Dr Jaya Acharya Nepal

Lecturer in Civil and Structural Engineering

Jaya Acharya Nepal (BEng MSc PhD)is a Lecturer in Civil and Structural Engineering. She teaches Civil and Structural Engineering modules in both undergraduate and postgraduate level. Her area of research is mainly focused on performance assessment and optimal maintenance of deteriorating civil engineering structures.

    Dr. Jaya Acharya Nepal is a Lecturer in Civil and Structural Engineering within a School of Architecture, Computing and Engineering since 2015. Prior to that she was working as a Lecturer in Civil Engineering at University of Greenwich.

    Jaya has worked as a Research Fellow in Flood Risk Management funded by Natural Environment Research Council and the Institution of Civil Engineers at University of Greenwich in collaboration with HR Wallingford. Jaya was awarded her PhD in Structural Engineering from the University of Greenwich funded by RAE Formulaic. Before joining the University of Greenwich, she has worked as a lecturer and design engineer responsible for analysis and design of civil engineering structures after completing her masters in Civil and Structural Engineering and Bachelor in Civil Engineering.

    Jaya has a strong research background in various areas of civil engineering, including lifecycle performance analysis, stochastic deterioration modelling, time-dependent reliability analysis and risk-cost based maintenance optimization, structural health monitoring, advanced numerical modelling, innovative and smart infrastructure, stochastic deterioration modelling and flood-risk modelling. She developed novel methodologies for forecasting the performance deterioration of flood defence infrastructures, performance assessment of corrosion damaged reinforced concrete structures and time-dependent reliability analysis and optimised maintenance strategy of civil engineering infrastructure. She is the author/co-author of several peer-reviewed journal articles and conference papers. She frequently served as a peer reviewer for international conferences and journals.
