## Welcome to my webpage

I am an Assistant Professor at the Departamento de Matemáticas at Universidad Andrés Bello in Santiago, Chile. I am also associated researcher of the Center of Mathematical Modeling (CMM) and adjoint researcher of the Núcleo Milenio de Información y Coordinación en Redes .

I obtained my Ph.D degree from Universidad de Chile and Charles University of Prague. My advisors were Martín Matamala and Martin Loebl .
