As contractor via Bill Austin and Asso., working with the Hardware Integration group of the Emission Solutions division of Cummins; educated, evaluated and improved diesel exhaust emission sensor capabilities. Awarded patent https://patents.google.com/patent/US20170268979A1/en on sensor life extension. Acted as a complete solution expert, working from early stage innovation to in-field troubleshooting, with sensor related issues. Provided expert advice, studied and reported on highly challenging chemical sensor issues. Evaluated several hundred patents on potential technologies. Attended Pittcon and The Electrochemical Society meetings to evaluate the nature of current understanding and the potential for future developments directing future activity.Specific sensors were particulate matter (PM), Nitrogen Oxide (NOx), and ammonia (NH3). The PM is a simple interdigitated electrode resistance measuring device, the difficulties came about due to diesel exhaust poisoning conditions. Developed an innovative testing method for corrosion reactions, much less expensive than previous methods.The NOx sensor is a two chamber, multistage electrochemical reactor. Poisoning and thermal issues were continually improved. Significant changes implemented on requirement definition. Performed extensive analysis of head to tail swab sampling of four diesel trucks via swabs and EDX. Determined several significant new chemical pathways for poisoning and analysis techniques.Created educational materials. Over six months, wrote a technical document (30,000 words) on practical aspects of bringing sensors into the diesel exhaust system. Sections included: Failure thinking design (iDFMEA), Chemical Compatibility, Sensor Corrosion, Operating Conditions, Failure Analysis, Location, Ceramics, and an example. Developed innovative proposals involving system engineering, knowledge transfer, FMEA, and troubleshooting.

Provided company wide electrochemical needs for medical device sensors. Performed a full characterization of the weak acid sensor technology that is a significant profit base. Managed chemical aspects of newly purchased alkaline oxygen sensors production line. Harmonized specifications with industry standards. Improved the testing and QC procedures. Part of QC was bringing technician derived best practices into the standard operating procedures with tests and documentation. With significant financial constraints, I was able to launch two new products. Designed and developed extra stable oxygen sensor. Developed an education kit to teach about electrochemistry. Standard medical device procedures such as FIMA and clinical reports were part of my duties. Supported safety committee.

As contractor via Aerotek, I researched and developed solutions to the slow kinetics of a novel liquid crystal transduction sensor technology (NO2). Identified the root cause which was unable to be modified in the current system.

As a student worked ¾ time to set up a suite of analytical instruments evaluating the feed and results of mini and average pilot plants turning coal like materials into methane. Instruments were GC, GC/MS, TGA, CHNS, PSD. Improved LECO 630-100-400 CHNS instrument down time by 50%.

Lead engineer on an instrument to concentrate chemicals from the air into water by approximately 100,000 times. This was essentially a mini static precipitator running at 20,000 volts. Over the course of the two year contract w/ the Army we dropped the power consumption 50%, noise by 70%, and increased the efficiency 50%. Www.breathkey.com this small startup developed a retail alcohol breathalyzer. Developed novel inexpensive ethanol sensor ($2.50 vs $25 production costs), two electrode electrochemical type, using conductive and insulating plastic. Client stated “Without this sensor the product could not get out the door, no one else is anywhere close to this cost.” Developed complete manufacturing system based on shuttles that hold the molded bodies from start to finish. This system was designed to be easily scaled up with inexpensive tools and fixtures. Pat # 7060652. As of 2015 this manufacturing system and sensor are still in use and have been expanded to CO sensors (http://www.detectcarbonmonoxide.com/). Performed development and set up manufacturing system of novel conductive and insulating plastic carbon monoxide sensor. Over the years spent about 1/3 of time and money on testing and QC. Dropped reject rate down to less than 0.01% and costs as low as $4/sensor for production (including platinum catalyst).
