Marc Boudreau utilizes organic chemistry and chemical biology to study antibiotic resistance in bacteria. New potential enzyme inhibitors or probes for target identification are synthesized in the laboratory. Their biological activity and mechanism of action is studied in detail, which is utilized to inform the rational design of improved inhibitors.
Christine Caputo designs and synthesizes new organic and organometallic complexes using Earth-abundant metals that can act as catalysts or precursors for the development of new photoactive materials. Current research projects employ photochemical and electrochemical techniques to study the catalytic conversion of small molecules into more valuable sustainable fuel precursors using sunlight.
Arthur Greenberg employs strained organic molecules to study biological and toxicological mechanisms. This includes chemical and enzymatic studies to investigate the reactions of cytochrome P450 isoforms with oxepins in order to understand metabolic ring-opening of benzene.

Margaret Greenslade applies physical chemistry techniques including spectroscopy and electron microscopy to study the optical, chemical and morphological properties of fine atmospheric particulates, known as aerosols. Aerosols play important roles in diverse fields such as climate change, air pollution, atmospheric chemistry, health and drug delivery.

Richard Johnson uses a combination of high level theory and experiments to study reactive intermediates and complex organic reaction mechanisms. Current efforts are focused on proton and free radical catalyzed rearrangements of polycyclic aromatics. His group also develops new methods to predict the regio- and stereochemistry of organic reactions.

Howard Mayne is interested in how the forces between molecules influence their behavior when in groups. He uses computations to model how these forces shape small clusters of molecules, and whether molecules can self assemble into patterns when placed on solid surfaces. The latter property is particularly important in materials science and nanotechnology.

Glen Miller performs research at the intersections of organic chemistry, materials science, and nanotechnology. His group synthesizes and characterizes both small molecules and derivatives of nanostructured carbons. They then utilize these species in structural materials and in thin-film electronic devices like photovoltaics and light emitting diodes.
J. Phys. Chem. C., 2014, 118(46), 26955-26963.
Sam Pazicni divides his research interests between the classroom and the laboratory. In the classroom, his group explores how language relates to learning chemistry as well as abating students’ illusions of competence; in the laboratory, his group prepares and studies synthetic metalloenzymes and metalloproteins, based on collapsible polymer architectures.
J. Chem. Educ., 2014, 91(12), 2045-2057.
Roy Planalp studies transition-metal coordination chemistry, which generally includes synthetic and physical inorganic chemistry applied to problems in the life sciences and environmental sciences. The focus is on ligand design and synthesis, currently the development of ratiometric fluorescent sensors of copper for wastewater sampling, and mechanistic studies of phosphodiesterase metalloenzymes.

Chuck Zercher develops synthetic methods and strategies designed to facilitate the preparation of novel biological mimics and natural products. The formation and selective fragmentation of cyclopropanes are key components of the selective methodologies. Synthetic targets include cyclopropanols designed as peptide mimics and cytotoxic spiroketal natural products.

Diverse Research Opportunities
The Department of Chemistry is the only department that has existed for the entire history of UNH; we have a long-standing tradition of achievement in the molecular sciences. Our vision for the future is not confined by the traditions of the past. We work to combine approaches and interface with other disciplines where interesting chemical questions exist. Our continuing commitment to quality and innovation is reflected in the multifaceted research themes of the Department:
analytical methods and methods development (AM&MD)
This research effort develops tools and methods to analyze, characterize, manipulate, and sense molecules, ions, and small particles, especially as related to toxins, environmental species, and materials.
bio-inspired chemistry and chemical biology (BIO)
In these areas, expertise from inorganic/organic synthesis, analytical chemistry, and biochemistry are applied to biological systems at the molecular and macromolecular levels as well as in whole cells.
chemistry education research (CER)
We are one of the few Chemistry Departments in which multiple faculty members perform Chemistry Education Research—combining disciplinary expertise with methodologies/models from education, the learning sciences, and psychology to better understand and improve chemistry teaching and learning.
energy and environmental science (EN&ENV)
These areas make use of synthetic, physical, and analytical chemistry to molecularly harness energy from sunlight and to probe/sense trace species in, and potential chemical threats to, the environment.
macromolecules, materials, and nanoscience (MM&N)
Materials-related research is very strong in our Department, and it encompasses a diverse range of projects, including molecular materials, nanomaterials, computational chemistry, surface chemistry, colloids, and polymers.
The diverse research interests of our faculty do not permit their easy classificaiton in to the traditional areas of Chemistry. However, they are listed here in a matrix representing the spectrum of department research, with their traditional classification indicated by a diamond (♦) and interdisciplinary research interests indicated by a closed circle (•).
