Finally he was appointed lecturer of mathematics and physics in Leiden on May 13, 1822 by royal decree, with a teaching position for astronomy.

After he had published his Specimen Geographico-Historicum exhebens Dissertationem de Ibn Haakalo Geographo, nec non Descriptionem Iraeae Persicae, cum ex eo Scriptore tum ex aliis Mss. Arabicis Bibl. LB petitam (Leiden 1822) on June 14, 1822 , he was appointed Doctor of Philosophy and he took up his teaching post on November 2, 1822 with the Rede de Astronomiae conditione apud Arabes, aliasque medii aevi Gentes Orientales . In 1826 he was appointed associate professor of mathematics and physics, with the teaching assignment for astronomy and natural history, which office he took on September 30, 1826 with the speech de hodierni physices, astronomiaeque stadii praestantia .

Regia. published. On September 7, 1835, he was finally appointed full professor of mathematics and physics, with a teaching position for astronomy and natural history, which also made him head of the Leiden observatory .

In his capacity as a university lecturer in Leiden, he also took part in the organizational tasks of the educational institution.

In 1838 he participated as a member of a Dutch commission in Paris, where, for example, the Dutch pound and the Dutch yardstick were unified.
