Dr Greg McNamara is an Assistant Professor in Sustainable Engineering and Energy Systems in the School of Mechanical and Manufacturing Engineering, Dublin City University. As one of only a very few established LCA practitioners in Ireland, he is, and has been involved in a wide variety of engineering-based research projects. Dr McNamara is currently working on the H2020 NewSkin project on advancing the industrial uptake of advanced surface nano-technologies. The focus of Dr McNamara’s early research was water and wastewater treatment system technologies; specifically, the environmental and economic impacts of treatment systems. Recent projects of note include the EU H2020 Saltgae Solution project (2016 – 2019); a system to treat saline wastewater from the food and beverage industry with microalgae. Prior to this, Dr. McNamara has worked on a variety of EPA funded water and wastewater treatment projects. Energy systems are central to Dr. McNamara’s current research and teaching, which includes renewable energy systems, energy storage, and the water energy nexus.
