I work in a scientific computing group on the CONNJUR project -- 100% open-source software for NMR (Nuclear Magnetic Resonance spectroscopy) software and data integration.

Sub-projects under the CONNJUR umbrella include:

• CONNJUR-ST: Spectrum Translator; for converting time-domain and frequency-domain data between the various formats
• CONNJUR-WB: Workflow Builder; for processing spectral data (time-domain to frequency domain)
• RudolF: a sandbox for applying functional programming languages to NMR, data analysis, and protein bioinformatics. Currently we have Haskell and Clojure code, but are looking to add more languages!

Typical CONNJUR technologies:

• Java
• MySQL
• github
• CVS
• Eclipse
