Teaching interests

My teaching interests are aligned with my research interests in analytical and organic chemistry, mass spectrometry, and organic geochemistry. I teach on the following modules on the BSc Chemistry CHM3015 - Advanced Organic Chemistry (Module leader) CHM2012 - Organic Chemistry (Module leader) CHM3013 - Advanced Analytical Chemistry (Molecular spectroscopy) CHM2016, CHM3011 (Project modules) I also teach on the MSc / MChem Analytical Chemistry CHM5004 CHM5005 GEES514 Finally, I lecture and supervise practicals for the Foundation courses: CHM009 Chemistry

Research interests

My research topics have developed out of a strong interest in analytical techniques for detection of biomarkers / polar molecules and microbial ecology / biogeochemistry. I worked on Archaea (production and biodegradation of lipids) in sediments, on products of microbial biodegradation of oil, on polar compounds (sterols) in sponges and fossil concretions. Now, I am working on a way to enable the determination of the stable isotopic composition of large, polar biomarkers for the methane cycle. For my research, I use highly developed analytical methods such as HPLC-ESI-MSn, GC-IRMS, GCxGC-TOFMS and GC-IRMS. I am also very interested in the use of advanced data processing and statistical methods for geochemistry, in order to investigate patterns of naturally produced and anthropogenic compounds in the environment, and to compare recent organisms or samples with fossil biomarker distributions.
