Research Interests

Anders has a broad interest in understanding how different types of population dynamics and structure, combined with the effects of selection, mutation and recombination, shape the patterns of genetic variation observed in animal and human populations. A key complication with reconstructing the history of adaptation in a population is that neutral processes (such as bottlenecks and migration) can leave signatures in the genome that are very similar to those arising from natural selection. The key to distinguish between these two possibilities is to have a detailed and realistic reconstruction of past demography, which allows defining the neutral patterns, and thus the deviations that can only be explained by selection. Anders is developing individual-based spatially explicit models, informed by past climate, to reconstruct the demographic changes associated with the spread of humans out-of-Africa over the last 100k years, and is investigating selective responses to new environments and diseases encountered during this expansion. Such models are also important for reconstructing the number of expansions out of Africa, and for understanding the evolutionary relationship between humans and earlier hominins, such as the Neanderthal and Denisovan.
