[2] Lim is interested in nucleocytoplasmic transport regulation, its impact on cellular function, and how this phenomenon can be leveraged towards bio-inspired applications.

He studies how karyopherin receptors facilitate this highly rapid and selective process through nuclear pore complexes (NPCs).

Lim combines biophysical, nanotechnological, and cellular approaches to unravel the emergent physical principles that underlie biological function and then verify the results in biomimetic systems.

His key contributions include a karyopherin-centric model of the NPC and the discovery of two-dimensional transport control in artificial systems.

Lim is a co-inventor of ARTIDIS ("Automated and Reliable Tissue Diagnostics"), an atomic force microscope-based innovation for cancer diagnosis.
