The College Preparatory School

Graduated Cum Laude June 2012

I served as Student Council President in 2011-2012 and spent three years prior as class president. I served for two years as captain of the debate team.



Software Engineering Intern June - August 2015

Intern for Google's Ground Truth team, responsible for building the Geo-Data platform that all Google maps and geo-products are built on top of. I used Google's location data to build a map-reduce pipeline that utilizes unsupervised clustering techniques to infer indoor floor plan features. I was the first engineer at Google to explore this new use of data. The results of my project led to new collaborations between various geo-data teams at Google.

UC Berkeley Computer Vision Lab

Research Assistant May - December 2015

Research assistant for Prof. Alexei Efros, working in close collaboration with Shiry Ginosar. I modified MIT’s LabelMe annotation tool to enhance Mechanical Turk annotation compatibility. I created a dataset of 96,000 diverse yearbook photos and ensured a statistically representative distribution of teenagers in the United States. For more information on the paper we wrote, see publications.


Comfort level scored on a scale of low familiarity to high proficiency.

A Century of Portraits: A Visual Historical Record of American High School Yearbooks

S. Ginosar, K. Rakelly, S. Sachs, B. Yin and A. Efros ICCV 2015 Extreme Imaging Workshop

Paper abstract:
Many details about our world are not captured in written records because they are too mundane or too abstract to describe in words. Fortunately, since the invention of the camera, an ever-increasing number of photographs capture much of this otherwise lost information. This plethora of artifacts documenting our "visual culture" is a treasure trove of knowledge as yet untapped by historians. We present a dataset of 37,921 frontal-facing American high school yearbook photos that allow us to use computation to glimpse into the historical visual record too voluminous to be evaluated manually. The collected portraits provide a constant visual frame of reference with varying content. We can therefore use them to consider issues such as a decade's defining style elements, or trends in fashion and social norms over time. We demonstrate that our historical image dataset may be used together with weakly-supervised data-driven techniques to perform scalable historical analysis of large image corpora with minimal human effort, much in the same way that large text corpora together with natural language processing revolutionized historians' workflow. Furthermore, we demonstrate the use of our dataset in dating grayscale portraits using deep learning methods.

Brown CS

Women in Computer Science

Organization Coordinator 2014-2016

I coordinated the departmental group for Brown Women in Computer Science. Representing WICS, I attended faculty meetings and met with Diversity Committee faculty to improve the experience of women and under-represented racial minorities in the department. I also assisted in providing student perspectives on new faculty hires. I coordinated events and mixers for women in our department. I have sat on various panels throughout the university about minorities in STEM and starting CS late. I formerly served as the Mentorship Coordinator, in which I nearly doubled the particpation rate.

Undergraduate TA

Voted "Best of the Best" TAs in Brown Computer Science Spring 2015

Nominated by students and fellow TAs. Awarded during a departmental end-of-year ceremony. One of five recieptients out of over 200 TAs in the department. Sample of nomination text below:

Sarah has been enthusiastic, unconditionally kind, thoughtful, and incredibly motivating to me throughout my time in CS16. While many of the CS16 TAs are excellent, I feel that Sarah has a much better ability than most to understand issues that students face (both academic and otherwise), from the student's perspective. Essentially, I feel her abilities as a TA and qualities as a person do not deserve to go unacknowledged by the department.
Sarah is an absolutely fantastic TA! She brings incredible enthusiasm and kindness that makes her a delight to work with as a fellow TA and an amazing resource for students.

Brown Daily Herald

Staff Writer 2012-2014

My beat was campus planning and faculty accomplishments in Science and Research. New York Magazine featured my work on economics concentrators’ career aspirations in May, 2013. After my time as a writer, I organized and analyzed the biannual “Herald Poll”, which collects public opinion data from the student body.

Brown Political Review

Interviews Board 2013-2014

I interviewed professors and relevant political thinkers on current events. Fox News, Huffington Post, Daily Kos, and International Business Times all featured video coverage I produced of protests on University campus. I also published weekly podcasts of professor interviews.


In a previous life, I was a debater.

In 2012, I was ranked the fourth best high school debater in the nation and the top female Lincoln Douglas debater in the nation. Check out some articles on my accomplishments.
