About

Alissa J. Nelson is a proteomics researcher whose work centers on developing and refining high-throughput methodologies for studying post-translational modifications (PTMs), particularly ubiquitylation and phosphorylation. Her most recognized contribution is the automation of UbiFast, a sensitive and highly multiplexed platform for ubiquitin enrichment and site-specific identification of ubiquitylation sites. This work, which has accumulated 23 citations since its 2021 publication, addresses a critical bottleneck in the field by enabling deep-scale enrichment of K-ε-GG peptides at greater speed and reproducibility than previously possible, advancing our understanding of ubiquitylation's diverse cellular roles. Nelson has also made notable strides in phosphoproteomics standardization, co-developing a multipathway phosphopeptide standard comprising 131 heavy-labeled phosphopeptides that serves as a quantitative "yardstick" for cross-laboratory data harmonization. Published in 2023 and already accruing 8 citations, this work demonstrates that reporting data as ratios to a common standard dramatically improves inter-lab consistency. Collectively, Nelson's research is shaping best practices in quantitative proteomics, making complex PTM profiling more accessible, reproducible, and scalable for the broader research community.
