Biography

Helle K Falkenberg graduated as an optometrist at Kongsberg Ingeniørhøgskole in 1996, and went on to study Optometry and Vision Science at Glasgow Caledonian University, UK. She graduated in 1998, and qualified as an optometrist in 1999 after completing her pre-registration year at the Glasgow Caledonian Eye Clinic. She received her PhD in Optometry and Vision Science from Glasgow Caledonian University with Dr William Simpson. She moved to the Institute of Ophthalmology, University College London where she did her postdoctoral research with Dr Pete Bex. Helle has continued to practice optometry throughout her career and supervised optometry students at Glasgow Caledonian and London City University. She is a member of The College of Optometrists, NOF, OSA, VSS and ARVO.

Dr Falkenberg’s research uses psychophysical methods to study visual motion perception in normal development, aging and in patients with impaired vision. She applies behavioural techniques to understand the deficits in patients with central or peripheral visual field loss. She is particularly interested in how ideal observer/ equivalent noise models can be used to investigate suboptimal human performance in motion detection and discrimination tasks in normal and impaired vision. Her research also involves studies on mobility, and how patients with visual field loss use their remaining field of vision to get around, and the use of natural scenes to investigate human behaviour.

Research Interests

- Visual motion perception (development, normal, deficient)
