About Me

  • Hi! I’m a researcher passionate about tackling tough challenges in everything from renewable energy to cutting-edge tech. I’m especially interested in designing measurement systems and analysis techniques that allow us to acquire and process data in ways we couldn’t before—finding new ways to pull more insights about the physical world. Originally from India, I grew up in the UK, studied Physics at Bristol, and have nearly completed my PhD at Oxford. I’m also interested in making science more accessible, especially for students from disadvantaged backgrounds—I know how much that support can matter! When I’m not in the lab, you can find me sketching with pencils, pens, or watercolours (still very much an amateur!).

📚 My Research

My research focuses on the measurement and analysis of perovskite solar cells, with a particular emphasis on using advanced spectroscopy techniques to gain insights into device performance and degradation. I specialize in developing innovative approaches for data acquisition, enabling a deeper understanding of the fundamental processes that govern the behaviour of perovskite materials.

Using my strong expertise in spectroscopy, optical modelling and drift-diffusion simulations, and Bayesian inference, I work to quantify key parameters such as charge collection efficiency, material heterogeneity, and recombination processes. I design and build custom measurement systems to acquire high-quality data, and leverage my coding skills to run simulations that complement experimental results.

By combining detailed experimental analysis with modelling, my goal is to provide a clearer understanding of the limits and potential of perovskite solar cells, offering valuable insights that can guide future research and development in the field.
