RESEARCH EXPERIENCE:
MCD spectroscopy:  I have extensive experience in measuring and analyzing magnetic circular dichroism (MCD) spectra at both room and cryogenic temperatures.  Although the MCD technique is somewhat specialized, it often provides key insights on the electronic structures of high symmetry heteroaromatic compounds, such as porphyrins and phthalocyanines, which are not readily available using other characterization methods.  In recent years, my research has largely focused on using Michl’s perimeter model (a conceptual framework used to analyze the results of MO calculations of aromatic and heteroaroamatic ?-systems) to identify key trends in the electronic structures of structurally related porphyrinoid compounds which shape the optical and redox properties.  I have also studied the MCD spectroscopy of hemes in the context of the iron-regulated surface determinant proteins of the Staphyloccocus aureus hospital superbug to derive information about the spin state of the central ferrous or ferric ion and its coordination environment within the protein.

Theoretical calculations:  I have carried out TD-DFT and INDO/s calculations on a wide range of porphyrinoids synthesized by over a dozen different research groups from around the world.  Trends observed in the MCD spectra of structurally related porphyrinoids have been used to validate the theoretical descriptions of the electronic structures.  One of my future research goals is to use molecular modelling and Michl’s perimeter model to carry out the rational design and synthesis of novel porphyrinoids that are suitable for use in practical applications such as dye-sensitized solar cells and near-IR fluorescent dyes.  Recent collaborative research on BODIPY dyes with Prof. Zhen Shen of Nanjing University has provided an opportunity to apply insights derived from research on porphyrinoids to a wider range of dye molecules.

Electrochemistry:  I have extensive experience in carrying out CV and DPV measurements.  During my doctoral research in Prof. Martin Stillman’s laboratory at the University of Western Ontario, I successfully designed cells which enabled CV and DPV measurements to be made under an inert atmosphere using a minimal amount of solution and supporting electrolyte.  I also designed cells for use in the sample bore of a superconducting magnet to enable in situ spectroelectrochemical measurement of the MCD spectra of highly air-sensitive ?-anion radical species.  The redox properties of porphyrinoids are an ongoing area of interest, since they are directly related to the trends in the electronic structure that are studied by optical spectroscopy and theoretical calculations, and also play a key role in determining whether porphyrinoids are suitable for practical applications.

Photochemistry:  During my doctoral research, I also gained considerable experience in using photochemistry to generate highly air-sensitive porphyrinoid ?-anion radical species in vacuo for spectroscopic measurements.  I subsequently studied the spectroscopy of air stable ?-anion radical species of porphyrinoids with novel structures, which result in marked decreases in the first reduction potential.  These species could be used in artificial photosynthesis and catalysis applications.  Currently, it is only the ?-cation radicals of porphyrinoids that tend to be used in this context, since most ?-anion radicals are highly air-sensitive.  A key future research goal would be to use Michl’s perimeter model and the trends predicted in TD-DFT calculations to carry out the rational design and synthesis of the low symmetry phthalocyanine analogues which are best suited to this type of research.

CD spectroscopy:  I recently wrote a book with Prof. Nagao Kobayashi of Tohoku University for publication by the Royal Society of Chemistry on the theory of CD and MCD spectroscopy and the quantitative analysis of the spectral data derived from these techniques.  I have carried out a limited amount of research on the CD spectroscopy of aza-BODIPY dyes and other optically active polymers and complexes.  Many researchers find the quantitative approaches to the analysis of CD spectral data quite challenging, so there could be considerable scope for collaborative research in this regard.

Emission spectroscopy: I have also carried out various fluorescence and phosphorescence measurements including both steady state emission spectra and the lifetimes of singlet and triplet excited states.  Studying the effect of different types of modification to the structure of porphyrinoid ligands and other types of dye molecule on the observed ΦF and Φ? values would be an obvious future research direction.

EPR spectroscopy:  I have considerable experience in measuring and analyzing the EPR spectra of air sensitive paramagnetic porphyrinoid radical species at both room and cryogenic temperatures, including experiments at ca. 4 K in which liquid helium was used as the coolant.  My experience with several different specialist spectroscopic techniques could be readily applied to a wide range of projects in inorganic and bioinorganic chemistry.
Software Development:  I have had extensive experience in developing in house software to carry out highly specialized types of data analysis related to MCD spectroscopy such as the simultaneous spectral band deconvolution analysis of UV-visible absorption and MCD spectra and deriving values for excited state magnetic moments from A1/D0 ratios.  I also developed software to provide user interfaces, which enabled the remote control of Jasco and Cary spectrometers and a Princeton Applied Research potentiostat, prior to this type of software becoming commercially available.  There is considerable scope for applying this experience in the present day based on the use of application macros.

Analytical Chemistry:  In the late 1990s, I spent two years carrying out analytical chemistry research on the treatment of wastewaters using H2O2 and UV light.  The research was largely funded by one of the leading industrial companies in the field and involved close collaboration with an industrial R&D team.  HPLC, GC, IC and colorimetric methods were used to monitor the progress of the wastewater treatments.

TEACHING EXPERIENCE
Teaching Assistant:  During my doctoral studies at the University of Western Ontario, I was involved on a twice weekly basis with laboratory courses for 2nd and 3rd year undergraduates.  The primary focus in the 2nd year course was on the synthesis of inorganic compounds, while the 3rd year course focused on analytical chemistry with students provided hands on experience with IC, HPLC, GC and AAS equipment supplied by Varian.  The experiments were geared towards the analysis of environmental samples and preparing students for careers in industry.

Postdoctoral Fellow:  During my postdoctoral studies in Canada, I gained considerable experience in working closely with 4th year undergraduates during the course of research projects.  The projects focused either on the synthesis and characterization of porphyrinoids and/or their paramagnetic anion and cation ?-radical species or on the analysis of the treatment of environmental contaminants, such as methyl tertiary butyl ether, in waste waters using H2O2 and UV light.
Assistant Professor:  During my time at Tohoku University, I prepared a complete set of lecture notes using Powerpoint for a 2nd year inorganic chemistry course for international exchange students using Shriver & Atkins as the textbook.  I delivered ten 90 minute lectures and set the examinations for the course.  I have also participated in a laboratory course designed to teach the basics of the synthesis and characterization of inorganic compounds to Japanese 2nd year undergraduates.  I have actively participated in weekly group seminars in Prof. Nagao Kobayashi’s laboratory in which 3rd and 4th year undergraduates and M.Sc. and Ph.D. students present their results.  I have gained considerable insight into how significant progress can be achieved in porphyrinoid research by carefully designing narrowly focused research projects for undergraduates, which can be completed in a relatively short timeframe.
