Data Scientist · notes on forecasting, geospatial analysis & Python tooling
I'm Victor — a data scientist writing up the things I learn along the way: time series forecasting, geospatial analysis, and the Python tooling that makes it all less painful. Before this, I did climate & atmospheric science research (Ph.D. @ CUHK, postdoc @ MIT) — that work now lives on my academic archive.
