Research
Summary:
Professor Sridhar's principal areas of research are Nanomaterials and Nanomedicine and Left-Handed Metamaterials.
Nanomaterials
and Nanomedicine: Prof. Sridhar is Director of
the Electronic Materials
Research Institute, an interdisciplinary institute
formed to catalyze and synergize the University’s
research in nanomaterials. He also directs the Nanomedicine
consortium, a collaboration between faculty from several
departments and area medical research hospitals researching
applications of nanotechnology to medical problems including
diagnosis and therapy of cancer, infectious and cardiovascular
diseases. Ongoing projects include functionalized nanoparticles,
energy, drug and gene delivery using nanoparticles, electromagnetic
hyperthermia, and magnetic nanoparticles as MRI contrast
agents. Prof. Sridhar is the director of the IGERT Nanomedicine Science and Technology program (see www.igert.neu.edu).
Left-Handed
Metamaterials: Artificial materials with negative
refractive index are called left handed materials because
of the unusual electromagnetic wave propagation in them.
We have several significant results on negative refraction
and imaging. Our paper in Nature (2003) on flat lens imaging
was cited as one of the Breakthroughs of 2003 by Science,
and by Physics News 2003 by the American Physical
Society. Our work has received extensive attention
in the scientific community as well as the online and
print popular press.
