Summary:

The Laboratory for Advanced Materials at Pittsburgh (LAMP) under the direction of Professor Paul W. Leu, focuses on designing and understanding advanced materials by computational modeling and experimental research. Simulations and experiments are used in a synergistic manner to study the mechanical and electronic properties of nanomaterials and surfaces for various applications.

The goal of LAMP is to design better material systems through a combined modeling and experimental approach. Much in the same way that finite element modeling is now foundational in mechanical engineering design, multiscale and device modeling will become increasingly important in the prediction and understanding of nanomaterial and surface properties. In addition, these techniques can be used as a design tool for evaluating and optimizing various design metrics. Current areas of interest include 

  • Ab initio modeling of nanomaterials and surfaces 
  • Combining physical simulations with optimization methods 
  • Nanomaterial manufacturing and characterization
  • Solar cells
