Research Objective

Biomedical Optics Laboratory is focused on developing novel optical methods based on interferometry, scattering and  manipulation of light, for the purpose of (1) imaging biological and medical samples, (2) understanding the physics of diseases, and (3) diagnosing and treating the disease. Hosted by the Department of Physics and the KAIST Institute (KI), the lab is performing highly interdisciplinary research at the interface between technology development, basic biological studies and clinical applications.

The area of research is optics, holography, and biophysics. Prof. Park and colleagues have published +140 peer-reviewed papers with +9,000 citations, including 3 Nat Photon, 3 Nat Comm, 1 Science Advances, 4 PRL, 5 PNAS papers. Two start-up companies with +50 employees have been created from his research (Tomocube, The.Wave.Talk).
