Research interests

My main areas of interest are functional genomics of microbial isolates and communities. Including de-novo assembly, classification and functional specification of bacteria and yeast. During my Master and PhD I focused on microorganisms in biotechnological application, where I was involved in assembly and functional annotation as well as  expression profiling. In the past two years I have  become fascinated by studies on the human and environmental microbiome and its influence on the environment and human health. During that time I was involved in de-novo assembly and detection of novel species from metagenome samples, as well as taxonomic and functional classification of microbial communities.

Educational Activities and Lectures:

E-learning is an essential part of modern education and especially for students who want to pursue higher education in parallel to a business career. For our courses we try to provide our students with the best quality of education while still allowing them to continue their professional  life. Some of our courses are supported in that endeavor by DataCamp, an intuitive learning platform for data science, which offers R, Python and SQL courses through a combination of short expert videos and hands-on-the-keyboard exercises.

Current Projects 

2021 – 2024 Pretty in Pink?

In our new project we will, together with the Academy of fine Arts Vienna, investigate the microbiome of historic buildings. We will focus on halophilic bacteria which colonise historic walls that are enriched in salts due to environmental factors. These bacteria, apart from the physical damage to the building materials, produce pigments that range from rosy to bright pink. 

Samples will be taken in the Virgilkapelle at the center of Vienna, below the Stephansdom, and in an old cloister the Kartause Mauerbach

Wall painting at the Charterhouse Mauerbach, the old cloister represents a typical historic building that is not climate controlled. Several locations can be found where patches of pink are visible.


– In December 2021 the team visited the Charterhouse, to specify locations for sampling


Past Projects:

2016-2019 MetagenApp

The goals of the project were:

  • The development of an analysis application for microbiome whole genome and amplicon data. 
  • The analysis of the change in palm surface microbiome when travelling through the city to investigate how much of the city surface microbiome is transferred to our hands in the frame of 1-2 hours.

Results: the study was conducted and analysed, the results are available on an interactive website:
