Profile

I started my research in chemoinformatics in the University of Bonn doing the MSc Life Science Informatics. For my masters thesis I developed the first multi-target activity landscape (visualizations that showed both structural and biochemical information of molecules) that could scale to large number of targets.

I did my PhD in the same university from 2012 to 2016. My thesis focused on data mining and visualization of complex chemical data sets. I also gained experience in machine learning and molecular modelling during my time in Bonn.

After I obtained my PhD, I went to the University of Sheffield as a Marie Curie postdoctoral researcher. There I worked for the EU project D3i4AD, developing multi-task machine learning models based on deep neural networks and matrix factorization techniques to support phenotypic screening campaigns.

I became a Lecturer in Chemoinformatics in the Information School in October 2018.

Research interests

Computational techniques to support decision making are becoming more prevalent in chemical and pharmacological research. I am interested in different aspects of how these techniques can contribute to drug discovery research:

  • Machine learning model interpretation: machine learning models create associations between structural elements of sets of molecules and biochemical properties that are expensive to measure. However, in many cases it is not possible to know what these associations are. I am interested in techniques that are able to make these models more understandable.
  • Visualization of chemical space: visualization techniques are a useful way to condense a large amount of information in an understandable fashion. I am interested in developing novel visualizations that bridge the structural information of sets of molecules to their physico-chemical and biochemical properties.
