The objective of Dr. Haller's research program is to develop environmentally sound management programs for invasive aquatic plants. This focus includes basic studies on the ecology and biology of native and exotic aquatic plants, as well as research on developing new herbicides for aquatic uses. In addition, extensive work has been conducted on mechanical and biological control utilizing grass carp and studying the environmental impact of weed management techniques.

The U.S. Agency for International Development, through the International Plant Protection Center (IPPC) funded an international assistance and training program at the University of Florida from 1976-1985. As project leader from 1982-1985, Dr Haller led major training and assistance programs in Thailand, the Philippines, Indonesia, Sudan, Egypt, Sri Lanka, Ecuador, Kenya, and other developing nations. He also participated in a National Academy of Sciences review team in Sudan and had an audience with the King of Thailand regarding aquatic resource management.
