About me

I'm a PhD student with Frans Snik (Leiden Observatory) and Martina Vijver (CML).
I am part of the Instrumentation group at Leiden Observatory and of the Environmental Biology group at CML.
My main project is the development of iSPEX 2, a smartphone spectropolarimeter add-on for citizen science. For more information, please see the MONOCLE website.
Feel free to contact me via email [burggraaff (at)] or in my office (HL 1101).
