He studied at the University of Leiden and the University of Leipzig , where in 1779, after defending his dissertation "De Raris" , he received a bachelor 's degree in medicine and a doctor of philosophy . After he was awarded the degree of Doctor of Medicine at the University of Leipzig on August 25, 1782, he left for Russia .
Arriving in St. Petersburg on December 19, 1782, he passed the exam at the Medical College and received the right to medical practice in Russia. Having entered the Russian service as a divisional doctor of the second division, he went to the Crimea with the troops of Prince Potemkin . In 1784 he was sent to the army of Count Rumyantsev , and on his return from there on December 21, 1786 he was appointed professor of chemistry and botany at the Moscow Medical School . After some time, Stefan suggested arranging the Pharmacy Garden behind the Sukharev Tower, which was in a deplorable state and cultivating “medical plants” in it for the training of physicians and pharmacists. The medical board agreed with this proposal, and on February 14, 1796, the garden and the former laboratory were transferred to his full disposal, leaving only general supervision of the medical office. In a short time, Stefan put the garden in order and organized a museum of natural history with it, which he presented with herbarium from 1800 species of plants, as well as a collection of minerals and insects.
In 1796, at the request of Professor I. D. Giltebrandt , Stefan took as his adjunct his nephew F. A. Giltebrandt , who worked in this position for the next five years  .
In 1804, Stefan left Moscow. Before leaving Moscow, he visited Leipzig , where after passing the exams he received the title of Doctor of Law. In 1804, he became professor of botany at the St. Petersburg Medical and Surgical Academy . At the same time, he was appointed director of the Botanical Garden on Aptekarsky Island .
In 1808 he retired; since 1809, he was under the chief director of state forests “for assignments different in the forest part” and was engaged in arranging Count Orlov’s Forest Institute on Elagin Island . In 1811, he was appointed director of the newly established Practical Forest Institute and held this position until the end of his life.
Throughout his life, Stefan diligently studied the flora of Russia, one of the first to study the vegetation of the environs of Moscow; He studied a lot of plant taxonomy , thanks to which he gained considerable fame. He collected three huge herbaria . One of which was in the Royal Museum of Berlin and was used by Wildenov when working on his work Species plantarum . Another herbarium remained in Moscow. The third, after the death of the owner, together with part of the library was acquired by the Imperial Botanical Garden in St. Petersburg, the herbarium was acquired in two stages: first 1749, later another 2560 sheets. Later, in 1824, his heirs sold another collection and another part of the library to the St. Petersburg herbarium.
