EMPLOYMENT HISTORY

INGERSOLL RAND, Indianapolis, IN 2009 - Present

Staff Engineer (Simulation team leader) and Project Manager

UNITED TECHNOLOGIES, CARRIER CORPORATION, Indianapolis, IN 2004 – 2009

Staff Engineer (UTC ACE Associate)

Oversaw structural design and specification verification tests for development projects focused on residential and

commercial applications including new product and component design, health monitoring, and implementation.

• Performed modal analysis, transient analysis, static analysis, stress analysis using Finite Element Analysis (FEA)

packages (ANSYS and Hypermesh) resulting in lower development costs and improved product performance.

• Performed nonlinear analysis such as bulking analysis, large deflection analysis, and stress analysis using ANSYS.

• Established several company-wide test procedures to determine the structural integrity of components resulting in

higher performance components, delivering more consistent reliability with 25% claim reduction. Tests included:

sound intensity measurement and analysis, sound power measurement and analysis, modal analysis, and vibration

measurement and analysis, stress analysis, nonlinear analysis, and life test.

• Health monitoring of motor, motor housing, compressor health using LMS Test.Lab and B&K Pulse.

• Electromagnetic analysis on AC (PSC) and DC motors (ECM) to reduce vibration and acoustics radiation by 10

dBA

• Developed comprehensive knowledge in designing, performing, analyzing and reporting multiple structural,

thermal, stress and strain tests; recognized subject matter expert within organization.

BOSCH GmbH, Shanghai, China 2001

System Engineer

Led new product design team to develop hybrid technology which met Original Equipment Manufacturer’s

requirements staying within $13 million budget and completing design effort in one year.

• Developed EMS (Engine Management System) for gasoline and LPG (liquidized petroleum gas) technology to

be used in hybrid engines.

• Performed modal analysis on engine components and vehicle frames using ANSYS and NASTRAN.

• Performed vehicle interior noise analysis using ANSYS.

• Performed vehicle structure-fluid interaction analysis using ANSYS.

VOLKSWAGEN GROUP/TONGJI UNIVERSITY 1998 – 1999

Product Engineer

Supported product development group by providing structure simulation and testing service.

• Identified vibration transfer path providing information for component redesign resulting in 40% reduction of

overall vibration and noise level.

• Analyzed structural integrity of automotive parts based on Finite Element Analysis (ANSYS) and Statistic Energy

Analysis (SEA) methodologies providing design improvement opportunities in the mid- and high-frequency

ranges.
