The Research Stays at TU Berlin program provides international bachelor's and master's students with the opportunity to conduct research, complete final theses, or participate in Erasmus+ traineeships across the university's diverse faculties. These stays are highly individualized and allow students to integrate into existing research groups or work on independent projects under the academic supervision of TU Berlin professors. Interested students can find specific research topics through the (International) Student Thesis and Research Opportunities Database (ISTROD) and the Stellenticket portal, or they may pursue unsolicited applications by contacting academic chairs directly. Successful candidates who receive a letter of invitation from a host professor are eligible for temporary enrollment at the university, which grants them access to campus infrastructure, library services, and IT facilities. While the Department of International Affairs provides general information, the primary academic and administrative support—including assistance with enrollment procedures and local orientation—is handled directly by the hosting faculty. Participants are responsible for their own funding, health insurance, and visa arrangements, although they may utilize international mobility grants such as Erasmus+ funding where applicable. This program serves as a flexible platform for international scholars to gain hands-on research experience and foster academic collaboration in a professional German university setting.
