Tim Herman - Speaker for Modeling Marvels Webinar

Modeling Methylation in Epigenetics

Presenter: Tim Herman, PhD, Milwaukee School of Engineering & 3D Molecular Designs

Tim Herman, Ph.D. has been a driving force to introduce 3D printing technology to molecular sciences education and academic research communities for 23 years.

He established the Center for BioMolecular Modeling (CBM) at the Milwaukee School of Engineering in 1998. In addition to utilizing several 3D printing technologies, Tim offers professional development courses for science educators and outreach programs to bridge the gap between the research laboratory and science classroom. The CBM has had continuous funding from the National Institutes of Health (NIH) as well as funding from the National Science Foundation.

Tim is founding partner and scientific officer for 3D Molecular Designs (3DMD) which has received eight Small Business Innovative Research grants from NIH and the National Science Foundation to develop innovative educational models and kits. Tim has an innate ability to design hands-on experiences that help students understand key concepts to construct their own foundational knowledge of the molecular world. The CBM and 3DMD work closely together, as sister organizations.

Previously Tim served in the Medical College of Wisconsin Biochemistry Department, where he taught graduate and medical students and directed research programs in areas ranging from the synthesis of chemically cleavable biotin-labeled nucleotide analogs to the development of novel approaches to structure-based drug design. He received his B.S. in Chemistry from the University of Nebraska and his Ph.D. in Biochemistry from Oregon State University. He pursued post-doctoral studies in Molecular Biology at Harvard Medical School.
