Studied how seasonal resource peaks influence population dynamics, competition and phenological adaptation among pollinators. By studying the temporal aspects of the pollinator environment he hoped to provide new perspectives on how climate change and pesticide use influence diversity of pollinators and the ecosystem services they provide.

As a theoretical ecologist, Jacob's main tool for research is mathematical modelling, especially life-history optimisation, population dynamic modelling and adaptive dynamics.
