Ralu Nana Silvia Divan



Ralu Divan is a top micro-nanofabrication expert with 20+ years of experience in materials, process, and device integration. She joint the Center for Nanoscale Materials in 2005 and her current research interest is in the area of development of high resolution, high aspect ratio lithographic processes by development of etching and growth processes for advanced micro- and nano-devices, characterizing chemical and lithographic properties of materials, synthesis of nanoparticles and their use in micro-/nanodevices, characterizing interfacial and compatibility properties of materials used in MEMS and NEMS, and development of membrane-based devices. She has published over 150 papers in journals and conference proceedings, two patents and she is a recipient of a R&D 100 Awards, and a R&D 100 Awards Finalist.
