Haixing Miao is a Birmingham Fellow and also STFC Ernst Rutherford Fellow in the School of Physics and Astronomy

His current research interests are improving sensitivity of quantum-limited measurement devices that include gravitational-wave detectors and optomechanical sensors in general, and using these devices to study quantum behaviours of macroscopic objects.


  • PhD in Physics, University of Western Australia, 2010        
  • BA in Astrophysics, University of Science and Technology of China, 2006


Haixing Miao started his postgraduate research in the gravitational-wave group at the University of Western Australia in 2007. He got his PhD in 2010. Afterwards, he moved to California Institute of Technology as a postdoctoral scholar, where he continued working on quantum aspects of gravitational-wave detectors and optomechanical devices in general.

He joined Birmingham in 2014 as the Marie-Curie International-Incoming Fellow. In 2016, he was awarded the STFC Ernst Rutherford Fellow and also the Birmingham Fellow.
