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. Anna Lauren Hoffmann.

I use mixed methods on social media data and trace 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.

My pronouns are he/him.

Projects.

Gender in Online Networks
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, and examine how different cultures construct their own ideas of gender.
Gender and Quantification
This project focuses on how transgender and non-binary identities are encoded in data. It is just starting!
Propaganda, Framing, and Race
​This was a multi-year project with Dr. Starbird's emCOMP lab studying #BlackLivesMatter and #BlueLivesMatter discourse on Twitter. Our work focused on the framing processes associated with the two hashtags and their vulnerabilities to disinformation campaigns.

Before reading any of our stuff, please take 15 minutes to research police and prison abolition efforts in your area.
Critical Quantitative Methods
I facilitate a weekly reading group that discusses the potential for critical perspectives in quantitative work. We read current work from a variety of domains, including data science, science and technology studies, knowledge organization, and critical data studies.

Background.


#⃣️
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.
