Mr. Keller is directly responsible for creating highly advanced Software Architecture, embedded programing, IT solutions, and cloud-based solutions using Azure. As Director of Software Engineering he is also responsible for daily staff meetings, identifying programmable logic and processor functional blocks using the Xilinx ZYNQ RF System on Chip (RFSoC), embedding the code needed on the RFSoC, and creating software to maximize the capabilities of the PenTek QUARTZ 5950 board.

Mr. Keller was employed by Southwest Research Institute (SwRI) as a Principal Scientist. He was responsible for designing and building a one-of-a-kind Advanced Electronic Warfare Laboratory (AEWL) prototype. The purpose of the AEWL was to generate a complete spectral environment including radar, emitter, and other various signals to allow testing of new radar and SIGINT systems. To accomplish this task, Mr. Keller needed to oversee several subcontracts and SwRI personnel. Upon completion of the AEWL Mr. Keller transitioned the system from a prototype to a fully functional system. Mr. Keller created a passive tag using a MSP430 microcontroller that would modulate between two frequencies allowing the power from a backscatter radar to be returned as an FSK signal that could be demodulated by the radar. He also created the FSK demodulation algorithm used on the radar FPGA. Additional projects include spectrum coverage and usage, use of Van Atta antenna to capture geographical, and detection of substation failure using RF. Other duties during his tenure as a Principal Scientist included writing white papers, acting as principal investigator, writing proposals, acting as the face of the company during client meetings, personnel management, project management, and acting as a CMMI 1.3 and 2.0 appraiser.

As a Senior Research Scientist at SwRI Mr. Keller worked on a number of distributed system components. His work with the Automation and Distributed Systems help couple a World Wide Web application with an Oracle data base using Hibernate to provide compatibility and persist the data. He also worked with the Applied Physics Division to create a dynamic linked library using C# to address communications, message marshaling and un-marshaling, and a variety of algorithms to enhance performance.Mr. Keller has completed two Internal Research (IR) Projects to expand the baseline understanding for Software Defined Radio (SDR). The most recent was a co-venture with the Aerospace Electronics Department incorporating a field-programmable gate array (FPGA) thereby allowing replacement of the waveform application dynamically. The previous IR conducted by Mr. Keller had established a thorough understanding of the Joint Tactical Radio Systems requirements defined by the Software Communication Architecture.

As a Research Scientist Mr. Keller’s embedded work has included building systems using the TI MSP430 family of semiconductors in which a handheld device was created to control, monitor, and program several remotely located data collectors. The handheld device also had to interface with a standard PC to accept data and programming. In the Aerospace Electronics Division Mr. Keller worked on the embedded systems of the A-10 Aircraft Monitoring System and Turbine Engine Maintenance System to enhance the monitoring features for the A-10 aircraft’s 1553 buses and Turbine Engine Monitoring/Aircraft Data Recorder (TEMS/ADR).

As a Research Analyst Mr. Keller was project manager of the B-1B Armament System Trainer (AST) Block E Upgrade; including managing funds and schedules and analyzing aircraft changes which had to be duplicated in the simulator to maintain concurrency. As lead software engineer on the Upgrade, he created a high-level language which gave instructors the capability to change simulator graphical user interface without reprogramming the entire trainer.Mr. Keller worked with AF personnel to create a new tool, Grades Allocation Model (AFGAM), to calculate manpower needs AF wide. AFGAM uses a web-based interface, written with JAVA and JSP, to access an Oracle database. Mr. Keller developed all aspects of the database, linked the newly created database with legacy databases, and wrote SQL statements that would extract the data using a JDBC interface.

The newspaper was transitioning through major format changes, which was a challenging and demanding programming experience. Operations could not shut down so all technical aspects were critical during transition. The successful function of the newly programmed format, completion of the transition ahead of schedule, and detailed documentation for future reference opened opportunities for greater challenges within the company. 1. Format all API and up wire stories for daily newspaper using Fingerpost for drag and drop entry into page templates.2. Convert scripts to C or C++ for more rapid execution of programs.3. Maintain several UNIX servers to ensure daily newspaper was published.
