Looking for flatmates/ house share/ buddy up

Hi! I'm moving to London from Chicago for post-graduate study at Imperial College London in bioengineering. I'm looking to move a little before my start date which is in January. I'm hoping to live not too far from campus however I'm open to really anywhere where I can access the central line since I don't really mind a commute. I'm looking for people who are social/as I'm interested in becoming friends with my roommates rather than just living together and I won't really know many people in London since I'm new to the city! I really like going to concerts, exploring the city, and going out to pubs. I also enjoy spending nights in with friends and cooking together. I'm also looking for people who share similar core values and want our space to be welcoming and politically aware. I'm pretty easygoing but and can be extroverted however I do like time to myself as well.
