[edit] Imaging
Raph Levien's main research interest is in the theory of imaging, that is, rendering pictures and fonts so that they can be displayed electronically. He has written several papers on his research in halftoning technology, which have been implemented in the Gimp-Print free software package, as well as by several commercial implementations.
[edit] Influence in Free Software community
In March 2000, Raph made a patent grant of his patent portfolio to the GPL community. This step was considered by some to have set a good example, and it has been suggested that it set a precedent for IBM's subsequent patent grant, which followed two years later.
[edit] Activism against encryption export regulations
Raph played a small part in precipitating the relaxation of the US crypto export legislation, by filing for a Commodities Jurisdiction Request for a t-shirt containing an implementation of the RSA encryption algorithm, in four lines of Perl. At the time (1995), the code on the t-shirt would have been regarded as a munition by the United States and other NATO governments.
[edit] Personal life
He is divorced, with two sons: Alan and Max. He is a member of the Berkeley Monthly Meeting [1] of the Religious Society of Friends (Quakers).
