Current Research work:
NUCLEI-PACK: — a framework I have been developing to explore nuclear structure from a purely geometric and semi-classical perspective. The approach is based on optimized sphere packing of nucleons and clusters, where explicit spatial coordinates are assigned to each proton and neutron. This representation captures the effect of the short-range nuclear force, in which strong repulsion prevents nucleons from overlapping, effectively treating them as hard spheres at close distances.
Recent studies within this project include:
H.M. Maridi, “Cluster and Halo Structures of Light Nuclei within the NUCLEI-PACK Framework”, Arxiv: 2510.10741 (2025)
H.M. Maridi, “Global Trends of Nuclear Radii and Binding Energies from the NUCLEI-PACK Framework”, Arxiv: 2509.13750 (2025).
The project reproduces the global trends of nuclear radii and binding energies and provides a unified geometric interpretation of clustering and halo formation in light and exotic nuclei.

My future research plans are:
Developing model of calculation for the Coulomb breakup for exotic projectiles. Including three-body formalism, core excitation, target excitation, transition between two bound states, calculating the dipole response functions, using new wave functions for the bound states, ...
Getting a global microscopic nucleon-nucleus and nucleus-nucleus optical potentials can describe well the real interaction between the nucleons and be used to analyze the nuclear reactions over a possible wider range of energy; predict the basic scattering observables for energies and nuclei for which no measurements exist; and reproduce fusion, Coulomb breakup, nuclear breakup, elastic scattering cross sections correctly at the same time.
My research was completely stopped in:
March 2015 to September 2018: because of the war and conflict in my country, Yemen. My story is featured in Nature 598, 527 ( 2021) and many websites.
September 2009 to the end of 2011: because of looking for jobs in 2009-2010 and arising the Arab Spring revolutions in the 2011.
