DESCRIPTION:James Hwang is a professor in the Department of Materials Scie
 nce and Engineering at Cornell University. He graduated from the same depa
 rtment with a Ph.D. degree. After years of industrial experience at IBM\, 
 Bell Labs\, GE\, and GAIN\, he spent most of his academic career at Lehigh
  University. He cofounded GAIN and QED\; the latter became the public comp
 any IQE. He used to be a Program Officer at the U.S. Air Force Office of S
 cientific Research for GHz-THz Electronics. He had been a visiting profess
 or at Cornell University in the US\, Marche Polytechnic University in Ital
 y\, Nanyang Technological University in Singapore\, National Chiao Tung Un
 iversity in Taiwan\, and Shanghai Jiao Tong University in China. He is an 
 IEEE Life Fellow and a Distinguished Microwave Lecturer. He is also a Trac
 k Editor for the IEEE Transactions on Microwave Theory and Techniques. He 
 has published approximately 400 refereed technical papers and been granted
  eight U.S. patents. He has researched the design\, modeling and character
 ization of optical\, electronic\, and micro-electromechanical devices and 
 circuits. His current research interest includes electromagnetic sensors f
 or individual biological cells\, scanning microwave microscopy\, and two-d
 imensional atomic-layered materials and devices.\nMicrowave is not just fo
 r cooking\, smart cars\, or mobile phones. We can take advantage of the wi
 de electromagnetic spectrum to do wonderful things that are more vital to 
 our lives. For example\, microwave ablation of cancer tumor is already in 
 wide use\, and microwave remote monitoring of vital signs is becoming more
  important as the population ages. This talk will focus on a biomedical us
 e of microwave at the single-cell level. At low power\, microwave can read
 ily penetrate a cell membrane to interrogate what is inside a cell\, witho
 ut cooking it or otherwise hurting it. It is currently the fastest\, most 
 compact\, and least costly way to tell whether a cell is alive or dead. On
  the other hand\, at higher power but lower frequency\, the electromagneti
 c signal can interact strongly with the cell membrane to drill temporary h
 oles of nanometer size. The nanopores allow drugs to diffuse into the cell
  and\, based on the reaction of the cell\, individualized medicine can be 
 developed and drug development can be sped up in general. Conversely\, the
  nanopores allow strands of DNA molecules to be pulled out of the cell wit
 hout killing it\, which can speed up genetic engineering. Lastly\, by chan
 ging both the power and frequency of the signal\, we can have either posit
 ive or negative dielectrophoresis effects\, which we have used to coerce a
  live cell to the examination table of Dr. Microwave\, then usher it out a
 fter examination. These interesting uses of microwave and the resulted fun
 damental knowledge about biological cells will be explored in the talk.\n\
