Alyssa Pyke has comprehensive experience as a public health virologist. Her work has supported Queensland Health responses to numerous outbreaks caused by pathogenic arthropod-borne viruses such as Japanese encephalitis virus and dengue virus. She obtained her PhD in molecular virology after developing an infectious Ross River virus clone. She has worked extensively in high level containment facilities and managed a Physical Containment Level 4 (PC4) laboratory.
In her current role as a supervising senior research scientist, she is primarily involved in the surveillance, isolation and characterisation of viruses of public health significance. She has designed and introduced numerous molecular assays essential for human diagnostics and mosquito vector competence studies. She has also developed synthetic recombinant proteins for Hendra virus and Zika virus which have provided enhanced capabilities for serological diagnostics.
Alyssa is particularly interested in the emergence and evolution of arthropod-borne viruses and their phylogenetic relationships. She utilises whole genome sequencing for advancing surveillance platforms and providing insights into molecular epidemiology. Her research and investigation of exotic and endemic pathogens, such as Zika, dengue, chikungunya and Ross River viruses, includes the discovery and characterisation of two rare and highly divergent dengue viruses.
