## Abstract

ABSTRACT
 The current medical landscape is not equipped to handle Alzheimer’s Disease, with the projected
afflicted population tripling between 2010 and 2050 and care costing the U.S. hundreds of billions of dollars
each year. To better understand and diagnose the disease, attention has shifted towards biomarkers. The
oligomeric forms of amyloid beta—which can be stabilized by metal ions—have been labeled one of the most
destructive driving forces behind Alzheimer’s Disease. Mass spectrometry is a prominent force in the disease
characterization, but due to the prominent noncovalent landscape of amyloid beta proteoforms, mass
spectrometry must be applied in a way that preserves endogenous molecular context for maximal effect.
 Native top-down mass spectrometry improves on the information accessible from standard approaches
by preserving inter- and intramolecular, noncovalent interactions. However, the approach is inaccessible in
high throughput due to the required manual nature of data acquisition for large analytes. Another barrier to the
characterization of noncovalent protein assemblies via mass spectrometry is the lack of software for the
localization of labile modifications (e.g., metals). The proposed work will address the first obstacle through
software that autonomously reconfigures the mass spectrometer to enhance each analyte’s transmission for
characterization. The optimizations can happen in real time with the actual analyte during steady spray or in
reference to a calibrant for high-throughput implementation. Neural networks built on previously collected data
will allow for continual and lightweight model improvement. The second obstacle mentioned will be addressed
through software that quantitatively identifies and places labile modifications in 1D and 3D space. The dual-
software platform will enable rigorous screening and quantitation on amyloid beta and its oligomers, leading to
data-driven conclusions on the spatiotemporal progression of Alzheimer’s Disease.
 Training will first take place via an internship at Thermo Fisher Scientific. While manipulating instrument
hardware and software to enhance high-range signal transmission, the applicant will become proficient in
instrument code and use. Then, the applicant will learn how to conduct top-down proteomics workflows at the
Proteomics Center of Excellence while becoming proficient in bioinformatics software via Protinaceous. Each
center is populated with high-impact scientists that engage in industry, which will prompt generalizable design.
 The proposed works align directly with the NIA’s mission in both their short-term and long-term
implications. A platform will enable high-throughput, rigorous, and unprecedented characterization of amyloid
beta and its oligomers within their native structural contexts. Furthermore, the created platform will be readily
applicable to any other disease or biological system, tangential to the original research or not. The conclusions
asserted usi...
