Dr Al-Dadah is a Lecturer in Thermofluids within the Department of Mechanical Engineering having previously undertaken a BEng in Palestine and a PhD from London South Bank. She has researched and supervised research projects in the field of heat transfer and refrigeration and published over 30 papers in reputable journals and international conferences.

Dr Al-Dadah is also a part of the Birmingham Plastics Network, an interdisciplinary team of more than 40 academics working together to shape the fate and sustainable future of plastics.  This unique team brings together chemists, environmental scientists, engineers, philosophers, linguists, economists, artists, writers, lawyers, and experts in many other fields, to holistically address the global plastics problem.


  • PhD in Electrohydrodynamic Enhancement of Heat Transfer (London South Bank University, 1994)
  • BSc in Mechanical Engineering (BirZeit University, Palestine)


Dr. AL-Dadah graduated from BirZeit University in 1986 with BSc in Mechanical Engineering specialising in air conditioning and refrigeration. She worked at the cooperation of fishermen in Gaza strip to manage the ice factory and the cold storage rooms. With a British council scholarship, she studied at Grimsby college the second year of the higher national diploma in refrigeration and with scholarships from three Arabic organisations and London South Bank University, she studied for PhD. Dr. AL-Dadah worked for one year at London South Bank and from February 1996, she is working at the University of Birmingham. As a lecturer in thermofluids
