In 2022, Deepa organized the ASN Vice-Presidential Symposium at the annual meeting of the Evolution societies in Cleveland, Ohio, USA. The symposium featured a set of wonderful talks by five invited speakers from across the world, analysing how genetic variation shapes adaptation. The work reported in these talks is now out in the Symposium section... Continue Reading →
We're very happy to welcome Shazia Parveen, who worked with us as a JRF for some time and has now formally joined the lab as a PhD student. Shazia has a Bachelor's degree in Biotechnology from Jamia Millia Islamia New Delhi, and an MSc in Molecular Medical Microbiology from IIT Kharagpur. She is interested in using... Continue Reading →
Happy to announce that applications are now open for the next Bangalore school on population genetics and evolution from 12–23 Feb, 2024. We welcome PhD students and postdocs interested in evolutionary biology, from India as well as other Asian and African countries. There are no participation fees, and we have some travel support for international... Continue Reading →
Several years ago, Arun Prakash and Imroze Khan set up an ambitious experimental evolution study in the lab, infecting populations of flour beetles with the pathogen Bacillus thuringiensis (Bt). They found that different selection regimes led to the evolution of mutually exclusive immune responses – beetles either evolved better basal resistance to Bt, or immune priming... Continue Reading →
Our paper describing the evolutionary effects of shifts in mutation bias is now published! We started out by asking if mutation spectrum could alter the fitness effects of new mutations in E. coli. To our surprise, we found a consistent effect across many environments, but could not attribute the difference to any particular properties of... Continue Reading →
Our long-dreamt-of project on understanding the effects of widely varying tRNA gene copy number is finally complete! In a new paper, we describe the growth consequences of altering redundancy in the bacterial translation machinery. We find that the costs and benefits of redundancy vary with the possible growth rate, i.e. it is nutrient-driven. This was... Continue Reading →
We are starting 2023 on a great footing, with a new paper reporting a lot of really nice work by Vrinda and Gaurav. For a long time we have been puzzled by seemingly maladaptive oviposition behaviours of female flour beetles faced with different resource options. By carefully manipulating egg allocation across resource patches, we were... Continue Reading →
Former postdoctoral fellow Rittik Deb has joined the National Institute of Science Education and Research (NISER) Bhubaneswar as an Assistant Professor. Congratulations Rittik, and we look forward to all of the exciting discoveries that you and your group will make in the coming years!
