In 1967, at the University of Texas, Thiessen was awarded a five-year Career Development from National Institutes of Mental Health (NIMH) to study gene substitutions on behavior and physiology of mice. Over the years he has held appointments as research article reviewer, editor, or membership in a number of professional organizations, including

In 1969 he received a three-year award by the Russell Sage Foundation to help develop behavior genetic studies at the Center for Behavior Genetics and Evolution at the University of Texas. Beginning in 1970 and lasting approximately 25 years, Thiessen received continuing research support from NIMH to conduct behavior genetic and pheromone research on mice and gerbils. During this period he also served for eight years on NIMH research study committees evaluating research applications for psychological research from NIMH. In 1975 he was awarded research funds from the University Research Institute at the Univ. Texas at Austin. Thiessen is currently Fellow of the American Psychological Association and Fellow of the American Association for the Advancement of Science.
