This blog contains a log of my activities, interests, disinterests and anything I might happen to put on it.

I am a machine learning engineer at Recorded Future. Before joining Recorded Future, I was a postdoctoral researcher in the MMC group at TU Delft. I've dabbled in research mostly related to recommender systems.

Prior to TU Delft I was a Marie Curie (ERCIM ABCDE) fellow at CWI in Amsterdam from April 2013 to March 2014.

From June 2008 to March 2013, I was a Ph.D. student at DAI Lab which is an institute belonging to Technische Universität Berlin. My doctoral dissertation was on the topic of evaluation of recommender systems.

My current work location is Delft, The Netherlands where I've been since April 2014.
