Dan J. Thoma. Dan J. Thoma (born January 30, 1963) is an American metallurgist who is a Professor in the Department of Materials Science and Engineering at the University of Wisconsin–Madison. He is the director of the Grainger Institute for Engineering at the University of Wisconsin–Madison. Thoma is also a past President of the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME). Thoma is well-known for his research on 3D printing technology, which he has carried out for over two decades.

Education
Thoma attended the University of Cincinnati for his undergraduate studies, and obtained a B.S. in Metallurgical Engineering in 1986. During his undergraduate studies, Thoma was a co-op student at the NASA Lewis Research Center in Cleveland, Ohio. In 1992, he graduated with a Ph.D. in Metallurgical Engineering from the University of Wisconsin–Madison.

Career
From 1992 to 2015, Thoma worked at the Los Alamos National Laboratory in Los Alamos, New Mexico, where he most recently served as the Deputy Division Leader at the Materials Science and Technology Division.

In 2015, he became the inaugural director of the Grainger Institute for Engineering at UW-Madison's College of Engineering. The institute had been initially given a funding of $25 million by the Grainger Foundation in Illinois in 2014. The Grainger Institute for Engineering is currently part of the College of Engineering at UW-Madison.

Thoma's research interests include 3D printing technology, additive manufacturing, materials processing, and alloying theory.

Thoma has received a number of honors and awards, including the 2010 Distinguished Achievement Award from the College of Engineering at the University of Wisconsin–Madison, and 2019 TMS Fellow Award.

Memberships and affiliations
Thoma has been the president of several societies and institutes.

2003: The Minerals, Metals & Materials Society (TMS)
2008: American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME)
2009-2010: Federation of Materials Societies (FMS)

Thoma currently sits on the Advisory Board of Directors of the NASA University Leadership Initiative, the eXtremeMat Technical Advisory Board, the AIME Council of Excellence, the HC Starck Strategic Advisory Council, and the University of California, Irvine Institute for Design and Manufacturing Innovation Advisory Board. Thoma is a former member of the Board of Directors of the Midwest Energy Research Consortium (M-WERC).
