Meet The TCC Council



Aria Eppinger

Hi hi! I'm Aria, and I'm a sophomore from Pittsburgh majoring in Course 6-7 (Computer Science and Molecular Biology). When not psetting, I'm most likely cooking, eating, or swimming (I'm on the MIT Varsity Swim & Dive team -- Go Distance Group!). I am so grateful to the TCC for welcoming me into the MIT community, supporting me through my transition to college, and helping me grow in my faith. I am excited to welcome new first years and pre-frosh (newly admitted/committed students) to the TCC community! Feel free to reach out and say hi!



Carlo Duffy

Welcome, I'm a PhD student at the Institute for Data, Systems and Society. I previously did my undergraduate studies at Carnegie Mellon, where I became closely involved with the Catholic Newman Club. As a native of the Philadelphia region, I continue to root for the Phillies, Eagles and 76ers. I also enjoy playing squash and tennis, as well as participating in the TCC spaghetti suppers and grad men's bible studies. I encourage anyone, especially grad students, who wants to learn more about TCC to reach out to me!



Diane Heinle

Hello there! I’m Diane, from the small town of Hamilton, VA. I’m a junior studying mechanical engineering with electrical engineering and computer science (Course 2A/6). The TCC has been an incredibly welcoming community where I’ve made great friends, and I’m excited to serve it as secretary. I spend most of my free time at MIT with TCC events (spags!), robotics team, and archery club. I also love reading, visiting national parks, and designing 3D printed models.



Marisa Hoosen

Hello! I'm a '23 Course 6-2 from East Peoria, IL and I live in McCormick Hall. As webmaster, I keep the website up to date and send out weekly bulletins to members. Besides the TCC, I'm involved with the MIT Robotics Team, Cru, Society of Hispanic Professional Engineers, and Vice President of the MIT Pro-Life Club. In my spare time, I enjoy crocheting and spending time with my friends.

Prayer Chair

Annastina Taboada

Hello everyone! I am Annastina, a freshman from San Antonio, TX. I am planning to major in 6-2 (Electrical Engineering and Computer Science). TCC is an amazing community which has given me amazing opportunities to meet new friends who share in my faith. As a part of TCC, I am a prayer chair, so I help organize weekly rosaries. Apart from TCC, I am also a member of MIT Motorsports and Society of Hispanic Professional Engineers. In my spare time, I like to watch and talk about sports, read, go on bike rides, and play board games.

Mark Mosser

Hi! My name is Mark Mosser, and I am a 2024 and majoring in course 2. I am from Lakeville, Minnesota. I am very excited to help TCC members be the hands and feet of Jesus as social committee chair. Outside of the TCC, I compete for the men’s track team as a pole vaulter and am a member of MIT’s Army ROTC Battalion.


Social Committee and Spags Chair

Kathryn Linz

Hi everyone! My name is Kathryn, though I also go by Kathy—feel free to call me whichever comes to mind first! I’m on the TCC Social Committee, and I’m also Spags Chair (I plan and cook for the TCC’s spaghetti suppers every Friday night). I’m from the class of 2023 double majoring in 14-2 (mathematical economics) and 15-2 (business analytics), and I live in East Campus on 3rd West, Floorpi. I grew up in Arvada, Colorado, riding horses and driving chariots through an organization called Westernaires, helping out with my church’s confirmation class, attending Latin Mass, and being super involved in my school’s student government. At MIT, most of my free time goes to TCC events and participating in my hall’s various activities and culture.

Kevin Greenman

Hi! I'm a graduate student in the Chemical Engineering and Computation program, studying molecular design and discovery using machine learning and computational chemistry. I grew up in Battle Creek, MI (the "Breakfast Capital of the World"). After graduating from high school, I moved to the other side of the state to attend the University of Michigan in Ann Arbor. I was active in several aspects of my undergrad Catholic community, including alternative spring breaks and organizing a weekly dinner/speaker series.
