Sarai Hernandez-Torres

University of British Columbia


I am a PhD candidate working with the probability group in the Department of Mathematics at the University of British Columbia. My supervisors are Omer Angel and Martin Barlow. I am supported by the Mexican National Council for Science and Technology (Consejo Nacional de Ciencia y TecnologĂ­a, CONACYT ).

Prior to this, I completed my M.Sc. in Mathematics at UBC under the supervision of Martin Barlow. I got my B.Sc. in Mathematics at University of Guanajuato / CIMAT in Mexico.

Here is my CV

Research interests

My research is on discrete probability. I am interested in stochastic models defined over combinatorial structures, such as random walks, random trees, and competitive growth processes.

I am drawn to questions on the large-scale behavior of discrete random processes, and also on their rigorous connections to continuous models through the scaling limit.

The Continuum Random Tree (aka CRT or Brownian CRT) is my favorite random object.


  1. Scaling limit of the three-dimensional uniform spanning tree and the associated random walk,
    with Omer Angel, David Croydon and Daisuke Shiraishi. In preparation.
  2. Chase-escape with death on trees,
    with Erin Beckman, Keisha Cook, Nicole Eikmeier and Matthew Junge. Preprint.
