David Gilljam

I’m an ecologist with a background in computer engineering that have found my perfect scientific niche within the field of theoretical ecology. I have a broad interest in the ecological and evolutionary processes that governs the ‘tangled bank’ and underpins the ‘balance of nature’ in natural ecosystems. My research focuses on the effects of environmental variation and within and between species interactions on the dynamics, stability and functioning of ecological networks. To gain a detailed, mechanistic and applied understanding, I use study systems where theoretical and experimental approaches can be combined to investigate the effects of, for example, climate change on the ecology and evolution of fish communities and insect-natural enemy dynamics and interactions.
