Designed and conducted post-fiight experiments on frogs raised on the Space Shuttle and a Russian BioCosmos satellite.

• Responsible for setup and methodology testing of biological experiments flown in space.

• Developed Macintosh data acquisition software for recording the behaviour of space raised tadpoles (featured in a full page ad in MacWorld magazine, April 1993).
