In 1914, two years before receiving his Ph.D., he left Wisconsin for employment in Pennsylvania. At Pennsylvania State University, he was an instructor from 1914 to 1915 and an assistant professor from 1915 to 1917.

At Cornell University he was a professor and head of the department of dairy industry from 1923 to 1955.[1] At Cornell he held a joint appointment in the department of bacteriology.[2] He was the author or coauthor of more than 100 scientific publications.[1] He did research on streptococci, dairy and food bacteriology, and fermentation.[2]
He was one of the U.S. delegates to the 9th International Dairy Congress held in 1931 in Denmark and delivered a talk on dairy research in Denmark[4] and a talk on dairy research in Kiel.[5] He was the editor-in-chief of the Journal of Bacteriology from 1944 to 1951.[1] From 1947 to 1955 he was a member of the editorial committee of the Annual Review of Microbiology.[6][1]
