Obinna Umeh

Obinna Umeh is a Research Software Engineer at the Faculty of Technology, University of Portsmouth, affiliated with the Institute of Cosmology & Gravitation and Portsmouth AI and Data Science Centre. Their work focuses on cosmology, astrophysics, and relativistic effects, with a particular interest in galaxy clustering, HI intensity mapping, and cosmic distance measurements.

• Key Research Areas: Cosmology, General Relativity, Galaxies, Relativistic Effects, Nonlinear Dynamics
• Recent Activities: Peer-reviewed publications, guest editorship for journals, invited talks at international conferences (e.g., Universidad Autónoma de Madrid, Tensions in Cosmology workshop), and dataset contributions.

Obinna's publications explore topics such as vorticity generation in cosmology, relativistic galaxy bispectrum analysis, and implications of a lumpy universe on cosmic distance metrics. Their work often integrates computational methods with theoretical cosmology to address large-scale structure formation and observational challenges in modern astrophysics.

As a peer reviewer and collaborator, Obinna has worked with researchers like Roy Maartens, Chris Clarkson, and others, contributing to advancements in understanding gravitational lensing, power spectra, and cosmic gravitational entropy.
