Dimitrios Zekkos wins Shamsher Prakash Research Award

Dr. Dimitrios Zekkos, Associate Professor of Civil and Environmental Engineering, has won the 2017 Shamsher Prakash Research Award. | Short Read

The Shamsher Prakash Foundation annually selects one young engineer that has made significant contributions to the field of Geotechnical Engineering and/or Geotechnical Earthquake Engineering.

Zekkos has made remarkable strides in promoting sustainability and resiliency in landfills, through his work on mechanical properties of solid waste, dynamic characterization of landfills, and generation of energy from solid waste.

Professor Zekkos specializes in geoenvironmental engineering with a focus on solid waste mechanics and energy from waste, and in natural hazard assessment, with a focus on earthquakes and landslides. Zekkos has been developing novel experimental setups in the laboratory and the field to collect data that provide new insights into material response to a broad range of environmental conditions and stressors. Most recently, he has been using sensor-equipped robotic platforms to document  infrastructure field response. He has published more than 100 scientific publications and his research work has been recognized by several awards including the Middlebrooks Award, Collingwood Prize and Casagrande Award by ASCE.

Zekkos was selected by a committee of international experts from Chile, Canada, Japan, Sweden, Switzerland, and United States.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
