Xi Chen uses multiscale theoretical, experimental, and numerical approaches to investigate various research frontiers in materials and mechanics addressing challenges in energy and environment, nanomechanics, and mechanobiology.

Research Interests

Carbon dioxide capture, utilization, and storage; energy storage; energy conversion; multi-scale simulation; soft materials and robotics;, morphogenesis; mechanobiology; nanomaterials; nanomechanics.

Research Areas

His wide research interests span from energy (novel energy conversion materials, large-scale energy storage systems, genomics of energy materials, fuel cells and electric car 2.0) to environment (negative carbon emission, carbon dioxide utilization, nanomaterials for water treatment and agriculture revolution) to bioengineering (morphogenesis, bio-inspired self-assembly process, soft robotics, cellular and molecular biomechanics) to nanotechnology (nanoindentation, nanomechanics and low-dimensional materials).

Chen pioneered nanofluidic energy conversion and, based on the ultra-large surface area between nanoporous materials and functional liquids, he developed affordable material systems that can convert among electrical, thermal and mechanical energies with high efficiency. He elaborated the mechanism of a series of counterintuitive reversible chemical reactions and developed several moisture-swing absorbents for capturing carbon dioxide from ambient air with very low energy and material cost. Using simple mechanics theories, he pioneered the study of morphogenesis of various fruits, vegetables, animals, tissues, and cells, and further implemented into stress engineering of 3D self-assembly, as well as proposed innovative locomotion modes of soft robots. He has also extensively studied material genomics and established nanomechanics frameworks and reliable characterization methods of numerous energy and nanomaterials.

Chen received his BS in engineering mechanics from Xi'an Jiaotong University in 1994 (at the age of 18), and a PhD in solid mechanics  from Harvard University in 2001. He has published over 300 journal papers and has a h-index well above 40. He received the NSF CAREER Award in 2007, the Presidential Early Career Award for Scientists and Engineers (PECASE) in 2008, ASME Sia Nemat-Nasser Early Career Award in 2010, SES Young Investigator Medal in 2011, ASME Thomas J. R. Hughes Young Investigator Award in 2012, and a number of international recognitions from Japan, Korea and China. He is a Fellow of ASME. He joined the faculty of Columbia Engineering in 2003. Prior to Columbia, he did postdoctoral research at Harvard University.
