Dr. Taylor is a research scientist (2003-present) serving in the areas of systems biology and bioinformatics. Dr. Taylor is currently working in the analysis of bacterial communities, in metabolic modeling of bacteria, in analysis of next generation sequencing data (including metatranscriptomics), in inference of biological networks, in the application of high-performance computing techniques to analysis of high-throughput data, and in the construction of scalable databases suitable for data integration and integrated analysis of terabyte-size data sets.
While at PNNL, Dr. Taylor has served as Principal Investigator (PI) for the Complex Queries and Data Structures projects. Also, he was the PI on PNNL's Software Environment for BIological Network Inference (SEBINI) project (Taylor et al., 2006), which provided an interactive environment for the deployment and evaluation of algorithms used to reconstruct the structure of biological regulatory and interaction networks.
Dr. Taylor's 2003 dissertation focused on inference of regulatory networks using information-theoretic methods on correlations in gene expression data, and Dr. Taylor has since have performed substantial work in inference of regulatory networks at PNNL. He has published extensively on the application of computational techniques in network inference in biology as well as the analysis of integrated heterogeneous data sets (Taylor et al., 2013)
Dr. Taylor has served as the architect and administrator of a pilot PNNL project that has implemented a parallel processing/scalable database framework for high volume biological data sets using the open source fault-tolerant Hadoop framework and the HBase NoSQL database, operating on top of Hadoop. This data warehouse now resides on PNNL's Large Scale Analytics Linux cluster. Also, Dr. Taylor published the first general review of Hadoop and HBase use in bioinformatics in 2010 (Taylor, 2010), and has been an invited speaker to talk in this area, as well as a journal reviewer. He is now exploring a Spark-based environment for parallelized distributed graph / topological analysis & querying of large biological networks.
In other current research, Dr. Taylor works closely with the U. S. Department of Energy's systems biology KnowledgeBase (KBase) group, performing gene calling, genome annotation, metabolic model construction, bacterial community analysis and programming in that environment.
Also, Dr. Taylor has helped develop data standards for biological data (e.g., MIAME, MAGE, MISFISHIE, MINSEQE) as an officer and board member since 2000 of the Functional Genomics Data (FGED) Society.
From 2000-2003, Dr. Taylor served as director of gene expression analysis in the Center for Computational Pharmacology at the University of Colorado Health Sciences Center (UCHSC). Before that, he served as a computer scientist at the National Institutes of Health (1991-2000, ending rank GS-14). Dr. Taylor worked first in the BioInformatics & Molecular Analysis Section (BIMAS) at the Division of Computer Research & Technology/NIH and then at the National Cancer Institute/NIH, where he was a senior investigator in the Biometric Research Branch/NCI with responsibility for the design and development of computer systems to handle high-throughput gene expression analysis and analysis of genome and gene expression data to identify and clarify the function of cancer-associated genes.
Dr. Taylor worked on knowledgebase design (automated reasoning, use of ontologies) while at UCHSC, and he created one of the first knowledgebases at NIH, installing the object-oriented Genobase knowledgebase from Argonne National Laboratory while working at BIMAS/DCRT/NIH, adding a web interface and additional public data sets.
Dr. Taylor enjoys building tools and environments that can manage, query, and perform automated reasoning/inference on truly large biological data (e.g., on "Big Data").
- Reconstruction of biological networks, with development of algorithms for inference of regulatory networks focused on information-theoretic and graphical model (Bayesian network) approaches.
- Metabolic modeling of bacteria and bacterial communities, including flux balance analysis and metabolic pathway flux prediction using NMR and mass spectrometry Carbon-13 labeling.
- Integrated analysis of high-throughput gene expression and protein abundance data; analysis of next-generation sequencing data sets. Most recently, metatranscriptomics analysis of bacterial communities.
- High-performance computing techniques (e.g., Hadoop, HBase, Spark platforms on Linux clusters) for large-scale data analysis and construction of data warehouses.
- Automated reasoning and machine learning techniques as applied to joint analysis of regulatory networks, metabolic pathways, and genomic data.
- Biological database and knowledgebase design.
