From Computational Biology Group
In a study initiated by Sébastien Jacquemont from the Service of Medical Genetics in collaboration with the group of Evan Eichler, we investigated the CNV burden of autistic patients and close relatives. We could show that females diagnosed with autism have on average more deleterious mutations in genes involved in neuro-developmental disorders than males, hinting that women can cope with a higher mutational burden than men. Moreover most of the deleterious mutations in genes important for brain function are transmitted by the non-affected mothers, showing that they can tolerate more mutations than the fathers. This study was published in the American Journal of Human Genetics and featured in the French newspaper Le Figaro
In collaboration with the group of Sophie Martin from DMF (UNIL), we developed Cellophane, an ImageJ plugin that semi-automatically quantifies fluorescent protein concentration profiles along the cell cortex. This plugin enabled the quantification of hundreds of profiles of two key regulators of the fission yeast cell cycle, Pom2 and Cdr2. The data analysis, along with other experimental evidence, showed that two important functions of Pom1, deciding when and where to divide, require distinct levels of Pom1. Lower Pom1 level are sufficient for division positioning, but higher levels are required to delay mitotic entry until the proper size is reached. The paper has been published in Cell Cycle .

Welcome to the Computational Biology Group!
The Computational Biology Group (CBG) is part of the Department of Medical Genetics at the University of Lausanne. We have interest in various fields related to Computational Biology, which are detailed in the Science section of this wiki. Briefly, there are two main directions: We develop and apply methods for the integrative analysis of large-scale biological and clinical data. This includes molecular phenotypes like gene-expression data, as well as organismal phenotypes (ranging from patient data to growth arrays). We focus particularly on relating these phenotypes to genotypes such as "Single Nucleotide Polymorphisms" (SNPs) and "Copy Number Variants" (CNVs) measured by microarrays or next-generation sequencing. Our goal is to move towards predictive models in order to improve the diagnosis, prevention and treatment of disease. A complementary direction of research pertains to relatively small genetic networks, whose components are well-known. We collaborate closely with experts of the field to identify biological systems that can be modeled quantitatively. Our goal in developing such models is not only to give an approximate description of system, but also to obtain a better understanding of its properties. For example, regulatory networks evolved to function reliably under ever-changing environmental conditions. This notion of robustness can guide computational analysis and provide constraints on models that complement those from direct measurements of the system's output.
In general, our group seeks an interdisciplinary approach, bridging the traditional gaps between physics, mathematics and biology. Our lab collaborates with experimental groups within and outside our department. In particular, due to our proximity to the University Hospital (CHUV) we have close contacts to medical research groups and assist the analysis of clinical data.
