Bio

Miguel has a Ph.D. in computer science and bioinformatics. He learned about data mining 20 years ago and discovered a great field of application in Bioinformatics. Since then, Miguel has worked in many areas focusing on cancer genomics (text-mining, systems biology, web development, and workflows). He has written hundreds of thousands of lines of open-source code and developed the Rbbt framework, one of the most effective tools for data analysis, downloaded over a million times.

Work Experience

Head of Unit

2017 - PRESENT

Barcelona Supercomputing Center

Developed a suite of bioinformatics pipelines covering a wide range of functionalities: DNA and RNA-Seq alignment, variant calling, quantification, clonality, cohort statistics (cancer drivers, survival, etc.), drug response, synergies, modelling...
Contributed to the development of my own bioinformatics framework (Rbbt) with functionalities improving integration on HPC: Flexible and elastic resource allocation, and automatic deployment of heterogeneous workloads across sites and containers.
Developed interactive web portals to visualize terabytes of genomics data, with secure policies respecting data privacy. Integrated and developed multiple data visualization frameworks to explore the multiple data types. On-demand analyses.

Postdoctoral Researcher

2016 - 2019

Norwegian University of Science and Technology

Developed a complex pipeline for the prioritization of targeted drug combination treatments for cancer based on integrative analysis of multiple genomics data sources, Bayesian statistics modeling, and Boolean cell signaling simulations.
Created a comprehensive resource for gene transcription regulation information based on our own text mining and integration with multiple curated database resources. Resolved cross-species integration, normalization issues, and quality assessment.
Built a tool to assess drug synergies across arrow drug sensitivity assays implementing the most used statistics: CI, Bliss, HSA, etc. Produced interactive plots. Support for massive execution batches using HPC and the Rbbt workflow enactment.

Postdoctoral Researcher

2010 - 2016

Spanish National Cancer Center

Released own bioinformatics framework Rbbt (Ruby Bioinformatics Toolkit). Arguably, it's the most comprehensive framework for developing bioinformatics applications. The core package (rbbt-util) has been downloaded more than 1.2 million times.
Made essential contributions to the Pancancer Analysis of Whole Genomes (PCAWG), an international project: Web data visualization portals, functional annotation of variants, driver predictions, and pathway enrichment analyses (statistics).
Developed a workflow enactment engine for Rbbt with many advanced features not present in competing solutions: cmdline + HTML + web services, multi-step forking streaming API, HTTP hijacking, and elastic concurrency.

Teaching Assistant

2005 - 2010

Universidad Complutense de Madrid

Developed Rbbt (Ruby Bioinformatics Toolkit) incrementally through the different projects I was involved with. Support for data processing, text-mining, and web development, among other things.
Developed several bioinformatics web applications: Text-mining for the functional description of gene lists through NMF, functional enrichment analyses of genes and proteins across multiple databases, and named-entity recognition and normalization.
Produced the first SOAP and REST web services for the different projects in my group.

Freelance Junior Programmer

2002 - 2005

Several Business

Contributed to the development of the system used by Jazztel to manage internal orders and provisions using Java Spring.
Build a tool to extract all literal strings of text in code and replace them with dictionary entries to support the localization of a large web application for car rental.
Developed a clustering model to process survey responses in a sociological study.

Technologies: Perl, Java, Programming, Frameworks, Clustering

Experience

Ruby Bioinformatics Toolkit

http://mikisvaz.github.io/rbbt/

Arguably the most comprehensive toolkit for bioinformatics development. It has been developed for more than a decade. While it has not been actively promoted and is used internally, it has been downloaded more than a million times in RubyGems. It consists of several core packages implementing the different base utilities and several dozen different 'workflows' or domain-specific functionalities. Among other things, it features one of the most advanced workflow enactment systems.

The project was developed with bioinformatics in mind, but its functionalities are applicable to any field of data analysis. It has been used in nearly 50 different projects of all sizes, from small utilities to support larger investigations to crucial components of massive international projects.

PCAWG Scout

A comprehensive web data visualization portal for the international project Pancancer Analysis of Whole Genomes. This is one of the most ambitious re-sequencing projects that analyzed many terabytes of genomics data. This portal offers on-demand analyses to explore the data in multiple ways; each analysis can be followed up with further analyses. It features multiple visualization tools such as networks, 3D protein visualization, genome browsers, pathway enrichment analyses, and survival statistics.

Text-mining for Transcription Regulation Information

https://extri.org/

Text-mining system for biomedical articles to extract sentences containing transcription regulation interactions. This work is being followed on projects on molecular system modeling, where this information has proven to improve performance significantly, as well as for the generation of focused curation stacks.
