Hey there, I’m Pablo. I’m involved in a number of projects related to effective altruism, longtermism, and forecasting.


I’ve been part of the effective altruism community since its inception and have collaborated with several EA orgs and people over the years. As Will MacAskill‘s research assistant, I was responsible for much of the background research for Doing Good Better. More recently, I created, edited and wrote most of the content of the Effective Altruism Wiki.

Some of my hobbies include languages, travel, tango, minimalism, and wasting time on my Emacs configuration.

I don’t have a permanent place of residence; as of February 2023, I’m based in Buenos Aires.

Feel free to get in touch. You can also find me on the Effective Altruism Forum and (before I became less active) on Metaculus and LessWrong.

We live during the hinge of history. Given the scientific and technological discoveries of the last two centuries, the world has never changed as fast. We shall soon have even greater powers to transform, not only our surroundings, but ourselves and our successors. If we act wisely in the next few centuries, humanity will survive its most dangerous and decisive period. Our descendants could, if necessary, go elsewhere, spreading through this galaxy. In Nietzsche’s words, there has never been such a new dawn and clear horizon, and such an open sea.
