PROFESSIONAL EXPERIENCE
ROLLS-ROYCE CORPORATION:
CE Turbine Blade Design Engineer – Robust Design Lead
Indianapolis, IN
Turbine Component Design Engineer
Present
Currently working as a design engineer in the component engineering business unit supporting the development and implementation of
Robust Design tools and techniques in the design of turbine blades. I work as an accredited ASQ Black Belt with a specific emphasis in
Robust Design. I am leading a global implementation initiative on a key system known as GTDes which focuses on the automation of the
turbine blade analytical process with the intent of enabling multidisciplinary optimization and stochastic modeling. I also support, mentor and
lead projects relating to AE 2100D3 cost reduction efforts. Relevant projects the CE group includes:
 Stochastic shroud balance optimization
 Stochastic airfoil balance optimization
 Robust airfoil mass distribution optimization
 Genetic algorithm for optimal blade sort distributions
 2D topology optimization of turbine blade attachment
 Probabilistic working group for the application of Bayesian Networks
F136 LP Turbine Vane and Blades Design Engineer
Indianapolis, IN
Turbine Component Design Engineer
July 2010
Worked as the design engineer on three nickel based single crystal alloy low pressure (LP) turbine gas path components consisting of the
second stage vane, second stage blade, and third stage blade for the JSF F136 program between GE and Rolls-Royce. Experienced a multitude
of different analysis techniques requiring aero-thermal, mechanical, and structural dynamic assessments. I also worked closely on the
development and production of the parts with suppliers, assisted with assembly conformance, and oversaw testing. The program gave me a
tremendous amount of insight regarding aero-thermomechical analysis and structural dynamic high cycle fatigue while also obtaining skills
necessary to coordinate drawing changes and trouble shoot part development utilizing the Material Review Board (MRB) process with
suppliers.
Stress Rupture/Blade Sizing Tool
Indianapolis, IN
Turbine Blade Structural Analysis Intern
Summer 2009
Developed a fully functional stress rupture design tool for preliminary turbine blade sizing. The program has the capability to import several
different sources of data, update imported data, record outputs, and load recorded outputs. Also developed a second tool for extracting Excel
data based on my importing methods for the blade sizing tool. Both tools will be published for national use throughout Rolls-Royce North
America. This program was created in three months starting with no previous experience of programming in VBA.
RESEARCH/PROJECTS
EMBRY-RIDDLE SENIOR DESIGN:
PRIME Sat Research-Experiment Design
Prescott, AZ
Design Team Lead & Attitude Determination Sub-Lead
Fall-Spring 2009
Team lead of senior design students which developed an experimental microsatellite configuration to demonstrate the feasibility to
dynamically determine satellite inertia parameters in-orbit. A proposal was submitted to NASA with the intention of receiving a highly
competitive “free-float” position on the Microgravity University program. My roll was to lead the team and develop the mathematical
algorithms for inertia estimation using an extended kalman filter. The algorithm has the ability to estimate known inertia parameters from
simulated attitude data to within 10% and demonstrate a more accurate control response. The team’s proposal was accepted December 9,
2009 and the flight was June 24, 2010. The team completed a successful 10 day on-site research excursion and flight at Johnson Space Center
Houston, TX which ended with definitive results that the system was fully operational and the algorithm showed overall model convergence.
The final results were documented and submitted to NASA.
EMBRY-RIDDLE EXPERIMENTAL SPACE SYSTEMS DESIGN:
CubeSat Microsatellite Design
Prescott, AZ
Design Team Lead & Attitude Determination/Control Sub-Lead
Spring 2009
Lead a class of spacecraft design students through the process of developing functional subsystems into a fully operational 10 cm cube
microsatellite. Five design subsystems included: electrical power systems, on-board computer, attitude determination, structure, and
mechanical balance. I also lead the attitude team through design of theoretical and experimental modeling analysis in MATLAB and
interfacing of gyroscopic sensor with Picaxe 28X1 µ-controller on printed circuit board stack configuration. Final project was a success and
proved to be the first successful microsatellite development at Embry-Riddle Aeronautical University.
EMBRY-RIDDLE NASA SPACE GRANT:
CanSat Research Competition
Prescott, AZ
Lead of Structural/Descent Design
Fall 2008-Spring 2010
Team of four creating an approx. 8in by 2in “can satellite” to be launched 2000ft sustaining 20g shock and communicate telemetry to a
ground station including height, GPS location, and housekeeping information (voltage, power output, systems management), then landing
safely to communicate ground temperature. The project was funded by the NASA space grant at Embry Riddle. Out of 40+ teams that
entered only 27 could compete with a finished design. Out of the 27 only 5 operated correctly during launch (including the team’s design).
The team was awarded 4th place and international recognition. The team members then continued with the following years to mentor new
students through the design process.
HASP Research Competition
Prescott, AZ
On-Board Computer - Systems Engineer
Fall 2009-Spring 2010
Worked closely with a team of four to develop a payload for a NASA high altitude weather balloon that was designed to act as the life
monitoring system, power supply, and telemetry system for a research package being developed by Pima Community College in Tucson, AZ.
Working with the design team and trouble shooting coding, assembly, and testing errors was a valuable experience given the complexity of
the system and the team coordination.
University of Hawaii Orbital Analysis
Prescott, AZ
Lead Orbital Mechanist
Fall 2008-Spring 2009
Model a low energy sun synchronous orbit for the University of Hawaii in cooperation with NASA. The research consisted of modeling third
body perturbation effects, varying earth gravitational fields, solar forecasting, eclipse times, and space craft sunlight times throughout
maneuvers to more accurately predict the LEO satellite behavior. The satellite will be launched as the primary payload for the University of
Hawaii’s space research center.
