In brief

I obtained a bachelor degree in Genomic Sciences from the UNAM (Universidad Nacional Autonoma de Mexico) in Cuernavaca, Mexico. After that I moved to France where I obtained a master degree in Systems Biology from the IMaLiS program at the ENS (Ecole normale Superieure) in Paris, France. Also in France I obtained a PhD degree at the Aix-Marseille Universite in Marseille in 2017. From 2017 to 2022 I worked as a post-doctoral researcher at Anthony Mathelier's lab.

Work experience


2022 - Present Norway

Nykopde Threapeutics AS, Oslo, Norway.

Post-doctoral researcher

2017 - 2017 Norway

Centre of Molecular Medicine Norway Oslo, Norway.
Supervisor: Anthony Mathelier.

During this time I worked mainly in a project to associate somatic mutations with changes in gene expression across gene networks in multiple cancer types. Also, I worked in the update of the JASPAR database as a curator and developer. As a side project, I continued working as part of the RSAT team by maintaining the tools I developed and updating the motif databases.


PhD in Bioinformatics

2014 - 2017 France

Aix-Marseille Universite, France.
Supervisor: Jacques van Helden.
(1) Development tools to cluster, align and reduce redundance of Transcription Factors Binding Motifs.
(2) Development of a tool to detect positionally enriched/depleted motifs.
Title: Development of bioinformatics methods for the analysis of large collections of transcription factor binding motifs: positional motif enrichment and motif clustering.

Master degree in Systems Biology

2014 France

École Normale Supérieure Paris, France. Courses taken included: Bioinformatics, Genomics, Logical Modelling, Microscopy, Evolution, Molecular Biology.
Master thesis at Aix-Marseille Université TAGC in the TAGC Laboratory in Marseille, France.
Supervisor: Jacques van Helden.
Title: matrix-clustering: a novel tool to cluster and align Transcription Factor binding motifs.

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.



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 upcoming 2024 release.

Current Projects

    These are the projects I currently work in (whenever possible).

  1. I am part of the JASPAR consortium since 2017. With other colleagues, I lead the curation and development of JASPAR, for the 2020 and 2022 releases. My contributions were 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, and the visualization of the TF motif clusters.


  2. 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.

  3. 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.

    In this repository you can find a faster and stand-alone version (functional but still under active development).
