Dr Hanna Evelina Sidjabat is currently a Chief Investigator within the Infection and Immunity Theme at the UQ Centre for Clinical Research. Dr. Sidjabat continues her probiotic research for gastrointestinal tract and upper airway. Probiotic development capable in decolonising antibiotic-resistant bacteria from gastrointestinal tract will be the emphasise of Dr. Sidjabat's current probiotic research. Dr. Sidjabat was the lead microbiologist of Professor Anders Cervin in research into upper respiratory tract microbiome and Australian Indigenous children with otitis media (Jan 2015 - Jul 2017). Dr Sidjabat continues her work in probiotic development for clinical trial in chronic rhinosinusitis patients of Prof. Anders Cervin as a collaborator. Dr Sidjabat is a recognised expert in Australia in the area of molecular microbiology with over 13 years of experience working with antibiotic resistant Gram-negative bacteria. She was in charge of Prof. David L. Paterson's laboratory for 6.5 years at the University of Queensland Centre for Clinical Research. Prior to that, she was working at the Division of Infectious Diseases, University of Pittsburgh, Pennsylvania, USA under the supervision of A/Prof. Yohei Doi for 1.5 years. She has worked collaboratively with many leading microbiology laboratories nationally and internationally.

Dr. Sidjabat completed her Bachelor of Veterinary Science and Doctor of Veterinary Medicine (BVSc and DVM) from the Gadjah Mada University, Indonesia and proceeded to complete her post graduate diploma in food-borne pathogens, Masters in Verocytotoxin-producing Escherichia coli and PhD in antibiotic resistance bacteria of companion animals at the School of Veterinary Science, University of Queensland, Australia. She is currently completing her Graduate Certificate for Higher Education at the University of Queensland.

In parallel with her research career, she has been passionate about teaching. She lectured full-time in Microbiology and Immunology for medical and nursing students between 2001 and 2003 in Indonesia. In 2014 she was a guest lecturer in Microbiology at the Sunshine Coast University and at various universities in South East Asia.

To date, she has published 76 peer-reviewed articles. Dr. Sidjabat has been the proud recipient of travel awards from the Australian Society for Antimicrobials 2011, 2013 and 2014. She also received Shimadzu UQCCR Research Excellence Travel Award in 2012.

Following the completion of her PhD in 2007 she has supervised and mentored 34 PhD students, Postdoctoral Research Fellows, Masters students, Honors students, Microbiology registrars, local and international Infectious Diseases visiting academics and other young physicians and junior scientists who are keen to explore research.

Research Interests
