After 2 years of the medical practice in Karelia he entered (1957) position of a senior research assistant at the I.M. Sechenov Institute of Evolutionary Physiology (Now IEPhB RAS) where he continues to work as a chief researcher. In 1960 he defended his Ph.D. thesis, and in 1970 - his doctoral thesis. For more than 40 years he chaired the Laboratory of the Biophysics of Synaptic Processes. Since 1996 holds a position of a tenured professor at the Department of Physiology of Medical Faculty of Saint-Petersburg State University. In 1997 Lev Girshevich was elected associate member, and in 2016 - full member of the RAS.
