Research Interests

My research has been focused on understanding the single-particle structure of exotic nuclei. In particular, I have been involved in experiments which have utilized a number of techniques, including gamma-ray and neutron spectroscopy, as well as direct nucleon transfer reactions, to measure properties of light neutron-rich nuclei.
