces suitable for validation of mathematical theories of scattering from rough elastic ocean bottoms. I later formulated and published mathematical and numerical models characterizing the behavior and performance of aspects of this facility. ▪Conducted experiments for and analyzed data from scale-model studies of acoustical scattering from rough elastic surfaces▪Created software for generation and analysis of 2D random fractal topography ▪Assembled computer-numerical-control (CNC) milling system for manufacture of randomly rough fractal surfaces▪Developed algorithms and software for estimation of fractal and spectral parameters of rough surfaces.▪Developed theory and made field measurements in support of acoustic/radar system for early detection of mortar and rocket launch

Research AssistantRensselaer Polytechnic Institute Jun 2000 - Jul 2003Working in the field of concert-hall acoustics, I developed and validated improved mathematical and computational models to address the pressing problem of predicting sound fields in coupled-room concert halls. As part of this work I introduced modifications to one of the primary commercial software packages used in room acoustics (CATT-Acoustic). These models have been broadly cited in the literature and widely adopted by the worldwide consulting community. The new insight and renewed rigor I brought to the problem led Leo L. Beranek to nominate me for the MacArthur "Genius" Award in 2004.▪Formulated mathematical and computational models of sound fields in rooms and systems of coupled rooms▪Designed and built, or oversaw construction of, a series of scaled-down physical models for acoustical studies▪Assembled acoustical measurement systems; conducted and analyzed acoustical measurements of rooms▪Developed research agendas for two weeklong concert-hall measurement experiments, with budget responsibility▪Advised graduate and undergraduate students on projects relating to auralization, electroacoustics, and psychoacoustics
