Academic Education:

B.Sc., Mathematics and Integrated Social and Cognitive Psychology (Combined Program), International University Bremen, Germany (2006)

M.Sc., Mathematics, Jacobs University Bremen, Germany (2007)

Dr., Statistics, Jacobs University Bremen, Germany (2010)

Professional Appointments:

Research Associate, Jacobs University Bremen, Germany (2008-2011)

Research Associate, Northeastern University, Boston, MA (2011-)

Research Interests:

My research focuses primarily on exploratory data analysis and mathematical modeling, specifically on the development and application of methods for uncovering emerging patterns and their underlying mechanisms in complex empirical data.

One of the most interesting and relevant applications of mathematical and statistical theory is in the field of biology. My current projects explore the dynamics of the injury response in the spinal cord of the brown ghost knifefish (Apteronotus leptorhynchus) at both cell population level, using systems of partial differential equations, and protein level, using data mining techniques on expression data. Previous work using the same model system includes demonstrating the non-randomness of the chirping behavior exhibited during fish interactions, as well as quantifying and visualizing the spatial distribution of various cell markers within specific regions of interest of the central nervous system.

Before joining the group of Günther Zupanc, I have worked on cluster analysis methods for data with high cardinality and dimensionality and their applications in the construction of visual vocabularies, as well as on concept propagation techniques underpinning the unsupervised annotation of images.

Other Interests:

When not working, I enjoy strolling through the city’s streets and parks, reading, and occasionally drawing, or simply keeping up to date with the latest topics in science and technology.
