Since 2003 she has been Chief Research Fellow of the Department of Plant Reproduction. In 1962 she received a PhD degree in Biology; in 1973 a degree of the Doctor of Biological Sciences; and in 1991 the scientific title of Professor.
In 1998 Guranda Gvaladze was elected as Academician of the Abkhazian Regional Academy of Sciences (based in Tbilisi).
In 1990 she received the International S. Navashin Medal "For outstanding contribution in Plant Embryology". She is listed in the Encyclopedic work "Embryology of Flowering Plants: Terminology and Concepts" (in 3 volumes, St.Petersburg, 1994-2000) as a Classic of Plant Embryology. Gvaladze is a member of: the International Association of Sexual Plant Reproduction Research/IASPRR (The Netherlands), the International Organization of Plant Information/IOPI (U.S.), the European Association on Promotion of Science and Technologies/EUROSCIENCE (France), the Scientific Council of the Georgian Botanical Society (Tbilisi).
Guranda Gvaladze's main fields of scientific activity are: Double Fertilization of Angiosperms and other important questions of Plant Embryology, Plant Cytology and Apomixis, etc. She is the author of the well-known hypothesis about the role of the Chalazal Polar Nucleus in the Double Fertilization and Consideration about the biological nature of polarization of the Embryo Sac (1976). She is author of more than 180 scientific-research publications (among them 3 monographs and 1 textbook).
