Yohannes is a Rangelands Research Officer with New South Wales Department of Primary Industries based at the Trangie Agricultural Research Centre. He joined New South Wales Agriculture* as a Technical Officer in 1998 and was appointed as a Rangelands Research Officer in 2002.

As a Technical Officer within the CRC for Weed Management Systems, he led a team that undertook a nation-wide weed survey to study the distribution and abundance of major weed species. He is currently involved in several projects that are geared to the management of rangelands in New South Wales including managing climate variability and controlling the spread of Invasive Native Scrub (INS).

*NSW Department of Primary Industries was formed on July 1, 2004 through an amalgamation of NSW Agriculture, NSW Fisheries, State Forests of NSW and the NSW Department of Mineral Resources.
