Steffen became a licensed architect in Berlin in 1993 and has a deep understanding of architectural practice. In January 1993, he founded Steffen Lehmann Architekten & Staedtebau GmbH as a collective interdisciplinary practice engaged in research and design. Under Steffen’s leadership, the firm has been able to build a construction budget of $1b. Over ten years, he was actively involved in the urban creation of the 'New Berlin'.

Ph.D. Supervision: Since 2003, Steffen has been registered as Principal Ph.D. Supervisor, and he has successfully advised numerous Ph.D. students and postdoctoral Research Fellows as Primary  Ph.D Supervisor (12 Ph.D. students and 3 post- doctoral fellows), in the US, the UK and in Australia. He has been appointed as External Ph.D. Examiner by top universities, including the University of Sydney, Univ. of Western Australia, Bond University, Univ. of Salford, KTH Stockholm, Hong Kong Poly University, University of Portsmouth, and the University of Greenwich. As Head of School in Australia, he oversaw a cohort of 85 Ph.D. students. He is mentoring early career researchers, providing them with opportunities within his research groups and ongoing projects.

Public speaking: He is an engaging speaker, and over the last 30 years, Prof Lehmann has presented his research and design work publicly over 600 times at conferences, symposia and important events, in 40 countries, including delivering over 100 invited keynote addresses.

In 2003, he founded the “Global Studio” series, and since then coordinated Global Studios at: TU-Berlin, TU-Munich, Tongji Shanghai, NUS Singapore, Iberoamericana Mexico City, ANU Ahmedabad India, and Papua New Guinea University of Technology.

For many years, Steffen has been a passionate advocate and champion for diversity, equal pay, and the advancement of female graduates and under- represented ethnic populations. He believes that diversity and mentoring programs contribute to a rich and stimulating learning and research environment, one that best prepares the leaders-in-the-making for the challenges and opportunities of tomorrow; and the importance to offer students richly varied perspectives, approaches and ways of knowing and learning. The question of how the profession can become more equitable, diverse and inclusive means to address the challenges of our time. While recruiting and building a diverse faculty varies by discipline, there are particular opportunities in the design disciplines and social sciences that could give these disciplines a leadership role in making diversity happen. Steffen’s influence extends well beyond Nevada and the USA, and here are examples of the numerous activities where he has pro-actively supported the goal of diversity:

  • Reconnects with alumni and introduced new student awards and scholarships for female students and for first-generation students from under-represented minorities.
  • Closely collaborates with the Disability Resource Center, that students with all kinds of learning disabilities receive particular accommodations.
  • Organized high-quality public symposia and annual lecture series featuring female and minority colleagues; e.g. initiated the SAY IT LOUD – NEVADA exhibition and symposium (2020), and initiated the Latin-American Architecture symposium at UNLV (as part of AIA’19 National Conference).
  • In collaboration with the AIA and others, he has championed fund-raising activities to offer scholarships and awards to female and minority students.
