Narrative:

During landing on runway 9 I encountered wake turbulence which caused me to veer off the runway into the grass. I taxied back onto the nearest taxiway and proceeded to parking. There was no damage to the plane. I should have landed longer to avoid the turbulence from the previous landing aircraft. This was at the end of a long bumpy IFR flight. As a result; I was in a bit of hurry to land; and was not as vigilant regarding wake turbulence avoidance as I normally am.
