Initially Mark Johnston was active in the Field Museum botany department as a graduate student. Johnston’s graduate studies were primarily on the ecology of the Awá indigenous people of Carchi in northern Ecuador bordering Columbia. More recently, Johnston has been doing GIS analyses, remote sensing, database design, and project management work in the private sector. Johnston started in ECCo in 2010 as our Geographic Information Manager where he oversees ECCo's "Tech-Team," geospatial data needs, and performs analysis work.
Johnston received his B.A. in biology from Knox College in 1993, and a Ph.D. in ecology from the University of Illinois at Chicago in 2003.
