Dr. Marcus Altmaier

Dr. Marcus Altmaier studied chemistry at the University of Cologne, where he submitted his doctorate in 1999 in the field of nuclear chemistry . M. Altmaier has been working at the Institute for Nuclear Waste Management at the Karlsruhe Institute of Technology (KIT-INE) since December 2000. KIT-INE works in the context of safety research on nuclear waste disposal. The main activities focus on researching various (geo) chemical processes that may be required in the context of safety analyzes. Nuclear chemistry work is very relevant in this field of work in order to be able to reliably predict the behavior of long-lived radionuclides such as plutonium in different scenarios.

The scientific work of M. Altmaier primarily covers the chemistry of actinides and long-lasting fission products in aqueous solution. Numerous studies deal with the solubility and complex formation of actinides in repository-relevant aquatic systems. The basic scientific work includes the determination and evaluation of thermodynamic data as well as the derivation of reliable model parameters for the description of ion-ion interaction processes. The work requires complementary spectroscopic analyzes and Mr. Altmaier has gained a good overview of modern analytical and radiochemical methods based on many years of experience in this research area. Dr. Altmaier works in numerous application-related third-party funded projects as part of basic security research. One focus here is the preparation and coordination of joint projects in a European and international context.

dr Catherine Mueller

dr Katharina Müller has headed the "Interface Processes" department at the Institute for Resource Ecology at the Helmholtz-Zentrum Dresden-Rossendorf (IRE / HZDR) since 2021.

After studying waste management and contaminated sites at the TU Dresden and a research stay at the Universidade Federal de Minas Gerais (Brazil), she received her doctorate in 2010 at the former Institute for Radiochemistry of the Research Center Dresden-Rossendorf. She then received research grants at the École Nationale Supérieur de Chimie de Paris (France) and at Kyoto University (Japan).

In the "Interface Processes" department at the IRE / HZDR, she and her colleagues investigate the reactions of long-lived radionuclides at water-mineral interfaces. To do this, they combine modern methods of spectroscopy and microscopy for in-situ investigation of the molecular environment of actinides and fission products in aqueous solutions, at interfaces and in solid phases. Determined complex formation reactions and complex structures can characterize and quantify these interactions. They thus form a solid basis for a reliable thermodynamic description of the systems under investigation, which can be integrated into thermodynamic databases. The quality-assured databases are in turn the basis for forecast calculations on the mobility of radionuclides as part of a long-term safety analysis of nuclear waste repositories.

Prof. Dr. Petra J. Panak

Prof. Dr. Petra J. Panak is a professor of radiochemistry at the Ruprecht-Karls-University of Heidelberg (EnBW endowed professorship). After studying chemistry at the Technical University of Munich, she completed her doctorate (department of actinide chemistry) at the Institute for Radiochemistry at the Technical University of Munich under the direction of Prof. Dr. JI Kim on. This was followed by stays at the Institute for Radiochemistry at the Dresden-Rossendorf Research Center and at the Lawrence Berkeley National Laboratory, California. The focus of research at that time was microbial interactions of the actinides. The habilitation took place in 2008 at the Ruprecht-Karls University of Heidelberg on "aquatic chemistry of actinides in colloidal systems". In November 2008 she followed the call to the EnBW endowed professorship "Radiochemistry" at the University of Heidelberg. At the same time, she is head of the group "Coordination Chemistry of Actinides" at the KIT Institute for Nuclear Waste Management, Campus North. Since February 2014 she has been a member of the Committee on Disposal of Radioactive Waste (EL) of the Waste Management Commission (ESK). In September 2014 she was appointed to the supervisory board of the Helmholtz-Zentrum Dresden-Rossendorf.

Dr. Alice Seibert

Dr. Alice Seibert studied chemistry at Johannes Gutenberg University Mainz and received her doctorate in 1999 at the Institute for Nuclear Chemistry there with Prof. Dr. Jens-Volker Kratz as part of a joint federal project on repository research. After completing her doctorate, she continued this topic at the University of Mainz.

From 2001 to 2005 she worked at the Institute for Nuclear Waste Management at the Karlsruhe Research Center (today Karlsruhe Institute of Technology (KIT-INE) in the field of the aquatic chemistry of actinides. After a scholarship at the Institute for Transuranium Elements (today Joint Research Center Karlsruhe, JRC Karlsruhe) in the field of surface science and fuel corrosion, in 2011 she moved to WAK GmbH reprocessing plant Karlsruhe, (now KTE) to take on scientific advice on ongoing operational and contract work in dismantling and the accreditation of the radiochemical laboratory.

Since the end of 2013 she has been employed as an official of the European Commission at the JRC Karlsruhe and is involved in projects in the field of nuclear safety research and disposal.
