How do species adapt to the changing environment? Why do some populations persist through adverse conditions or genetic bottlenecks better than others? I am interested in studying how fishing pressure and the changing environment may affect the dynamics of fish populations and the evolution of fishes in both marine and aquatic ecosystems. In my doctoral dissertation, I study the fish populations in Finnish lakes, and investigate the interplay between life-histories, populations, and ecosystems, and how changes in those may affect fish population resilience.

During my M.Sci.  degree at the University of Glasgow, Scotland, I studied the habitat requirements of Atlantic cod (Gadus morhua) juveniles on the west coast of Scotland. In this work, we tested the use of diver operated stereo-video cameras in studying juvenile fish habitats in relatively shallow coastal waters. See Elliott et al. 2016 (doi:10.1111/jfb.12998).

As part of my M.Sci. degree I visited the Hawai'i Institute of Marine Biology to study the phylogeography of Indo-Pacific sister wrasses the Yellowtail coris (Coris gaimard) and the African coris (C. cuvieri). I used mitochondrial and nuclear markers to reveal the population structure and demographic history of these reef fishes. See Ahti et al. 2016 (doi:10.1111/jbi.12712).

Additionally, I have an extensive background in SCUBA diving with 4000+ logged dives, AAUS scientific diver qualification and experience in both open and closed circuit. I have conducted fieldwork in vastly different conditions from the Baltic Sea to Madagascar, and from Christmas Island to Red Sea and Hawaii.
