Research Interest

My research is focused on directional statistics, a field of statistics where data supports are different than the Euclidean, in particular the hypersphere $$ \mathbb{S}^q:=\{\mathbf{x}\in \mathbb{R}^{q+1}:\|\mathbf{x}\|= 1\}, q\geq 1.$$ My PhD research, advised by Eduardo García-Portugués, aims to develop one- and two-samples tests of uniformity on the hypersphere.
