Vicky Kalogeiton
Vicky Kalogeiton is a professor at École Polytechnique and a researcher at LIX*, the Computer Science Laboratory of École Polytechnique. Within the VISTA team, she focuses on generative artificial intelligence. Her work particularly involves multimodal models—those that use images, text, sound, and more. These models are not solely based on large language models (LLMs) like ChatGPT. The key advantage is the ability to integrate context into analysis. Her research aims to develop generalizable, structured, and efficient methods applicable to various fields, including medical imaging.
Alejandro Alvarez Laguna
Alejandro Alvarez Laguna is a CNRS research scientist at the Plasma Physics Laboratory (LPP*). His field is the theoretical and numerical study of non-equilibrium plasmas. Under these conditions, ionized fluids—plasmas—exhibit complex interactions. A better understanding of these processes could, in particular, lead to improvements in plasma thrusters for satellites. In his ongoing project, HiMomPlas, funded by the ERC, Alvarez Laguna uses new methods in mathematics and statistical physics, validated by experimental data. Another goal of the project is to find alternatives to xenon, an expensive gas widely used in space propulsion.
Anna Korba
Anna Korba is a researcher at the Center for Research in Economics and Statistics (CREST*) and an assistant professor at ENSAE. Her research lies at the intersection of mathematics, statistics, and machine learning. In these fields, a major challenge is the efficient sampling of probability distributions. In most cases, only partial information about these distributions is available. The OptInfinite project, funded by the ERC, aims to build a unified framework to design and evaluate effective methods for complex distributions.
