"Nur was der Mensch sieht, begreift er auch"
Human beings can only truly understand things they are able to see
A small light microscope and innumerable excursions to meadows and forests sparked my interest in nature and research when
I was a kid. I was fascinated by the way the microscope enabled me to look at life forms in a raindrop being otherwise
invisible to the human eye.
When I was studying biology at the University of Mainz, a seminar on membrane protein crystallography held by Professor
Claudia Büchel and a subsequent internship in her lab at the Max Planck Institute of Biophysics in Frankfurt drew my
attention to biophysics. As a result I was fascinated by X-ray crystallography and electron microscopy, and decided to
write my diploma thesis on such a topic.
Claudia Büchel introduced me to the lab of Christine Ziegler, who was working in the structural biology department of
Professor Werner Kühlbrandt at the Max Planck Institute for Biophysics. Christine Ziegler gave me the task to conduct X-ray
crystallography and electron microscopy experiments on the membrane protein BetP. This was a very appealing project because
it was giving me the chance to obtain visible insights on BetP and shed light via an atomic structure to its functional
properties that have been examined biochemically in the lab of Professor Reinhard Krämer (Cologne University) for many
years. Besides, my research and an eventual determination of the BetP structure might contribute to a better understanding
of the functionality of this transport protein. This led to my decision to carry on with my X-ray crystallography
experiments in my doctoral thesis.
Not least because I had two excellent mentors at the MPI of Biophysics – Christine Ziegler (head of the BetP project) and
Anke Terwisscha van Scheltinga (X-ray structure analysis) – I succeeded in determining the structure of BetP. I will not
forget the moment when I was looking at the BetP structure and analyzing its biochemical data with my colleagues Vera Ott
and Sascha Niklisch from Cologne University. Having the atomic protein structure in hand, or rather visible for our eyes,
made biochemical results suddenly more understandable because we could see the structural properties and abilities of this
transporter. Having been able to find a visible link between a protein’s structure and its function and therefore
facilitating the understanding of biochemical processes at atomic level – that is what fascinates me about structural
biology. In fact, I think that human beings can only truly understand things they are able to see.
When I had only a year left to finish my doctoral thesis, I applied for a post-doc position in the lab of Professor Axel
Brunger at Stanford University. Here, I was offered the chance to perform structural experiments on synaptic adhesion
proteins and started at the end of 2009 as an EMBO long-term fellow. Although my focus of research has now changed to a
different kind of proteins, I still want to examine the function of these synaptic adhesion proteins on atomic and cellular
levels using X-ray structure analysis and fluorescence microscopy. And I am planning to pursue my career in the area of
basic research because I want to gain fundamental understanding of intercellular processes on both atomic and cellular
level.
