Brief Abstract:
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that is the most prevalent form of dementia among older adults. AD-related deaths have increased by 145% between 2000 and 2019 making it a looming public health challenge. My research focus is to develop computational methods, including novel image processing and graph theoretic tools for medical images for the accurate diagnosis of preclinical AD and for the identification of at-risk individuals for enrollment in clinical therapeutic trials for AD.
My research contributions include 1) the development of mathematical models for tau aggregation based on longitudinal tau measures from positron emission tomography (PET) and structural connectivity graphs from diffusion tensor imaging (DTI), 2) the identification of mechanisms of tau buildup in the aging brain to offer a macroscopic perspective on tau spread, 3) the prediction of tau buildup at future time-points with high accuracy from baseline data, and 4) the development of methods for the joint analysis of AD genotype and tau PET for relational inference and subtyping.
All interested students and faculty members are invited to attend the online defense via remote access.
