个人简介
David Gracias, a Professor of chemical and biomolecular engineering is known for the design, development, and characterization of miniaturized devices, intelligent materials, and systems. Many of these devices and systems are far smaller than what can be visualized with the naked eye or even optical microscopes, which makes them especially challenging to assemble and characterize.
Gracias’s multi-disciplinary approach leverages conventional microelectronic chip fabrication approaches as well as novel self-assembly processes. His laboratory is also known for utilizing elements from both the biotic (bacteria, cells) and abiotic (optical, electronic) worlds to create bionic structures. The laboratory utilizes state of the art fluorescence, FT-IR, Raman, and sum-frequency generation optical spectroscopy techniques; electron microscopy; 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 statistical and analytical methods to model data as well as finite element methods (HFSS, Surface Evolver, COMSOL).
Gracias’s unique training in basic sciences, including physical chemistry and chemical biology, as well as in state-of-the-art engineering R&D in the microelectronics industry, allowed him to break down traditional boundaries by making critical connections between seemingly disparate fields and between basic science and applied research. At Johns Hopkins, Gracias has made revolutionary contributions to biomedical engineering by collaborating extensively with clinicians to apply the capabilities of micro and nanotechnology to modern medicine. In addition to publishing his academic work in top journals such as Science, Gracias is a prolific inventor with 33 issued patents, many of which are commercialized.
