At Aims-Cameroon for his structured masters essay, Theophile presented the Newton transformation of the operator form on the screen distribution of a normalized lightlike hypersurface. Using this Newton transformation, he derived some integral formulae for normalized lightlike hypersurfaces.
After his structural masters, he pursued postgraduate studies at the Institute of Mathematics and Physical sciences where he completed in 2021 a PhD’s degree in Mathematics in which he investigated ”Null hypersurfaces in a spacetimes with certain symmetries” under the supervision of Professor Cyriaque Atindogbe.´
