At Brandeis, Klausen has taught undergraduate and graduate courses or classes that have focused on immigration, law and human rights, and religion and secularism through the lens of conflicts over the integration of Islam and Muslims in the West.
[4] Klausen's second single-authored book, "The Islamic Challenge: Politics and Religion in Western Europe" (2005, 2007pb), was based on intensive interviews with Muslim politicians that she conducted in a number of European countries.
[5] This book was a study of the global protests against the Danish newspaper Jyllands-Posten following the publication of twelve satirical drawings portraying Muhammad.
Klausen's WEP uses a purpose-built relational database in PostgreSQL to establish a reliable model for radicalization trajectories across extremist ideologies based on an archival collection of publicly sourced data and audio-visual files including: photographs, videos, propaganda, magazines, sermons, court documents, and news reports.
In 2007, Klausen also received the Carnegie Scholars’ Award in support of her research on the integration of Muslim faith communities in Europe.
