I spent four weeks in Bioinicia in two periods between the summer and Christmas 2019. In addition to performing technical activities and experiments, I had many meetings (and bears) with my friend Chema Lagaron and his crew. We take advantage of theses meetings to analyse the impact of the secondments in the career and formation of our secondees, trying to understand how we can improve their scientific and technical skills. We also discussed new opportunities for collaboration in future projects. It was noticeably some fruitful brainstormings regarding applications of electrospinning.
