Head, Clinical Immunology Lab
Professor Stephen Kent trained as an infectious diseases physician and viral immunologist in Melbourne and the USA. He is a National Health and Medical Research Council Senior Principal Research Fellow. Several vaccine concepts tested in his lab have shown sufficient promise to progress into human clinical trials. Stephen remains active in infectious diseases clinical medicine at the Alfred Hospital and Melbourne Sexual Health Centre. He is proud to lead a team of gifted scientists studying viral immunity.
Head, Humoral Immunity Lab
Adam has a long standing interest in understanding the development and regulation of humoral immunity to vaccines and viral infections. After a PhD at the University of Melbourne, and post-doctoral training at the Vaccine Research Center, NIH, he returned to the Doherty Institute in 2015. His team are actively researching antibody and B cell immunobiology, in particular mechanisms that might inform the development of broad and lasting vaccine-elicited protection against influenza or SARS-CoV-2.
Head, Antiviral T cell Lab
Jennifer is a mid career researcher with a strong interest in non-conventional and CD4 T cell immunology in the context of infectious disease. She completed her PhD in HIV immunology in 2014 at the University of Manitoba, Canada, followed by a fellowship at the Public Health Agency of Canada. In 2016, she moved to Melbourne and has established a team to study the role for T cells in modulating protective immunity to viral and other chronic infections.
Senior Researcher
Hyon Xhi focuses on immunology, mainly investigating adaptive immune responses against influenza. Using a combination of precise microscopy imaging and flow cytometry, he examines factors that enhance B cell responses in mucosal tissues such as the lung, which can act as a first line of defence against recurring influenza or SARS-CoV-2 infections.
Senior Researcher
Dr Lee was awarded his PhD in 2019, on studies investigating whether antibodies that mediate antibody-dependent cellular cytotoxicity (ADCC) could be utilised for an HIV cure. Dr Lee continues his work on ADCC antibodies against HIV and has recently pivoted to work on COVID-19, studying neutralising antibody responses and antibody Fc-mediated effector functions against SARS-CoV-2.
Senior Researcher
Marios completed his BSc in Biomedical Sciences at Imperial College in London, working with Professor Wendy Barclay on the molecular virology of influenza B viruses. Marios subsequently undertook a PhD at the University of Melbourne, focusing on understanding protective immunity to influenza viruses. Marios now works on the pre-clinical development of universal influenza vaccines and immunity to influenza B viruses.
Mai Vu
Researcher
Mai did her B. Pharm degree in Hanoi, Vietnam and did a MSc at Monash pharmacy. She recently completed a PhD at Monash Pharmacy in Parkville and joins the group to develop next-generation mRNA and nanoparticle vaccines to boost global pandemic preparedness efforts.
Lara Schwab
Researcher
Lara participated in the International Research Training Group, a PhD program between the University of Melbourne and the University of Bonn/Germany and was awarded her joint PhD degree in 2022. She was focusing on evaluating the antiviral activity of RIG-I agonists in different models of respiratory viral infections. Lara recently joined the group to expand upon her interests in viral respiratory diseases and will work on influenza B virus virology and immunology.
Chris Gonelli
Researcher
Chris completed his PhD in our department on various vaccine projects and has been working as a post doc at the NIH’s Vaccine Research Centre. He returns to Australia to work with Adam on a range on monoclonal antibody projects.

Researcher
Mitchell conducted his PhD with Linda Wakim and Pat Reading at the Doherty Institute and joined us to work with Jen Juno and her team on T cell immunity to pandemic pathogens.
Palak Mehta
Researcher
Palak completed a Masters in Wellington NZ and then a PhD with Kylie Quinn at RMIT on CAR T cells. She joins Jen to work on understanding T cell responses to vaccination in clinical cohorts
Thakshila Amarasena
Thakshila is an experienced technical scientist helping with our studies of viral quantification, sequencing and flow cytometry. She obtained her science degree in Sri Lanka and is a very experienced laboratory scientist. She is also our diligent safety and compliance officer.
Robyn Esterbauer
Robyn completed a BSc (Honors) in our department in 2016 topping her honors class. She has previously worked in several IT areas and brings a wide range of skills to our lab. She is working with Adam on several influenza immunity projects and is a very valued team member.
Kathleen Wragg
Kathleen first joined the lab in 2017, and then returned in 2024 following two years working at the University of Michigan. She is working with Jen on CD4 T cell immunity in clinical cohorts and pre-clinical animal models.
Andrew Kelly
Andrew joined the lab in 2021 and works with Robyn to oversee antibody and recombinant protein expression for the lab.
Ellie Reilly
Ellie completed her BSc Honours at the University of Wollongong in NSW. She previously worked with the Lung transplant service at the Alfred Hospital / Monash Immunology Department. Ellie joins us to work with Marios and Wen Shi on various immunology and virology projects
Lydia Murdiyarso
Lydia has a master's degree in Biomedical Science from Monash University. She has multiple years of technical experience in molecular biology and animal models. She is now working with Adam and Hyon-Xhi on B cell immunology and vaccine related projects.
Graduate Researchers
Lauren Drummond
Lauren joins us from Canada, where she did her undergraduate studies at McGill University. After working as a lab associate, she moved to Melbourne to start her PhD project. She will be working with Jen, Mai and Adam to study nanoparticle vaccines and germinal centre responses.
Devaki Pilapitiya
