Biography

Dr. Manousos Valyrakis is Lecturer in Water and Environmental Engineering, at Civil Engineering and member of Water Group of the Infrastructure and Environment Research Division within the School of Engineering, in August 2012. Before joining the University of Glasgow, he worked at Virginia Tech and VCCER as a Research Associate, where he further researched the environmental impacts and associated risks from resource extraction industries. He gained a PhD in Environmental Hydraulics from the Department of Civil Engineering at Virginia Tech, funded by NSF, in 2011. He has a Diploma (5year degree in Civil Engineering) with distinctions and a MSc (Civil and Environmental Engineering), from Aristotle University of Thessaloniki.
 
Dr. Valyrakis has about 10 years experience in environmental hydraulics and experimental/computational fluid mechanics. He is the recipient of several awards and has served as session chair on several international conferences. He has also served as a reviewer and member of the editorial board for a book and many international journals and conferences. He has been invited to present his research on several venues and he has authored or co-authored more than 40 outputs, including many peer reviewed journal papers and 2 invited book chapters.
 
He is the manager of the Water Engineering Laboratory (Rankine Building) where he is currently leading research activities relevant to experimental flow dynamics and eco-hydraulics.

Research Interests

Dr. Valyrakis is a Lecturer in Water and Environmental Engineering and the manager of the Water Engineering Lab, at University of Glasgow. He is currently pursuing research spanning the interface of water and energy resources management, with focus on water engineering and eco-hydraulics, for a variety of physical systems (rivers, estuaries and coasts). Dr. Valyrakis has conducted fundamental and applied research in the fields of environmental fluid mechanics and multiphase flows (sediment transport and fate of contaminants) and the environmental impact of resource extraction industries (carbon management). He has investigated the interaction of flows with their solid boundary across a wide range of scales - from the micro (particulates and particles) to the meso (scouring and bedforms) and the macro (catchment) scale. His expertise ranges from physical modeling and experimental methods (lab methods and development of sensors for environmental monitoring) to utilization of appropriate numerical modeling tools.
