Environment - Non Weather Related; Human Factors; Procedure
Being vectored on a NON STAR arrival into IAH we were assigned runway 27. ATC was calling out speeds; headings and altitudes; our last speed assigned was 170 to REDOC; cleared for visual approach 27; contact Tower 135.15. When we contacted Tower he informed us to slow because we were overtaking preceding (2.5 miles ahead) aircraft by 20 kts. We configured and slowed to final approach speed flaps 5; approximately 140 kts. On glideslope at that point we were instructed to S-turn south; but before I could do that the aircraft rolled left violently startling myself and the FO. I immediately took action to recover wings level and the autopilot was sounding 'Auto Pilot; Auto Pilot'. I'm not sure if it kicked off or disengaged by my upset recovery inputs. I called out 'TOGA; flaps 2' and we got the aircraft climbing. Cleaned up to flaps 1; stabilized and re-automated. Our only explanation is we believe we encountered wake turbulence from the bigger Airbus ahead. We calmed ourselves and ATC brought us around for a normal approach and landing on runway 27. I would like to add that it was a very hectic day with ATC doing their best to bring all of thunderstorm delayed aircraft [in]; some with minimum fuel.[Suggest] slowing on our own if needed for safety.
