What do CAs do?

Community Associates (CAs) are graduate students who enjoy being involved with the Rains community. Their goal is to help build a sense of community among Rains residents. CAs:

  • Plan educational, cultural, social, and recreational programs at the neighborhood and Rains-wide levels.

  • Offer information and advice to anyone who needs help finding services or information on Stanford Campus.

  • Create opportunities for residents to take an active role in the organization of events.

Each building in Rains is part of a neighborhood served by at least two CAs. We have a lot of information about Stanford and the surrounding communities. We're available when you have specific questions and when you just want to talk.

Sabrina Papazian

A big WELCOME to Rains! My name is Sabrina, and I’m excited to be one of your Head CAs this year. I’ve just returned to Rains after an exciting year abroad in Armenia, where I was doing fieldwork for my dissertation. I’m a 5 th -year PhD candidate in Anthropology, where I study the management and reconstruction of cultural heritage in Armenia, which includes some amazing medieval churches and prehistoric caves! I was born and raised in the Washington, D.C. area, did my undergraduate at Cornell, and spent a lovely year at Cambridge completing an MPhil. If you don’t find me hanging out in Rains, I’m usually doing an awesome T-rex impersonation, initiating impromptu dance parties, or finding new and exciting workspaces. Once again, welcome, and don’t hesitate to reach out! I’m excited to be back in the neighborhood

Peyton Greenside

Hey everyone! My name is Peyton, and I'll be one of your CAs in Midtown. I'm a fourth year PhD student in Biomedical Informatics, which means I spend my time analyzing genomes to understand how disease arises. I grew up in North Carolina and then moved north and did my undergrad at Harvard in applied math. I also spent a year drinking tea and eating scones in England and a year working at a genomics research institute before coming to Stanford. Now I spend all of my free time going hiking, playing sports, and finding ways to travel to exciting places. Let me know if you have any fun ideas for events, and I look forward to getting to know you all this year!

Rebecca Marton

Hi everyone! My name is Rebecca, and I’m originally from the Greater Boston area. I went to undergrad at the University of Notre Dame where I majored in Biological Sciences and going to football games. I’ve been a CA for the Frontier for the past couple years, but this year I’ll be acting as the treasurer of Rains. I’m currently a 4 th year PhD student in Stem Cell Biology and Regenerative Medicine. Outside of the lab I enjoy cooking, hiking, and traveling.

Michael Dubreuil

Well hey there you! I'm Mike and I am a CA for the Plains of Rains! I am in my fourth year of my PhD in Cancer Biology in the School of Medicine. I grew up in the great state of New Hampshire. When I'm not studying oxidative stress in the lab, I like getting outdoors, listening to alternative rock, adventuring in San Francisco, traveling to new places, consuming edible things, as well as a number of other eclectic activities. I'm super excited to continue being your CA this year and would love to hear from you if you have any questions/comments/concerns/conundrums/compliments so don't hesitate to shoot me an email or talk to me in person!

Fabian Frank

Welcome to Rains! My name is Fabian and I have the pleasure of living in Rains for my second year now. In the first year I got to know all the amazing people living here through fun events put together by the CAs of Rains. It is really a great way of meeting people and finding friends in your neighborhood. This year, I switch sides and will be helping you make these connections and hopefully we will have a lot of fun together. Originally I am from Germany, where I spend most of my life (besides 3-6 months stays in Spain, England and New Zealand) and moved to the US last year for my Master’s in Management Science and Engineering. I am a pretty active person and would love to play volleyball or any other sport with you. I am also always up for exploring the area, so count me in on any weekend trips. I am really looking forward to meet you all!

Shalini Ranmuthu

Hello there! My name is Shalini, and I'm a second year master's student in Electrical Engineering. I grew up in Texas and did my undergrad in Biomedical Engineering at UT Austin (HOOK 'EM), and I firmly believe that "y'all" is the best and most efficient way to address a group of people. I enjoy all things music-related (listening, jamming, buying cheap instruments on a whim, the Stanford Band, etc.) to the extent that you should probably remind me to go study every now and then (or join in!). I'm also fond of hammocking, eating cheesecake, frisbeeing, playing board games, and hiking. Hit me up if you want to talk about anything or everything, and I can't wait to see all your lovely faces around Rains!

Anton Jackson-Smith

Hi! I’m Anton, a third-year bioengineering PhD student from New Zealand. I’m working on the platform to make the engineering of living matter more reliable, predictable, and accessible, by building the world’s first synthetic cell: I’m also interested in the intersections between new technology, ethics, philosophy and law, and how new technology can serve to enfranchise and empower people across the world. I’m an Orchard CA this year: you can recognise me by either my dreadlocks, or the weird red trike occasionally covered in lights and speakers. I also love cooking, skiing, and backpacking/mountaineering, so come and talk to me about those things, or anything else. Nice to meet you!
