Fractional Data Scientist

Professionally, I am a data scientist with skills across a broad range of methodological and engineering competencies - data mining, automation, machine learning, visualization, cloud computing, algorithmic bias, and statistics. Personally, I am a creative mind driven by the opportunity to learn.

I love creative solution-building from messy problem sets and helping organizations get started using data in a more efficient, effective way. I am passionate about streamlining and scaling data pipelines, as well as creating robust equity-first algorithms. I am particularly excited about working with non-profits and small groups led by a mission for social good.

Work

Diversity of Economics Seminar Speakers
- Data Visualization
- R Language
A main way academic economists build networks and share and get feedback on their work is by giving seminars at other departments. Departmental choices about whom to invite to give seminars can therefore shape individuals’ careers and may contribute to or help reduce existing disparities in the profession. I supported building this dashboard, which provides information about who gives invited talks, in aggregate, by department, and for each seminar series within a department.

Consultant for Scaled Risk Models funded by Google.Org
The Student Success Tool is a product funded by Google.org and meant to scale student risk models to hundreds of institutions. I advised on and implemented scalable architecture, code, algorithms, performance metrics, and bias evaluation outputs such that data scientists can deliver unique insights and robust models to partner schools in a low-touch way.

Grand Prize Winner: Data Visualization Challenge
The AHRQ Visualization of Social Determinants of Health Challenge invited participants to develop new online tools to present and encourage use of free, publicly available social determinants of health data to better understand and predict communities’ unmet healthcare needs.

I led a team of data scientists and researchers to build a submission to this challenge, which ended up winning the grand prize!
