David Corcoran

David Corcoran, Ph.D.


(919) 613-3392

Director, Genomic Analysis and Bioinformatics Shared Resource

Dr. Corcoran is the founding director of the Genomic Analysis and Bioinformatics Shared Resource. He has over 15 years of experience in computational biology analyzing high-throughput genomic data. With a Ph.D. in Human Genetics and an M.S. in Biostatistics, Dr. Corcoran specializes in collaborating with life science investigators to ensure they receive high quality, accurate, and interpretable results from the analysis of their data.

Wei Chen, Ph.D.


(919) 613-0540

Bioinformatician II

Dr. Chen has been working in bioinformatics since 2000. After graduating from the Interdisciplinary Biological Sciences Program at Northwestern University, Dr. Chen worked in both academia and industry before joining Duke in 2005. He provides bioinformatics support to investigators at the Duke Cancer Institute, with an emphasis on sound data provenance and reproducible analysis. He looks forward to assisting researchers analyze their high-dimensional genomic data.

Helene Kirshner

Hélène Fradin, Ph.D.


(919) 684-4151

Bioinformatician II

Dr. Fradin joined the Genomic Analysis and Bioinformatics Shared Resource in 2017 to provide consultation, training and support for the analysis of the genomic data generated by Duke investigators. She first worked as a telecommunications and computer engineer before deciding to go back to apply her expertise to life sciences. She enjoys being able to take part in the innovative research conducted at Duke.

Joseph Prinz


Bioinformatician I

Joseph Prinz is a computational biologist conducting high-throughput data-analysis. As a contributing member of the modENCODE consortium, he had the opportunity to work at the forefront of genomics, developing statistical-learning approaches to next-generation sequencing data-analysis. Prinz joined the core in winter 2014 and looks forward to helping investigators better understand their data.

Jen. M headshot

Jennifer Modliszewski


(919) 684-6730

Bioinformatician II
Dr. Modliszewski joined the Genomic Analysis and Bioinformatics Shared Resource in September 2017.  Her focus at the core includes multi-omics integrative analysis, genome assembly, and microbiome analysis.  Prior to joining the core, she researched the genetics of plasticity in meiotic recombination in Arabidopsis (UNC-Chapel Hill), and she studied the consequences of meiotic recombination in the hybrid tetraploid wildflower Mimulus sookensis during the course of her Ph.D. (Duke).  As an undergraduate alumna of North Carolina State University, she has experienced the unique joys of all three major universities in the Triangle and is happy to be at Duke.
