My main research interest concerns the evolution of chloroplasts, and I am particularly interested in the evolution of the two protein complexes â€œTranslocons at the Outer and Inner Chloroplast envelope membranesâ€ (TOC and TIC respectively). These protein complexes transport nuclear-encoded proteins into the chloroplast, and the evolution of TOC/TIC is an important part of the transformation of the ancient cyanobiont into a modern chloroplast. I am also interested in recent advances in how science is conducted and displayed (e.g. Open data and Open access publishing). Therefore, I have started documenting my research in an open laboratory notebook that can be found on www.matstopel.se/notebook. My PhD studies where focused on investigating the evolution of the genus Potentilla (Rosaceae). This work involved periods of fieldwork (in Sweden, Russia, Ecuador and USA) in order to study and collect specimens, followed by laboratory work to generate data for phylogenetic studies. The latter made me interested in bioinformatics and large-scale analyses of genetic data, which got me interested in various UNIX-like operating systems (BSD, GNU/Linux, OS X), and high performance computing, and how this can be used in biological science.
