Dr. Amassian is a materials scientist and engineer who has co-authored more than 210 publications in peer-reviewed journals and has delivered over 130 invited and keynote lectures. His research is in the area of energy materials, with an emphasis on energy harvesting materials and devices, such as organic photovoltaics, metal halide perovskite photovoltaics, and colloidal quantum dot photovoltaics. His group investigates the solution processing of semiconductor materials using lab-scale and fab-scale methods and develops advanced in situ characterization methods to gain insight into the non-equilibrium solidification and phase transformation of materials from solution to solid. Dr. Amassian’s work has received >20,000 citations and an h-index of 73 (Google Scholar). He was named a Highly Cited Author on Web of Science in 2020 and was inducted as a member of the Royal Society of Chemistry. He was previously awarded the Career Development SABIC Chair for his pioneering work on solution-processed optoelectronic materials and is the recipient of the American Vacuum Society’s Electronic Materials Postdoctoral, the NSERC (Canada) Postgraduate and Postdoctoral Fellowships.

Dr. Amassian obtained his B.Eng. (2001) and Ph.D. (2006) in Engineering Physics from Polytech Montreal in Canada, and he completed a postdoctoral fellowship in Materials Science and Engineering at Cornell University with George Malliaras. Amassian was appointed Assistant Professor of Materials Science and Engineering in 2009 at the King Abdullah University of Science and Technology (KAUST), where he was one of 75 faculty at the founding of the university. He joined NCSU in 2018 as Associate Professor and was recently appointed Professor (2021).

He is a pioneer in advanced characterization during solution-processing of organic and hybrid semiconductor materials used in electronics and photovoltaics and is best known for introducing in situ x-ray and optical diagnostics during spin-coating and meniscus-guided processes, such as blade coating. His research now develops and utilizes robotics in combination with characterization and artificial intelligence to establish formulation-process-structure-property relationships in an organic, quantum dot, and metal-halide hybrid perovskite semiconductor materials and devices with a primary focus on stability, efficiency, and scalable and eco-friendly manufacturability. His work has been highly interdisciplinary and collaborative, at the intersection of materials science, chemistry, and physics, as well as material, chemical, electrical and industrial engineering. His publication and funding track records reflect the transdisciplinary, collaborative, and international DNA of his collaborations.

Dr. Amassian is the co-founder of AWOS Technologies and co-founder and Chief Technology Officer of Bay Nano Technologies, which was awarded the eGames Daugherty Endowment.
