Prof. Lilya Budaghyan is a head of Selmer Center in Secure Communication at the University of Bergen and a leader of Boolean functions research team there.

Her main research interests are in the field of Boolean functions and their applications.

She obtained her PhD degree from the University of Magdeburg (Germany, 2005) and habilitation degree from the University of Paris VIII (France, 2013).

She is author of the book "Construction and Analysis of Cryptographic Functions", and has been awarded a few prestigious fellowships and awards among which are Bergen Research Foundation award (2016), “Young Research Talent Grant” from Norwegian Research Council (2014), postdoctoral fellowship award from Foundation of Mathematical Sciences of Paris (2012) and Emil Artin Junior Prize in Mathematics (2011).

Since 2007 she has been with the University of Bergen (Norway). Previously, she also conducted her research at the Yerevan State University (Armenia, 1998-2003), University of Magdeburg (Germany, 2003-2005), University of Trento (Italy, 2005-2007), Telecom ParisTech (2011), Universities of Paris VIII and Paris XIII (2012-2013).
