Background and activities

I am currently working as a postdoc in a project on modelling of battery production systems at the Industrial Ecology (Indecol) department with Anders H. Strømman and Odne S. Burnheim as supervisors, where we work on identifying potentially attractive manufacturing technologies that can help the rapidly expanding battery production industry.

My background consists of a bachelor in Chemistry and master in Nanoscience and Nanotechnology by the University of Barcelona (UB). In my master thesis I worked in the synthesis and characterization of carbon nanotubes for supercapacitor applications. Afterwards I worked in the Catalan Institute of Advanced Chemistry (ICQA) on analysis of surfactant properties. Afterwards I did an internship at the Chemistry department of NTNU where I worked in a project aiming at the development of catalyst layers for hydrogen fuel cells. Thereafter I worked in the field of process engineering in Sintef Energy focusing in heat recovery and power cycles thermodynamic modelling as well as process design for CO2 capture. 
Later I obtained a PhD degree on the field of material science at the Materials Technology Department (IMA) at NTNU. The project aimed at investigating the formation of fouling layers known as "Hard Grey Scale" (HGS) that form in aluminium production off-gas systems and require costly periodic cleaning procedures. The work involved the design and construction of a fouling probe known as cold-finger, which was used in industrial experiments to investigate the growth and properties of HGS and multiphase computational fluid dynamics (CFD) modelling to investigate HGS formation mechanisms.

Thereafter, I worked in the EU project RELIEVE related to the recycling of lithium ion batteries from electrical vehicles, focusing on the thermodynamic and kinetic modelling of the leaching process to recover the valuable metals from batteries before joining Indecol.
