In his doctoral thesis he dealt with nonlinear differential equations .

He went to Italy with Jacobi in 1843/1844 and then spent several years doing independent mathematical studies in Berlin. In the winter of 1846/1847 he lived in Paris and completed his habilitation in 1848 at the Friedrich-Wilhelms University of Berlin . In 1856 he became a full member of the Academy of Sciences in Berlin and then took over the continuation of Crelle's Journal for pure and applied mathematics . In 1865 Borchardt married Rosa Oppenheim (* 1843), daughter of the farmer and owner of the "Rittergut Rüdersdorf" Adolph Oppenheim , from the Oppenheim family .
