Winney is currently working towards registration as a patent attorney.
Before pivoting her career to IP, Winney was a visiting fellow at the University of Melbourne and a research fellow at the Australian National University, where she specialised in developing novel solar cell schemes. She was also a co-lecturer for several Physics and Engineering courses at the ANU, both at undergraduate and Masters levels.
As a PhD student, Winney conducted research on non-equilibrium semiconductor materials for optoelectronic applications, where she used techniques such as ion implantation and pulsed laser melting to produce highly non-equilibrium semiconductor materials, and a wide suite of characterisation techniques to understand their behaviour. During this time, she has worked with a large team of international researchers on several related interdisciplinary projects and has published numerous journal articles, an invited review paper, and an invited book chapter. Her thesis was awarded the Jagadishawar Mahanty Prize for being the most outstanding PhD thesis submitted in the Research School of Physics, ANU. She has also won a Gold medal in Graduate Student Prizes, the premier student prize awarded by Materials Research Society.
