Joaquin Quiñonero Candela. Brief Biography

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. Bernhard Schölkopf

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 machine learning.

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 some Arabic.
