1. Biodiversity and Species Extinctions in Model Food Webs
Abstract : Many of the earth’s ecosystems are experiencing large species losses due to human impacts such as habitat destruction and fragmentation, climate change, species invasions, pollution, and overfishing. Due to the complex interactions between species in food webs the extinction of one species could lead to a cascade of further extinctions and hence cause dramatic changes in species composition and ecosystem processes.

2. The response of model food webs to species loss : secondary extinctions and relaxation times
Abstract : Current destruction and fragmentation of natural habitats is predicted to cause great future losses in biodiversity (Pimm et al. 1995; Hughes et al. 1997; Sala et al. 2000). READ MORE

3. Computational topology optimization in continuum mechanics
Abstract : This dissertation concerns theoretical and computational methodologies in topology optimization in continuum mechanics.A general procedure for treating problems of this kind starts with the establishment of a well-posed continuum problem formulation, in the sense that one can prove existence of at least one solution to the problem.
