I am an Engineering Director for ads optimization at Facebook. This includes the machine
learning platform used across Facebook to perform rapid experiments,
evaluate new modeling paradigms, and ship and maintain models in
production. It includes building metrics and tools to understand the
economic efficiency of Facebook's ads marketplace, and a dedicated effort
to leverage the machine learning platform to train models that improve the
ranking of ads. My team also keeps malicious ads at bay, and protects
users from poor experiences.
Between 2007 and 2012 I worked for Microsoft. First as a
Researcher at Microsoft Research Cambridge, UK, and then
more recently as a Principal Applied Researcher at
Microsoft Advertising. I have had the pleasure to lead an
amazing team of scientists and engineers, embedded in
Microsoft Research Cambridge. Our work has been focussed
on online advertising on Microsoft's search enging Bing.
We first designed, built and shipped to production adPredictorTM,
an algorithm for prediciting the probability of clicks on
ads. Later on my team shifted focus to the online ads
auction. We worked on algorithms for rapidly tuning
auction parameters from training on terabytes of data. At
Microsoft Research I had the opportunity to ship an Xbox
360 game, The
Path of Go, in collaboration with Thore Graepel,
David Stern, Markus Jost, Ralf Herbrich, Remo Zehnder and
many others. My 5+ years at Microsoft have been an
absolutely wonderful experience, I have learnt amazingly
much both from my managers, my employees and my many
colleagues and friends.
Before joining Microsoft Research Cambridge, between
2004 and 2007 I was a postdoctoral researcher at the
Fraunhofer Institute in Berlin and at the Technical
University of Berlin with Prof. Klaus-Robert Müller.
Before that, I was a postdoctoral researcher at the Max
Planck Institute for Biological Cybernetics in the
beautiful town of Tübingen in Southern Germany, working
with my PhD advisor Dr. Carl E. Rasmussen and with Prof.
I received my PhD from the Technical University of
Denmark in 2004, where I worked for 3 years with Lars Kai
Hansen, Jan Larsen and Ole Winter in the Intelligent
Signal Processing group.
In 2001 I graduated as a Telecommunications Engineer at
the Carlos III University of Madrid, where I worked with
Prof. Aníbal Figueiras-Vidal, who first introduced me to
I was born in Valencia, Spain, and lived since the age
of 3 in Morocco. At the age of 18 I moved to Madrid. I
have been lucky to be able to learn languages, and I am
fluent in Spanish, French, English and German. I can
understand and speak some Danish and can still remember
