EXPERIENCE 4/1998 - Present Phoenix Analysis and Design Technologies (PADT – An , Inc. Partner), Tempe, AZ Consulting Engineer 8/2011-Present Arizona State University, Tempe, AZ Adjunct Professor Software Design/ programming 1/2012 • HIFFA (Honeywell Ion Fusion Formation Automation) : Custom software written for Honeywell Aerospace for the automation of Ion Fusion Formation (IFF) numerically controlled part creation technology. Software written in C++ (interface in MFC) to generate simple primitives. More complicated parts created with composition. 1/2003 • Modal Extraction Parallelization Scheme: Internal use only. Vertical application for ANSYS which breaks mode extraction into frequency bands to be solved on different computers. The code compresses eigenvectors in “blocks” on different computers. Mode superposition code also written to be centralized or decentralized (to superpose eigenvector blocks in parallel) . This code was successfully used to solve a system consisting of 1.2 million DOF’s and over 1000 modes using ANSYS. Written in C and APDL. 3/2002 • XPSD/STAT: Internal use only and under evaluation by an overseas ANSYS partner. ANSYS vertical application for finding the statistical properties of the von Mises stress for random vibration problems solved using xPSD (below) using the non-stochastic Siegalman/Reese method (documented in International Congress On FEM Technology – 2002 conference proceedings). Written in C and APDL. 8/2002 • XPSD: Commercial software (see http://www.padtinc.com/support/freesw/ ). ANSYS vertical application for solving single random base-excitation problems using the Large Mass Method (LMM). Written in C, C++, and APDL. See ANSYS 2002 Users Conference and Exhibition – conference proceedings 6/2002 • Autocontact: Software written for ANSYS, Inc. to automate the detection and creation of contact surfaces in multi-part models. Written in C and ported to all platforms ANSYS supports. 7/2001 • TAG (Turbomachinery Airfoil Generator) : Internal use for Honeywell Engines and Systems. Stand-alone application for parametric turbine/compressor blade design using NURBS curves and surfaces. Written in C and TCL/TK on HPUX 10.0 platform Commercial FE Simulation 8/2008-Present • Currently in charge of most structural analysis tasks(elastostatic, elastodynamic, thermal) of new helicopter power turbine for a major US defense contractor

6/2003 • Automation of equivalent orthotropic material development for integrated circuit board – ANSYS Simulation and APDL scripting. Simulation consisted of multiple linear static analyses to obtain equivalent orthotropic properties of continuous material. Necessary simulations were scripted in APDL and delivered to customer for future use. 8/2004 • Automation of rotordynamic analysis – ANSYS simulation and APDL scripting. Developed a parametric design and analysis tool for rotor-bearing systems (specifically for the design of turbomolecular pumps). The script performs pre-stressed modal analysis, generates Campbell diagrams, and performs harmonic response analysis. Varian, Inc. 3/2004 • Projectile sand impact analysis – ANSYS/LS-DYNA simulation. Nonlinear sand impact study of projectile assembly. Sand was modeled as EOS material on an ALE grid – Talley Defense 10/1999 • Flapper tool – ANSYS/LS-DYNA custom tool for parametric building and simulation of turbine flapper valve assemblies. The tool parametrically creates a hex-meshed multi-part assembly in ANSYS, which is then analyzed for valve opening/closing impact stresses. The entire process is automated and parametric studies easily conducted – Honeywell Aerospace FE Course Design and Instruction 8/2011 - present • MAE 323 - Computer Aided Engineering II. Introductory finite element analysis using ANSYS. Taught at ASU. Course material can be viewed at www.padtinc.com/mae323 7/2007 • Introductory Structural Dynamics with ANSYS – Course material covers, modal (eigenvector, eigenvalue extraction) analysis, harmonic analysis, transient structural analysis, spectrum analysis, and random vibration analysis. Funded by the Arizona Job Training Program 3/2003 • Complete Dynamic Simulation of Avionics Box Designs in ANSYS. Instruction includes pre- stressed modal extraction, frequency-domain shock spectrum analysis, harmonic response, PSD, and full transient response in time domain with LS-DYNA. General Dynamics Decision Systems 9/2002 • Random Vibration Analysis Training Course – Developed and taught comprehensive random vibration course using ANSYS and xPSD. Course emphasized calculation of von Mises stress values for use in fatigue – Raytheon Missile Systems Product Design 2/2004 • Automotive fuel cell endplate design – Designed endplates for automotive fuel cell to minimize thermal mass while maximizing stiffness. Design was optimized in ANSYS prior to finalization – UTC Fuel Cells 7/2005 • Miniature fuel cell/battery hybrid power source – Designed entire power system to minimize mass and volume while maximizing power output. Various components were analyzed in ANSYS – U.S. Army grant 8/1999 • Ionized plasma vapor deposition chamber – Responsible for CAD design, component acquisition and manufacture, and adherence to company specifications .– Tokyo Electron Arizona
