Profile
I have a BSc in Biology (University of the Philippines Cebu, 2009) and an MEng degree in Marine Environmental Engineering (MMU, South Korea, 2012). My primary research interest is the ecophysiology of phytoplankton; particularly,  how their functional role as primary producers in the aquatic food web and as regulators in biogeochemical cycle are influenced by the varying environmental factors, e.g.  light quality, nutrient availability, vertical mixing and stratification, and predation.

In my Master’s thesis, I investigated the dynamics of phytoplankton photophysiology and primary productivity in an altered river estuary in a temperate region over an annual cycle using instantaneous and in situ measurements using Fast Repetition Rate Fluorometry (FRRF). I also identified factors that influence the variability of photophysiological variables and primary productivity in a turbid river estuary. My recent research works include the pattern of phytoplankton community structure in coastal areas affected by anthropogenic activities, i.e. water pollution and oil contamination.

PhD title: The interactions of multiple environmental stressors and their influence on the physiology and ecology of harmful bloom forming algae
I will investigate how synergistic and antagonistic interaction of multiple climate change stressors (i.e. warming, ocean acidifications, eutrophication etc) can influence the ecophysiological and evolutionary responses of HAB-forming phytoplankton under the supervision of Dr Etienne Low-Decarie (University of Essex). I will conduct laboratory experiments to investigate the photosynthesis, food uptake, and growth of bloom forming phytoplankton in different growth conditions. Experimental evolution will be employed as the approach to investigate whether phytoplankton can evolve over a few hundred generations in response to specific environmental drivers and to quantify the fitness gain and changes in traits of the evolved populations. Individual and combined effects of the changes in environmental variables on the phytoplankton ecophysiology, clonal and genetic diversity will be carried out to investigate synergistic and antagonistic interactions of these stressors. Lastly, through experimental and modelling techniques, a new model will be developed to predict how climate-driven genotypic and phenotypic changes in the phytoplankton community structure affect its role to provide food to organisms at the higher trophic level.
