As a modeler, my work involves leveraging mathematical and computational tools to simulate complex ecological processes, providing valuable insights for understanding ecosystem dynamics, predicting the future of the system under current climate changing scenarios, and informing decision-making for sustainable resource management. Some of my current research activities include:

 

Nitrogen Fixation:

I develop cell-based models to understand the mechanisms of nitrogen fixation by various aquatic microorganisms. My models are able to assess the impact of different environmental factors on nitrogen fixation rates, and their contribution to total nitrogen fixation rate. I have previously developed a model focusing on heterotrophic nitrogen fixers associated with sinking marine particles (Link), and I am continuing to investigate their activity. Currently, I am studying UCYN-A, another nitrogen fixer. Additionally, I am involved in research on Trichodesmium (Link).

 

Coral Systems:

I use modeling techniques to simulate the dynamic interactions within coral reef ecosystems, incorporating factors such as temperature fluctuations, ocean acidification, and species composition. I generate insights into the resilience of coral communities to environmental stressors and guiding conservation efforts.

 

Phytoplankton Dynamics:

I apply mathematical models to characterize the population dynamics of phytoplankton in response to changing environmental conditions, including nutrient availability, light intensity, and oceanographic currents. I integrate experimental data and field observations to validate model outputs and improve predictions of phytoplankton blooms and carbon fluxes in marine ecosystems.

 

I am also specialized in researching the trophic strategies of plankton (Link). My work includes developing cell-based models to explore how plankton size influences their trophic behavior (Link). Additionally, I investigate the impact of environmental conditions on these strategies and examine their effects on ecosystem functions across different latitudinal gradients (Link).

 

Harmful Algal Blooms:

I develop cell-based models to simulate the initiation, growth, and dispersion of harmful algal blooms, considering factors such as nutrient loading, hydrodynamics, and toxin production. My modeling frameworks can be used to assess the effectiveness of management strategies, such as nutrient reduction policies, in mitigating the impacts of algal blooms on aquatic ecosystems and human health.
