Sarat Vatsavayai, PhD

Specialist
Fields of Interest: 

Sarat Vatsavayai received a master of science degree in Human Genetics from Andhra University, India. He then did his doctoral work in the field of Huntington’s disease at the Open University, UK, where he was characterizing a novel mouse model and was trying to find out if DNA repeat instability could modify disease progression. In July 2013, he joined Dr. Seeley’s lab and is studying the molecular basis of C9orf72 mutation in frontotemporal dementia and amyotrophic lateral sclerosis.
