Information retrieval and ranking for computational models
Modelling biological systems is necessary to characterize biological phenomena and to study the behavior of biological systems. As the science is developing day by day, the number of models is rising too. Therefore searching for models is becoming more and more important. Models can be searched by different aspects. For example we can search models by keywords or by certain structures. Models can be searched by their ontology terms too. However, as we are to optimize methods to search for models, combining search results is equally important.
From this perspective, we are interested in how to create a metric to combine results from our current ranked retrieval into a single similarity score.

Identifying White Blood Cells using Machine Learning
Identifying the number of different white blood cells (WBC) in human blood is an established clinical routine, where WBC are labeled with fluorescent markers.
I work on a novel approach based on machine learning where WBC are identified label-free, i.e., without any markers.
I am developing an open-source workflow that seamlessly connects the recorded images from the instruments with machine learning. The goal is a presentation of the results relevant for clinicians.
This enables fast, cheap and highly accurate identification of WBC, without destroying the cells and leaves marker channels free to answer other biological questions.

FlowML: Diagnostic Tools for Image-Based Flow Cytometry using Machine Learning

Imaging flow cytometry(IFC) captures multichannel images of hundreds of thousands of single cells within minutes. IFC is seeing a paradigm shift from low- to high-information-content analysis, driven partly by deep learning algorithms. We predict a wealth of applications with potential translation into clinical practice.
