Welcome to the Holman Research Group home page.
Research in the Holman lab lies at the intersection of organic, organometallic, and solid-state/materials chemistry. Broadly speaking, our research is focused in two areas: i) recognition, self-assembly, and/or supramolecular chemistry―that is, the designed organization of molecules into multi-component species via non-covalent (i.e. reversible, individually weak) bonds; and ii) crystal engineering―the design and study of molecule-derived crystalline materials via supramolecular principles. Specific avenues of research can be found on the Research page, but it is true to say that projects in the Holman Group are highly multidisciplinary, allowing students (high school, undergraduate, and post-graduate) and post-doctoral researchers to develop expertise in synthetic organic and/or organometallic chemistry, physical organic chemistry, solid-state chemistry, powder and single crystal X-ray diffraction, various spectroscopic techniques (e.g. NMR, Raman, and, ocassionaly, more exotic techniques such as neutron scattering), thermal analysis (e.g. tandem TGA-mass spectrometry, DSC), gas sorption, etc. Consult the Research page for more information on specific projects and the availability of research positions.
We are located in the Department of Chemistry at Georgetown University.
