PROFESSIONAL EXPERIENCE

Teledyne Brown Engineering Huntsville, AL

Contract Position in Structural Analysis 2013

Performed stress and dynamic analysis of MUSES, an earth-pointing platform that provides accomodations

for payloads, attaches to the ISS and launches on the SpaceX Dragon. Reviewed all launch and on-orbit

structural requirements. Performed design optimization to meet frequency and low-risk or fail-safe fracture

control classification requirements for all primary structure and components. Generated mass properties.

Performed design optimization using Pro/Mechanica, and a correlated dynamic analysis using FEMAP and

NASTRAN for model delivery of Couples Loads Analysis (CLA). Recovered MUSES system level loads for

use in testing of components. Presented results at CDR.

ITT Power Solutions West Springfield, MA

Contract Position in Structural Analysis 2011 to 2012

Performed structural analysis of a High Power Alternator and Regulator, including static, modal, random

vibration, sine vibration and shock analysis, to MIL-STD-810 specifications. Performed thermal analysis of

the High Power Alternator and Regulator including conduction and fluid flow using CFDesign’s motion

module to obtain fan, impeller and system performance curves

Carnegie Mellon University – Robotics Institute Pittsburgh, PA

Visiting Research Fellow 2010

Performed structural analysis of the Rover and Lander structures for the Lunar X Prize project, including

static, modal and random vibration. Generated mass properties and requirements documentation. Performed

trade studies and design optimization for both metallic and composite materials. Performed on-orbit and

lunar thermal analysis of the Rover and Lander structures using Thermal Desktop and SINDA.

Analytical Services & Materials at NASA Langley Research Center Hampton, VA

Stress Analysis Group 2007 to 2009

Performed detailed stress analysis and sizing of various components and assemblies (welded and bolted

joints). Generated mass properties. Reviewed requirements and environments/loads documentation.

Performed random vibration, sine vibration and transient analysis of various components and fasteners.

Developed vibration test plans including test requirements, accelerometer placement and data recovery.

Verified analysis results with test data. Presented analysis results at Critical Design Reviews, Test Readiness

Reviews and Pre-ship Reviews. Documented final analysis results in formal reports.

NASA/Jet Propulsion Laboratory Pasadena, CA

Contract Position in the Design Group 2002 and 1994 to 1996

Performed trade studies and design optimization of the Mars Pathfinder spacecraft. Optimized the structure

for minimum weight, maximum frequency and positive margins to buckling, static and dynamic loads.

Performed analysis of primary and secondary structure including detailed models of the interface plate,

aeroshell, lander and the integrated assembly. Performed analysis of the PSI telescope, the meso-gyro

assembly and the Cassini spacecraft. Supported the project manager of the Near Earth Orbit Flyby

Configuration Second Generation Microspacecraft (SGM) s conceptual design with trade studies and design

optimization including a detailed mass properties report and a final analysis report.

Provided support for the design and analysis of Mars Exploration Rover components using Pro/ENGINEER

and Pro/MECHANICA. Created Pro/ENGINEER parts, assemblies and drawings used for conceptual studies

of future spacecraft.

Hughes Electron Dynamics / Space and Communications El Segundo, CA

Contract Position in the Stress Analysis Group 1996 to 2001

Completed trade studies of the XIPS Ion Thruster design. Generated a detailed mass properties report.

Completed static and dynamic stress and response analysis of XIPS (flight and test configurations) using

Pro/MECHANICA. Completed conduction and convection thermal analysis of XIPS using Pro/MECHANICA.

Completed thermal radiation analysis of the XIPS using IDEAS. Results of the dynamic analysis were used

during the qualification test to determine the notching procedure. Completed the verification of analysis

results with test data which showed very good correlation. Supported the acceptance vibration test of over 10

XIPS flight units. Performed thermal, static and dynamic analysis of several Traveling-wave Tube (TWT)

configurations consisting of over 10 different materials. Completed stress and dynamic analysis of several

satellite components and assemblies including antennas and feed lines.

Rasna Corporation (PTC) San Jose, CA

Technical Support Department 1991 to 1993

Provided customer support regarding installation and use of stress, dynamic, thermal and mechanisms

analysis of the Pro/MECHANICA software tool. Conducted various training sessions of Pro/MECHANICA

structural, thermal and mechanism analysis.

TRW Corporation, Space and Technology Group Redondo Beach, CA

Dynamics Department 1989 to 1991

Developed dynamic models for stowed and deployed TDRS satellites using NASTRAN and PATRAN.
