my Love and me

Fascinating nature, my love and me


Chih-hao Hsieh (Zac)

I am interested in statistics/theoretical ecology/zooplankton ecology/biological oceanography/fisheries.

I like simple ideas that have far-reaching implications and applications.

I am open to any cooperation, even beyond aquatic science, even beyond ecology.
