About me

I am a PhD student at the Machine Learning Group in Saarland University, supervised by Matthias Hein. I am currently working on extensions of Spectral Clustering to signed networks and multilayer graphs.

Before starting my PhD studies, I did a M.Sc. in Computer Science at Saarland University together with the International Max Planck Research School for Computer Science.

Prior to that, I did a B.Sc. in Applied Mathematics at Instituto Tecnológico Autónomo de México (ITAM). During my B.Sc. I had the wonderful opportunity of doing two internships at the Fraunhofer Institute for Digital Media Technology (Fraunhofer IDMT).

[15/October/19] I will be visiting The Computer Laboratory at University of Cambridge for one week: 11-15 of November 2019.

[03/September/19] Our paper Generalized Matrix Means for Semi-Supervised Learning with Multilayer Graphs got accepted at NeurIPS 2019.

[08/June/19] Our paper Node Classification for Signed Social Networks Using Diffuse Interface Methods together with Jessica Bosch and Martin Stoll has been accepted at ECML PKDD 2019.

[22/April/19] Our paper Spectral Clustering of Signed Graphs via Matrix Power Means got accepted at ICML 2019.

[23/January/19] Invited talk at minisymposium session Information extraction using the graph Laplacian organized by Martin Stoll and Michele Benzi at ICIAM 2019. I will present our work on Matrix Means for Signed and Multilayer Graph Clustering.

[04/August/18] I will be visiting the Alan Turing Institute in London for one week: Monday August 27 to Friday August 31.

[13/July/18] Our paper Community Detection in Networks Via Nonlinear Modularity Eigenvectors got accepted at SIAM J. Applied Mathematics (SIAP).

[08/June/18] Our paper The Power Mean Laplacian for Multilayer Graph Clustering got accepted at the workshop MLG@KDD.

[04/May/18] Talk at minisymposium session Matrix Functions and their Applications at SIAM ALA on Matrix Means for Signed and Multilayer Graph Clustering.
