Dr. Toropova had taken part in the development of an approach to Chemoinformatics modeling based on optimal descriptors. The method based on optimal descriptors can be a useful alternative to traditional QSAR for analysing nanomaterials and drug discovery. She participates in the work of Editorial Boards of scientific journals (as a reviewer and a Guest Editor). Her research interests are QSPR/QSAR, the Monte Carlo method, nanoinformatics, toxicology, nanotoxicology, and drug discovery.
