Biography

Dr. Omer is an associate professor at the Institute of Sustainable Energy Technology, Department of Architecture and Built Environment, Faculty of Engineering, the University of Nottingham, in the United Kingdom. Dr Omer has over 28 years of teaching and research experience in sustainable and renewable energy technologies, sustainable building technologies, building integrated renewable energy systems, refrigeration/cooling devices including ejector cooling, absorption and desiccant cooling system, and thermoelectric devices, phase change materials, and energy-efficient systems.

Dr. Omer has carried out a number of research projects funded by the European Union (EU), Engineering, Physical Science Research Council (EPSRC) in the UK, the Department of Trading and Industry (DTI) in the UK, the industry and the Greenpeace Environmental Trust related to the proposed project. He has published over 80 papers in refereed journals and conferences contributions.

Dr. Omer was the first to be involved in the design, installation, and monitoring of renewable energy facilities at the Angela Marmont Renewable Energy Centre, the Eco-energy house, and the Nottingham University Jubilee campus which have drawn considerable attention towards the department's role in the field of renewable and sustainable energy technologies nationally and internationally.

Dr. Omer is also a member of the Building Energy & Environment Research Group.

Expertise Summary

My expertise is in sustainable and renewable energy technologies, sustainable building technologies, building integrated renewable energy systems, EV and Hydrogen energy technologies, refrigeration/cooling devices including ejector cooling, absorption, and desiccant cooling system and thermoelectric devices, phase change materials, and energy-efficient systems.

Teaching Summary

Dr Omer is the director of one of the most successful master courses in the department "MSc course in Sustainable Building Technology", which is receiving a wide international interest.

He has contributed to University teaching strategy by establishing a number of memorandums of understanding (MOU) between the University of Nottingham and a number of Sudanese and Chinese universities, and through these he has facilitated annual scholarships from the Physical and the Environmental Centre of Khartoum to about 15 master students and 3 PhD students to a number of departments in the university including, engineering, medical and computer science.

Current teaching modules include:

1. Renewable Energy Technologies (Resources assessment, System design/sizing and assessment)

2. Energy Conversion Systems

3. Fuel cells and Hydrogen technologies
