Leen Alawieh

Leen Alawieh, CRD

As a new postdoctoral fellow in Berkeley Lab’s Center for Computational Sciences and Engineering (CSEE), Leen Alawieh will be integrating experimental observations with numerical simulations and mathematical formulations to quantify uncertainties in models of complex physical systems.

“There has been a general consensus among researchers to shift from the strict deterministic to the probabilistic interpretation of physical model predictions,” says Alawieh. “This is instigated by the multitude of uncertainties that taint physical systems both in experiments and models. Accounting for these uncertainties can sometimes lead to widely different model predictions, which could have serious impacts on scientific insights, designs and decisions that rely on these predictions.” 

Although her work on uncertainty quantification methods in CSEE will focus primarily on combustion applications, she notes that it will also be applicable to other research areas like climate and earthquake forecasts, carbon sequestration, as well as material design and optimization.

Originally from Lebanon, Alawieh completed her undergraduate studies in Chemistry at the American University of Beirut in Lebanon. Shortly after, she came to the United States as a Fulbright Scholar and pursued a Master’s degree in Physical Chemistry and Physics from the University of Texas, Austin (UT Austin). She earned her PhD in Mechanical Engineering from Johns Hopkins University. And before coming to Berkeley Lab, Alawieh developed algorithms for extreme-scale Bayesian inverse problems and the stochastic representation of model inadequacy as a postdoc at UT Austin’s Institute for Computational Engineering and Sciences.

In her free time, she enjoys doing indoor and outdoor sports activities, attending live music concerts and theater performances, as well as reading.

About Computing Sciences at Berkeley Lab

The Computing Sciences Area at Lawrence Berkeley National Laboratory provides the computing and networking resources and expertise critical to advancing Department of Energy Office of Science research missions: developing new energy sources, improving energy efficiency, developing new materials, and increasing our understanding of ourselves, our world, and our universe.

Founded in 1931 on the belief that the biggest scientific challenges are best addressed by teams, Lawrence Berkeley National Laboratory and its scientists have been recognized with 13 Nobel Prizes. Today, Berkeley Lab researchers develop sustainable energy and environmental solutions, create useful new materials, advance the frontiers of computing, and probe the mysteries of life, matter, and the universe. Scientists from around the world rely on the Lab’s facilities for their own discovery science. Berkeley Lab is a multiprogram national laboratory, managed by the University of California for the U.S. Department of Energy’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit energy.gov/science.
