DESCRIPTION:Tests of general relativity on cosmological scales are essenti
 al to distinguish GR from other alternative gravity models. One way to ach
 ieve this is by probing the growth of structure down to percent-level\, bu
 t this is challenging. I will show it may be achievable if we combine a ph
 oto-z survey with a spec-z survey over the same (large) area of the sky. T
 he error budget on the growth parameter can be effectively reduced by comb
 ining redshift space distortion with weak gravitational lensing over the s
 ame survey volume. Alternatively\, I will show that voids present in large
 -scale structure may be sensitive probes to certain types of modify gravit
 y. I will also go through some challenges in applying these probes\n\nhttp
