Starting 2017, Dr. Carnacina has been holding the position of Senior Lecturer in Civil Engineering at Liverpool John Moores University within the School of Civil Engineering.
Prior to this he has been Lecturer and Researcher in River Engineering at UNESCO-IHE Institute for Water Education within the department of Water Science and Engineering. In 2006 he obtained his master degree in Hydraulic, Transportation and Territory Engineering from the University of Pisa, Italy. In 2010 he obtained his Ph.D. in Civil Engineering from the doctorate school of the University of Pisa “Leonardo da Vinci” Italy, with a thesis on the effect of debris accumulation on bridge pier scour. Since 2007, he has also been a member of the professional body of Civil Engineers of the province of La Spezia, Italy.

Previously, he was involved in the CARNOT/VITRE research project on sediment transportation of combined sewer networks using acoustic devices at the French Institute of science and technology for transport, development and networks (IFSTTAR). There, he analysed the evolution and main morphological features of organic sediment deposits.

After that, he worked for more than 5 years at AIR Worldwide, a catastrophe modeller firm, where he developed fluvial, pluvial and storm surge stochastic numerical models for the continental United States, Brazil, China, Central Europe, UK and Japan. There, he also worked as model manager and scientific lead for the new North Sea storm surge model in collaboration with Deltares, which resulted in development of new solutions using Delft3D-Flexile Mesh.

He is interested in local erosion in correspondence of hydraulic structures such as bridge, river training structures and dams, large scale numerical flood models and flood protection. He has also contributed to the study of sustainable river training structures, with focus on local erosion phenomena and morphology, design, energy dissipation and two phase flow development. His research will focus on the sustainable impact of hydraulic structures with focus micro-hydropower development in rural regions use of sustainable resource to optimize efficiency and minimize the environmental impact.
