Curriculum vitae

Work experience

January 2011 - Present

PhD-Student at the Institute for Systematic Botany and Ecology

The key focus of my PhD-thesis was on the structure and function of bordered pits in water conducting cells of vascular plants. Key findings of my thesis were that (1) pectins and other acidic polysaccharides do not occur in the intervessel pit membranes, and (2) similar hydraulic efficiency and safety trait-offs are found in angiosperms and ferns.

April 2013 – May 2013

Academic stay at the California State University, Fullerton (California, USA) 

During this stay I developed a protocol to stain vessel associated cells in xylem. This was part of a joint NSF-project “Air out, water in” (Primary Investigator Prof. Dr. Schenk California State University Fullerton, California, USA)

May 2011

Internship in the Cell Wall Lab of Leeds university (UK)

I applied antibodies against pectic and other acidic polysaccharides for immunolocalisation of xylem tissue.

March 2009 - May 2009

Internship in the institute of Chemical sciences and engineering at the école polytechnique fédéderal de Lausanne (Switzerland)

In this position it was my task to measure the efficiency of immobilized transgluamin acid with Snap- and Clip-tag. As project leader I had to use modern labelling techniques effectively, to work independently and to make use of my organizational skills.

December 2008 - February 2009

Tutor at the molecular biology internship for master students (Ulm University, Germany)

As a tutor, I was responsible for 16 biology and biochemistry students. My duties included guiding the students through experiments, such as the measurement of protein-proteininteraction via the split-ubiquitin-assay. I was also in charge of testing students’ knowledge in form of a colloquium and a protocol.

November 2008 - December 2008

Tutor at the plant morphology and anatomy practical for bachelor students (Ulm University, Germany)

October 2007 - December 2007

Tutor of the botanic Tutorial and Tutor at the plant morphology and anatomy practical for bachelor students (Ulm University, Germany)

November 2006 - February 2006

Tutor at the plant morphology and anatomy practical for bachelor students (Ulm University, Germany)

April 2005

Internship at the centre for beekeeping and apiary Rheinland-Pfalz (Mayen, Germany)

September 2003 - June 2004

Conscript service in the German air force Education and training


Education and Teaching

February 2014
Participation in the workshop “Effiktive Lehre durch motiverte Studierende” (part of the UULM PRO MINT& MED project), Ulm University

 Winter term 2012/2013
“Didaktische Weiterbildung für TutorenInnen der Biologie” and “Expertengestützte Hospitation mit anschließender Beratung” (part of the UULM PRO MINT& MED project), Ulm University


October 2004 - December 2010

Ulm University (Germany) - Diploma in Biology

Diploma-thesis title: “The Formin Bnr1 during the cytokinesis of Saccharomyces cerevisiae”

The key focus of my studies is cell biology. The courses I have completed include genetics, cell biology, pharmacology and toxicology, electron microscopy and economics with a focus on sustainable supply chain management. I am currently completing my thesis in the institute for molecular genetics and cell biology. The aim is to investigate the possible interaction between septins and aktin filaments in yeast.

October 2007 - February 2008

Seminar: “Development, registration and supervision pharmaceuticals”

The seminar was a co-operation program between the University Ulm and Ratiopharm.

First hand information on the experimental and judicative process of development and registration of pharmaceuticals were provident.

February 2007

Sachkunde nach §5 der Chemikalien-Verbotsverordnung

This official recognition of competence based on §5 of the German chemical ban law permits me to sell toxic and sensitive chemicals. It is also testament to the fact that I am competent at handling toxic preparations and substances.

September 1991 - July 2003
