Actively refuse to train with the person. Don't just run the other way when it's time to choose partners. _Actively refuse_. Speak with your dojo mates. Get a commitment from them to do the same.
You can make it less confrontational by saying something like "I'm sorry, my ukemi isn't up to training the way you like to train".
If a substantial number of people refuse to train with the person, it will bring the situation to a head quickly which is best for everyone.
