Research Description

I study and document plant diversity. At Plant Sciences, my work focuses on the development and implementation of BRAHMS Botanical Research And Herbarium Management System. BRAHMS is a database management system for botanical researchers and herbaria providing wide-ranging functionality to gather, edit, analyse and publish botanical data, optimizing its use for curation and research. An international advisory group was established in 1999. Key BRAHMS project events are documented on: Read more about BRAHMS.
