My interests are in at least two areas:
 1] With Chris Johns-Krull, I am interested in the inversion of HXR
spectra
        to obtain electron spectra by our method, and how it compares with
        other methods.
 2] I'm interested in the energy loss and escape of energetic particles,
both
        ions and electrons. I hope there will be sufficient participation
by the
        gamma-ray experts.
