About Babs

Economics taught me to ask why. Data science gave me tools to test what works.

I build analytical systems for decisions that affect people, institutions, and markets—from health financing in Rwanda to pricing systems in Europe and digital-health tools across emerging markets.

The through-line

01

I care about the distance between a technically correct answer and a genuinely useful one.

The best model is rarely the most complicated model. It is the one built around the decision, honest about uncertainty, and clear enough for people to challenge and use.

My path began in mathematics and quantitative economics, moved through political-violence research and business intelligence, and developed into applied machine learning across healthcare, pricing, recommendations, and experimentation.

That breadth shapes how I work today: start with the institutional context, build the minimum credible evidence, and design the output around action.

How I work

03
01

Start with the decision

I define who acts, what changes, and what a useful answer must contain before reaching for a model.

02

Make uncertainty visible

I separate signal from confidence, document assumptions, and build checks that invite scrutiny rather than hide it.

03

Design for adoption

I translate across research, engineering, policy, and product teams so evidence can move into real workflows.

Toolkit

The short version

I bring economic reasoning, production-minded data science, and clear communication to high-stakes decisions.
