Postdoctoral Fellow

School of Biotech & Biomolecular Science

Dr. Alquethamy is an Early Career Postdoctoral Fellow at the University of New South Wales (UNSW), specialising in bacteriology and RNA biology. He obtained his PhD in Microbiology from the Peter Doherty Institute at the University of Melbourne in 2023, followed by a postdoctoral appointment at Flinders University. His current research leverages the regulatory functions of bacterial small RNAs (sRNAs) to enhance antisense oligonucleotides, aiming to develop novel RNA antibiotics targeting antibiotic-resistant bacteria. His previous research combined membrane protein biochemistry, molecular microbiology, animal models of infection, structural biology, and biophysical techniques to elucidate how bacterial pathogens selectively transport essential nutrients, such as metal ions and lipids, across biological membranes.

Dr. Alquethamy has published nine peer-reviewed articles, including five as first author. His publications have accumulated over 140 citations in the past five years, all in top quartile (Q1) journals within their fields. Notably, he has published in high-impact journals such as Nucleic Acids Research (IF=16.6), mBio (IF=5.1), and the International Journal of Molecular Sciences (IF=4.9). Dr. Alquethamy has received multiple scholarships and awards, including two recent Early Career Researcher (ECR) grants from UNSW's School of Biotechnology and Biomolecular Sciences. He is also an active committee member of the Australian Society for Microbiology (ASM).
