Overview

I was born in Canada to a Jewish mother and an ex-catholic priest. After 28 days I left for Israel and stayed there for 24 years until I then moved again to Sweden. The international and multicultural upbringing I’ve received, combined with studying in universities in Israel, Canada and Sweden, allowed me to appreciate differences between cultures and backgrounds as being advantages rather than hinders.

Research Interests

  • Visual ecology
    I'm interested in the visual ecology of fish, spiders, cephalopods, mantis shrimps, and zooplankton. More specifically, I've worked on colour vision, navigation, camouflage, polarisation, and light scattering with these animals. I love combining interdisciplinary fields of science because it most often produces very fascinating and otherwise unattainable results.

Research Impacts

I've submitted a business plan for the application of multifocal lenses in the optics industry for mobile phones and cameras at the Venture Cup Southern Sweden (http://venturecup.se/) and won 2nd place. This application was inspired by special lenses found in fish eyes that can compensate for chromatic blur -- a phenomena that limits the image quality of many small cameras (such as the ones found in mobile phones and laptops).
