In 1895, Samoilov moved to Moscow and began working at Moscow University under the direction of V.I. Vernadsky. In 1902, he defended his thesis for a master's degree in mineralogy and geology “Materials for Barite Crystallography” and was invited to lead the Department of Mineralogy and Geology at the New Alexandrian Agricultural Institute.
