FOOD TOXICOLOGY. Expert has conducted research on a wide variety of foodborne toxicants, both naturally-occurring and additives. Special interests have included food allergies and allergens, sulfites, histamine poisoning, and processing-induced toxicants. He is widely viewed as an expert on naturally-occurring toxicants in foods. He has been an expert witness in cases involving sulfites, allergies, histamine and scombroid fish poisoning, E coli 0157:H7, and wine adulterants.

FOOD ALLERGIES/SENSITIVITIES. The primary thrust of Expert's research has been the identification and characterization of allergenic food proteins. He has studied the effects of processing on food allergens and methods for the detection of food allergens. He is knowledgeable of other types of food sensitivities and has done considerable research on sulfite-induced asthma.

FOOD SAFETY. Expert's interests and expertise are primarily in the area of the chemical hazards in foods. He is generally familiar with the microbiological hazards also with special expertise on histamine-producing bacteria associated with scombroid fish poisoning. He is knowledgeable of the interactions between foodborne toxicants and nutrients.

FOOD POISONING. Expert has considerable expertise regarding specific types of food poisoning: food allergies and sensitivities and scombroid fish (histamine) poisoning. He is knowledgeable of other types of food poisoning and the methods used to investigate suspected food poisoning cases.

IMMUNOCHEMICAL ASSAY. He has developed immunoassays for the detection of trace residues of one food in another food. These assays are useful in the evaluation of food allergens.

ANTIBODY PRODUCTION. The production of polyclonal antisera to food proteins and food extracts has been a prevalent part of Expert's research efforts. Specific foods have included peanut, soybeans, almonds, Brazil nuts, whey, casein, milk, crustacean shellfish, fish, walnuts, pecans, cashews, pistachios, and eggs.

FOOD TECHNOLOGY/SCIENCE/ENGINEERING. As a faculty member at the University of Nebraska, Expert has access to state-of-the-art pilot plants and laboratories which can be used for proprietary food product and process development, improvement, or evaluation.

FOOD INGREDIENTS & ADDITIVES. As past Chair of the Food Chemicals Codex Committee of the National Academy of Sciences, Expert is one of the foremost experts on food ingredients and additives. He has conducted research on sulfites, antimicrobials, MSG, and hydrolyzed proteins. His expertise primarily is oriented toward safety and purity of food ingredients and additives.

PROTEINS & PROTEIN PRODUCTS. Expert is an expert on the allergenicity and toxicology of food proteins and protein products. He is familiar with the processing and applications of these materials.

FOOD SPOILAGE; FOOD SPOILAGE DETECTION. Expert is familiar with the area of food spoilage and especially with the detection of spoiled foods. He has conducted shelf-life determination and studied both microbial and oxidative spoilage. He has also studied the use of chemicals as indicators of bacterial decomposition. Novel approaches, beyond those currently commercial

He has served on several legal cases as an expert witness involving the presence of unsuspected allergenic foods in other foods leading to alleged consumer illness.He has served on several legal cases as an expert witness involving alleged adverse reactions to ingestion of sulfite food additives.He has served on several legal cases as an expert witness where the plaintiffs alleged that they had contracted scombroid fish poisoning (histamine poisoning) from ingestion of spoiled fish.He has conducted allergen audits of food processing facilities.He has prepared expert opinions and conducted quantitative risk assessments for the food industry relating to the risks associated with residues of allergenic foods that might contaminate other foods.

Expert may consult nationally and internationally, and is also local to the following cities: Omaha, Nebraska - Lincoln, Nebraska - Council Bluffs, Iowa
