Welcome! You’ve reached my homepage, where you can learn about my research and software tools. I’m currently a Postdoctoral Scholar at the USC Laboratory of Neuro Imaging advised by Arthur W. Toga. Previously, I received a PhD in Computer Science from Brown University advised by David H. Laidlaw.

My research focuses on development and evaluation of computational tools for neuroimaging and neuroinformatics. I’m presently working on computational approaches for characterizing brain connectivity and microstructure using diffusion magnetic resonance imaging (MRI). Through interdisciplinary collaborations, we are applying these techniques to map normative changes throughout development and aging, as well as disruptions associated with dementia, environmental exposure, traumatic brain injury, and stroke.

You can learn more about this work in the publications listed below. Much of it uses software I developed called the Quantitative Imaging Toolkit (QIT), which you can learn about by visiting the website.
