Research interests

My interest in ecological and biological statistics started before I began my PhD studies, resulting in my thesis “Spatial designs for field experiments”. Since then I have accumulated a lot of design experience through consulting work for Ecology and Marine Sciences postgraduate students and staff.

Experimental data often involve missing and/or dependent values, even with perfectly planned designs. In this case, standard statistical methods should not be applied. My research focus has been to plan appropriate designs and develop methodology to handle messy and incomplete data.

In 2009, I revisited Prof A Chao in Taiwan to further learn and develop computer software and use it to find species richness in a single community as well as shared species in two or more communities. Currently I am developing and apply these methods further to assess the quantity and similarity of species richness.
