Cristina Paulino

Assistant Professor Head of the cryo-EM unit since 2017 c.paulino(at)rug.nl

Cristina Paulino, originally from Portugal, studied biochemistry at the Heinrich-Heine University in Dusseldorf, Germany. She conducted her Master Thesis at the Max-Planck Institute of Molecular Physiology in Dortmund, Germany, and graduated in 2008. During her undergraduate and following doctoral studies at the Max-Planck Institute of Biophysics in Frankfurt, Germany, she was trained in membrane protein biology. Under the supervision of Werner Kühlbrandt, a pioneer in the field, she became proficient in electron cryo-microscopy (cryo-EM) and obtained her PhD with distinction in 2014. Building upon her expertise, she implemented the technique of cryo-EM in the group of Raimund Dutzler (University of Zurich, Switzerland) during her postdoctoral studies. In 2017 she obtained a tenure-tracked position as an Assistant Professor and became head of the cryo-EM unit at the University of Groningen. Cristina was awarded with a PhD Fellowship from the Portuguese Science and Technology Foundation FCT, a Postdoc Fellowship from the University of Zurich, a Marie Skłodowska-Curie Individual Fellowships, a NWO Veni grant and a NWO Start-Up grant. Her interdisciplinary research combines structural data, determined by high-resolution single particle cryo-EM, with the functional characterization of target proteins. Her main interest is focused on elucidating the structure-function relationships that explain the mechanism of action of membrane transporters and channels. Apart from science Cristina is a devoted mentor and advocate for women in science. Read more about her here: Biophysics Profile or download her CV

THE GOLDEN TROPHY

The golden EM trophy, is one of the things we introduced in our group to show appreciation and boost the motivation within oneself and between lab members. This trophy is passed to everyone in the group that had a nice accomplishment (published, unpublished, for research or a big life event, or simply for a great idea or support). This event gets a spot on our ‘wall of fame’, which hangs next to our ‘wall of shame’, then, hey, mistakes happen, we learn from them and they can be a good reason for a laugh, too…

THE BIG PICTURE

After all we like to join forces and are a big team. Together with the group of Dirk Slotboom and Bert Poolman we build the Membrane Enzymology group, and together with the group of Albert Guskov we are all interested in the same thing: how do membrane proteins work?!
