Timothy Kneafsey P.E., Ph.D. is a Geological Scientist, Mechanical Engineer in the Energy Geosciences Division at Lawrence Berkeley National Laboratory (Berkeley Lab) and the Head of the Hydrocarbon Resources Program. He performs laboratory and field experimental studies on a variety of topics including heat transfer and mass transport in fractured and porous rock; measures hydrological, geophysical, and geomechanical properties of hydrate-bearing sediments and supercritical CO2-bearing rock; probes transport of acid gases in geothermal systems; visualizes fluids (liquid and gas) flow through coal and rock while simultaneously measuring geophysical properties related to coal-bed methane and CO2 sequestration; and investigates issues related to CO2 sequestration including CO2-induced density driven brine advection. Dr. Kneafsey has used a variety of visualization tools in his investigations including direct and differential imaging, spatially resolved infrared thermometry, and x-ray CT scanning, and has a patent for a CT scanner design. Dr. Kneafsey holds Bachelor of Science degrees in Mechanical and Civil Engineering from the University of New Mexico, a Masters of Science degree in Civil Engineering from the University of California at Berkeley, and a Doctorate in Civil and Environmental Engineering, also from the University of California at Berkeley. He is a registered Civil Engineer in California.
Bert de Jong leads the Computational Chemistry, Materials, and Climate Group, which advances scientific computing by developing and enhancing applications in key disciplines, as well as developing tools and libraries for addressing general problems in computational science.
de Jong is the director of the LBNL Quantum Algorithms Team QAT4Chem, the team director of the Accelerated Research for Quantum Computing (ARQC) Team AIDE-QC, both funded by DOE ASCR, focused on developing software stacks, algorithms, and computer science and applied mathematics solutions for chemical sciences and other fields on near-term quantum computing devices. He is also a co-PI on the ARQC team FAR-QC (led out of Sandia). He is also part of LBNL’s quantum testbed, developing superconducting qubits. He is the LBNL lead for the Basic Energy Sciences Quantum Information Sciences project (led out of PNNL), where he is focusing on new approaches for encoding wave functions and embedding quantum systems. In addition, he is a co-PI on an LBNL led HEP funded quantum information science projects.
de Jong is a co-PI within the DOE ASCR Exascale Computing Project (ECP) as the LBNL lead for the NWChemEx effort, contributing to the development of an exascale computational chemistry code. He is the LBNL lead for the Basic Energy Sciences SPEC Computational Chemistry Center (led out of PNNL), where he is working on reduced scaling MCSCF and beyond GW approaches for molecules.
He leads an LBNL funded effort on machine learning for chemical sciences, focused on developing deep learning networks (GANs and autoencoders) for the prediction of structure-function relationships and its inverse, with a demonstrating in mass spectrometry. As part of this effort, his team developed the ML4Chem Python package.
Areas of expertise: software and algorithms for near-term quantum computing devices, machine learning, supercomputing, computational chemistry.
Emilio received his B.S. in Electrical Engineering and Physics from Missouri University of Science and Technology in 2007. After graduating he worked for the NASA Marshall Space Flight Center developing non-destructive evaluation techniques for applications related to the US space program. He completed his PhD in Electrical Engineering from the Massachusetts Institute of Technology in 2013 where he worked on high-frequency high-power THz sources and the development of Nuclear Magnetic Resonance spectrometers using Dynamic Nuclear Polarization. His thesis was on the first photonic-band-gap gyrotron travelling wave amplifier which demonstrated record power and gain levels in the THz frequency band.
He completed his postdoc at MIT with a joint appointment in the Nuclear Reactor Lab and the Research Laboratory for Electronics at MIT where he demonstrated the first acceleration of electrons with optically generated THz pulses. He joined the Technology Innovation Directorate at SLAC in August of 2015 where he continues his work on high power, high-frequency vacuum electron devices; optical THz amplifiers; electron-beam dynamics; and advanced accelerator concepts. His recent interests include ultrafast characterization; defect formation in semiconductors; and superconducting and solid-state devices for quantum information.”
