Welcome
I’m Dumitru Erhan, a 29-year old who lives in San Francisco and works for Yahoo! Labs. I bike, I cook, I'm a bit of a foodie, "I'm a Mac" and I am an aspiring scientist.
Work
I have just completed my PhD at University of Montréal, doing research in the LISA laboratory of Yoshua Bengio. My PhD work was mostly in the emerging field of deep architectures. At Yahoo Labs, I am part of the team that improves Federated Search, the ranking of search results (web, news, movies, shopping etc.) on the Yahoo Search results page.
Cool stuff
