 Dr Chris Fields

chris web

Technical Lead in Genome Informatics: Christopher's focus is architecting and developing infrastructure within the HPCBio group for genomic analyses; this includes implementations of web-based tools such as GBrowse,and Galaxy and high-throughput analysis pipelines for whole genome annotation such as MAKER and Interproscan, and custom solutions based on a project’s particular needs. He coordinates with the IGB Computer Network Resource Groups and the Galaxy project on code optimizations for server-side scalability and cluster job submission, with the final end-goal being a working Galaxy instance at the University of Illinois. 
He is also a core developer for the BioPerl project, and an active contributor to the Generic Genome Browser (GBrowse). Furthermore, he is actively collaborating to various open-source projects, specifically projects from the Open Bioinformatics Foundation (such as Biopython, BioRuby, BioJava, and EMBOSS), and resources in the Generic Model Organism Database (GMOD) consortium of projects. He is currently a member of the board of the Open Bioinformatics Foundation (OBF). He earned his undergraduate degree in biology from Baylor University, followed by his PhD in molecular microbiology from the University of North Texas in 2002, the latter primarily in a wet-lab research environment. However, he has always had a strong interest in computational biology, and over the course of his second postdoctoral appointment decided that he wanted to focus completely on computational biology, joining the Institute for Genomic Biology as an IGB Postdoctoral Fellow. As previously alluded to, he also became one of the lead developers of the BioPerl open-source bioinformatics toolkit during his post-graduate research, in 2007. Christopher's experience and background as a BioPerl core developer has led to a number of diverse collaborations over the last several years, including work that led to the standardization for the ubiquitous FASTQ format. His role as a BioPerl developer has also led to mentoring opportunities in the Google Summer of Code for NESCent and four more with the Open Bioinformatics Foundation.
