Anastasios Tsaousis’ research is focused on investigating the adaptations of microbial eukaryotic (protists) organisms. His laboratory is combining detailed bioinformatics analyses of newly generated genomic/transcriptomic/metabolomic results with field, cell biological and biochemical methods to investigate the parasitic and free-living microbial eukaryotes living in diverse and extreme environments.

About the authors

Kevin McKinley PhD Candidate, School of Applied Sciences, Edinburgh Napier University, Sighthill Campus, Edinburgh EH11 4BN, UK

s.rueckert@napier.ac.uk @SonjaRueckert

Sonja Rueckert is Associate Professor in Marine Biology/Parasitology at Edinburgh Napier University in Scotland. Her research is focused on the morphology, diversity, phylogeny, biology, ecology and evolution of eukaryotic microbes, with a focus on the gregarine apicomplexans. Understanding the symbiotic relationships with their hosts is one of her main goals. What advice would you give to anyone starting their academic career? Kevin: Don’t hide from the rest of the academic community. Discuss potential ideas with your supervisors and your colleagues. Go to academic conferences and seminars, and reach out to those who you think may aid in your research. We can learn a lot from colleagues in parallel fields. Could you describe one of your typical workdays? Kevin: My workload contains a mixture of field-based and lab-based work. One day I could be in the field, kick-sampling in a river to collect amphipods that I’d later examine for gregarine infection. Another day could be spent in the lab growing and maintaining cell lines that I aim to infect with gregarines.
