Sangmin An has been an assistant professor in the Department of Physics of Jeonbuk National University, Republic of Korea since 2020. He received his PhD in physics (an AFM-based study on nanomaterials) from Seoul National University (SNU), Republic of Korea in 2013. Afterwards, he conducted research at the National Institute of Standard and Technology (NIST) in the United States for 3 years (2014–2016), focusing on the nanofabrication of optomechanical devices for AFM, and at SNU (3 years) as a research assistant professor focusing on AFM-based studies of nanoscale liquids, wear and friction, nanoscale sensors and nanoscale 3D printing. An is continuously focusing on multi-dimensional scientific issues (0D~3D) via advanced AFM combined with STM, SEM and optics.
