I was born and raised in Quito, Ecuador, and moved to Montreal after high school to study at McGill. I stayed in Montreal for the next 10 years, finished my bachelors, worked at a flight simulator company, and then eventually obtained my masters and PhD at McGill, focusing on Reinforcement Learning under the supervision of Doina Precup and Prakash Panangaden. After my PhD I did a 10-month postdoc in Paris before moving to Pittsburgh to join Google. I have worked at Google since 2012, and am currently a staff research Software Developer in Google Brain in Montreal, focusing on fundamental Reinforcement Learning research, Machine Learning and Creativity, and being a regular advocate for increasing the LatinX representation in the research community. Aside from my interest in coding/AI/math, I am an active musician and love running (6 marathons so far, including Boston!).

I have become obsessed with crossword puzzles, specifically the NYT crosswords, since my friend Ralph Crewe gently forced me to start doing them. Although I’m not still at his level, I’ve been working on them daily and getting noticeably better. In doing so I’ve come to realize they are a fantastic mechanism for testing generally capable problem-solving, and in this post would like to explain the various types of challenges they present.
