CHROMATOGRAPHY. For the past 35 years, expert has specialized in many different sub-fields of chromatography, including HPLC, reversed phase LC, gas chromatography, affinity chromatography, and ion chromatography. He has published extensively in all of these fields. Additionally, he has pioneered fast liquid chromatography especially gradient elution and multi-dimensional LC.

CALORIMETRY. Expert has done a great deal of research in thermoanalytical chemistry (DSC, thermometric titration). He has approximately 30 papers in this field.

FLOW INJECTION ANALYSIS. Expert has published many papers on flow injection analysis, particularly in conjunction with the use of enzymes.

ORGANIC SOLVENT. He has published a number of papers on the study of physical and chemical properties of organic solvents. He is especially interested in the phenomena of solvent effects on spectra, rates, equilibria, and phase separation.

CHEMICAL SEPARATION; BIOCHEMICAL SEPARATION. Expert has done a great deal of research on the thermodynamic and kinetic factors involved in adsorption, diffusion in fluids, and ion exchange (cation and anion).

ELECTROANALYTICAL CHEMISTRY; TITRATION. Expert has published a number of papers on ion selective electrodes, immobilized enzyme electrodes, and titration. He is an expert in the area of acid-bore chemistry. He has extensive experience in conductimetric analysis, polarography, potentiometric analysis, voltammetry, and analysis of organic functional groups.

CHEMICAL ANALYSIS. Expert has published papers on chemical analysis of inorganic and organic species by both GC and HPLC, atomic spectroscopy, enzyme analysis, and especially trace analysis.

ENZYME IMMOBILIZATION. Expert has published many papers on the use of enzymes and immobilized enzymes in chemical analysis. He also has published a book in this field.

Expert was a consultant for nearly 25 years for a major manufacturing company located in the Twin Cities. He regulary consulted on problems related to chemical processing and chemical analysis. Also served as a sounding board for new business ideas. He has been a consultant for nearly 10 years for a major chemical measurement instrument manufacturer that specializes in chromatographic supplies and instrumentation. He has been an expert witness generally in the area of chemical analysis and basic chemistry primarily but not exclusively for cases involving patent litigation among pharmaceutical manufacturers.

Expert may consult nationally and internationally, and is also local to the following cities: Minneapolis, Minnesota - Saint Paul, Minnesota - Rochester, Minnesota - Burnsville, Minnesota - Saint Cloud, Minnesota - Eden Prairie, Minnesota - Minnetonka, Minnesota - Eau Claire, Wisconsin
