He has linked this activity to the evaluation and refinement of techniques within prospective randomised clinical trials. He has authored more than 350 refereed research papers and book chapters. Since 1997 he has also received 16 major research grants from NHMRC and NIH, as well as major grant support from other funding bodies.

Offsetting transactions are common in options and futures markets . For example, let's say John Doe sells an option to buy 100 shares of Company XYZ with a strike price of $20 per share. The option expires in one year . Because John is locked into the contract, he cannot just ignore it. So, he enters into an offsetting transaction by buying an identical opposite transaction (buying an option to sell 100 shares of Company XYZ with a strike price of $20 that expires in one year). This offsets the risk he bears with the first option.
