About

I'm an undergrad student at the University of Canterbury, majoring in biological sciences. My favourite areas are ecology, satellite remote sensing, entomology, and astronomy. I’m currently working on a summer project to document lizard species on our campus.

I’ve been messing around with satellite imagery a bit for fun, you can get some really neat effects! This is a vegetation index from three Landsat-5 & 8 images taken thirty years apart stacked into a false colour composite, and it shows where the river has moved over time. I went on a trip to UC’s Cass Field Station for a mini bioblitz with folks from the school of biology, envirosoc, and biosoc. Our goal was to bring the Cass iNaturalist observations page to over 500 unique species, which we went well past. The landscapes were wonderful, and we saw some amazing creatures and flora. Went to a townhall meeting with Minister James Shaw today. It was great to hear about the government’s progress, some positive stories amid the general misery of climate issues, and what we still desperately need to do. Finally got around to processing images from a UC Physsoc field trip I went on to Mt. John observatory!
