Overview of Dr. habil. Alexander Litvinenko's visit from RWTH to the StochNum group

About

Dr. habil. Alexander Litvinenko visited the StochNum group at KAUST from February 5 to 22 as part of his ongoing collaboration with the Stochastic Numerics group and Principal Investigator Raul Tempone. During this visit, he also initiated a new collaboration with PhD student Maksim Chupin, focusing on low-rank tensor methods in stochastic optimal control.

In addition, Dr. Litvinenko continued his collaboration with the group of Professor Rolf Krause. Building on previous joint work with research scientist Dmitry Logashenko in the field of uncertainty quantification for density-driven flow, the team prepared a new manuscript addressing uncertainty quantification and inverse problems in this area.

Beyond his research activities, Dr. Litvinenko reconnected with former colleagues, including David Keyes, Havard Rue, Marc Genton, and Ricardo Lima, to exchange insights, discuss current research trends, and explore potential future collaborations.

During his stay, he further developed his expertise in stochastic optimal control and made significant progress on inverse problems in density-driven flow. He was also invited to deliver a talk to the High-Performance Statistical Computing Community.
