Description of Research ExpertiseThe Axelsen laboratory is focused on the pathogenesis of Alzheimer's disease, particularly in the roles of oxidative stress and protein lipid interactions. A variety of whole-animal models and in vitro systems are used, as well as a large repository of human brain samples. The laboratory has developed novel isotope-based techniques for characterizing oxidative stress in brain using mass spectrometry and various forms of optical spectroscopy, including infrared, fluorescence, and internal reflection spectroscopy.
Description of Clinical ExpertiseClinical pharmacology, Drug therapy, Adverse drug reactions, Drug-drug interactions; Infectious Diseases, especially emerging antimicrobial resistance; HIV/AIDS, Travel and International Medicine
