Paulus was hired as an assistant Cooperative Extension agronomist in the Department of Plant Pathology (now Microbiology and Plant Pathology) at UC Riverside in 1954. Initially, he was one of only two CE plant pathologists in the entire state of California, retiring in 2001 at Full CE Step VIII.
Paulus performed applied research on the underlying mechanisms and control of plant diseases of strawberries, vegetables, ornamentals and subtropical crops. He was well-known for his broad knowledge and ability to tackle a wide range of diseases caused by fungi, oomycetes, viruses and bacteria. His booming voice, quick wit and self-deprecating manner were legendary in the department.
During his 47-year career, Paulus published 248 research and extension articles, book chapters, proceedings and reviews. He was a sought-after consultant, working with universities and governments on six continents. He received the Assembly Council Cooperative Extension Award, the UCR Chancellor's Founder's Award and the Hilgard Award from the Association of Farm Advisors and Specialists. He was also a Fellow of the American Phytopathological Society (APS) and served as President of the APS Pacific Division and as Director and Secretary of the APS Foundation. An APS student award bears his name.
Paulus is survived by his children, Lynda Ross, David Conrad, Diane Perkins and Karen Lake, 12 grandchildren and 12 great-grandchildren.
