    Hyunglok Kim, a second-year Ph.D. student in the Department of Engineering Systems and Environment, has been selected for NASA’s first class of Future Investigators in NASA Earth and Space Science and Technology. His research proposal was one of only 59 accepted for the new Future Investigators program in the earth science funding division. The maximum award is $135,000 over three years.

    Kim is working with Professor Venkat Lakshmi, who joined the Engineering Systems and Environment faculty in 2019, as his principal investigator. The project is “Diurnal Soil Moisture Using Satellite Observations and Data Assimilation.” Kim said he wanted to investigate the topic because he believes it offers critical — and surprising — insight to improving our knowledge of Earth’s climate systems.

    NASA peer-reviewed 428 earth science proposals and a total of 966 proposals that were submitted in response to the inaugural Future Investigators in NASA Earth and Space Science and Technology solicitation, according to the website. Four funding divisions in the Science Mission Directorate at NASA Headquarters — earth science, heliophysics, planetary science and astrophysics — provided oversight for the peer review process.

    The solicitation invited proposals for graduate student-designed research projects that contribute to the Science Mission Directorate’s science, technology and exploration goals.

    Faraz_250.jpg

    Faraz Dadgostari, who is working on his Ph.D. in systems engineering at the University of Virginia, gave a talk at Harvard Law School titled “Learning Knowledge Search Techniques in the Law.” The project is a collaboration with Michael Livermore, a UVA Law professor and Peter Beling, professor and associate chair for research in the Department of Engineering Systems and Environment at UVA.

    Their work combines natural language processing and reinforcement learning to replicate how attorneys search and select from legal cases when they are developing arguments for given legal questions. The team’s approach learns from the in-text citations in U.S. Supreme Court opinions, leading to algorithms that search for the smallest set of relevant cases required for the legal arguments the lawyer is trying to make, Faraz said.

    The work introduces a novel theory of legal search and new reinforcement learning formulations. The project is supported in part by the Center for Visual and Decision Informatics, a National Science Foundation Industry/University Cooperative Research Center. Professor Beling is the center’s UVA site director.
