Studied climate mechanisms through the physical and chemical analysis of polar ice cores. Managing ice core projects typically involves multiple institutions, multiple analytical techniques, and tens of thousands of samples requiring high attention to detail and organizational skills. Results and conclusions are communicated via (co-)authorship of peer reviewed journal articles and conference presentations. * Significant Laboratory Accomplishments o Managed the start-up of a new ice core laboratory and walk-in freezer facility that successfully processed and analyzed three multi-institution ice core projects. - SPICEcore: a 1750 meter ice core extending 54,000 years including 1 cm ion chromatography sample resolution throughout the Holocene and successful processing and analysis of the brittle ice zone. https://spicecore.org// - GreenTrACS: a series of 16 firn cores from the Western Greenland percolation zone investigating recent accumulation and melt changes. http://greentracs.blogspot.com/ - Denali Ice Core Project: a pair of parallel ice cores from Mt. Hunter, Alaska detailing accumulation change over the past 1,200 years. o Led the design and development of a high-resolution Continuous Flow Analysis ice core melting system integral to the analysis of more than 150,000 individual samples. o Trained and provided mentorship for up to 12 undergraduate and graduate students per quarter to provide lab labor. o Responsible for data management and quality control.* Responsible for the installation, maintenance, and training of lab instruments (ion chromatographs, water isotope analyzer, particle counter, liquid conductivity).* Participated in the interpretation and dating of all ice cores via annual layer counting and volcanic event matching.

Results and conclusions are communicated via (co-)authorship of peer reviewed journal articles and conference presentations. * Significant Laboratory Accomplishments o Designed and implemented improvements to a Continuous Flow Analysis-Ion Chromatography melt system that increased system reliability, robustness, and sample resolution. o Managed multiple ice core projects from sample preparation and chemical measurements to data management and analysis. - WAIS Divide: analyzed two firn cores (244 m total) and the entire brittle ice zone (723 m). http://www.waisdivide.unh.edu/ - South Pole Project: Analyzed a series of shallow cores used to develop and publish an 1,830 year volcanic record and study sulfate sulfur isotope anomalies. - Dome A: Collaborated with Chinese to analyze a shallow ice core and develop a 2,840 year accumulation history and volcanic record.* Responsible for installation, maintenance, and training of lab instruments (HPLC, IC, GC-MS).* Participated in the interpretation and dating of all ice cores via annual layer counting and volcanic event matching.

Led and participated in teams responsible for the design and implementation of particulate and gas filtration systems used in the semiconductor, copying, and printing industries.* Key Accomplishments o Development of improved sorbent material for semiconductor fab gas filtration. o Developed experiments to analyze performance and life expectancy of filter materials.* Regarded as technical expert on gas filtration materials used in semiconductor fab facilities.* Patent: Keller; Scott A., Schneider; Kirk A., Carey; Todd G., Ferris; David G., Stack Filter Assembly and Methods, US Patent 6,093,237, Donaldson Company, Inc., July 25, 2000.

Evaluated and specified all adhesives, sealants, coatings, and wood preservatives used in the manufacture of window and door products.* Led and participated in cost improvement, quality improvement, and new product projects within cross functional teams (engineering, manufacturing, purchasing, and marketing groups).* Key Accomplishments o Led successful introduction of superior performing urethane sealants and adhesives into new and existing window designs. o Teamed with vendors, marketing, and manufacturing to implement high performance coating systems for aluminum extrusions and roll coated coil.* Provided technical expertise for adhesive, sealant, coating and wood preservatives to manufacturing, distributors, customers, engineering, and marketing groups.
