How I Work

Bridging Research & Engineering

I'm driven by a deep interest in how data shapes knowledge, decisions, and infrastructure. I enjoy working at the intersection of research and engineering, where algorithms meet real-world systems to solve practical problems.

Interests

Technology

I'm passionate about understanding and developing intelligent systems at the intersection of society, data, and science.

AI & Machine Learning Systems
Data-Driven Decision Making
Socio-Technical Systems

Academic

Reading across technology, society, philosophy, and mathematics, with a focus on the epistemology of data and the science-society interface.

Research

I'm inclined towards studying complex dynamical systems around humans, urban environments, and emerging technologies through networks and data-driven approaches.

Human Dynamics
Urban Complex Systems
Cultural Networks
AI Technology Impact

The Common Thread

What connects all these interests is a fascination with emergence — how simple rules and interactions give rise to complex behaviors and patterns. Whether it's in technological systems, social structures, or natural phenomena, I'm drawn to understanding how complexity arises from simplicity and how we can leverage this understanding to build better systems and make more informed decisions.
