Lori Diachin is the Deputy Director for the U.S. Department of Energy’s Exascale Computing Project (ECP). ECP is a collaborative Department of Energy effort supported by both the National Nuclear Security Administration and the Office of Science to accelerate the delivery of a capable exascale computing ecosystem for breakthroughs in scientific discovery, energy assurance, economic competitiveness, and national security (https://www.exascaleproject.org/). In her role as the Deputy Director, Lori assists the Project Director in setting the strategic direction for ECP and ensuring that the project has an impactful and executable plan that delivers on its goals and objectives.

Lori is also serving as the Deputy Associate Director (DAD) for Science and Technology in the Computation Directorate at Lawrence Livermore National Laboratory. The Computation Directorate has approximately 1000 staff serving the needs of the laboratory in areas ranging from high performance computing, computing sciences for the missions of LLNL, and information technology for business and workforce enablement. As Computation DAD for S&T, Lori serves as a senior-level advisor to the Computation Associate Director and to division leaders and institute directors on strategies to develop and sustain critical computer and computational capabilities.

She previously served as the program director for the HPC4Manufacturing and HPC4Materials programs in the DOE EERE and FE program offices. She was involved with DOE’s SciDAC program from 2001-2018, most recently serving as the FASTMath Institute Director; leading a team of over 50 researchers from 10 different organizations. She was the the Director for the Center for Applied Scientific Computing (CASC) for 6 years and the Acting Information Technology Department head at LLNL for two years. CASC houses approximately 125 applied mathematicians, computer scientists, and data scientists who conduct world class, collaborative scientific research and development on problems critical to national security. The Center’s core competencies include high performance computing, computational physics, numerical mathematics, computer science, and data science.

Lori Diachin has over 25 years experience in applied mathematics research where her areas of expertise include mesh quality improvement, mesh component software, numerical methods, and parallel computing. She is the co-author of over 50 technical journal articles, book chapters, and conference proceeding articles in these areas. Before joining LLNL, Lori was a computer scientist at Argonne National Laboratory and a Member of the Technical Staff at Sandia National Laboratory. Lori received her Bachelor's degree in Mathematics from Edinboro University of Pennsylvania in 1988 and her Ph.D. in Applied Mathematics from University of Virginia in 1992. She joined Lawrence Livermore National Laboratory in 2003.
