During my stay at Texas A&M University, I worked on the chemical ecology and behavior of the Imported Red Fire Ant. I primarily investigated the pheromone systems. In addition, nest temperatures were monitoried in relation to sugar balances. Prior to my stay in Texas, my career was developed in Sweden working on bark beetle chemical ecology. In Sweden I also studied red wood ants, Formica aquilonia which can be compared to fire ants in terms of heat maintaince and pheromones.

I obtained my B.S. from Colorado State University in Entomology in 1971, and continued there receiving an M.S. in Entomology in 1973 (with Dr. J. Wayne Brewer). I then began my Ph.D. studies on chemical ecology of Dendroctonus and Ips bark beetles at the University of California at Berkeley in Entomology with Dr. David Wood (Ph.D. 1978). From 1978-1980 there were several shorter postdoctorals at Berkeley on bark beetles (with David Wood), elm bark beetles (with Dr. Pavel Svihra and Carl Koehler in extension Entomology) and entomogenous nematodes (with Dr. George Poinar). In 1981, I started a long postdoctoral in Sweden with Dr. Jan Lfqvist at Lund University on bark beetle pheromones. In 1989 my position became equivalent to associate professor with the title of Docent in 1989. I funded myself on several 3-year grants on research of forest tree-insect interactions at Lund University. In 1995, I moved from Lund University to the Swedish University of Agricultural Sciences at Alnarp (10 km from Lund) and continued with bark beetle ecology, modelling, and plant resistance. In 2001, I came back to the USA to work on fire ants at the Department of Entomology, Texas A&M University, with Dr. Brad Vinson.
