Hello!

I'm really excited to be pursuing my PhD in Information Science at the University of Washington iSchool in Seattle. I'm part of the DataLab and advised by Dr. Emma Spiro and co-advised by Dr. Kate Starbird.

I use mixed methods on social media data as a lens to study communities, knowledge, and social identities in digital spaces, particularly towards resilient information systems for marginalized groups. My research interests are primarily in synthesizing social network analysis and computational social science with critical theory and science and technology studies.

Projects.

Propaganda, Framing, and Race
​This is a multi-year project with Dr. Starbird's emCOMP lab studying #BlackLivesMatter and #BlueLivesMatter discourse on Twitter.
​Our work focuses on the framing processes associated with the two hashtags and their vulnerabilities to disinformation campaigns.
Gender as Networked Discourse
In this project advised by Dr. Spiro, I've been studying Reddit as a site for networked, crowd-driven discourse centering on gender. 
I use a networks approach to examine trajectories of discourse (such as feminism and "red pill") over time and digital space.
Rumor Permutations and Worldview
My work here is part of a team effort led by Dr. Spiro and Dr. Starbird to study permutations of rumors.
My specific project aims to model worldviews using Twitter trace data as they relate to rumoring.

emCOMP Lab
Research Assistant
Summer 2017 - Summer 2018
I had the chance to work in Dr. Kate Starbird's lab, where I worked with other students to conduct mixed-methods analyses on social media data. I also learned to use Python, SQL, Gephi, REST APIs, and Tableau to collect, analyze, and present data.

​🌡️
Data Analysis @ Institute for Health Metrics and Evaluation
​Summer 2017 - Summer 2018
I started at IHME as a research intern in Summer 2017 and continued as a data analyst after my internship. I built skills relating to data cleaning, cataloguing, and visualization and quantitative analysis, along with the accompanying infrastructure. I worked with datasets from a variety of sources using R, Python, and SQL. I also gained experience with large-scale, data-driven research and current topics at the intersection of global health and data science, particularly transparency and accuracy in modeling.
