His primary scientific interests are in Theoretical physics, Orientifold, Particle physics, String theory and Supersymmetry. The concepts of his Theoretical physics study are interwoven with issues in Moduli and Moduli space. As a member of one scientific family, Ralph Blumenhagen mostly works in the field of Orientifold, focusing on D-brane and, on occasion, Gauge group and Standard Model.

His studies in String theory integrate themes in fields like Calabi–Yau manifold and Conformal field theory. His work in Supersymmetry covers topics such as Instanton which are related to areas like Superpotential, Ansatz, Gaugino, D-term and Brane. His study in String is interdisciplinary in nature, drawing from both Noncommutative geometry, Gravitation and Gauge theory.

- TOWARD REALISTIC INTERSECTING D-BRANE MODELS (569 citations)
- Loop-corrected compactifications of the heterotic string with line bundles (225 citations)

The scientist’s investigation covers issues in Theoretical physics, Heterotic string theory, Mathematical physics, String theory and String. His research in Theoretical physics is mostly concerned with Orientifold. Ralph Blumenhagen interconnects Cohomology, Vector bundle, Abelian group, Pure mathematics and String duality in the investigation of issues within Heterotic string theory.

In his study, which falls under the umbrella issue of Mathematical physics, Conformal symmetry and Quantum mechanics is strongly linked to Conformal field theory. His String theory research is multidisciplinary, incorporating elements of Noncommutative geometry, Superstring theory, Calabi–Yau manifold and Gauge theory. His String study also includes fields such as
