Professor Bezalel Narkiss headed the CJA until 1991 . The next director , Professor Aliza Cohen-Mushlin , established a fifth section for Jewish Ritual Architecture and Funerary Art . Under her leadership the CJA undertook many research expeditions to post-Communist Central and Eastern Europe , in order to measure endangered synagogues and tombstones in regions , which were previously inaccessible to western scholars . In addition , from 1994 CJA documented those synagogues in Germany which survived the Nazi regime and were not demolished in Kristallnacht . The documentation projects in Germany were done in cooperation with the Department of Architectural History at the Technical University in Braunschweig , headed by Professor Harmen H. Thies . In 1997 this cooperation was institutionalized as Bet Tfila Research Unit for Jewish Architecture in Europe
