Professor Gracias focuses on developing new methods of fabricating nanoscale devices, including 3D devices that self-assemble, and has been named the Russell Craft Scholar. He earned his MS (’94) at the Indian Institute of Technology and his Ph.D. (’99) at the University of California at Berkeley. He did post-doctoral work at Harvard University from 1999-2001.
The Gracias Lab develops new methods to fabricate very small devices and integrated structures, and characterizes these systems using microscopy and spectroscopy. A major thrust of their research is focused on 3D devices which are especially challenging to fabricate at small size scales because of the inherent two dimensionality of lithographic processes. The laboratory is multidisciplinary and students utilize a range of experimental techniques including photo-, e-beam and nano-imprint lithography; thin film disposition, molding, etching, culture of prokaryotic (E Coli) and eukaryotic (e.g. fibroblasts, insulinoma, cardio myocytes) cells, biological assays (e.g. fluorescent stains, ELISA), non-linear optical spectroscopy, electron microscopy (TEM & SEM with fixation), RF measurements such as GHz spectrum analysis, electrochemical methods such as potentiometry and chronoamperometry and four point electrical testing with femto-amp resolution. Students also utilize analytical methods to model data as well as finite element methods (HFSS, Surface Evolver).
