Expert advice

Over 10 years' experience in open data, data interoperability, and research data sharing. I've worked in academia, government, private sector and non-profits, covering data sharing from pretty much every angle. I can advise on using or producing open data, developing data standards, or how to approach a data or mapping problem.
