Brief Biography:

Snober has been passionate about nanotechnology throughout her academic career. She received her Ph.D. degree in 2017 from University of Minnesota, USA. She has been part of Biosensors and Nanotechnology group at the University of Minnesota and worked in various projects ranging from detection of food-borne pathogens to finding solutions for water cleaning using nanotechnology. Her work on developing a nano-selenium sponge for cleaning mercury from water has been highlighted through various media platforms in early 2017.
During her Masters, she used nanoparticles for targeted drug delivery to cancer cells.
She has recently joined Li Lab as a postdoctoral fellow. She is excited to learn new techniques and apply nanotechnology to make DNAzyme based detection systems.

Research Interests:

Nanotechnology based homogeneous assays for detection of pathogens and environmental contaminants. Other research interests include using 1. nanotechnology for environmental remediation. 2. Understanding Nature’s nanotechnology at molecular level to develop bio-inspired systems.
