• Performs financial, personnel and technical management for the Branch. • Responsible for business development including capability briefs, white paper creation, and proposal writing.• Coordination of personnel assignments to align technical and leadership skillsets to meet project needs and to establish, maintain and forecast staffing. • Provides oversight to major programs technical direction and Subject Matter Expertise across GTRI.• Responsible for setting up and managing physical laboratory space including procurement and management of test and measurement equipment.• Coordinates with Georgia Tech and GTRI Labs to provide expertise and staffing support from the Techniques Branch.

The goal of the Embedded System Cyber Security course is to examine and assess the existence of cyber security issues found within IoT hardware devices. These devices range from in home security cameras, police cameras, smart garage doors and building management systems. In order to achieve this, we will implement a multi-domain investigation through the use of hardware reverse engineering, software/firmware reverse engineering, and RF analysis along with static and dynamic testing through instrumentation. Finally, any identified vulnerabilities in the devices' cyber security protection will be tested and demonstrated.

Reverse engineering and troubleshooting of a VXI based dual down conversion super-heterodyne receiver used on a cryptologic communications system for the Navy. Developed the test to fully characterize each unit to identify potential problems and reverse engineered the receivers down to the schematic level. Created spread sheets to collect the data taken and identify trends in. Led and trained a team of engineers to streamline the characterization, identification, and repair of each receiver. Worked with technicians to replace failing parts to reach the continued goal of getting each unit working properly and back in the field.Lead engineer to produce an expanded version of a threat analysis program based on and originating from my thesis work as mentioned above. JACKAL (Joint Analysis Countermeasures Knowledge Assessment Library) was a requirements study for an application to share EW capabilities in order to improve aircraft survivability. Using JACKAL, a user can identify alternative solutions to a specific EW system shortfall by leveraging information on fielded systems and/or new technology development across the DoD. JACKAL would act as a single access point for existing DoD EW data sources, including system capabilities, characteristics, operational assessments and information POCs. This study provided me the opportunity to attend multiple EW conferences across the country and to visit multiple EW organizations across the DoD. A major component of this study required us to interview EW experts (RF/EO/IR) to gather requirements for a final product.A demo version of this software tool was created and delivered to the Air Force. My role included ensuring all the requirements were met, the tool was functional, and to develop the math formula for the interactions between the entities.

Designed and built multiple lab test stations to allow for these systems to be fully operational inside of the lab therefore providing the ability to perform integration testing and troubleshooting at the unit level. Monitoring and sampling of signals was made available so both the control signals and the RF signals (threat and jamming response) signals could be monitored without interruption.These systems represent a jammer, a receiver, and a system that is both transmit and receive. My role on this task was the lead engineer which consisted of the overall system design, assisting junior engineers with the details, managing the BOM and ensuring cost and schedule were met.Lead an effort to find a replacement for a detector and amplifier section of a direct tune RF receiver. I fully characterized and specified the requirements for this section of the receiver. In my research I found that it would be more cost effective and require less maintenance if we combined multiple circuit boards into a COTS detector log video amplifier (DLVA). The new unit far exceeds the requirements based on the legacy design and is currently deployed in multiple aircraft.

Supported multiple projects in their attempt to pass MIL-STD 810 environmental and MIL-STD 461 EMI/EMC testing. Roles have included writing and proofreading test plans, creating schedules, executing the tests, troubleshooting and repairing units that fail.
