Postdoctoral Associates

Shuo ChengDr. Shuo Cheng
Dr. Shuo Cheng received his PhD and MS in electrical and computer engineering from the University of Florida in 2011 and 2009, respectively, working with Prof. David P. Arnold. He received his BE in automation from Beijing Institute of Technology, China in 2006. His doctoral research focused on electromechanical transducers for power electronic applications. His dissertation topic was on the theory, design and application of electrodynamic transformers, a new type of power electronic device that transfers electrical energy between isolated circuits using electrodynamically coupled mechanical motion. After receiving his PhD, Dr. Cheng continued working as a Postdoctoral Research Associate for Prof. Arnold, doing research on micromagnetic undulator arrays for X-ray systems. Dr. Cheng joined Velasquez-Garcia’s group as a Postdoctoral Associate in September 2012. His current research is focused on microfabricated silicon-tip field emission cathodes for compact X-ray sources.
Arash FomaniDr. Arash Fomani
Arash A. Fomani received the B.Sc. degree (with honors) in electrical engineering from the University of Tehran, Tehran, Iran, in 2002, and the M.Sc. and Ph.D. degrees in electrical engineering from the University of Waterloo, Waterloo, ON, Canada, in 2005 and 2011, respectively. He was an undergraduate researcher at the Thin Film Laboratory, University of Tehran, where he worked on plasma display panels and crystallization of amorphous silicon and germanium alloys. From 2003 to 2006, he worked in the Giga-to-Nanoelectronics Laboratory, University of Waterloo, modeling the stress-induced instability phenomenon in thin-film transistors. For his Ph.D. studies, Arash joined Centre for Integrated RF Engineering, University of Waterloo, where he developed MEMS switch matrices for RF applications and MEMS microprobes for neural stimulation and recording. Arash joined the Microsystems Technology Laboratories at the Massachusetts Institute of Technology in 2012, where he is working on high performance field emission and field ionization devices for portable analytical instruments.
Frances HillDr. Frances A. Hill
Dr. Frances Hill received her Ph.D. in Mechanical Engineering from the Massachusetts Institute of Technology in 2011, working with advisor Professor Carol Livermore. She received a Master of Science degree from MIT in Mechanical Engineering in 2008 and a Bachelor of Applied Science degree from the University of Waterloo in Systems Design Engineering in 2006. Her Ph.D. research focused on studying the mechanical properties and energy storage capabilities of mechanical springs made of carbon nanotubes. Frances joined the Velasquez-Garcia Group as a Postdoctoral Associate in September 2011. Her current research involves developing MEMS-based electrospray emitters and NEMS cathodes for X-Ray generation.
Michael SwanwickDr. Michael Swanwick
Dr. Michael Swanwick graduated from Cambridge University (UK) in 2011 with a PhD in Electrical Engineering under the supervision of Dr. Andrew Flewitt (Cambridge) and Prof. Tayo Akinwande (MIT). Michael was a visiting student at MIT from 2009 to 2011 working with Prof. Akinwande on zinc oxide (ZnO) nanowire research. The research focused on the piezoresistance of ZnO nanowires and using the nanowires as a visible blind near-UV sensor. Dr. Swanwick graduated with highest honors in Mechanical Engineering from Northeastern University with undergraduate research in ebeam lithography and carbon nanotubes. From Northeastern, Michael went on to get a masters in Material Science from Cambridge. His Master’s research under Dr. Flewitt explored droplet based microfluidics using ZnO thin films and lithium niobate. His current work as a post-doc in the Velaquez group focuses on three projects: 1) Highly ordered vertical CNT growth with sub 100nm packing for ultracapacitors. 2) High current field emission devices with self-aligned extractor. 3) Photo-assisted field emission from nanostructured silicon cathodes.
