Hi there!

I work at Unit8, on solving impactful data & AI problems for businesses. Previously, I was lead data scientist at Swisscom, where I was in charge of the Swisscom Mobility Insights Platform and the content of the Swisscom Open Data portal. During this time, among other things, I developed key algorithms, models and software that transform billions of data points generated every day by mobile phones into statistics related to mobility, with high accuracy and at the scale of the country. My main technical interests revolve around algorithms (spatial/graph/networks), machine learning, probabilistic models -- and of course I like to write code. More generally, I enjoy designing solutions with a quantitative edge to relevant problems. I care about projects leaving a positive net impact; I'm especially sensitive to environmental issues.

I got a PhD from EPFL, with Prof. Patrick Thiran. In 2012, I was a visiting researcher at Technicolor in Paris, where I worked on performance prediction for WiFi networks. In 2011, I worked at Deutsche Telekom T-Labs in Berlin, on the design of efficient and distributed spectrum allocation algorithms for wireless networks. Before that, in 2009, I went to work for my Msc thesis at Docomo Innovations in Palo Alto, on the design of scalable routing algorithms.

You can checkout my resume, publications, patents, LinkedIn profile or Kaggle profile. My PhD thesis was nominated by the jury for the EPFL Patrick Denantes Memorial Prize, I received a best paper award at the ACM COSN 2014 conference, as well as a runner-up best paper award at the IEEE ICNP 2014 conference. I was also lucky enough to have some of my work receive media coverage (see below).
