About the Chair
Dr. Jens Breffke is a member of the International Activities Committee (IAC) of the American Chemical Society and is its new Chair. Jens is the photon counting application specialist at Boston Electronics in Brookline, Massachusetts. As the North American engineer for Becker & Hickl products he supports scientists with time-correlated single-photon counting technology for applications like Fluorescence Lifetime Imaging (FLIM), Fluorescence Resonant Energy Transfer (FRET) and Light Detection and Ranging (LIDAR).
Jens received his Ph.D. at The Pennsylvania State University (Penn State) with his dissertation on the study of ultrafast molecular rotor and proton transfer dynamics in solution in the group of Prof. Mark Maroncelli. He holds a Diplom degree from the Humboldt-University in Berlin, Germany. Prior his current employment he was working as a postdoctoral research fellow at the U.S. National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland under Dr. Stephan Stranick on the development of time-resolving structural illumination microscopy. He has published several peer-reviewed articles and has presented his work both nationally and internationally.
His international engagements started in 2007 when he hosted, as chair of the German JungChemikerForum (JCF), the founding meeting of the European Young Chemists Network (EYCN) of the European Association of Chemical Molecular Sciences (EuCheMS). He belonged to its board for several years thereafter. After his transition from Germany to the U.S. he joined the ACS Younger Chemists Committee in 2010. Initially leading a task force on international presence which later became a subcommittee working group, he established the international exchange program “Younger Chemists Crossing Borders” (YCCB). This program brings younger scientists across the globe to international conferences for professional development and was completed by additional social and professional programming following the meeting. Jens served on ACS president Marinda Wu’s “Vision 2015” task force.
In 2015 he hosted with Dr. Luke Roberson of IAC the first workshop on the concept of an International Younger Chemists Network (IYCN) at the 250th ACS National Meeting & Exposition in Boston, MA. Jens has since become an advocate for IYCN and promoted it with the International Union of Pure and Applied Chemistry (IUPAC). As a 2017 IUPAC Young Observer he attended the IUPAC World Chemistry Congress in Sao Paulo, Brazil, at which IYCN was officially founded as the younger scientist entity of IUPAC.
Jens’s mission for IAC is the coalignment of ACS’s global effort with its committees, technical divisions, and international chemical sciences chapters with national sister societies.
