Magnetic Confinement Fusion: integrated modeling techniques
This seminar is intended to lead listeners from the concept of magnetic confinement fusion to how plasma energy flows and is transported in the highest temperature zone within a tokamak fusion reactor, its core. To do this, the Magnetic Fusion Experiments Integrated Modelling group led by Pablo Rodriguez Fernandez, uses the combination of numerical computation algorithms together with machine learning techniques to accelerate predictions of plasma behavior in that area of the reactor.
In this work, Bayesian Optimization and Gaussian Processes techniques are explored to further reduce the computational cost of simulations, with a focus on surrogate model selection, hyperparameter optimization, data treatement and the search for a model that is able to tune to the changing nature of plasma energy transport.
Speaker: José Aguilera Toste is an Aerospace engineering and Aeronnautical master student in the School of Aeronautical and Space Engineers (ETSIAE) at the Technical University of Madrid (UPM), specializing in Space Vehicles. He is currently a UPM fellow and visiting student at Massachusetts Institute of Technology (MIT), researching machine learning techniques for the prediction of Plasma behavior in the core of a tokamak reactor.

Exploring Ultrasonography's role in ECMO: Detecting and Preventing Emboli Risks
Extracorporeal Membrane Oxygenation (ECMO) system is an artificial life support mechanism designed to aid individuals whose lungs or heart are not properly functioning in oxygenating their blood. This process continuously pumps blood out of the body and sends it through a series of devices that add oxygen and remove carbon dioxide, then returning oxygenated blood to the body. However, utilizing ECMO comes with certain risks, including the potential formation of emboli (both solid and gaseous) which, when entering the body, can lead to ischemia, stroke, or pulmonary embolism, among other complications. The detection and prevention of such emboli remain a major healthcare challenge.
We aim tackle this challenge leveraging ultrasonography, an imaging technique that employs sound waves to image organs, tissues, and other structures within the body, in a non-invasively way. In this talk, we will discuss how ultrasonography can be potentially used for detection of emboli within the context of ECMO.
