Postdoctoral Fellowship in CFD Modelling and Simulation
Deadline: January 22nd 2020

Mesoscopic Fluid Dynamics Modelling and Simulation of Espresso Coffee Extraction
Applications are invited for a postdoctoral position in mesoscopic modelling of espresso coffee extraction at the CFD group (BCAM) in collaboration with the Illycaffè. The percolation of hot water through ground coffee represents a complex thermo-fluid dynamics process where particulates and aromatics migrate from the grains into the brew. From a coffee cup quality point of view it is necessary to model accurately the mass transfer occurring during the process, focusing on the solubilization of key odorant and taste-wise compounds from the roasted coffee phase. In fact, distinct compound kinetics generally lead to an altered balance in the final cup depending on extraction times, ground coffee granulometry, applied pressures and temperatures resulting, finally, in a highly variable sensorial experience. The goal of this project is to use and further develop an existing simulation framework (based on Smoothed Particle Hydrodynamics and Dissipative Particle Dynamics techniques) to control and engineer coffee flavors by 'virtually' monitoring the balance of specific key-odorant or taste-actives compounds in the beverage under unexplored flow processing conditions. The postdoctoral candidate will work under the supervision of Ikerbasque Prof. Marco Ellero (CFD group, BCAM) on the developments and use of mesoscopic particle-simulation methods to better understand the mesoscopic extraction kinetics. He/she will also interact closely, both with the Illycaffè R&D Department in Trieste, Italy (Dr. Luciano Navarini), and with experimental groups at the College of Engineering (Swansea University UK) where X-ray micro-CT techniques will be used to morphologically characterize the ground coffee microstructure.

Postdoctoral Fellowship in Geometric Modeling and Manufacturing
Deadline: January 22nd 2020

Geometric Modeling and Manufacturing
The researcher will work on a research project in the framework of ADAM^2: Analysis, Design and Manufacturing, using Microstructures, funded by FET Open Project #862025. Possible research topics include, but are not limited to: simulations of 5-axis hybrid manufacturing, in particular 3D printing and 5-axis computer numerically controlled (CNC) machining, free-form surface rationalization, and tool-shape design and optimization. Previous experience in geometric modeling projects is particularly welcome.

Postdoctoral Fellowship in Applied Analysis

Postdoctoral Fellowship in Applied Analysis
Deadline: January 22nd 2020

Harmonic and Fourier Analysis, and applications to Partial Differential Equations. The current postdoc position is aimed to work on topics within the framework of Harmonic Analysis and its application to PDEs. In this concern, the potential problems will be related, in a broad sense, with the study of properties of singular integrals and other objects in connection with solutions to elliptic and parabolic equations. More specifically, the postdoctoral candidate will work under the supervision of Ikerbasque Research Professor Carlos Pérez and Ikerbasque Research Fellow and Ramón y Cajal Luz Roncal on several projects related to:

Sharpness of classical inequalities in Euclidean and non-Euclidean settings involving operators of local and nonlocal nature.
Singular integrals and weighted inequalities
Elliptic and parabolic equations
Analysis of operators via the semigroup theory and orthonormal expansions
Unique continuation principles of continuous and discrete type
Harmonic measure and rectifiability
