J. A. Scott Kelso (born 1947 in Derry, Northern Ireland) is a neuroscientist, and Professor of Complex Systems and Brain Sciences, Professor of Psychology, Biological Sciences and Biomedical Science at Florida Atlantic University (FAU) in Boca Raton, Florida and The University of Ulster (Magee Campus) in Derry, N. Ireland.
Kelso has worked on coordination dynamics, the science of coordination and on fundamental mechanisms underlying voluntary movements and their relation to the large-scale coordination dynamics of the human brain.
His experimental research in the late 1970s and early 1980s led to the HKB model (Haken–Kelso–Bunz), a mathematical formulation that quantitatively describes and predicts how elementary forms of coordinated behavior arise and change adaptively as a result of nonlinear interactions among components.
Kelso was born in the city of Derry, Northern Ireland. He attended Foyle College (1958–1965), receiving his undergraduate education at Stranmillis University College Belfast from 1965 to 1969, and the University of Calgary, Alberta from 1971 to 1972. He obtained his PhD from the University of Wisconsin, Madison in 1975.
From 1976 to 1978 Kelso was Assistant Professor and Director of The Motor Behavior Laboratory at the University of Iowa. Between 1978 and 1985 he was Senior Research Scientist at Yale University's Haskins Laboratories in New Haven, Connecticut and Professor of Psychology and Biobehavioral Sciences (Unit of Behavioral Genetics) at the University of Connecticut.
