I am a Senior Scientist in the Department of Mathematics at ETH Zürich. In my research I develop and apply topological methods to analyze data from a variety of disciplines. These methods either measure the shape of the data set, that is, count the occurrences of patterns within it, or they build a combinatorial representation of its shape that can be combined with other methods. I collaborate with researchers from a variety of fields including topology, algebraic geometry, probability, statistics, and computer science, and also with experimental scientists.
I am the co-director of the Applied Algebraic Topology Research Network, which hosts a weekly Online Seminar. Recordings of our seminar are available at our YouTube Channel, which has over which has over 5900 YouTube subscribers, and averages over 24 hours watched per day.
