Managed a team of 3-5 engineers, drove performance against schedule, planned and delegated work, and provided review and feedback. Developed the following models for the C++ 6-DOF simulation: aerodynamics, propulsion, structural dynamics, atmosphere, IMU, staging, and thrust vector control. Oversaw the verification & validation process for select models. Wrote V&V plan documents based on MIL-STD-3022 for verification, validation, and accreditation of models and simulations.

Redesigned and streamlined the calibration and alignment model in Simulilnk and C++. Designed, evaluated, and improved synchronous and asynchronous thruster control algorithms for spacecraft attitude control. Used Monte Carlo analysis to evaluate tradeoffs between control algorithms to reduce fuel consumption and improve accuracy. Researched and implemented a control algorithm for load relief at max-Q during launch.

Performed stability and control analysis to inform the design team for the final outer mold line selection and control surface layout. Selected the control surface actuators based on hinge moment analysisDeveloped a nonlinear 6-DOF simulation and control laws in Simulink. Integrated a Piccolo autopilot system with the simulation in order to support control law tuning and flight test.

1. Independently wrote Matlab codes to study simulation data in order to define requirements, and created the final report with recommendations to senior engineers. 2. Reliably delivered flight test summaries within a fast-paced testing environment, helping engineers quickly begin analyzing the data. The reports presented the test data in a clear format and highlighted the performance of the flight control systems.3. Assisted several engineers with a ground vibration test, adapted Matlab scripts to process the test data, and contributed to the report describing the results.4. Conducted research on the aerodynamic characteristics of a V-tail and submitted findings to engineers to revise and improve an existing analysis tool.5. Assisted with organizing and presenting requirements documentation to engineers both within and outside the department. 6. Delivered a technical presentation to coworkers and managers summarizing projects.

1. Worked as a researcher and tech writer on the MQ-1B Predator flight manual and checklist.2. Conducted research on new developments of the Predator UAV3. Worked with test engineers and pilots to determine if results related to the flight manual.4. Communicated with maintenance and integration engineers for the most up-to-date information about changes in Ground Control Stations.5. Developed updates to the flight manual regarding Ground Control Stations.
