I connect gravitational theory with astronomical observations to investigate dark energy, dark matter and the growth of cosmic structure. My work spans modified gravity, interacting dark-sector models, cosmological perturbations and black-hole physics.
Can one cosmological model explain cosmic expansion, the strength of matter clustering and the distinctive predictions of its underlying physics? The Cosmological Consistency Triangle brings these tests together in a framework for comparing models.

Cosmological Tensions as Consistency Conditions for f(Q) Gravity
Published conference proceedings · PoS(CORFU2025) 219 (2026) · DOI
New preprints address conformally interacting dark energy, gravitational waves in shear-free cosmologies and curvature in f(Q) gravity, alongside work on astronomy knowledge in Africa and an Africa-wide ISS radio-contact experiment.
