      • 2017 - 2018

      Led implementation, simulation validation and testing of control software to improve transient capability on GE’s gas turbines ensuring ROCOF (ability to survive a fast, significant grid frequency event) and POR (Gas turbines ability to deliver a required amount of power during a grid frequency event) compliance per Irish and Northern Ireland grid requirements.• Improved POR capability as well as Fuel and Air Control during high ROCOF events. • Ensured timely delivery of new compliant controls software to sites becoming a key team player providing inputs and working with multiple teams.• Improved cycle time introducing a new step in the ROCOF evaluation process to have a few select, high risk official ROCOF cases approved by systems and electrical teams before completing all the simulations thus avoiding re-work.• Reduced handoff errors and delays by learning and completing all official simulations within the Grid Controls team.

      Developed, simulated and analyzed structural dynamic piping models for heavy duty gas turbines in the 50-250 MW range. The role included the design of piping systems in Fire Protection, Atomizing Air, Purge Air, Fuel Systems, Water Injection and Cooling and Sealing Air.• Transformed piping design standards immune to project variance factors, eliminating all scheduled Engineer and Designer time and decreasing defects due to human touch time.• 100% on time delivery record with zero defects due to piping code misses.• Eliminated major defects in the NPI (New Product Innovation) design process before hardware delivery to customers. Implemented more rigorous NPI design checks by developing a software tool to support process.

      Sprawled-posture insects exhibit a remarkable ability to rapidly run in a stable manner over complex terrain, a feat that has yet to be equaled by man-made legged robots. Extended reduced order model for lateral plane locomotion by developing leg positioning and actuation strategies that are consistent with insect leg function in experiments. • Improved locomotion performance of the model in terms of gait stability and robust response to external perturbations, such as those encountered in running over rough terrain.
