Geoffrey Beach

Biography

Geoffrey Beach is a Professor of Materials Science and Engineering at MIT.  He received a B.S. in Physics from Caltech, a Ph.D. in Physics from the University of California, San Diego, and conducted postdoctoral work at the University of Texas at Austin.  At MIT, he serves as Director of the MIT Materials Research Science and Engineering Center (MRSEC) and Co-Director of the MIT Materials Research Laboratory, an Institute-wide organization coordinating materials research efforts across MIT.  He also helped develop and launch the New Engineering Education Transformation within the School of Engineering at MIT, a cross-departmental, project-centric approach to education aimed to prepare students for the “new machines” that engineers will build mid-century and beyond.  He has published >85 peer-reviewed papers and delivered >100 invited and plenary talks internationally.  In 2018 he was elected Vice Chair of the American Physical Society Topical Group on Magnetism and its Applications (GMAG). His research group at MIT focuses on the design and understanding of advanced magnetic materials for spin-based memory, logic, and emerging applications. These efforts center on understanding and exploiting interfacial phenomena that provide new mechanisms with which to electrically control magnetism in nanoscale devices.
