PhD Candidate @ UVA
Applying and developing AI to understand how science and technology evolve.
Hi! I'm MJ (Munjung Kim), a PhD candidate in Data Science at University of Virginia, advised by Professor Ahn.
My research focuses on using and developing advanced AI and machine learning techniques to understand innovation in science and technology. These days, I'm also interested in exploring how large language models can be enhanced and understood through the lens of collective intelligence.
Before joining the PhD program, I completed my undergraduate studies in Physics at Pohang University of Science and Technology (POSTECH) in Korea.
Scientists shift their research interests—or "move" the space of knowledge—sparking new ideas and novel methodologies. Drawing inspiration from the boids model of collective animal behaviors, we characterize individual research movements using simple rules: alignment, cohesion, and separation.

We calculate the disruption index of 3,237 U.S. AI patents (2015-2022) and link them to job tasks to distinguish between "consolidating" AI innovations that reinforce existing structures and "disruptive" AI innovations that alter them.

We propose a new, continuous measure of disruptiveness based on a neural embedding framework that better distinguishes disruptive works, such as Nobel Prize-winning papers, from others.

Using neural embedding methods, we show that topic disparity is negatively associated with citation count, indicating that less conventional research tends to receive fewer citations than conventional research.
