Summary
Using both Computer Science and Mechanical Engineering abilities, I have become an expert in Instrument Software Engineering. I have been successful designing efficient, real-time software control systems for mass spectrometry, holographic ultrasound imaging, and servo/stepper motor controls. At PNNL, with help from National Instruments Measurement Studio libraries, .NET development, real-time systems, and networking - I had development control for research projects on six IMS instruments, a TIMs instrument, an Ion Conveyor, and an Ion Funnel Trap. I received second authorships in several different technologies -- such as mass spectrometry, FAIMS, MRM, microfluidics, and smart LTQ-FT systems. At Advanced Imaging Technologies, I developed the interface and controls for a diffractive ultrasound tissue imaging system tested on over 180 patients. Prior to this, my background includes writing and designing motion control products used for manufacturing and another in wide format photo quality imaging, etc. Developing optimized, safety-oriented code has been a rewarding and exciting experience.

Experience
Proteomics research working on improving Mass Spectrometry, MRM, smart LTQ-FT, and microfluidics. I developed system automation, fractionation, fragmentation, multiplexing, etc with 8 ion mass spectrometers. As an Informatics engineer, I worked on smart LTQ-FT, system calibration for peptide alignment and received copywrite included in patents dealing with data visualization, compression, and storage. Using National Instruments, Acqiris digitizers, and .NET interfaces for most of the development. Other areas such as high-precision micro-fluidics, temperature, high voltage racks, system status, and system safety controls were under my development control. Designed, created, and directly assisted scientists at Bruker and Agilent. Increased abilities by helping the informatics group with SRM CE Optimization. I have received many complements and have enjoyed making toys for the PhDs in C# and C++.
* Recipient of 2013 R&D 100 Award for CoMet contributions, a 2012 Key Contributor Award, a Software Creator Award, and 4 performance awards. By 2013, I had 26 abstracts submitted, 11 journal articles, and 29 presentations as second author, and control software was copyrighted.
* Created department used IMS viewer for Ion Mobility experiments and helped with relational database architecture to store data. Viewer was used as example for Agilent software implementation.
* Mentored Washington State University students with computer science senior projects.
At a re-start company, I redesigned and developed the real-time software architecture and GUI for a Holographic Ultrasound imaging system (used for soft-tissue medical imaging) in C#/C++. My work saved the company up to $8000 per instrument and greatly improved scalability and usability. Wrote the user-interface, controlled 9 axis's of motion (3 servos, 6 steppers), a timer control card, TCP/IP remote imaging & system control capabilities, video enhancement of 12 bit images at 15 frames per second, and miscellaneous I/O (fill, lights, temperature sensor, leveling). I developed the acoustic lens formulas for focus/magnification, profile design automation, PID loops, and detector leveling formulas. Additional duties included system administration, and web site development.
Designed and developed engine to calculate nuclear waste volumes/composition using Crystal Ball statistical libraries. The system inventoried 75 analytes at 414 sites over 57 years, required optimization of both memory (max 1.3 GByte RAM) and speed (value convergence). Converted original engine from Delphi 4.0 to 6.0, then rewrote and upgraded the simulation code to Open Crystal Ball C# .NET. Using Microsoft COM technologies, Microsoft Excel was used to store inputs, store results, and create reports. Additional duties included analysis, mathematical derivation, verification, testing, and Perl/Windows scripts. I provided Macros, scripts, and system administration for office as well.
Developed embedded, real-time industrial automation servo motor applications. Designed software using C++ object oriented programming. I led Electronic Gearing Project, Infinite/Finite Impulse Response (FIR/IIR) Position Filtering which reduced customers design complexities and solved a wide range of applications. I worked on debugging/improving communication protocol used for servo motion profiles with proprietary, interpreted pseudo-code. Performed High Precision Integer Analysis and System Simulation. I completed full cycle software design -- Wrote Software Requirement Documents, Software Design Document, Qualification and Accuracy Testing. Developed new debug and data acquisition tools used by entire team allowing increased coding efficiency and simplifying verification of system performance.
Researched and developed embedded, real-time patented, large-format, photo-quality printers. I worked directly with Mechanical & Electrical Engineers and became motion control expert for dynamic control of servo and stepper motors. Developed and tuned closed control loops for servo motors (Positional, Integral, Derivative control), Used various feedback devices such as encoders, tension, etc. producing accuracy in position to within 1/600th inch and velocity to within .05 in/sec. Developed open control loops for stepper motors required for mostly precise accuracy in position. Also, wrote routines and modeled synchronization of servo to stepper, stepper to servo for use in dynamic tension control of fabrics. Performed system modeling, safety controls (watchdogs), human interfaces, error trapping with automated correction and system initialization.
