  Ly-alpha emission is indicative of on-going star formation in a dust-poor
environment. Ly-alpha imaging is therefore a probe of the star formation rate
and of the dust-content of Gamma-Ray Burst host galaxies. Both of these
parameters are central to our understanding of GRB progenitors and of how the
environments affect the propagation of afterglow emission out of host galaxies.
We have started a program aimed at imaging high redshift (z>2) host galaxies of
GRBs at the Ly-alpha resonance line from neutral hydrogen. Here were report the
results from imaging of the fields of GRB 000301C and GRB 000926 and outline
upcoming observations of further hosts.
