Jan Torgersen
Background and activities
Jan Torgersen is Associate Professor of Mechanical Engineering at the Norwegian University of Science and Technology (NTNU) and Visiting Professor of Mechanical Engineering at Stanford University. He is part of the Outstanding Academic Research Fellow Program and NTNU and the director of the Micro- and Nanoscale Design laboratory. Torgersen studied Mechanical and Industrial Engineering at the Vienna University of Science and Technology (TU Wien), where he joined the Institute of Materials Science for his Master and PhD. He was instrumental in the structuring hydrogels with two photon polymerization, a high resolution lithography based additive manufacturing technique capable of fabricating 3D features over multiple length scales. He pioneered in the fabrication of tissue engineering scaffolds direct in the presence of cells and living organisms to provide a dynamic cell culture environment. His interest in the interplay between shape and surface functionality in the Nano- and Mesoscale led him to pursue his post doctoral work at the Nanoscale Prototyping Laboratory at Stanford University, where he explored issues on energy conversion and storage working on thin film capacitors for DRAM applications, buffer layers for solar cells and catalytic layers for fuel cells. At NTNU Trondheim, he continues to work on the interplay between surface functionality and topology, where his current research interests lie in biomedical materials and energy conversion devices.
