Arutchelvan Rajamanikam
Arutchelvan began his research in parasitology during his postgraduate studies at Universiti Malaya, Malaysia, focusing on the protozoan Blastocystis spp. and its associated bacterial communities. His work has spanned drug resistance, drug discovery, and metagenomic analyses relevant to Blastocystis spp. In recent years, he has broadened his research to include emerging pathogens such as free-living amoebae, Entamoeba histolytica, and diverse bacteria, with an emphasis on exploring host–microbe interactions at the genomic level.
Mark Viney
Mark started studying parasitology as a student at Imperial College, London before doing a PhD at the Liverpool School of Tropical Medicine, studying Strongyloides infection in people and other animals in the island of New Guinea. Since then he has continued to work on the biology and genetics of Strongyloides and parasite eco-immunology at the Universities of Edinburgh, Bristol and Liverpool, in the UK.
