Dr. Grigoryeva Natalia is currently a senior research fellow at Saint-Petersburg Scientific Research Centre for Ecological Safety of Russian Academy of Sciences, Russia. She is also an official scientific consultant of the Department of Nanoelectronics and the Department of Software Engineering and Computer Applications at Saint-Petersburg Electrotechnical University. In the last six years, she was involved in studying cyanobacteria and developing fluorescence methods for their investigation. She developed an in vivo technique for investigating weak external actions on the physiological state of cyanobacteria. Dr. Grigoryeva recently elaborated on the base of a neural network algorithm an original method of ataxonomic classification of cyanobacteria using single-cell self-fluorescence spectra. Her research interests include both environmental and biotechnological aspects of cyanobacterial applications.
