About me

I am a PhD candidate in the Laboratory for Information and Decision Systems (LIDS) at the Massachusetts Institute of Technology (MIT). My research advisors are Prof. John Tsitsiklis and Prof. David Gamarnik.

Before coming to MIT I obtained my Bachelor's and Master's degrees in Electrical Engineering from Universidad ORT Uruguay in 2012 and 2014 respectively.

Research interests: Applied probability, queueing theory and large-scale stochastic decision systems. I am currently studying the fundamental tradeoffs between the availability of dynamic state information and the delay performance of large distributed service systems.
