Summary

I am a computational modeller, theory-builder & data scientist/machine learning researcher interested in There is massive potential now for AI/ML research to improve public discourse and social welfare via intelligent infrastructure in social and economic domains. Dampening social polarization and supporting effective sustainability transition policy addressing the climate emergency are two critical efforts.

Towards these ends, I coordinate interdisciplinary collaborations with domain experts in which I also contribute technical mathematical and computational expertise (theory and models/algorithms for decision-making agent learning, statistical inference, data analysis).


Trained in the theoretical biophysics community, I worked in computational neuroscience for some time, most recently on the science of decision-making in NeuroAI. Now, it's typically social scientists (social psychologists/ sociologists/ political scientists/ economists) who have identified the problems I work on. My approach to these problems stems from my expertise in machine-learning and system modelling. Here's an high-level depiction that motivates some current work:



In addition to supporting applications, I see these approaches as part of a modernized computational social science grounded in large-scale, quantitative approaches. See Research and Publications sections for more details.
