  The goal of this work is to conduct a photometric study of eclipsing binaries
in M31. We apply a modified box-fitting algorithm to search for eclipsing
binary candidates and determine their period. We classify these candidates into
detached, semi-detached, and contact systems using the Fourier decomposition
method. We cross-match the position of our detached candidates with the
photometry from Local Group Survey (Massey et al. 2006) and select 13
candidates brighter than 20.5 magnitude in V. The relative physical parameters
of these detached candidates are further characterized with Detached Eclipsing
Binary Light curve fitter (DEBiL) by Devor (2005). We will followup the
detached eclipsing binaries spectroscopically and determine the distance to
M31.
