Dr. Johnson's research focuses on the application of mass spectrometry and protein chemistry techniques to the study of food allergens and allergy. Although the primary focus of the Johnson lab is detection of allergens in foods, he also maintains an interest in the characterization of food allergens for use in clinical environments. Research objectives include :
• Development of MS methodology for the detection and quantification of food allergens
• Application of untargeted screening MS approaches to food safety, especially allergens.
• Identification of novel food allergens by novel MS-based approaches.
• Characterization of allergen preparations for clinical use.
