Python

I mainly use Python with the scientific stack of libraries (e.g., Numpy, xarray, Pandas, Matplotlib, Jupyter, Dask).

Here is a course I created on High Performance Python. It includes profiling, vectorisation with NumPy, compiling with Numba, parallelisation with Dask and Ray, and using GPUs with JAX and CUDA/Numba.

Numerical atmospheric models

I taught and provided support for a complex air quality model, WRFChem (Bash and Fortran).

Machine learning

I used machine learning models to predict optimum emission reduction strategies to improve air quality and public health in China. These were Gaussian process emulators trained from ~20 TB of simulated data from numerical atmospheric models.

I provided training for these emulators video (Colab, slides, and GitHub).

Here is a course I created on an Introduction to Machine Learning. It covers fundamentals, machine learning with scikit-learn, deep learning with TensorFlow / Keras and PyTorch / PyTorch Lightning, data pipelines, model tuning, transfer learning, and distributed training.

Useful learning resources

Here are some great learning resources for topics in data science, software engineering, and machine learning that I’ve found helpful.
