About the Council


Mariana Avila


Hi! My name is Mariana, and I’m the TCC president/council chair. I’m a junior from Chicago studying mechanical engineering and living in McCormick Hall. In my free time, I love hanging out with friends, playing piano and dancing. My love for dance and my Venezuelan background led to my involvement in MIT’s DanceTroupe and the Society of Hispanic Professional Engineers. I also help out with a Catholic leadership program for high school girls on the weekends. If there is anything you would like to see in the TCC or something you need help with, please reach out! I’d love to hear from you. :)
