MSI Principal Investigator Mo Li, an assistant professor in the Department of Electrical and Computer Engineering (College of Science and Engineering), is one of the authors of a paper in the journal Nature Photonics that reveals properties of black phosphorus films that have exciting implications in optics and photonics. Black phosphorus is a stable crystalline form of the element; in thin films of 20 layers of atoms, it shows remarkable properties as a semiconductor. The paper discusses using black-phosphorus films on silicon optical circuits, with performance rivaling that of devices made of germanium.
An article about the paper appears on the University’s Discover blog. You can read the entire paper on the Nature Photonics website. (Nathan Youngblood, Che Chen, Steven J. Koester, and Mo Li. 2015. Waveguide-integrated black phosphorus photodetector with high responsivity and low dark current. Nature Photonics, 10.1038/nphoton.2015.23 [published online ahead of print].)
Professor Li and his group use MSI resources to model and design photonic structures and acoustic devices.

The University of Minnesota Materials Research Science and Engineering Center (MRSEC) has received a $17.8 million grant from the National Science Foundation. Over a dozen MSI Principal Investigators are participating faculty at the Center (see list below). The mission of the Center is to enable “important areas of future technology, ranging from biomedicine, separations, and plastic electronics to security, renewable energy, and information technology” (from the MRSEC website). The U was one of only 12 universities nationwide to receive NSF funding this year for a materials research center.
MSI PIs participating with the MRSEC:
- Associate Professor David Blank, Chemistry
- Professor Stephen Campbell, Electrical and Computer Engineering
- Associate Professor Kevin Dorfman, Chemical Engineering and Materials Science
- Assistant Professor Cari Dutcher, Mechanical Engineering
- Professor Rafael Fernandes, Physics and Astronomy
- Assistant Professor Vivian Ferry, Chemical Engineering and Materials Science
- Associate Professor Christy Haynes, Chemistry
- Assistant Professor Chris Hogan, Mechanical Engineering
- Assistant Professor K. Andre Mkhoyan, Chemical Engineering and Materials Science
- Associate Professor David Morse, Chemical Engineering and Materials Science
- Professor Theresa Reineke, Chemistry
- Professor J. Ilja Siepmann, Chemistry, MSI Fellow
- Professor Renata Wentzcovitch, Chemical Engineering and Materials Science, MSI Fellow

Professor Robert Tranquillo, Head of the Department of Biomedical Engineering (College of Science and Engineering), has been elected a Fellow of the International Academy of Medical and Biological Engineering. This honor is in recognition of his international contributions to the field. Professor Tranquillo’s current project at MSI uses fluid-structure modeling to understand fluid flow in a bioreactor.

Graduate student Julia Quindlen, who is a member of the MSI research group of Professor Victor Barocas (Biomedical Engineering - College of Science and Engineering), has been awarded a 2015-16 Interdisciplinary Doctoral Fellowship. Ms. Quindlen is a fourth-year PhD student. She will be completing her project, “Mechano-to-Neural Transduction of the Pacinian Corpuscle” under the advisement of Professor Barocas and Professor Martha Flanders (Neuroscience - Medical School) at the Institute for Engineering in Medicine.
Ms. Quindlen was a Grand Prize Winner at the 2014 MSI Research Exhibition for her poster “Multi-scale mechanical modeling of the Pacinian corpuscle.”

Professor James Bradeen, an MSI PI and Head of the Department of Plant Pathology (College of Food, Agricultural, and Natural Resource Sciences), is featured in a recent story by the Big Ten Network about the U’s preeminence in developing improved crops for the benefit of the world’s food supply. The story discusses the legacy of Norman Borlaug and the continuing work by U researchers in the field. Professor Bradeen uses MSI to support his genomics research into wild relatives of crop plants, with the goal of discovering the genes that provide these plants with defenses against disease. You can read the BTN story on their website.
