Current Research Interest  

1. Study of the p-groups in which the intersection of any two nonincident subgroups is abelian.
2. Classifying the p-groups all of whose nonnormal subgroups are; Abelian, modular.
3. Classifying the 2-groups with 11 involutions.
4. (Blackburn) Classifying the p-groups G, p > 2, d(G) = 2, all of whose maximal subgroups are two-generator.
