Research interests include Alzheimer's disease and related dementias, in particular how mutations in presenilin-1 cause familial Alzheimer's disease using transgenic mouse models. We also study the normal biological functions of the presenilin-1 gene using mouse models and cell culture.

Key words:
Alzheimer's disease
Presenilin-1
Familial Alzheimer's disease
Transgenic mice
