Dr. Angel Yanguas-Gil, Principal Materials Scientist, Argonne National Laboratory

With a background in theoretical physics, my current research activities focus on two areas: materials growth, and neuromorphic computing. In the area of materials, the focus of my research is understanding the fundamentals of materials growth, with a specific emphasis on the areas of advanced electronic materials and semiconductor processing. My research leverages the advanced computing, X-ray characterization, and the cutting-edge materials synthesis capabilities at Argonne to understand the synthesis of nanomaterials using chemistry-based techniques such as atomic layer deposition. Active areas of research include wide bandgap semiconductors for advanced power electronics, the development of in-situ capabilities to probe the structure of nanomaterials, and the development of state of the art, multiscale simulation tools to predict the scale up of thin film growth and the dynamics of infiltration for high aspect area materials. These are key issues for the fabrication of 3D architectures in semiconductor electronics, or for the integration of thin film technologies into energy storage applications. While my primary focus is on nanomaterials, recently we have applied a similar methodology to additive manufacturing. In the area of neuromorphic computing, my research focuses primarily on the exploration of novel architectures and algorithms to design smart systems and sensors inspired on the insect brain. My primary interest is on areas that go beyond the current state of the art in machine learning, such as the development of systems with the ability to adapt to changes in their environment in real time and capable of exhibiting task-dependent learning and processing. As part of our current activities in this field, I am currently leading a project from DARPA’s Lifelong Learning Machines program focused on the development of systems capable of dynamic learning. In addition to the exploration of novel architectures and algorithms, my research also focuses on understanding how to best translate these architectures into hardware, both through the exploration of existing neuromorphic chips, and through the development of design principles that will help guide the design of novel materials and devices. Potential applications include the development of more power-efficient, smarter sensors that could find applications in areas such as self-driving vehicles and drones, and internet of things related applications such as infrastructure monitoring or networked sensors.

As a proud UMSL physics alumnae and recipient of UMSL’s 2022 Distinguished Alumni Award, Dr. King was crucial to the development and signing of the Educational Partnership Agreement between NGA and UMSL, which aims to develop a variety of academic courses for careers in geodesy, geophysics, and geospatial intelligence. She formed the Geoscience and AI Application Lab through a Partner Intermediary Agreement with T-Rex (a St. Louis-based innovation and entrepreneur development center), where she is engaged in developing a collaborative, multi-disciplinary team of Government, Industry, and Academic Scientists who focus on the growth of budding research scientists working on NGA’s hardest mission-related problems. She believes the best science is born out of collaboration, diversity, and mentorship.

David McCollum, Senior R&D Staff

Dr. David L. McCollum is a Senior R&D Staff in the Mobility and Energy Transitions Analysis (META) Group at Oak Ridge National Laboratory, with expertise spanning economics, engineering, policy analysis, and corporate advisory services. His research attempts to inform state, national (developed and developing) and global energy and environmental issues on matters related to, among others, deep decarbonization, net-zero emissions pathways, energy-transport-climate policies, electric sector planning, end-use sector electrification (transport, buildings, industry), Sustainable Development Goals (including inter-dependencies), financing needs for the energy system transformation, and human dimensions of climate change. He employs energy-economic systems and integrated assessment models in support of this work (e.g., MESSAGEix-GLOBIOM, TIMES-MARKAL, REGEN, GCAM). Before joining ORNL in September 2021, David was a Senior Research Scholar with the Energy Program at the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria, and a Principal Technical Leader at the Electric Power Research Institute (EPRI) in Palo Alto, California. He currently holds secondary appointments as Guest Senior Research Scholar at IIASA; Research Fellow in Energy and Environment at the Howard H. Baker Jr. Center for Public Policy at the University of Tennessee; and Honorary Senior Research Fellow at Imperial College London. The latter is in his capacity with the Intergovernmental Panel on Climate Change (IPCC) Technical Support Unit (TSU - Working Group III) for the Sixth Assessment Report (AR6). David previously led activities within the Global Energy Assessment; IPCC Fifth Assessment Report (AR5 - WG III); IPCC Special Report on Global Warming of 1.5 °C; and other international, multi-stakeholder initiatives, such as for the World Bank and International Council for Science (ICSU). He is listed by Reuters as one of the world’s 250 most influential climate scientists. David received a PhD and MS in Transportation Technology & Policy from the University of California, Davis (USA), Institute of Transportation Studies; an MS in Agricultural & Resource Economics from the same institution; and a BS in Chemical Engineering from the University of Tennessee (USA).

David Alexander, Senior Science Advisor for Resilience, U.S. Department of Homeland Security

David J Alexander serves as the Senior Science Advisor for Resilience. He also leads the Enduring Sciences Branch of the Department of Homeland Security Science and Technology’s (DHS S&T) Technology Centers Division focusing on interdisciplinary research across the physical, biological, and life sciences to enhance knowledge, advance state of the art, inform investments and drive actions in national threats, hazards, and risks. Other programs he has spearheaded in DHS S&T include leading the S&T Flood Apex and Hurricane Technology Modernization programs as well as an analysis of Wildland Fire Operational Requirements and Capabilities in support of FEMA, US Fire Administration and other key stakeholders. Before his role in DHS S&T, Alexander served as the first appointed geospatial information officer for DHS and as Enterprise Geographic Information Systems Branch lead within the Federal Emergency Management Agency. Before coming to DHS, Alexander acquired practical experience across the local, state, federal, and private sectors. Alexander currently serves as a co-chair of the National Science and Technology Council’s Subcommittee on Resilience Science and Technology and is a member of the International Scientific Committee of the Eighth International Conference on Floodplain Management. He previously served as a member of the National Geospatial Advisory Council, DHS representative to the Federal Geographic Data Committee, co-champion for the National Spatial Data Infrastructure, chair of the Homeland Infrastructure Foundation Level Data Subcommittee. Alexander holds a Doctor of Philosophy from George Mason University and is also an adjunct faculty member at Delta State University.
