In brief

I obtained a bachelor degree in Genomic Sciences from the UNAM (Universidad Nacional autonoma de Mexico) in Cuernavaca, Mexico. I have a master degree in Systems Biology from the IMaLiS program at the ENS (Ecole normale Superieure) in Paris, France. I obtained a PhD degree at the Aix-Marseille Universite in Marseille, France in 2017. Currenly I am working as a post-doctoral researcher at Anthony Mathelier's lab. My research projects is focused on the characterization of mutations dysregulating miRNA networks and I am also contributing to the next JASPAR motif database release.

Bachelor in Genomic Sciences

2009 - 2013Mexico

I did a research project at the Computational Genomics Lab, Centro de Ciencias Genómicas, UNAM, Cuernavaca, Mexico.
Supervisors : Julio Collado-Vides & Alejandra Medina-Rivera.
"Prediction of novel regulons based on several properties of the regulatory network." Based in that most knowns TFs in E. coli K12 are autorregulated, we searched the motifs for the unknown TFs. (Ongoing project).



My projects are focused on Bioinformatics of Transcriptional regulation (as user and developer), mainly in algorithms to discover Transcription Factor Binding Motifs and to predict Transcription Factor Binding Sites and in the miRNa transcriptional regulation. Currently I'm an active developer of RSAT which is a collections of tools to analize Cis-Regulatory sequences and I am also involved in the JASPAR database, as curator and processing data for the next release.

Current Projects

  1. My main project in my post-doc is the study of mutations in TFBSs associated to miRNAs, and find potential cancer driver miRNAs. In a nutshell, I am applying a bayesian network to highlight mutations in TFBSs with a high association to the dysregulation of the miRNA-target genes. I apply this methods to seven cohorts of TCGA.

  2. I am part of the JASPAR consortium. My job contribution was to develop a workflow (using Snakemake) to ease the motif curation. This workflow performs the motif discovery and the ChIp-seq centrality enrichment score calculation; I am also behind the motif curation processes and motif clustering visualization.


  3. I am an active developer of the Regulatory Sequences Analysis Tools RSAT that is a modular software suite for the analysis of cis-regulatory elements in genome sequences (ChIP-seq, ATAC-seq).


    We are working in a new release of RSAT with new programs.

  4. RSAT matrix-clustering: a tool to cluster, align and create non-redundant collections of Transcription Facotr Binding Motifs.


    This tool can merge different files containing TF binding motifs (i.e. motifs dicovered with different tools) and manually or automatically reduce the redundancy.

    I recently extended the algorithm to generate radial (circular) tress including link to databases, some examples can be found on the JASPAR website.

    The matrix-clustering paper can be found on this link.

    I am actively maintaining this tool, send me an email in case you want to report a problem.
