    Researchers Study Effects of Climate Change on Forests With Help From Space

    August 07, 2019

    Linnea Saby, a Ph.D. student in the Department of Engineering Systems and Environment and Presidential Fellow at the Data Science Institute, is working on a cutting-edge project to study the effects of climate change on Shenandoah National Park forests. Linnea and her research partner, environmental science Ph.D. student Jake Malcomb, will use massive geospatial data sets collected from the International Space Station through two new NASA programs.

    Their work aims to help understand how to manage and conserve forests under changing climate conditions. The researchers told UVA Today they will use conventional and new data science techniques and tools, including artificial neural networks, to analyze the huge amounts of data. Artificial neural networks are a form of artificial intelligence built with algorithms based on the structure of the human brain that can detect patterns and trends in data.

    Linnea’s Engineering Systems and Environment advisors are Associate Professor Jonathan Goodall and Ernest H. Ern Professor of Environmental Science Larry Band. She is a research assistant in the Link Lab, UVA’s Engineering’s multidisciplinary center for cyber-physical research.

    August 01, 2019

    Professor James H. Lambert, who directs Engineering Systems and Environment’s Center for Risk Management of Engineering Systems, chaired the 2019 Fifth World Congress on Risk. The Congress is organized by the Society for Risk Analysis in partnership with the Society of Environmental Toxicology and Chemistry Africa Biennial Conference to grow innovation and knowledge across risk analysis and management communities. It brought together government, industry and academic scientists and experts from a variety of disciplines to exchange ideas and research related to this year’s theme, “Development and Resilience.”

    As hosts, the partnering organizations continue a tradition of providing global leadership in risk analysis and management science and policy. Participants in the Congress exchanged academic research, innovations, and practical knowledge and experience to expand the frontiers of risk analysis. Combining their interdisciplinary expertise, the participants aim to leverage their insights and grow capabilities to address world societal challenges involving health, safety, environment, engineering and infrastructure, enterprise, emerging technologies, regulation, communication, security, policy and finance. Read more about the program here.

    UVA’s Center for Risk Management of Engineering Systems was represented at the Fifth World Congress on Risk in by Professors James H. Lambert, Marwan Alsultan, and Ayedh Almutairi and Alexander Ganin, Zachary Collier and Heimir Thorisson.

    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.

    Hyunglok 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.” Hyunglok 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.

    Systems Engineering Student Makes Case at Harvard Law School for Electronic Research Assistant

    June 28, 2019

    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.
