I am a researcher with a strong interest in the Earth’s climate and oceans.
I began my foray into the ocean from afar (remote sensing), and have now transitioned into its physics and biogeochemistry (ocean modeling),
primarily working on marine heatwaves and marine biogeochemical extremes at the surface and subsurface.
I am attributing the drivers of Marine Heatwaves and Ocean Acidity Extremes in the Southern Ocean, utilising the Regional Ocean Modeling System (ROMS). Concurrently, I am superivising a master's project on the biological impacts of marine heatwaves.
Developed the concept of Column-Compound Extremes - where marine heatwaves and biogeochemical extremes co-occur in the vertical water column. I then applied this to the Southern Ocean and Antarctic Marine Protected Areas, where such extremes have been increasingly co-occurred.
Developed ocean colour inversion algorithms for multi and hyper spectral sensors. Established a proxy method to measure backscattering in highly turbid waters. Conducted regular ship-based measurements of optical water properties.
Enhanced a radar propagation model by incorporating ray trapping in the boundary layer.

Growing up in Singapore, my native language is English. I am thus proficient in speaking and writing in English. I also get by with a functional knowledge of Mandarin, and German which I picked up in Switzerland.

Outside of work I enjoy hiking, climbing, skiing, and camping. When I have the opportunity to travel, I enjoy experiencing nature, history, and culture.
