Emma Johnson

Residential Life Area Director

Hi! My name is Emma Johnson, and I am the Area Director for McCormick. I previously worked in MIT’s Office of Student Conduct for a year, and am excited to move into this new role and become a part of the McCormick community. My office door is (almost) always open – stop by any time to chat, complain, or get candy!

My husband, Jun, lives in McCormick as well. We love movies and TV, board games, and eating good food. Come hang out with us on the roof when the weather is nice!

Ashley and JR

Ashley Brown Raynal and Jean-Raymond (JR) Raynal

2/3 West

Hi! We’re Ashley and Jean-Raymond (JR) Raynal, the GRT’s on 2&3 West. Ashley hails from Pennsylvania, and
came to MIT as an undergrad, while JR grew up on his father’s vineyard in southern France, and earned
his master’s degree in Computer Science at a graduate school in Bordeaux. We met while we were both interning
in South Africa, and now we’re happily married! Currently, Ashley is a graduate student in Course 2 working
on building a miniature NMR spectrometer, and JR is using his superior French education to pursue a career
in robotics.

We love board games, movies, DDR, hiking, and video games. Come visit us in 317 to meet us and our turtle,

4/5 West

Hi hi! I am the GRT for McCormick 4/5 West. I am currently a graduate student in the Earth, Atmospheric,
and Planetary Sciences department (course 12), studying Earth’s climate and climate change. My research
topics have ranged from the tropical atmosphere to the Southern Ocean.

When I am not in the Green building, I can be found running, baking, sleeping, watching cat videos (read
as: procrastinating). I look forward to getting to know all the lovely members of the McCormick community!

Brooke and Hok Hei

Brooke and Hok Hei Tam

6/7 West

Hi! We are Brooke and Hok Hei, the GRTs on 6/7 West. We are both PhD students in Course 10 and we got married
in 2013, right before Brooke moved to Cambridge and started at MIT.

Brooke: Originally from rural Michigan, moving to the city has been a big adjustment, but I’m learning to
love the Boston area. As a ChemE grad student, I am working on developing protein-based assays for detecting
DNA methylation, a modification related to cancer. When I have free time, I’m probably figure skating,
running, playing ultimate Frisbee, or practicing the organ.

Hok Hei: I hail from Hong Kong by way of Toronto and Columbus, Ohio. I’m here to find new ways to improve
vaccines and cure cancer (brain and prostate). In my free time I organize global health events around
MIT and develop medical record systems for refugees. I enjoy traipsing around the world, learning new
things, and building stuff.

We look forward to getting to know you all. Stop by 617 to say hi!

2/3 East

I’m Katherine (or Kat, either’s fine!), the GRT for 2+3 East! I’m a Course 3 (Materials Engineering) PhD student, and I was also an undergrad here at MIT in Course 3, so trust me, I get what you’re going through. My research is in metallic glasses – basically we’re investigating a new way to solidify metals really fast that might allow us to make them really strong. (Please, feel free to ask me more, but be prepared. I LOVE talking about materials science.)

Outside of research, I’m what I consider to be a ‘classic’ nerd – I like reading, comic book super heroes, and dungeons and dragons. Ask me about typical nerd icons (i.e. Harry Potter, Star Wars, etc.) and there’s a pretty good chance I’m a fan and I would be happy to Discuss them with you.

I’m really excited to be a GRT here at McCormick, and I’m sure you all will love it here too.



6/7 East

Hi! I am the GRT for McCormick 6/7 East. I am currently a PhD student in Computer Science. My research interests fall into Human Computer Interaction and Information Retrieval, specifically, making big data accessible to everyone! I enjoy traveling and being outside. For fun, I like hiking, canyoneering, scuba diving and sailing. Mostly, I enjoy the company of my friends, sharing dinners and planning trips together. I’m looking forward to being part of the McCormick community and to getting to know you all!
