My PhD is in agronomy. I worked as an international maize breeder between 1981 and 1988 with CIMMYT and Pioneer Overseas Corporation. I was a post-doc with the CIMMYT maize program in 1981-2, and I started a breeding program targeting mexico and central america for Pioneer in 1983-4. I returned to CIMMYT in 1985 to be posted to Zimbabwe where I built the Mid-Altitude Maize Research Station and started our maize breeding efforts for Southern Africa. During that time I helped Malawi's NARS transition to semi-dent maize hybrids. From 1989 until 2006 I held a tenure track faculty position at Michigan State University where I was the wheat breeder in the department of Crop and Soil Sciences. I had a 75% research, 25% teaching appointment but I also did outreach/extension. I was promoted to associate professor and granted tenure in 1995. While at MSU, I taught Plant Genetics, Plant Breeding, and Quantitative Genetics. At MSU I also helped design and manage the "Wheat 2000" project that led to widespread increase in the productivity of wheat in Michigan through better crop management. Later I co-founded and then managed for 8 years the US Wheat and Barley Scab Initiative (www.scabusa.org). At MSU I released several wheat varieties, five of which are still grown in Canada or the US. During my last year at MSU I helped launch the Global Rust Initiative (www.globalrust.org). I left MSU in 2006 to again return to CIMMYT where I helped develop the Borlaug Global Rust Initiative and the proposal for the BMGF-funded, Durable Rust Resistance in Wheat project (DRRW). I visited Kenya and Ethiopia several times a year to initiate the rust screening facilities that continue to serve world wheat improvement efforts. I left CIMMYT in 2008 to help Cornell launch the DRRW (www.wheatrust.cornell.edu). The DRRW consortia included scientists in 15 institutions in 13 countries. I returned to CIMMYT in 2010 to work and live first in Afghanistan and then Pakistan, where I helped design and manage the Pakistan Wheat Productivity Enhancement Program (WPEP, http://wpepforpakistan.org/) funded by USDA. IN Pakistan I also co-developed and led for one year the new, USAID-funded Agricultural Innovation Program (AIP) for Pakistan. Since mid-2012 I have worked from the University of Minnesota’s Department of Plant Pathology where I have a courtesy appointment as visiting associate professor.
