Alastair McEwan is Dean of the Graduate School at the University of Queensland. He holds a BSc(Hons) in Biochemistry from the University of Leeds and a PhD in Biochemistry from the University of Birmingham. Following periods as a research fellow at the University of Illinois at Urbana-Champaign (SERC NATO Postdoctoral Fellowship) and the University of Oxford (Royal Society 1983 University Research Fellowship) he was appointed to a lectureship at the University of East Anglia, Norwich. He joined the University of Queensland in 1993 and was appoined Professor of Microbiology in 2003. Professor McEwan's research interests include bacterial physiology and bioenergetics, redox biology, biochemistry of metalloproteins, chemical biology of transition metals, bacterial pathogenesis and host-pathogen interactions.
