Nicholas is currently a Ph.D candidate in Urban Science at the University of Warwick's Institute for the Science of Cities and an Assistant Research Scientist at NYU's Center for Urban Science and Progress. He obtained a Masters degree from NYU's Interactive Telecommunications Program in 2013 and launched Open Trash Lab - a living laboratory that seeks to create collaborative opportunities to explore and understand the impact and pervasiveness of urban waste. His current research is focused on the design and development of cyber-physical systems to quantify the urban environment and novel data-driven approaches to understand urban phenomena including waste generation, urban mobility and environmental processes.
