Assistant Professor, Nanoscience



Curriculum Vitae: PDF, March 2018

Dr. Ignatova’s personal research interests and professional training are highly cross-disciplinary, enabling wide perspective on nano-science in general. While the solid physics backgrounds and extensive research experience in nanotechnology and bioengineering allow her to excel at the cutting edge of applied physics and materials science of low-dimensional nanostructures.
In her group, they work on a number of projects on experimental nanoscience of low-dimensional materials, focusing on physics of biosensing, spectroscopic intra-cellular imaging, and nanofabrication for energy storage. This research is aimed on advancing applications based on 2D layered materials and hybrid DNA-nanotube structures, pushing the limits of nanocharacterization and nanofabrication, and exploring nanomaterials for transdisciplinary applications.
In general it is NANO-OPTO-BIO
  1. Physics of low-dimensional materials
