Croke-Kleiner admissible groups firstly introduced by Croke-Kleiner belong to a particular class of graph of groups which generalize fundamental groups of 3-dimensional graph manifolds. In this talk, we will present a characterization of strongly quasiconvex subgroups by the finiteness of height. With further assumption on the vertex groups, we show that a CKA group satisfies a property (QT) introduced by Bestvina-Bromberg-Fujiwara that the group admits an equivariant quasi-isometric embedding into a finite product of quasi-trees. This is a joint work with Hoang Nguyen.
