Mi línea principal de investigación son los pulsares. Usamos datos tomados con radio telescopios o satélites de rayos-X para estudiar cómo rotan y qué procesos físicos alteran su rotación. De esta manera aprendemos sobre lo que ocurre dentro y fuera de los pulsares. 

Desde hace poco he estado también trabajando en Física espacial. En particular, hemos estado usado datos tomados en la magnetósfera terrestre para estudiar cómo se distribuye la eneregía entre las partículas y los efectos de la turbulencia en el transporte de energía en la cola de la magnetósfera.
