Our mission at the Data Science Institute (DSI) is to enable excellence in data science research and applications across the Laboratory's core missions.

Data science has become an essential discipline paving the path of LLNL's key program areas, and the Laboratory is home to some of the largest, most unique, and most interesting data and supercomputers in the world. The DSI acts as the central hub for all data science activity—in areas of artificial intelligence, big-data analytics, computer vision, machine learning, predictive modeling, statistical inference, uncertainty quantification, and more—at LLNL working to help lead, build, and strengthen the data science workforce, research, and outreach to advance the state-of-the-art of our nation's data science capabilities.

Data Scientist Spotlight

Marisol Gamboa

Marisol Gamboa

Computer Scientist

Marisol Gamboa thrives at the intersection of solving challenges in unique ways and mentoring the next generation. Over her 18-year career at LLNL, she has honed expertise in software engineering, web applications, and big data analytics by developing solutions for numerous defense and counterproliferation programs—such as tools that help Department of Defense personnel distill, combine, relate, manipulate, and access massive amounts of data in a timely manner. “The many lessons I’ve learned over the years have positioned me to tackle any challenge knowing that I am able to learn quickly and adjust to any situation in real-time,” she says. Gamboa is the Deputy Division Leader for LLNL’s Global Security Computing Applications Division as well as Computing’s Workforce Team Lead. She formerly co-directed the Data Science Summer Institute and created the annual Data Science Challenge with UC Merced. Active in outreach to young women and underrepresented minorities in STEM—including LLNL’s Women in Data Science regional events—Gamboa holds a B.S. in Computer Science from the University of New Mexico.

New Research in AI

A team of LLNL computer scientists has three papers accepted to the 2021 AAAI Conference on Artificial Intelligence, a premier event in AI research. Co-authors from Arizona State University interned at the Lab during summer 2020. Preprints are available:

Three plots showing noise ratio of test accuracy with model F in red and model M in blue; model F outperforms model M
Figure 2(a) from the third paper shows the behavior of the Uncertainty Matching Graph Neural Network (UM-GNN) model for the Citeseer graph-structured dataset under varying types and levels of poisoning attacks. The second model F (red line) has learned from, and improved upon, the first model M (blue line).
