Introduction
As an evolutionary ecologists my research interests are divided into three main areas. First, I am interested in understanding the adaptive evolution of marine organisms in response to extreme and changing climatic conditions. My Second area of interest is more applied to biodiversity conservation and management. Finally, I'm interested in sustainable aquaculture and bioprospecting, particularly from seaweed and marine invertebrates.

Article
Global changes can profoundly affect the sex determination and reproductive output of marine organisms, disrupting the population structure and ecosystems. High CO2 driven low pH in the context of ocean acidification (OA) has been shown to severely affect various calcifiers, but less is known about the extent to which low pH influences sex determin...
Article
Angraecum sesquipedale, also known as Darwin’s orchid, possesses an exceptionally long nectar spur. Charles Darwin predicted the orchid to be pollinated by a hawkmoth with a correspondingly long proboscis, later identified as Xanthopan praedicta. In this plant-pollinator interaction, the A. sesquipedale flower emits a complex blend of scent compoun...
Article
Feeding behavior is regulated by a complex network of endogenous neuropeptides. In chordates, this role is suggested to be under the control of diverse factors including thyrotropin-releasing hormone (TRH). However, whether this regulatory activity of TRH is functionally conserved in non-chordate metazoans, and to what extent this process is underp...

Environmental gradients can influence morpho-physiological and life-history differences in natural populations. It is unclear, however, to what extent such gradients can also modulate phenotypic differences in other organismal characteristics such as the structure and function of host-associated microbial communities. In this work, we addressed thi...

Pleistocene climatic oscillations caused periodic decline and rise of sea levels, leading to dispersion and retraction cycles of island flora. Yet, the role of island refugia in the current Sino-Japanese Floristic Region remains poorly understood. In this study, we investigated the population genetic structure of the widespread Sino-Japanese Floris...

Variation in nitrogen (N) availability significantly influences population dynamics and the productivity of marine phytoplankton. As N availability in the ocean is conditioned by the N source, it is important to understand the capacity of phytoplankton organisms to adjust their physiology and dynamics under different N conditions. We investigated t...

In the past decade Hong Kong’s live reef food fish trade (LRFFT) imported 200,000 tons of live fish for human consumption. The substantial demand for LRFF, worth over USD$ 2 billion, contributes to over-exploitation of tropical fish species. Here, we evaluate the temporal and species trends in Hong Kong’s LRFFT, testing potential associations with...

It is commonly known that phytoplankton have a pivotal role in marine biogeochemistry and ecosystems as carbon fixers and oxygen producers, but their response to deoxygenation has scarcely been studied. Nonetheless, in the major oceanic oxygen minimum zones (OMZs), all surface phytoplankton groups, regardless of size, disappear and are replaced by...

Approximately one-quarter of the CO2 emitted to the atmosphere annually from human activities is absorbed by the ocean, resulting in a reduction of seawater pH and shifts in seawater carbonate chemistry. This multi-decadal process, termed “anthropogenic ocean acidification” (OA), has been shown to have detrimental impacts on marine ecosystems. Rece...
