Bioinformatics Shared Resources

Sanford Burnham Prebys Medical Discovery Institute


Alexey Eroshkin, PhD, Bioinformatics Scientist and the Core Director

  • Microarray, Proteomics and Next-Generation sequencing (SNP, RNA-seq, DNA-seq, CHIP-seq) data analysis: from raw data to biological interpretation (e.g., finding affected pathways and networks). Network reconstruction, biomarker discovery and predictive modeling of disease status, stage etc. CRISPR screening data analysis for identification of essential genes, managing the database of broadly neutralizing HIV-1 antibodies (bNAbs) at, genome mining for new genes, multiple alignments and phylogenetic analysis. As a manager of the Bioinformatics Core I am also evaluating new tools, planning new projects and allocating resources.

Andrew P. Hodges, Ph.D., Bioinformatics Specialist

  • Dr. Hodges implements existing and novel systems biology and machine learning approaches for target and drug discovery in cancer and other diseases. He provides pathway analysis and functional annotation, statistical simulations and synthetic network design, and heterogeneous dataset integration all applied to fundamental and translational research. Andrew incorporates advanced technologies (R/Bioconductor, Cytoscape, NextBio, GenePattern, AracNe/MI, BN+1, etc.) for validating existing and generating new hypotheses. He will be assisting researchers with database mining, network analyses, and selection of the most promising biomarkers and drug targets.​

Vicky Guo (Xiaohui Guo). Part-time support programmer  

  • Installing, testing and adapting public domain bioinformatics tools for further use by the Core/Labs
  • Will use tested tools to analyze PI’s-generated or publicly-available data. 
  • Will modify software tools to tailor PIs needs.

Rachel Berman, summer intern (currently a freshman studying Computer Science at Brown University)  

  • ​Developed Sample Surfer, a program designed to select samples (from a large gene expression data set) that are similar to a given gene signature
  • ​Analyzed NGS data from normal melanocytes and melanoma samples for changes in gene isoforms

Xiayu (Stacy) Huang, PhD, Biostatistician (former member)

  • Statistical data analysis, e.g., calculation of the optimum number of animals needed for the experiment

Roy Williams, PhD, Bioinformatics Specialist (former member)

  • Data analysis (microarray and proteomics) and genome annotation. You might want to ask me questions about methods for analyzing systems biology data and how to view it in a suitable biological context. I have worked with Affymetrix, GeneSpring, MatLab, Bioconductor and related software extensively over the last six years.
