Regeneromics is a bioinformatics shared resource available to labs of DRC faculty affiliates. It specializes in the genomics of tissue regeneration across many species. Regeneromics is located in Nanaline Duke Room 465, or

Regeneromics is led by Jianhong Ou, PhD and is located in Nanaline Duke, Room 465

Jianhong Ou, PhDJianhong has been at Duke for four years, after serving as the Core Bioinformatician at UMass Medical School. In his 11 years as a Bioinformatician, he has led and assisted over 40 laboratories in a wide range of projects. Jianhong’s areas of greatest interest include data integration and data mining go high-throughput experiments such as microarray, ChIP-chip, ChIP-seq, RNA-seq, MiRNA-seq, iCLIP-seq/HIST-seq, ATAC-seq, and scRNA-seq for transcriptional regulation and post-transcriptional regulation. He develops and applies computational tools (R/Bioconductor package) to analyze and integrate various data sources. Jianhong can bring considerable computational and analytic resources to alleviate the heavy tasks of research projects and assist grant applications and manuscripts. Please bee description below.


The RNI Regeneromics Shared Resource will strive to provide cutting edge data analysis through published and novel pipelines.

The key services are, but not limited to, high-throughput data analysis, data visualization, grant support by data mining from published data, and customized pipeline and tools development.

There are three stages for onboarding projects: initial a project with an estimate of the cost and time of completion, data analysis and communication, and results delivery.  The shared resource will ask affiliated labs using the services to list the resource in the acknowledgements of publications, or authorship based on effort.

The shared resource collaborates with CoreResearch@Duke to provide billing support. This will remove the barrier of payment.

Please email consultation or further information.

Contribution to Science

As a collaborator, the shared resource development tools and pipelines to meet the fast-development requirements of new emerging high-throughput techniques. To help researchers meet the goal of increasing the reproducibility of scientific findings, the pipelines were build using Nextflow, a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It includes docker containers, making installation trivial and results highly reproducible.

With the help of the bioinformatic analysis, affiliated labs successfully completed multiple research projects and produced multiple peer-reviewed publications in high impact journals.
