Dr Mihai Caleap's research is multi-disciplinary encompassing various engineering disciplines, applied mathematics, computer science and physics. His research interests cover various aspects of wave propagation in heterogeneous complex media, including composite materials and metamaterials; his work encompasses ultrasonic array imaging, multiple scattering and ultrasonic particle manipulation.

Mihai is currently designing multifunctional metamaterials for various applications including novel human-computer interfaces, haptics, directional audio, acoustic levitation, reconfigurable ultrasonic filters, ultrasonic meta-lenses for super-resolution imaging of tiny defects, vibration cloaking of sensitive components, and stealth applications for the military and security sectors. 

Current activity involves: 

  • Spatial sound modulators 
  • Meta-surfaces for sound and micro-wave control
  • Assembly of reconfigurable colloidal crystals and micro-particle super-lattices due to a synergy of fundamental nanoscale forces (e.g. acoustic & magnetic radiation forces)
  • Acoustic, elastodynamic and electromagnetic metamaterials
  • Particle manipulation with ultrasound
  • Acoustic quasicrystals


Mihai has had a particularly diverse education which has included Fine Arts, Mathematics, Physics and Engineering. His PhD was obtained from the University of Bordeaux, France, where he briefly worked (for 9 months) as an Assistant Professor in Mechanical Engineering. From 2009 to present he worked as an academic at the University of Bristol, UK, where he went to become an international leader in his field. Mihai is a recognised expert in metamaterials and field-directed colloidal assembly. He recently acted as external consultant for NASA’s MaterialsLab Open Science Campaign for Experiments on the International Space Station, and for ANR's (French National Research Agency) Projects for Science. In 2015, Mihai founded Wave Engineering Bristol – a workshop series aimed at scientists and academics in Bristol to promote, share, and discuss theory and applications of wave engineering in physical contexts including - but not limited to - acoustics, elasticity, optics, photonics, seismology and water wave theory. Most recently, Mihai founded Metasonics – a spin-out between the Universities of Bristol and Sussex in the UK – and promises a sound revolution in consumer technology.

Mihai is on a mission to increase the openness, integrity, and reproducibility of scholarly research. In 2016, he set up The Open Science Incentive which aims to raise awareness and encourage an open science culture, and support increased collaboration and engagement between research and society that can lead to higher social and economic impacts of public research. Mihai works on ways to introduce engineering concepts to large public audiences via interactive hands-on activities. He developed a series of STEM workshops for teachers, created Art-Science exhibitions, and brought his research to various science festivals. Mihai is currently engaged with We The Curious and Lick Me I'm Delicious
