I study the impact of climate change on the large-scale atmospheric circulation and mesoscale atmospheric variability using a combination of theory, modeling and observations.

I am a postdoctoral researcher at Stanford's Doerr School of Sustainability where I am developing machine learning-driven emulators to represent sub-grid scale atmospheric variability in climate models. I am part of the DataWave program, which is an international consortium aimed at improving our understanding and representation of atmospheric gravity waves.

Prior to this, I worked at the Ludwig-Maximilian University of Munich (LMU), in collaboration with the German Aerospace Center (DLR), where I investigated the role of gravity waves in shaping the stratospheric circulation, a.k.a, the Brewer-Dobson circulation.

I received my Ph.D. from the Courant Institute of Mathematical Sciences, New York University, where my research focused on assessing stratosphere-troposphere dynamical coupling & tracer transport in idealized climate models, and implications of model transport biases for projections of the Antarctic ozone hole recovery.

    1. In June 2023, I delivered a set of four lectures on "Machine Learning Methods in Atmosphere, Ocean, and Climate Science" at an atmosphere, ocean, and climate science workshop organised at the International Centre for Theoretical Science, TIFR, Bengaluru. These lectures were aimed at introducing undergraduate, graduate and postgraduate researchers to machine learning (ML) methods. If you have wanted to explore the possibilities of ML in your research and would like to start somewhere, I would like to recommend these lectures specially prepared for this. The first lecture discusses the basics of ML, the second and third lectures are hands-on Python tutorials to code neural networks using PyTorch, and the fourth lecture discusses three novel use cases of ML in climate science: data-driven physical parameterizations, equation discovery, and weather forecasting.

    2. Humanity has a plastic problem. Conventional plastic manufacturing is still cheaper, but the greener alternatives, bioplastics in particular, are catching up fast. Here's a video that highlights some really innovative initiatives to manufacture bioplastics from Avocados, Sugarcanes, Mushrooms, and even Algae! Interestingly, the Sugarcane based bioplastic company featured in the video is based quite close to my hometown of Ghaziabad, India.

I wanted to check my gravity wave potential energy computations but couldn't find a reliable source online to compare the southern hemisphere climatology for N2.
