Dr Juliana Yeung is a scientist with expertise in protein science, microbiology, molecular biology and biochemistry in methanogens (Archaea) and filamentous fungi. Juliana is an AgResearch employee seconded to Lucidome Bio. At Lucidome Bio, she uses her knowledge and experience to lead vaccine target validation. Juliana received her PhD in Biological Science from Simon Fraser University (Canada), was a recipient of the Natural Sciences and Engineering Council of Canada Postgraduate Doctoral Scholarship and the Australia Awards Endeavour Research Fellowship, where she researched a collection of soluble and transmembrane proteins to study sialic acid metabolism of the opportunistic pathogen, Aspergillus fumigatus. She later completed her postdoctoral research work at AgResearch in the Animal Health department to further develop her specialty in protein science by utilizing 1D/ 2D electrophoresis and LC-MS/MS for antigen discovery and confirmation, and extraction of antibodies derived from various ovine and bovine sources in an animal vaccine program. Juliana later accepted a permanent scientist position at AgResearch where she utilizes her specialty in protein science to study antibody binding to native membrane proteins for vaccine development.
