Undergrad project presentations on social polymorphism

Doaa Tehawey and Yara Ghnamah concluded their third-year projects and presented them today as posters! They both managed to finish and wrap up their analyses very nicely, in spite of covid19 challenges... Both projects were supervised by Aparna, and are part of her big project on the genomic basis of social polymorphism in Cataglyphis niger.

Doaa presented the analysis of 1000+ aggression assays between 30 nests sampled from the polymorphic population of C. niger in Tel Baruch beach, which includes monogyne colonies and a large polygyne supercolony. These behavioral assays will help us determine the social form of each sampled nest, to complement the genomic analyses.

Yara presented a phylogeny of mitochondrial haplotypes that she sequenced from the same 30 nests, which confirmed our working hypothesis that the monogyne an polygyne social forms are associated with distinct mitochondrial clades (in line with previous studies by Hefetz and colleagues).

These results will form the basis for ongoing genome-wide analyses from the same samples by Aparna.

 

Another NSF-BSF grant! - PhD/postdoc positions available!

Our lab received another NSF-BSF grant(!!!) in collaboration with the labs of Mickey Kosloff (at Haifa) and Juergen Liebig (at ASU).
We are recruiting Ph.D. student and postdoc:

NSF-BSF funded positions for a Ph.D. student and a postdoc are available in the University of Haifa, Israel. The students will work under the join supervision of Dr. Eyal Privman and Dr. Mickey Kosloff. The Privman lab studies evolutionary genomics of social behavior in ants, employing tools from population genomics, genomic mapping, and phylogenomics. Ongoing research includes several projects combining population sampling, behavioral experiments, chemical analysis of pheromones, genomic sequencing, and computational analysis (see http://privman.haifa.ac.il/). The Kosloff lab studies protein-protein interaction specificity in large protein families using computational protein structure and binding analyses at the atomic level, as well as redesigning and engineering proteins in vitro to modulate signaling networks. On going research projects focus on proteins that server as drug targets for the treatment of cancer, hypertension, and neurological (see http://koslofflab.haifa.ac.il/).
 
The new positions will be funded by an NSF-BSF grant for a collaboration with the group of Prof. Juergen Liebig at Arizona State University. The project aims to dissect the molecular basis for the evolution of olfactory recognition of chemical signals (pheromones) in ants. The Haifa-based teams will conduct evolutionary and structural analysis of hundreds of odorant receptors to prioritize candidates for experimental investigation by the ASU team. The study will entail sequencing and analysis of new genomes from multiple species. The successful candidates will participate in an interdisciplinary team and interact closely with the experimental investigators. The computational analyses will be conducted in Haifa, using our high-performance computer cluster. Therefore, candidates should have experience and/or motivation to learn bioinformatics, evolutionary and structural genomics.
 
The Faculty of Natural Sciences of University of Haifa offers a supportive, dynamic, diverse, multicultural and multilingual working environment. The Faculty hosts research groups working on a diverse, interdisciplinary spectrum of topics (see http://sciences.haifa.ac.il/sciwp/wordpress/page/4/). Students will have access to leading researchers with expertise in genomics and bioinformatics, molecular biology and evolution. Professional training opportunities in these fields are available in the University of Haifa and in other Israeli institutes, including advanced courses, workshops and conferences. Although the common language in Israel is Hebrew, there are many foreign researchers and students in the Faculty and all activities are conducted in English, including seminars, advanced courses, workshops and conferences. The Faculty offers state-of-the-art facilities and professional support for molecular biology research in general and genomics in particular, as well as a high-performance computer cluster for bioinformatic analysis.
Informal inquiries are also welcome.
The application should include a cover letter with a short description of research experience, research interests, and why you are interested to join our lab, your CV, and the contact details of 2-3 referees.
