First highlighted in The Scientist in 2012, Rommie Amaro earned a Presidential Early Career Award before diving into groundbreaking computational work. Her laboratory develops detailed simulations of disease‑relevant proteins—ranging from cancer therapeutics to influenza viruses—and forges collaborations with experimental groups to accelerate translation. “Partnering with experimentalists is what propels these projects forward,” Amaro remarked.
Receptor Proteins Jiggle Differently on a Crowded Dancefloor
Rather than isolated crystal lattices, Amaro builds extensive three‑dimensional, in‑situ simulations that place proteins within complex cellular contexts. By enlarging her computations to encompass whole viral envelopes, she examines how inherent atomic forces behave amidst dense environments. “My aim was to model a protein inside its entirety rather than view it in isolation,” she explained.

COVID‑19, Massive Data, and Going Further with AI
When the pandemic erupted, Amaro turned her talent to SARS‑CoV‑2, leveraging her specialized modeling pipeline to elucidate the spike protein’s entry mechanisms. Her team demonstrated that the typical glycolipid coat extends far beyond being a passive shield—it actively participates in the infection cascade, challenging prevailing notions about glycan functions.
Creating such petabyte‑scale simulations has generated unprecedented data sets. Managing these voluminous libraries requires a fundamental shift from traditional analysis methods to modern, AI‑enhanced workflows, marking a transformative era for computational biology.
Amaro comments on the growing accessibility of artificial intelligence, noting that tasks once demanding months of manual computation now yield results in days. This acceleration prompts scholars to reassess their roles, emphasizing the importance of strategic collaboration and intelligent leverage of advanced tools to push discovery boundaries further than previously imagined.
