I completed my PhD in India, under the supervision of Supratim Sengupta at IISER Kolkata. In my PhD research, I showed a plausible pathway for the emergence of primitive cells at the Origin of Life, by developing mathematical models. After my PhD, I joined Umeå University as a Postdoc and started working in the groups of Peter Lind and Eric Libby. In my first postdoc, I worked on predicting antibiotic resistant mutations in Pseudomonas aeruginosa by combining a mathematical model of the gene regulatory network related to efflux pumps, genetic algorithm for parameter estimation, and evolutionary simulations. I showed the emergence of cross-resistance and collateral sensitivity between different antibiotics and identified effective sequential treatment strategies. During my first postdoc, I also co-developed a project with a peer postdoctoral researcher, where I analyzed RNA sequencing data from Arabidopsis thaliana roots under organic nitrogen (glutamine) treatment. I identified a key transcription factor that regulates root growth under glutamine treatment, by regulating one of the auxin biosynthesis pathways.

After finishing my Postdoc with Peter Lind and Eric Libby, I stayed in Umeå University with a new Postdoc position with Laura Carroll and Johan Henriksson. In my second Postdoc position, I will be developing novel methods for analysis of large scale single cell omics data, inspired by mathematical and systems biology.
