Giving a talk at the work shop on the moduli of curves, Stony Brook

About me
I am a Fields-Ontario postdoctoral fellow at University of Waterloo. My postdoc mentor is Matt Satriano. I am mainly interested in tropical geometry, non-Archimedean geometry, and their applications to algebraic and enumerative geometry.

Prior to coming to Waterloo, I spent six months at the thematic program on combinatorial algebraic geometry at the Fields Institute, and was a postdoc at University of Tübingen with Hannah Markwig.
I got a PhD from Yale University in December 2014 under the wise mentorship of Sam Payne. 

Here is a copy of my CV (updated August 2017).
My email address is yoav.len@uwaterloo.ca.

Recent and upcoming math travel:
In case you are in the mood, here is a problem set on divisors on tropical curves (prepared for the mini-course at IMPA). 

Undergraduate research
In summer 2017, I led a project as part of the Fields Undergraduate Summer Research Program.
The project was concerned with finding bi-tangent lines to tropical curves, and lifting them to algebraic bi-tangents. 
Follow this link for more information about the program and all the participating projects. Here is an example computed by my students of a tropical bi-tangent with an unexpected number of lifts. 

Conferences organized
Together with Angie Cueto and Martin Ulirch, we are organizing a special session on algebraic and combinatorial aspects of tropical geometry, at the AMS sectional meeting in Columbus, Ohio in March 2018.
In 2014, Dhruv Ranganathan and I organized the first student conference in tropical geometry in north America, known as STAGS
