Warren's Master's Degree helped him get employed as a fishery biologist for the U.S. Bureau of Fish and Game at Sandy Hook Marine Laboratory in New Jersey where he researched the behavior of striped bass. He later transitioned to becoming a science educator at the secondary and university level. After his retirement, he continued to work part-time at Liberty Science Center. At the age of 80, he thought it was time for a complete retirement. His wife Ann was also an educator. They currently are involved in establishing pollinator gardens in our community, enjoy biking, and recently celebrated their 50th anniversary. Warren's interest in photography comes in handy when they visit their daughter who is an instructor in Alaska.
