Mark has a voracious interest in nanotechnology, renewable energy, and the intersection between the two. He is a doctoral candidate in Dr. Pfefferle's lab, and specializes in the synthesis and characterization of nanoporous materials for applications in hybrid organic/inorganic solar cells. This approach to photovoltaics utilizes light-absorbing plastics to donate electrons to an aligned porous semiconductor membrane. This system is advantageous because it circumvents the typical problems in polymer photovoltaics of poor charge separation due to low exciton diffusion lengths, and poor charge extraction due to disordered, tortuous, or discontinuous charge collection pathways.
In addition to his research into photovoltaics, Mark also works with resonant Raman spectroscopy for the characterization of carbon nanotubes and other materials, and the synthesis of cupric oxide nanomaterials such as nanowires, nanotubes, and nanosheets.
When he's not in the lab, Mark enjoys throwing a frisbee, rehearsing Javanese gamelan, playing kickball, reading news, and meditation.
Mark did his undergraduate work at Yale, studying chemical engineering, where he first started working in the Pfefferle lab performing synthesis of mesoporous catalyst for selective growth of single-walled carbon nanotubes with small diameters.
