Takserman-Krozer worked on diverse aspects of theoretical physics ranging from theory of relativity to studies of polymers and their flow. Her scientific work includes contributions to behaviour of polymers and polymers solutions in velocity fields, theory of spinnability, problems of phenomenological rheology, and molecular-statistical theory of polymer networks.
