Organisms have to deal with many kinds of costs, but dissecting and quantifying each of them, and how they affect adaptation and evolution, is tricky. This is especially true when some costs are "internal" (e.g., due to deleterious mutations) and some are "external" (environmental). In a study led by former postdoc Laasya Samhita (now Assistant...

Founders shape long term population fate
The first set of findings from our long-term beetle populations are now out! In a massive effort, collating data across over 5 years, Vrinda and other lab members monitored flour beetle populations exposed to a new, poor habitat — corn flour — instead of the optimal ancestral wheat flour. While we expected some extinction, nearly all... Continue Reading →
Open position: Postdoctoral fellow
We are looking to recruit a Postdoctoral Fellow with a start date of February or March 2025. The position is for a minimum of 2 years (extendable for up to 4 years), supported by an ongoing grant from the DBT/Wellcome Trust India Alliance to study the evolutionary effects of mutation bias. Salary and benefits will... Continue Reading →
Symposium Section in the American Naturalist
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 →
New paper: Mutation bias shifts can be adaptive
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 →
