Dr. Sara Hernández Mejías. 

Sara obtained her BSc in Physics in 2011 from Basque Country University (UPV, Spain) and her MSc in biophysics in 2012 from the Madrid Autonomous University (UAM, Spain). She joined the group of Prof. Cortajarena to pursue her PhD in the development of nanostructured photo- and electro-active materials based on encoded protein self-assembly of engineered proteins. She finished the PhD in 2016. From 2016 to 2022, she performed her postdoctoral studies at international laboratories in the Netherlands, Sweden, and Spain, supported by fellowships like the Carl Tryggers Foundation research grant (Sweden) or Programa de Atracción de Talento (Spain). During her postdoctoral research she focused on studying photoinduced processes in synthetic photosystems using pump-probe spectroscopy. In 2022, she launched her independent career at IMDEA Nanoscience research institute (Spain), awarded with La Caixa Junior Leader grant, and established a bio-engineered nanophotonic research group.

Sebastián Mesa Apestegui

Sebastián obtained his BCs degree in Mechanical Engineering and then in Industrial Engineering, both from Universidad Carlos III de Madrid (Spain), spending a year as an Erasmus student at Tampere (Finland). He also made a research stay at Delft University of Technology (The  Netherlands), studying crack growth behavior under fatigue loads on 3D-printed titanium alloys. After,  he pursued a Master’s Degree in Advanced Materials, Nanotechnology and Photonics at Universidad Autónoma de Madrid (Spain). Upon graduation, he stayed at Laboratoire de Chimie de Coordination (LCC) of the CNRS (France) to work on the chemical synthesis of heterocyclic compounds to develop 2D materials. He joined the group in August 2023 to do his PhD studying photocatalytic properties of 2D materials in combination with photoactive proteins. He loves learning about science and nature. He enjoys walking in the countryside, watching plants and animals, reading, and playing sports.
