Interview Yoav was interviewed in Makademia (Radio show) on his work. In the fascinating interview (in Hebrew). He talked about brain, evolution and human cognition.

farewell We all say goodbye to Fouad Zahdeh who submitted his PhD thesis. Fouad worked on the genetic basis of Mendelian diseases, as well as on NMD and codon usage bias. He joined the research group of Ephrat Levy-Lahad in the Medical Genetics Institute in Shaare Zedek Medical Center as a bioinformatician.

Research Interests:
Our lab deals with a host of topics in the general fields of molecular evolution and genetics. Among the topics that are currently actively pursued are:
  • Recent human evolution. Recent advances in ancient DNA sequencing yielded complete high-coverage genomes of the Neandertal and the Denisovan. We devise algorithms that predict the DNA methylation along ancient DNA, and identifies genes that are differently activated in present-day humans.
  • Gene architecture. We study conservation of gene architecture by means of intronic positional conservation. This is an extension of the more "standard" sequence and structure evolutionary conservation modes. We are interested in the quantification of this conservation, and in studying its implication on our understanding of intronic functions.
    We also study the evolutionary forces that have led to the wealth of gene architectures seen across the eukaryotic domain. This includes the identification of evolutionary trends, and the study of mechanisms of intron gain and loss.
  • Splicing. We study the functional roles of splicing in general, and of alternative splicing in particular. We develop a tool to estimate the effect of splicing on normal splicing patterns, and its connection to human diseases.
  • Massive parallel sequencing. We are involved in a number of projects that involve the analysis of next-generation sequencing data. Among these are identifying human disease-causing mutations, and studying the mutational spectrum of meiosis in yeast. We mainly use resequencing and RNA-seq analysis.
  • Nonsense mediated decay (NMD). We are interested in the mechanism that recognizes a premature termination codon in mammals, and its relationship with introns in the 3'UTR.
  • Phylogenetics. We are interested in various aspects of rooting phylogenetic trees.
  • Systems biology. We characterize the dynamics of gene architecture in individual genes, and are interested in studying the connections between this dynamics and other genic features.
  • Multivariate data analysis. My lab is also active in some fields of applied mathematics: multivariate analysis, statistical pattern recognition, data visualization, and machine learning.

Our Web Servers
Movie Gene ORGANizer connects genes to body organs and body system. Given a list of genes, Gene ORGANizer finds body organs in which these genes are enriched or depleted. The web server is still under development, and not published yet, but it is already open for use by the community.

Movie JuncDB is a gene exon-intron architecture comparative database, covering nearly 40,000 sets of orthologous transcripts across 88 eukaryotic species. Accepted for publication at the upcoming database issue of Nucleic Acids Research, see online version.
