David holds a Ph.D. in Molecular Biology and has spent nearly 20 years developing nucleic acid aptamers against a wide variety of targets including small molecules (antibiotics, food contaminants, chemotherapeutics), disease-associated proteins, several cancer-associated cell-lines, viruses and tissue biopsies. This work has been facilitated through the use of high-throughput, automated aptamer selection methods. David has built up an established international reputation in the field and has authored several peer-reviewed research articles, invited review articles and a book chapter on aptamer-based therapeutics. He has also given many guest seminars covering aptamer-based applications at top universities and international conferences.
