Research

Description of Research Expertise:

RESEARCH INTERESTS
Neurodegenerative diseases caused by filamentous aggregates of A-beta, tau and alpha-synuclein as well as in vitro and animal models of these diseases.

RESEARCH TECHNIQUES
Morphological, genetic, molecular biological and biochemical methods are used to study samples from patients with neurodegenerative diseases as well as those from model systems.

RESEARCH SUMMARY
Research currently centers on molecular mechanisms of neuron dysfunction, degeneration and death in normal aging and in neurodegenerative diseases (Alzheimer's and Parkinson's disease, frontotemporal dementias with/without parkinsonism, motor neuron disease, etc.). This research uses immunological, biochemical, genetic, molecular and morphological methods to study human CNS and PNS tissue samples (postmortem or surgical), cell lines, synthetic proteins, and transgenic models of neurodegenerative diseases.
