Burkill has pioneered the use of flow cytometry for analysing plankton including, recently, in-situ analyses using submersible cytometers carried on autonomous underwater vehicles. He is currently working on silicon fabricated microflow cytometers. Burkill has authored ~200 publications in journals, books and proceedings arising from participation on 33 cruises in the North and South Atlantic, the Indian Ocean, the Arctic and the Southern Ocean.
