Areas of Expertise

My lab's research is in the area of inorganic and organic materials chemistry and nanotechnology, with a particular interest in self-assembling systems and device applications. One area of investigation has involved the preparation of liquid crystalline compounds (both organic and inorganic) which self-assemble into electrically anisotropic structures. Our approach enables us to tune a number of specific characteristics of these one-dimensional materials, such as temperature range for self-assembly and the strength of intermolecular interactions by means of molecular design and synthesis. More recently, we have become involved in aspects of self-assembly that have applications in the development of organic solar cells. We are interested in patterning surfaces via methods such as microcontact printing, DPN, and nanosphere lithography, as well as designing novel self-ordering donor and acceptor materials that can be used in photovoltaic devices. Students in my lab are involved in the synthesis and characterization of both organic and inorganic compounds, as well as both small molecule and macromolecular systems. Students also have the opportunity to gain experience in the characterization of chemically patterned surfaces and the assessment of performance of organic-based solar cells. Most of our work is carried out at Williams; for techniques that are currently unavailable at Williams, we make use of collaborative relationships at various other institutions, such as RPI and MIT. Our research has been funded by NSF-RUI, NSF-MRI, ACS-PRF, and through our on-going collaborataion with the NSF NSEC program at RPI. Images from our research
