Dian specialises in the preparation and prosecution of patent applications in the fields of chemistry and pharmaceuticals.  She also provides advice on patentability, validity, infringement and filing strategy.

Dian holds an honours degree in chemistry and a PhD in organic chemistry from the University of Edinburgh.  Her PhD research into the use of reactive intermediates in heterocyclic chemistry was funded by a postgraduate scholarship from BP plc.

Dian joined Davies Collison Cave in 2015 after spending four years with another Australian patent firm where she qualified as an Australian patent attorney.  Prior to moving to Australia, she spent 11 years with the intellectual property department of Smithkline Beecham (later GlaxoSmithKline) in the UK where she qualified as a European and UK patent attorney.  During this time she gained experience in a variety of contentious and non-contentious patent matters.  She successfully secured patent protection for pharmaceutical products and clinical candidates in most major markets in addition to identifying and pursuing patent term extension opportunities for key products.  She also obtained experience in contentious matters in Eastern Europe, India, Russia and China.

Before embarking on a career in patents, Dian obtained trans-national industrial research experience during 10 years with 3M Corp where she carried out research into novel small molecules for several technology areas including imaging systems and flame retardant composites.  During this time, she was a named inventor on several patents and received a number of awards for technical achievement.
