Dr. Tehmina Ayub

Professor

Biography

Tehmina Ayub is a Professor of Civil Engineering at NED University of Engineering & Technology (NED-UET), Karachi, and the first woman to attain this position in the department’s 100-year history. She holds a Ph.D. in Structural Engineering from UTP Malaysia, where she was awarded a Gold Medal at ITEX 2014 and secured a Malaysian patent. Dr. Ayub serves as Associate Editor of the NED University Journal of Research and sits on the reviewer panels of several leading international journals and conferences. She has supervised numerous PhD and Master’s students and has served as a jury member for both international and national competitions. Dr. Ayub founded Pakistan’s first Durability Lab in civil engineering at NED-UET. Her research centers on sustainable construction materials, including LC3, the use of industrial waste, and structural strengthening in challenging environments. She has successfully led multiple funded research projects and teaches core courses in advanced construction materials and structural design. Dr. Ayub is a fellow of the Women’s Leadership Program at Michigan State University and the Institution of Engineers Pakistan (IEP). She is also a member of the American Society of Civil Engineers (ASCE) and the American Concrete Institute (ACI). In recognition of her outstanding contributions to engineering education, she received the “Fatima Jinnah and Benazir Bhutto” Award for services in engineering from the Sindh Commission on the Status of Women, Pakistan.
