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. Recently I obtained a PhD degree at the Aix-Marseille Universite in Marseille, France. Currenly I am working as a post-doctoral researcher at Anthony Mathelier's lab.

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. Currently I'm an active developer of RSAT which is a collections of tools to analize Cis-Regulatory sequences.

Current Projects

  1. 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 (i.e. motifs dicovered with different tools) and manually or automatically reduce the redundancy.

  2. RSAT position-scan: a tool to detect Transcription Factors positionally biased in sequences (e.g. centered around ChIP-seq peak summits, located near TSS).


    This tool separates the type of positional profiles which allows to identify enrichment or depletion of TF binding sites at certain positions of a set of sequences with the same length.

  3. RSAT matrix-enrichment: a tool to detect gloablly enriched or depleted Transcription Factors in a set of sequences.


    The TF enrichment can be measured simultaneously in several set of sequences.

  4. Using the tool RSAT matrix-enrichment I have merged several complete databases with motifs from different taxa (vertebrates, plants and insects) in order to create automatically non-redundant taxon-wise motifs collection.


    This databases and other examples ara available in this link. In the future I will include the databases for worms, fungi and bacteria.
