Graduating in 1913 with a thesis on anomalous rotatory dispersion he stayed on at the department of inorganic chemistry and studied under Lev Chugaev.
He also examined complex metal chemistry and synthesized four forms of ammonium derivatives with trivalent rhodium.
He developed a method for the extraction of thee metals from copper-nickel sludge, for which he received the Stalin Prize in 1946.
He worked on rhodium extraction and purification and the synthesis of complex compounds of rhenium and ethylene diamine.
