I am an Assistant Professor in the Department of Ecology & Evolutionary Biology and the Microbial Sciences Institute at Yale. I did my Doctoral and Postdoctoral training at Brandeis and MIT, where I had the fortune to work with Jane Kondev and Jeff Gelles in bacterial gene regulation, and with Jeff Gore on eco-evolutionary and population dynamics of budding yeast. Right before coming to Yale, I started an independent research lab at the Rowland Institute at Harvard. My professional CV can be found here. As a PI, I strive to create a highly collaborative environment where people have ownership and control over their projects and their time. I grew up in the beautiful Castilian towns of Zamora and Salamanca, in the northwest of Spain right by the border of Portugal (a little-known but extraordinarily beautiful -and very much worth a visit!- region of Europe). I have also lived and worked in Madrid, Geneva, the Twin Cities and, for the past fifteen years, in various towns and cities in New England.

At Yale I have taught:

  • EEB 225 - Evolutionary Biology,

  • EEB 678 - Mathematical Models in Ecology & Evolution, and

  • EEB 729 - Microbial Ecology & Evolution.

In the summer of 2019 I will be a Lecturer at the Physical Biology of the Cell Summer Course at the Marine Biology Laboratory at Woods Hole, where I will lead a Theory rotation together with the two graduate students in the lab as TAs.

In the Fall of 2019 I will teach EEB 729 again. This year we will focus on the directed evolution of whole communities as a vehicle to learn about how microbial communities assemble and how they function. To that end, we will cover topics such as microbial community coalescence, priority effects, eco-evolutionary dynamics, microbial metabolic networks, etc. If you are a Yale student interested in taking part and want to know more, please feel free to contact me.
