We, the MRS University Chapter Cologne and friends, want to express our gratitude for your dedicated and seminal work as former president MRS University Chapter Cologne! We all miss your harmony and joyful charisma in our group.

Dr. Isabel Gessner was always our driver for student engagement activities at the institute through the organization of MRS lecture series with high-quality talks and on-site at MRS Fall/Spring Meetings since 2015. We thank you for suitable mentoring commitments that connecting new MRS Chapter members to international experts on cutting-edge nanotechnologies for sustainable innovations and career development programs. Your leading work was a highlight by the first student-led symposium on “Nanotechnology and Sustainability” at the MRS Fall Meeting in Boston 2017. Isabel’s never-ending motivation on activities on spreading the word of sustainability in daily life, in her research at the University of Cologne and within the framework of MRS task force “Focus on Sustainability” revealed her passion for global collaboration on sustainable developments. Thank you, Isabel, for sharing your vision on the responsibility of sustainability beyond our research activity. We wish you all the best in your new postdoc position at the Harvard medical school and Massachusetts General Hospital, Boston, USA and are very happy that you are preserved as our advisor.
