Specialty Division

Laboratory Medicine

Research Expertise

Development, validation and implementation of neurodegenerative diseases biomarkers in cerebrospinal fluid and plasma into treatment trials and clinical studies (eg, ADNI study; PPMI study). These studies include the use of manual and highly automated immunoassays and for amyloid beta(1-42) and for total tau the use of high sensitivity UPLC/tandem mass spectrometry. Multi-modal statistical analyses of these study data to address several questions including the diagnostic utilities of these biomarkers; assessments of the longitudinal trajectories of these biomarkers in AD, MCI and cognitively normal controls to assess the neuropathological changes over time in these individuals.

Clinical Expertise

Measurement and interpretation of the toxicokinetics of drugs and toxins in patients affected by them. Interpretation of the pharmacokinetics of immunosuppressant maintenance medications in transplant patients.

Other Expertise

Development and implementation of mass spectrometry-based methods for measuring small molecules of clinical utility including therapeutic drugs, toxins and special chemistry tests including 25-OH vitamin D.
