Clinical Interests

Dr. Dugger is overwhelmingly excited and honored to contribute fundamental knowledge that will aid in creating better biomarkers, therapies, and models of human diseases for all individuals. Throughout her career she has led, enabled, and enhanced many cross disciplinary projects, resulting in more than 60 peer-reviewed manuscripts and numerous private, state, and federally funded grants. Dr. Dugger has extensive expertise the neuropathology of Alzheimer's disease and related disorders, digital neuropathology, cross disciplinary dialog development and maintenance, clinicopathologic correlates, mentorship, advocacy, and administrative execution and oversight.

Research/Academic Interests

Dr. Dugger's research focuses on:

  1. understanding the heterogeneity within neurodegenerative diseases
  2. understanding the interaction of peripheral changes to aging and neurodegenerative diseases
  3. developing scalable workflows for deeper phenotyping of neurodegenerative diseases
