He was a professor at the Saint Petersburg Technological Institute and Saint Petersburg State University in 1864 and 1865, respectively. In 1865 he became Doctor of Science for his dissertation "On the Combinations of Water with Alcohol". After becoming a teacher, he wrote the definitive textbook of his time: Principles of Chemistry.
