Hannes Röst

Hannes Röst obtained a BSc in Biochemistry and a MSc in Bioinformatics from ETH Zurich, and during his PhD in the lab of Prof. Ruedi Aebersold at ETH Zurich, he developed novel computational methods to analyze mass spectrometry-based proteomics data. This work has allowed researchers to increase throughput of targeted proteomics experiments by up to 100-fold and increase the number of samples that could be analyzed in a single study. After his PhD, he joined the lab of Prof. Mike Snyder at Stanford University to apply his work in the area of personalized medicine. In Stanford, Hannes focused on developing computational tools for handling, managing and analyzing large, heterogeneous and longitudinal datasets. His research at University of Toronto explore the capability novel mass spectrometric methods to obtain highly quantitative proteomics and metabolomics data matrices and use these quantitative data to address questions in systems biology and personalized medicine.

Dr. Olga Zaslaver

Olga Zaslaver obtained a BSc in Biomedical Science from York University in Toronto, and a PhD from the department of Molecular Genetics at the University of Toronto. Olga's PhD work investigated the origin of two poorly described metabolites in budding yeast, the oncometabolite 2-hydroxyglutarate and the fermentation product citramalate. She uncovered the enzymes responsible for 2-hydroxyglutarate metabolism and described its compartmentalization within cells using high resolution LC-MS, stable isotope tracing and genetics. She also connected the industrially relevant compound citramalate to leucine and threonine metabolism in yeast. Since 2016, Olga has been investigating the metabolic fingerprint of patient-derived glioblastoma stem cell lines through her work with Stand Up To Cancer. Olga continues to use high-throughput LC-MS technology to understand the dynamics and variation in cell metabolism and its implications for health and disease.

Dr. Andrew Quaile

Andrew Quaile obtained his BSc and Ph.D. at the University of Liverpool, UK. After this, he came to Canada to start his postdoctoral research in the Raught lab at UHN, where he used mass spectrometry to explore the protein interactions of the yeast ubiquitination system. This led to his joining the Savchenko lab at U of T, where he combined AP-MS and proteomics with structural, functional and biochemical data to study a class of bacterial virulence proteins called ‘effectors’.

Most recently, Andrew worked for an industry CRO where he was designing and validating GMP/GLP bioanalytical mass spectrometry methods to support preclinical toxicological studies as well as other methods for their pharmaceutical industry clients. These methods spanned various small molecules, metabolites, peptides and proteins in a broad range of chemical and biological matrices.

He joins the lab to support our metabolomics capabilities as well as to help develop and optimise new methods using our research and emerging technologies.
