MaSHBackground, coordinators and main contacts
MaSH has evolved from a group of University of Auckland-based researchers who are passionate about the application of mass spectrometry techniques to a wide range of scientific research. For several years this group has linked researchers together to discuss mass spectrometry techniques and troubleshoot technical challenges. We have partnered with the Centre for eResearch to create MaSH to draw together researchers from across the university to develop a mass spectrometry knowledge base and data analysis capability while fostering interdisciplinary collaboration. We acknowledge the support of the University of Auckland Strategic Research Initiatives Fund for support of MaSH.
To develop an outstanding technical and research support environment to increase the effective impact of University of Auckland mass spectrometry-based research
Instrument Grant Coordinator
Gus is a Senior Research Fellow in the Department of Physiology, and the director of the Biomedical Imaging Research Unit. His research interests lie primarily in vision science, where as part of the New Zealand National Eye Centre he utilises imaging mass spectrometry to study the structure and function of the ocular lens. He also has research interests in neurodegeneration through a collaboration with the Centre for Brain Research.
Martin is responsible for the operation of the School of Biological Sciences Mass Spectrometry Facility (3x LC-MS/MS instruments, 3x GC-MS instruments) housed in the Science Centre (Buildings 301 and 302). His main areas of interest and expertise lie in LC-MS/MS analysis of peptides, proteins, drugs, small molecules and lipids. Current areas of ongoing activity are the characterisation of modifications to specific proteins, global quantitative proteomics (SWATH), and the profiling of small molecules and secondary metabolites in complex samples.
Eric is the Technical Services Manager of the Liggins Institute and oversees the three mass spectrometers (two LC-MS/MS instruments and a Q-Exactive) in the Liggins research lab. He has a background in HPLC and small molecule analysis. His expertise is in developing targeted methods for specific groups of compounds by LC-MS/MS with a particular focus on steroid quantitation across a variety of matrices. He has assisted many Ph.D students to learn the wonders of mass spectrometry as an analytical tool and promotes the importance of this technique across the University.
Yongchuan is a Senior Research Fellow in the Auckland Cancer Society Research Centre. His research interest mainly lies in charaterisation of the DMPK and predictive biomarkers in drug discovery. He also has deep understanding of varieties of bioanalytical techniques, tissue culture and animal models used in biomedical research. His expertise in the applications of LC-MS/MS on small molecules and targeted proteomics will help the researchers to develop robust methods for their projects.
George is a Research Fellow in the Department of Physiology. He is focusing on computer programing for quantitative proteomics/metabolomics research. He has adaptive computer scripting strategies to provide highly efficient, robust ‘omics data solutions. He is willing to share his ‘omics experience and provide data analysis support on behalf of the MaSH.
Erica Zarate is the Senior Technologist of the GC-MS part of the Mass Spectrometry Facility at the School of Biological sciences. She holds a MSc (Biological Sciences) and a PhD (Biological Sciences) in lipid and fatty acid analysis of sea urchin gonads using the GC-MS from the University of Auckland. She has been working with GC-MS since 2010 during her PhD. Prior to her PhD, Erica worked as Research Technician in the Marine Lab at the University of Auckland managing the research laboratory, performing biochemical analysis and using the TLC-FID. Erica provides technologist support for metabolomics analysis, sample preparation, calibration and maintenance of GC-MS and GC-MS data processing at the School of Biological Sciences, University of Auckland, New Zealand.
Kyriakos is a Research Fellow in the Department of Physiology. He has extensive experience in HPLC and LC-MS/MS of small molecules ,peptides and proteins. He is willing to share his experience and provide support on behalf of the MaSH for a range of projects including but not limited to sample preparation of proteins, analysis of extracts and fractions of natural products, peptide purification and characterization, etc.
Liz is an Honorary Research Fellow in the School of Medical Sciences. Her research interests lie in the use of volatile biomarkers as diagnostic and investigative tools (volatilomics), where she applies gas chromatography-mass spectrometry (GC-MS) coupled with solid phase microextraction/thermal desorption to study milk, plasma/serum, faeces, skin and urine. She has several volatilomic project collaborations internally, as well as with North Shore Hospital and Auckland University of Technology (AUT). Currently she is investigating the role of symbiotic fungi and yeast in the metabolism of fatty acids in the human gut, using both SPME GC-MS and imaging mass spectrometry (MALDI-ToF-MS). She also has an interest in optimisation of untargeted data extraction and curation for mass spectrometry-based metabolomics and has a collaboration with the Department of Statistics developing statistical methods for detection of metabolite dysregulation.
Nicholas is a Research Fellow in the School of Biological Sciences, and is the responsible for the operation of the Bruker SolariX XR 7T Fourier transform-ion cyclotron resonance mass spectrometer. His research interests stem from his passion for ion chemistry and mass spectrometry, and include advancing top-down mass spectrometry of macromolecular complexes for structural biology, interogating reaction intermediates through novel ionization sources, and characterizing surfaces and thin-layer materials.
