In this summary, I expose my work on the Degree/Diameter and Cage Problems for bipartite biregular graphs. This review is the second part of another one published previously in [G. Araujo-Pardo, Contributions on the Cage and Diameter Problems. Advances in the Mathematical Sciences - AWM Research Symposium, Minneapolis, MN, June 2022. Springer Nature (2024)], where I provided a detailed analysis of my contributions in the original case of these problems, which are regular and biregular graphs in one of their early generalizations. As in the previous work, I finish this summary by giving a brief list of topics I have worked on in the last six years.
