Mamadou Diallo was trained both as an engineer and physical chemist. He holds an Engineer Diploma in Mineral Engineering from Ecole Nationale de L’ Industrie Minerale (Rabbat, Morocco), a Master of Science degree in Chemical Engineering from Colorado School of Mines, a Master of Science degree in Chemistry and a Ph.D. degree in Environmental Engineering from the University of Michigan. Prof. Diallo also completed post-doctoral training in Computational Chemistry at the California Institute of Technology. His current research interests and activities focus on the use of dendritic nanomaterials as building blocks to develop novel adsorbents, membranes and filtration systems for water treatment, reuse and desalination. He is Director of Molecular Environmental Technology of the Materials and Process Simulation at Caltech. He co-founded a start-up company Aqua Nanotechnologies (ANT) to scale-up and commercialize high performance media for water treatment and environmental/industrial separations. Prof. Diallo is currently a Professor at Korea Advanced Institute of Science and Technology and California Institute of Technology.
