August 2017

Shilpy's paper "Mitochondrial Dysfunction in the APP/PSEN1 mouse model of Alzheimer's disease and a novel protective role for ascorbate" was accepted to Free Radical Biology and Medicine.

July 2017

The lab welcomed 16 High School students from the Vanderbilt Talented Youth Program into the lab to learn some basics about Alzheimer's disease research, and to practise their genotyping, brain dissection, tissue slicing and behavioral coding skills. We look forward to seeing some of these students back as undergraduates and graduate students in due course!
