DESCRIPTION:The structure of debris disks carries an abundance of informat
 ion\, such as on the presence of embedded bodies and the dynamical history
  of the planetary system. Edge-on debris disks offer a unique opportunity 
 to simultaneously access the radial and vertical distribution of material\
 , however recovering either distribution in an unbiased way is challenging
 . In this talk\, I present a non-parametric method to recover the face-on 
 surface brightness profile and height profile given an observation of an a
 zimuthally symmetric\, edge-on debris disk. Compared to parametric approac
 hes\, this method not only avoids biasing the fitted profiles towards an a
 ssumed functional form\, but also provides more realistic uncertainties on
  the underlying model. I also present results from applying the algorithm 
 to ALMA and mid-infrared observations\, comparing our results with those f
 rom parametric studies for each example and discussing the implications of
  the new structural information.
