Vincent's research bridges biochemical and synthetic inorganic methods to study metallobiomolecules. Notable work includes elucidating the role of chromium in insulin signaling through the chromodulin complex, developing synthetic biomimetics like Cr3 for cholesterol regulation, and innovating metalloprotein affinity metal chromatography for actinide removal. His methodologies span chromatography, spectroscopy (electronic, Raman, ESR, NMR), and mass spectrometry.

Recent publications highlight chromium's interactions with DNA, mechanistic studies of chromium(III) in electrospray ionization, and structural analysis of chromium-transferrin complexes. Research trends emphasize chromium's physiological relevance, biomimetic design, and environmental applications of metal-binding proteins.

Vincent's laboratory investigates chromium's role in diabetes management, the biophysical properties of metalloproteins, and sustainable metal recovery techniques. Collaborative projects span nutritional biochemistry, toxicology, and materials science.
