Dr Harendra (Harry) S Parekh

Senior Lecturer & Research Group Leader – Pharmacy Australia Centre of Excellence, The University of Queensland, Brisbane, Australia.



Dr Parekh obtained a Bachelor of Science in Pharmacy with 1st Class Honours from the University of Portsmouth, UK in 1997. Upon successful completion of his pre-registration internship with Boots The Chemists (London) he registered as a Pharmacist with the Royal Pharmaceutical Society of GB in 1998, and his membership remains current today.

In late 1998 Harry Parekh was awarded a BBSRC scholarship, enrolling in the PhD program at The University of Nottingham (UK) within the School of Pharmaceutical Sciences under the supervision of Dr B. Kellam and Dr S.R. Chhabra. He was awarded his PhD in Medicinal Chemistry in 2002, relocating to Australia in 2003.

From 2003-2005 Dr Parekh was a research fellow on a National Health and Medical Research Council (NHMRC) grant, developing novel non-viral vectors for gene delivery. In 2004 his technology for treating age-related macular degeneration was awarded the Trailblazer ‘Open Winner’ prize for commercial potential, by Uniquest Pty LTD.

In 2005 Dr Parekh attained Pharmacy Board registration in QLD (Australia). In the same year he was appointed Lecturer within the School of Pharmacy and set about establishing his own laboratory focusing his research on engineering advanced non-viral drug and gene delivery systems. In 2007, for the 2nd time, Dr Parekh was awarded the Trailblazer ‘Open Winner’ prize for his antibody targeted gene delivery system.

In 2009 Dr Parekh was appointed adjunct-Senior Lecturer at Manipal University, India, having also delivered invited seminars to key research and teaching institutions in Germany and Singapore with active collaborations spanning the globe also including the USA, Brazil and UK. To-date (2013) Dr Parekh has graduated 5 Honours, 2 Masters and 4 PhD students from his group, with his research being funded by the NHMRC, Deutscher Akademischer Austausch Dienst-Group of 8 Council, Cancer Council of Queensland, The University of Queensland, Australian Medical Association-QLD node and Uniquest Pty LTD.

Research Areas:

• Dendrimer-mediated drug & gene delivery
• Bubble liposomes in drug and gene delivery
• Transdermal drug/gene delivery
• Traditional Chinese Medicine into the 21st century
• Molecular dynamics simulation of gene-carrier systems

Research Interest:

The ‘nanotech’ age is firmly upon us and with this comes the exciting prospect that researchers will, in time, deliver on their promise to work towards innovative and practical therapeutic solutions against a wide range of acute and chronic diseases, which afflict both young and old alike. Research being conducted in the Parekh laboratory at the University of Queensland and Bio-Lab at NUSNNI (in collaboration with Assoc. Prof. Giorgia Pastorin) is dedicated to this cause, where a range of chemically-derived carrier systems are being systematically developed, holding much promise as vehicles for the safe and targeted delivery, as well as release of various drugs/genes in vivo.
