Student Success Stories

Joseph Conrad, MA

When Joe first arrived at the University of South Florida to earn my MA degree in History, his goal was to obtain a skill that would provide him with better employment opportunities. Joe began working with Dr. Collins, who also served on his research committee. Joe received a foundation in 3D software and hardware skills which he says gave him the confidence that he could learn any new 3D tool in the future. Dr. Collins provided industry connections for formalized internships and experiences for Joe, who went to work for 3D Systems, Inc.-  at a leading 3D software company – as well as a stint with Direct Dimensions, Inc. of Maryland.

Joe says he developed an appreciation of collaboration working in the CDHGI, since he often worked with students from the Departments of History, Anthropology, Engineering, and Geosciences. The knowledge and experience gained helped Joe to land a job with Direct Dimensions following his graduation, where he worked on visual effects for Hollywood films, 3D scanned objects for major pieces of art, and analyzed airplane components. Joe now continues with his passion for 3D and History, working to digitize collections in 3D for the Smithsonian Institution.

By using an interdisciplinary approach involving petrographic and chemical analyses, he examines the hidden social setting in which pots were manufactured by ancient communities, in order to promote a more diverse interpretation of the past. In 2019, he published his first scientific article and was awarded with the Rust Family Foundation Archaeological Grant. Additionally, he has been awarded by the Mediterranean Archaeological Trust (2017-2019) to perform radiocarbon analysis.
