One cannot claim impose a simplistic division of what is “Greek” or “Roman” one a historical period in which such identifications were becoming increasingly less important. Andronikos of Kyrrhestes, Hero of Alexandrēia, Claudius Ptolemaeus, Diophantus, Pappus of Alexandrēia, and Hypatía of Alexandrēia were all inhabitants of the Greek-speaking eastern half of the Roman Empire, but to claim that there were no “Roman” scientists, only “Greek” ones essentially ignores the fact that all Greek scientists in the imperial period were either socii under the imperium of the Roman imperial state, or, after the Constitutio Antoniniana of A.D. 212, full Roman citizens.
