Hi, I'm Vignesh :)

Two animated cats running across a small data-inspired scene

I'm studying Econometrics & Mathematical Economics at LSE, with interests in causal inference and applied data science. I'm particularly interested in causal questions: why does X cause Y, who is affected, and what can we do with that knowledge? I want to bring econometric research designs together with machine learning to investigate these questions, understand how effects vary across people and settings, and turn evidence into useful decisions. (Below I've grouped a selection of my research, coursework, collaborative work and personal projects into three areas: causal inference, machine learning projects and some wacky side projects)

More broadly, I like data science because it lets us look at numbers, discover relationships, and use what we learn to inform decisions around the world. I'm interested in both the methods and the substantive problems they help us understand. My curiosity has taken me into multilingual language technology, environmental data and small tools built in response to everyday problems (and I am excited to explore new fields!). I'm open to collaborating on new research ideas in causal inference and applied data science. If these interests overlap with yours, or you have a question you'd like to explore together, feel free to email me.
