Amyloidosis from a Physical Biochemistry Perspective
Abstract
Amyloidosis is the name given to a family of debilitating diseases which are all associated with the deposition of linear protein aggregates, known as amyloid fibers, into various tissues and organs within the body. Important examples of the amyloidosis disease spectrum include Alzheimer’s disease and Type 2 diabetes. Other well-known examples of infectious amyloidosis include the infectious spongiform encephalopathies, Kuru and Mad Cow’s disease. Here I describe results gathered from a range of physical measurements and computer simulations which I believe provides a very powerful synthesizing capability for considering the amyloidosis diseases through a single mechanistic paradigm.

Research Fields and Interests:
I study disease and disease associated chemistry through the lens of physical chemistry – a field I call physical biochemistry. I use a range of physical techniques including mathematical modelling and wet experimental biochemistry to study three main topics,
(i.) Amyloid formation and its relationship to disease.
(ii.) Adsorption of virus to the epithelial cell membrane.
(iii.) Cell signaling via diffusion in the cell cytosol and membrane.
