His scientific interests lie mostly in Atomic physics, Dipole, Wave function, Ground state and Ionization energy. Wilfried Meyer is interested in Configuration interaction, which is a field of Atomic physics. His research investigates the connection between Dipole and topics such as Perturbation that intersect with issues in Quantum electrodynamics and Molecular physics.

Wilfried Meyer works mostly in the field of Ground state, limiting it down to concerns involving Atomic orbital and, occasionally, Adiabatic process, Ion, Ionization and Molecular orbital. His Ionization energy study integrates concerns from other disciplines, such as Valence and Ab initio quantum chemistry methods. His Moment course of study focuses on Bond length and Ab initio, Potential energy and Excited state.

- PNO–CI Studies of electron correlation effects. I. Configuration expansion by means of nonorthogonal orbitals, and application to the ground state and ionized states of methane (845 citations)
- PNO-CI and PNO-CEPA studies of electron correlation effects (542 citations)
- Treatment of intershell correlation effects in ab initio calculations by use of core polarization potentials. Method and application to alkali and alkaline earth atoms (535 citations)

His primary areas of study are Atomic physics, Ab initio, Dipole, Wave function and Ab initio quantum chemistry methods. His Atomic physics study combines topics from a wide range of disciplines, such as Spectral line and Electronic correlation. While the research belongs to areas of Ab initio, Wilfried Meyer spends his time largely on the problem of Absorption spectroscopy, intersecting his research to questions surrounding Absorption.

His Dipole research also works with subjects such as

- Perturbation which is related to area like Atomic units,
- Molecular physics and related Bond-dissociation energy. His Wave function research incorporates elements of Force constant, Hartree–Fock method, Polarizability and Force field. His studies in Configuration interaction integrate themes in fields like Electronic structure, Atomic orbital and Ground state.
