Le Wei

I am an early-career epidemiologist with a strong publication record, recognized for developing innovative research ideas and delivering high-quality outputs through both independent work and collaboration. My doctoral research assessed the metrics that reflect physical activity intensity and investigated the independent and joint associations of different physical activity dimensions (intensity, volume, type, context) with chronic disease and mortality outcomes. I have extensive experience working with large datasets, applying advanced statistical methods, and visualizing complex results.

I am a detail-oriented and highly motivated researcher. I am now seeking a post-doctoral position where I can build on my expertise and contribute to high-impact research in physical activity epidemiology.
