Dr Michaela Bray

PhD, MEng, BSc

Lecturer - Teaching and Research

School of Engineering

Michaela Bray has worked in Civil Engineering in both research and industry.  She was employed by consulting engineers, Buro Happold where she gained experience in coastal defence design and steel structure design.  In addition she has experienced working for contracting engineers Chrisiani & Nielson with whom she worked on site in the construction of Avon Ring Road.

She completed PhD at the Water, Environment Management Research Centre (WEMRC), University of Bristol. Her research topic focused on the use of weather radars, rain gauges and numerical weather prediction models for hydrological purposes.

She has worked on several projects including:

  1. EU FP7 SPRING project ‘Scoping China’s Environmental Research Excellence and Major Infrastructure: Foresight, Potentials and Roadmap’
  2. Flood Risk Management Research Consortium
  3. Collaborated with a commercial company, Landmark
