Research
I use mathematical and computational models to understand and predict the dynamics of complex aquatic ecosystems. My research combines theoretical ecology, biological oceanography, and biogeochemistry to investigate processes ranging from microbial physiology to ecosystem functioning and global nutrient cycling. I integrate field observations and experimental data with mechanistic models to improve predictions of ecosystem responses to environmental change.
Student and Research Opportunities
I welcome inquiries from motivated students and early-career researchers interested in mathematical modeling, theoretical ecology, marine ecology, and biogeochemistry.
Bachelor's and Master's Projects
I offer thesis projects on topics including plankton ecology, nitrogen fixation, harmful algal blooms, coral reef ecosystems, climate change, and marine biogeochemistry. See my Research page for more details. Projects may involve mathematical modeling, numerical simulations, and data analysis.
PhD and Postdoctoral Opportunities
I am happy to discuss potential PhD and postdoctoral projects aligned with my research. I also welcome prospective candidates interested in applying for external fellowships and can provide guidance in developing competitive research proposals.
If you are interested in working with me, please send me an email with a brief description of your research interests and your CV.
