I also specialize in in-situ nanoscale quantification of cementitious materials and metals using advanced characterization techniques. My interest in this field grew during my graduate studies and after attending the First International Conference on Sustainable Production and Use of Cement and Concrete.\u003Cbr\u003E\u003Cstrong\u003ECitrin\u0026nbsp;\u003C\/strong\u003E- Several years ago, I supervised a masters project using an automated imaging system to identify construction materials. My core interests are in terahertz imaging and applications of machine learning, so the IMS project brought these two together.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWhat questions or challenges sparked your current research?\u0026nbsp;\u003C\/strong\u003E\u003Cbr\u003E\u003Cstrong\u003EFanijo\u003C\/strong\u003E - Buildings account for 39% of global energy-related CO2 emissions and 35% of energy consumption, primarily due to manufacturing, materials, and transportation. Therefore, advanced research into innovative construction materials derived from waste streams is essential to reduce carbon emissions throughout the building lifecycle.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECitrin\u003C\/strong\u003E - The societal problems of how to reuse construction waste is urgent. Identifying those materials that can be reused and separating them from those that are tainted presents fascinating technical problems and is a tremendous challenge.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMatter and systems refer to the transformational technological and societal systems that arise from the convergence of innovative materials, devices, and processes.
