Welcome!

I am a Member of Technical Staff at Cohere (https://cohere.ai/) specializing in multilingual natural language processing.

Previously, I completed my PhD in Computer Science at the Center for Language and Speech Processing at Johns Hopkins University, where I was advised by Dr. Philipp Koehn. My research is focused on unsupervised and semi-supervised machine translation, bilingual lexicon induction, multilingual representation learning, and efficient natural language processing. During my time at JHU, I interned with Meta AI London (FAIR Labs, Summer 2022, Advisor: Mikel Artetxe) and Google Translate (Summer 2020).

Prior to JHU, I completed an MPhil in Advanced Computer Science at Christ’s College, University of Cambridge. My thesis advisor was Helen Yannakoudakis. I was employed at Google, Inc. in Mountain View, CA from 2013-2017 where I was a Web Solutions Engineer (2015-2017) and Support Specialist for gTech Ads, where I led automation efforts for North America (2013-2015). Previously, I completed an Ed.M. in Mind, Brain, and Education at Harvard University, and a B.A. in Psychology/Sociology and French (minor) at Franklin & Marshall College in Lancaster, PA.

More about me

In my non-CS life, I’m a classically-trained soprano and was a Choral Scholar at Christ’s College, Cambridge. I’ve had fun singing acappella through the years – with Google MTV’s Googapella (2014-2017), the Common Chords at the Harvard Graduate School of Education, and Sweet Ophelia at Franklin & Marshall College.

Apart from singing, I enjoy vegetable gardening – and if “trying new foods” can be considered a hobby, then it’s certainly one of favorites!
