I am a postdoc at Vector Institute. Previously, I was a postdoc in the lab of Matthias Bethge in Tübingen and a Ph.D. student at the University of Amsterdam under supervision of Arnold Smeulders. My research mainly focuses on gaining better understanding of open challenges in representation learning and neural decision-making. My background is in physics with a specialization in neuroscience.
One question I find particularly intriguing is that we have little knowledge about why Deep Networks perform so well and
which properties of the data they use to solve given tasks. I am working on understanding and improving
Deep Convolutional Networks by imposing additional structure on them. Carefully structured models can help us to open up the "black-box", so we can draw actual conclusions about what these networks learn, how they learn and when they will fail.
