On subgroups of right angled Artin groups with few generators
, 2015 For each natural number $d$ we construct a $3$-generated group $H_d$, which is a subdirect product of free groups, such that the cohomological dimension of $H_d$ is $d$.

Quasi-isometry Invariants from Decorated Trees of Cylinders of Two-Ended JSJ Decompositions [PDF]
, 2016 We construct quasi-isometry invariants of a one-ended finitely presented group by considering the tree of cylinders of a two-ended JSJ decomposition of the group.

Examples of retracts in a free group that are not the fixed subgroup of any group of automorphisms [PDF]
, 2005 Let F be a free group of rank at least three. We show that some retracts of F previously studied by Martino-Ventura are not equal to the fixed subgroup of any group of automorphisms of F. This shows that, in F, there exist subgroups that are equal to the
