Objective
An experienced professional position that accounts for my technical interests in aerodynamics and propulsion flight science disciplines, utilizes my engineering background and expertise in computational methods, and accommodates my aptitudes in research and design within the aerospace industry.
Employment History
Aerodynamics-Propulsion Research & Development Engineer 04/2004 - 02/2010
Lockheed Martin Aeronautics Company
Palmdale, CA
Supported several ongoing and legacy programs in addition to internal research and development pursuits at Lockheed Martinís Advanced Development Programs (Skunk Works) facility in Palmdale, CA with aero-propulsion performance and computational fluid dynamics engineering analyses. Designed supersonic inlets and nozzles using method of characteristics-based inverse design tools, provided aero-propulsion flow analysis with CFD numerical tools, evaluated design candidates at wind tunnel test facilities, and optimal concepts were integrated into several innovative vehicle designs. Examined installed engine performance with a variety of analysis tools for integration into overall vehicle propulsion systems. Results and engineering assessments were documented and presented to program management, colleagues, and customers. Supported Lockheed Martin Aeronautics Company innovative technology development in plasma actuator flow control. Co-developed Lockheed Martinís proprietary 3-D Magnetogasdynamic finite differencing code, ENS3D. Features developed include electromagnetic physics coupled with a fully 3-D Navier-Stokes solver, MPI memory management for distributed computing envi-ronments, and an explicit dual-time stepping Runge-Kutta scheme for unsteady flows. Provided various numerical Magnetogasdynamic parametric analyses for dielectric barrier discharge flow control technology maturation to external aerodynamic and propulsion flowpath surfaces.

2007 National Medal of Technology and Innovation Laureate Winner Ė award recognizes those who have made lasting contributions to Americaís competitiveness, standard of living, and quality of life through technological innovation.

Holds Current DoD Top Secret Clearance
Advanced Propulsion Integration/CFD Engineer 10/2002 - 04/2004
Lockheed Martin Aeronautics Company
Fort Worth, TX
Supported current developments in active and passive flow control technologies for propulsion research applications in Lockheed Martinís Advanced Development Programs (Skunk Works) by providing computational fluid dynamics and computer-aided engineering analyses for a variety of DOE and parametric studies. Various propulsion CFD-related tasks required working knowledge and extensive use of both CAD and CFD tools. Tasks included time-accurate, flow control specific, and complex meshing tasks in order to obtain solutions. Documented and presented engineering results and recommendations to program management and colleagues.
Graduate Teaching Assistant 08/2000 - 08/2001
The University of Texas at Arlington
Arlington, TX
Prepared lessons, provided instruction, graded studentsí papers, and kept grade records for the Mechanical and Aerospace Engineering Departmentís MAE 2381 Experimental Methods Laboratory. Lessons were prepared for each meeting in order to provide students with hands-on instruction in performing numerous experiments that familiarized students with the use of several tools occurring in experimental work. Various physical engineering and scientific theories were validated throughout the course of this lab. Studentsí papers were graded offering feedback, and a record of studentsí grades was kept for an overseeing professor. Coordinated and assisted the supervising professor to overhaul every aspect of the laboratory. New equipment was purchased, assembled, implemented, and a new lab manual consisting of completely different lab work was written to improve studentsí lab experience.
Education
2000 - 2002
The University of Texas at Arlington
Arlington, TX
M.S. - Aerospace Engineering

Masterís Thesis Research comprised of designing, machining, and testing an Ejector-Augmented Pulsed Detonation Rocket (PDR) model integrated into an existing supersonic wind-tunnel facility. Work was completed in order to compare and validate CFD results and determine the effects of incorporating an ejector into an unsteady flow environment. The complex nature of such shock-driven flows necessitated this experimental approach. Experimental results were used to calculate a traditional performance parameter, the ejector augmentation ratio, for comparison to a value derived from CFD results and to evaluate the practical performance advantages in utilizing ejectors in future Pulsed Detonation Engine applications.
