PhD, Docent, Principal Investigator
Ayman Khattab is a University researcher with over 15 years of experience in malaria research. Ayman obtained his PhD in 2003 from the University of Tübingen, Germany. He conducted his PhD work at the Institute for Tropical Medicine, University of Tübingen and the Albert Schweitzer Hospital, Lambaréné, Gabon where he studied the pathogenesis of placental malaria. In late-2003, Ayman started his post-doctoral work at Bernhard Nocht Institute for Tropical Medicine in Hamburg. He continued his research on placental malaria and PfEMP-1. He also expanded his research to cover other parasite surface antigens such as RIFINs and STEVORs, their expression in various stages of the parasites, their function and role in pathogenesis, and in the acquired immunity in individuals from malaria-endemic areas.
In July 2007, Ayman joined the Haartman Institute, University of Helsinki, to set up a malaria research lab. The lab maintains the malaria parasite, P. falciparum cultures and Anopheles mosquito colonies to study malaria pathogenesis and to develop novel interventions for the control of malaria transmission.
Specifically, Ayman focusses his research on 1) The surface antigens of P. falciparum as virulence factors 2) Complement escape by the P. falciparum parasite 3) The immune interaction between mosquitoes and the human host and 4) Mosquito control.
PhD
Juha graduated as a PhD in biomedical sciences at the University of Leiden, the Netherlands in 2017. During this time, he was an early stage researcher (ESR) in a Marie-Curie Sklodowska Initial Training Consortium called TransVIR. The consortium, its research, and training focused on immunology and vascular inflammation, with a broad range of disciplines and the involvement of industrial and academic partners. His project was a joint venture between Hycult Biotech and the department of nephrology at the Leiden University Medical Center. The project focused on the development of a methodology that would allow complement system monitoring in experimental rodent models. The methodology was applied to various renal disease and injury models, validated and transferred to the industrial partner for future commercialization.
Before joining the Complement group, Juha worked in various research positions that have broadly revolved around assay, reagent and method development. He has held positions in two start-up companies, worked a few years as an application scientist after his Master's thesis, and spent another few years in Ireland as a senior scientist after the research phase of his PhD studies was complete.
His current projects are focused on studying different aspects of the complement system in relation to pathogenic microbes. One aspect is to better understand the bacterial reaction to complement injury, and others are focused on understanding the complement evasion mechanisms of various pathogens and their potential diagnostic or vaccine targets.
