Short Description of the Thesis/Topic:
Recent work has suggested that chimpanzees show a characteristic error when presented with problems that require reasoning about 'OR' operations. When presented with the choice between a single cup baited with food (100% option) and two cups, one of which is baited (50% option), chimpanzees will surprisingly not choose the 100% option above chance. Recent work has shown that kea parrots have a sophisticated understanding of probability (Bastos & Taylor 2021). This study will examine if kea show better performance than chimpanzees when presented with this task

Required Skills and Knowledge:
None. We will teach you how to work with our birds, and give instructions for your literature research. The work is directly supervised on site.

Additional Information:
This diploma thesis work is part of collaboration with Prof Alex Taylor, und thus contractually bound to the winter semester. There are two topics that will be investigated in the WS 2025. The work involves assisting postdoc Millie Johnston in collecting data, in cognition tasks with the kea at Haidlhof, 4 days a week. The plan is to combine the work of both topics, and to then divide it between two people. Each person will have their own topic to write up in their thesis, but this will allow the work to be structured more flexibly.

Duration of the thesis:
01.10.2025 to 28.02.2026

Language of the Thesis:

Short Description of the Thesis/Topic:
Antibiotic resistance is a significant global public health problem threatening the effectiveness of modern medicine. In a cooperative project, the BiMM Research Platform (https://www.bimm-research.at) has identified a candidate substance from a secific bacterium that can break the resistance against a popular class of antibiotic used in human and veterinary medicine. This substance should now be isolated and characterized in this Master Thesis project with part-time employment. The work will include the following tasks:
- bacterial genome sequencing and genome analysis
- optimization of production conditions
- activity-guided isolation by analytical and preparative HPLC combined with microbiological  resistance tests

Required Skills and Knowledge:
If you are interested in the molecular genetics of microbes and bioactive microbial substances, if you have a solid background in molecular biology and biochemistry and you would like to work in a collaborative, interdisciplinary project in a scientifically and socially stimulating working atmosphere, then please apply for this position.

Additional Information:
The work will mainly be carried out in the laboratories of the IMiG at the BOKU Campus Tulln (https://boku.ac.at/agri/imig/arbeitsgruppe-strauss), part of the work will happen at the Vetmed (https://www.vetmeduni.ac.at/lebensmittelmikrobiologie/ueber-uns/team-kathrin-kober-rychli) in Vienna.

Language of the Thesis:

Short Description of the Thesis/Topic:
Colitis is a frequent and serious problem in horses as well as humans. The pathophysiological mechanisms are supposed to involve a complex crosstalk between immune cells and epithelial cells that results in destruction of the epithelial barrier and further progression of disease. This project aims to establish a co-culture model of equine colon epithelium and immune cells to characterize the signalling pathways involved and to test new therapeutic approaches.

Required Skills and Knowledge:
High motivation, experience in cell culture work and/or molecular biology;  
BSc degree in Biology, Molecular Biology, Biotechnology, Biomedicine or a related subject 

Further Information:
We offer a highly supportive team, established methods and guidance by supervisor and colleagues.

Language of the Thesis:
German or English

Duration of the thesis:
6 months

Name of the Institute/Clinic/Unit:
Institute of Physiology, Pathophysiology and Biophysics, Department of Biomedical Sciences & Clinic for Horses, University of Veterinary Medicine Vienna

Short Description of the Thesis/Topic:

Topics include:
    •    The role of deleterious mutations for adaptation and maintenance of variation.
    •    Long-term adaptation of local Drosophila populations.
    •    The evolution of ageing.
    •    Inference of selection signatures from time-series data.
    •    Studying the genotype-phenotype map.

Required Skills and Knowledge:
Over the past years, Vienna has developed into one of the leading centres of population genetics. The Vienna Graduate School of Population Genetics has been founded to provide a training opportunity for PhD students to build on this excellent on-site expertise.

We invite applications from highly motivated and outstanding students with a love for evolutionary research and a background in one of the following disciplines: evolutionary genetics, functional genetics, theoretical or experimental population genetics, bioinformatics, mathematics, statistics.
 

Additional Information:
Only complete applications (application form, CV, motivation letter, university certificates, indication of the two preferred topics in a single pdf) received by 14 May 2025 will be considered. Two letters of recommendation need to be sent directly by the referees.

PhD students will receive a monthly salary based on currently € 2.464,80 before tax according to the regulations of the Austrian Science Fund (FWF).

All information about the about available topics, the training program and the application procedure can be found at www.popgen-vienna.at
