研究领域

Proteomics technologies had a remarkable impact on systems biology and biomedical research. For instance, mass spectrometry-based approaches now allow the large-scale mapping of protein-protein interaction networks, the quantification of proteins in different experimental conditions(e.g. normal and disease-related samples) and the identification of post-translationally modified proteins in complex biological samples (e.g. tissue or serum). The sensitivity and reproducibility of proteomics technologies are continuously increasing, thereby allowing the community to address biological questions never answered before. However, these improvements only translate into meaningful biological results when coupled with tailored computational analyses. Dr. Lavallée-Adam’s lab seeks to continuously adapt its computational research to emerging proteomics technologies and to produce innovative algorithms in order to generate novel high impact biomedical discoveries. Dr. Lavallée-Adam’s research yielded, among other things, software packages for the discovery and confidence assessment of protein-protein interactions and the analysis of the networks formed by these interactions. He also developed algorithms for the analysis of quantitative proteomics data obtained in different experimental conditions and the identification of intact proteins and large polypeptides using mass spectrometry. Finally, his lab’s most recent work aims to develop computational tools for the prediction of drug targets and off-target effects using large-scale mass spectrometry. The Lavallée-Adam Lab uses machine learning approaches, such as Bayesian inference, logistic regression classifiers and support vector machines, as well as sophisticated algorithm design and statistical analyses to answer complex biological questions. A significant portion of the lab’s work involves integrating large-scale genomics and proteomics data in order to derive novel biological knowledge about cellular mechanisms and disease processes. More specifically his lab currently aims to: Develop algorithms for the integration of quantitative proteomics datasets into protein-protein interaction networks to obtain a better understanding of cellular mechanisms. Design computational approaches for the identification of proteins and post-translational modifications in complex biological samples using mass spectrometry. Increasing the sensitivity of protein identification will help the characterization and provide a deeper understanding of the biological processes at work in such samples. Build software packages that identify high quality biomarker signatures and allow the discovery of novel drug targets for complex diseases through the integration of large-scale datasets and biological networks. These algorithms will provide better tools for diagnostic, prognostic, and therapeutic purposes. Ultimately, the main objective of the Lavallée-Adam Lab is to develop computational methods that will lead to a better understanding of cellular mechanisms and diseases processes. These approaches will push the boundary of proteomics applications in systems biology and clinical research. Most importantly, they will provide high quality biomarker signatures and will allow the discovery of novel drug targets for complex disease processes. The Lavallée-Adam Lab is currently actively recruiting researchers at all levels (undergraduate, graduate, and postdoctoral) with a background in computer science, bioinformatics, computational biology, statistics, or mathematics and an interest in biology and biochemistry problems.
