Rubén Casas Jaraíces is graduated in Chemistry by the University of Jaén (2012). After graduating, he decided to continue his training at Poznan University of Technology (Poznan, Poland) where he did a Master’s degree in composites and nanomaterials. His Master’s degree final project was focused on the use of new ionic liquids for the liquid-liquid extraction of zinc from aqueous solutions resulting from the galvanising process.
In 2017, he started to work with the Theoretical and Experimental Physical Chemistry Research Group (FQM173) from University of Jaén. Throughout this period he accomplished his Master’s degree in Advances in Food Safety and he based his Master’s degree final project on the presence of pesticide residues in the food industry.

From 2020 to 2022 he worked as technical support staff at the Scientific-Technical Instrumentation Center (CICT) at the University of Jaén. During this period of time as a technician on the analysis and structural determination area, he specialized on a number of new analysis techniques such as CHNS Elemental Analysis, Micro X-ray Fluorescence Spectrometry (Micro-XRF), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Gas Chromatography (GC) and Liquid Chromatography (HPLC). He then worked in 2023 at the University Research Institute for Iberian Archaeology (IUIAI-UJA) at the University of Jaén.This role involved developing and implementing new methods to study archaeological sediments by using new chromatography techniques (GC y HPLC) and Spectroscopic techniques (Micro-XRF).

In September 2024, he joined the CIC energiGUNE team as a laboratory technician for the General Analysis Characterization Unit.
