Based in the Genomics Capital of San Diego, OnRamp BioInformatics provides ROSALIND™, the first-ever genomics analysis platform specifically designed for life science researchers to analyze and interpret datasets, without any prior bioinformatics skills.


Named in honor of pioneering researcher Rosalind Franklin, who made a major contribution to the discovery of the double-helix structure of DNA with her famous photograph 51, OnRamp’s ROSALIND™ platform aims to simplify the practice of genomic data interpretation, so that biologists, researchers and drug developers can harness the potential of genomic information from DNA sequencing to microarrays and mass spec, while reducing costs and increasing productivity.

ROSALIND™ puts the researcher into the driver’s seat of data analysis, and helps to free up valuable time for Bioinformatics Cores to offload standard analyses and focus precious resources on more complex challenges. ROSALIND™ brings bioinformatics analyses to the bench scientist by broadly expanding access to genomic and proteomic technologies for cancer research and precision medicine.

Jeremy Davis-Turak Ph.D

VP of BioInformatics

Jeremy earned his Ph.D. in Bioinformatics and Systems Biology in the lab of Dr. Alexander Hoffmann at UCSD, researching kinetic models of co-transcriptional splicing.  In his studies, Dr. Davis-Turak developed analyses for RNA-seq, nascent RNA-seq, GRO-seq and MNase-seq that were intimately linked with mechanistic models.  He set up the Bioinformatics Core at the San Diego Center for Systems Biology, optimizing pipeline for RNA-seq and ChIP-seq.  

Dr. Davis-Turak also has extensive experience analyzing gene expression data from his time working in the Neurogenetics Laboratory at UCLA, where he became an expert in the analysis of Microarrays, Weighted Gene Coexpression Network Analysis, pathways analyses, gene set enrichment and motif analysis. His ambitious goal of enabling researchers without programming experience to ask quantitative questions led to the development of web portals featuring tools to query relational databases of expression data (microarray and sequencing) and perform on-the-fly computational analyses.
