Tim Draelos has been at Sandia for over 32 years and received his Ph.D. at UNM in 1998, focusing on constructive neural networks. He has spent the last ten years conducting deep learning R&D, including work on seismic signal detection, phase identification, and event discrimination. He chaired special sessions on Machine Learning in Seismology at the 2016 and 2017 Seismological Society of America annual meetings and 2017 American Geophysical Union fall meeting. He has taught classes on machine and deep learning and was the founder and general chair of the 1st three Sandia Machine Learning and Deep Learning Workshops, starting in 2017. He has published papers in the Bulletin of the Seismological Society of America, Seismological Research Letters, and various machine learning conferences.
Tuan Ho is a Senior Member of the Technical Staff in the Geochemistry Department at Sandia National Laboratories. He earned his Bachelor of Engineering from Ho Chi Minh City University of Technology, Vietnam and his PhD from University College London, UK. His research interests include molecular interaction/properties in natural/engineering nanoporous materials related to subsurface applications: shale gas production, nuclear waste disposal, carbon dioxide capture and geological storage.
Dr. David J. Heldebrant is a Chief Scientist and Team Lead of the Separations Materials team under the Advanced Energy Systems Group in the Energy Processes and Materials Division at Pacific Northwest National Laboratory. Dr. Heldebrant joined PNNL as a post-doctoral research scientist in 2005.
Dr. Heldebrant's current research focuses on applying the principles of Green Chemistry to improve atom and energy efficiency and reduce toxicity of chemical processes and to make energy-related process more environmentally benign. Focus areas are on developing materials that can perform multiple tasks to reduce waste and improve energy efficiency in the fields of chemical separations and chemical conversions, applying these principles in areas of industrial gas separations, liquid/liquid separations and catalysis. The work focuses on the development of organic gas-separating liquids that can chemical remove CO2, SOx, and H2S from combustion, gasification or natural gas streams through applied and fundamental studies of gas absorption kinetics, thermodynamics and mechanistic studies.
