I am a Research Fellow at University College London.

My works are in the analysis of PDE. I specialise in microlocal and semiclassical analysis, spectral and scattering theory, control theory, and quantum dynamics.

Here is my curriculum vitae. I was a student of Jared Wunsch. I am mentored by Jeffrey Galkowski.

I am not teaching in 2023–2024.

My email address is ruoyu.protect..wang@.protect.ucl.ac.protect..uk. My office is Room 600, 25 Gordon St..
