OBJECTIVES OF THE DK MOLECULAR ENZYMOLOGY

  • Provide a group of well-prepared and talented students with a challenging doctoral program based on a framework of matching interdisciplinary scientific topics. These topics will be sufficiently focused so that exchange of ideas among students can occur, but also sufficiently diverse that students can have a look beyond the immediate problems related to their thesis research;

  • Offer an integrated program of training opportunities for the best of our students to prepare them for a career in molecular biosciences on an internationally competitive level;

  • Act as academic complement for the existing inter-institutional collaborative research networks (SFB LIPOTOX, GEN-AU project GOLD, Kplus Center Applied Biocatalysis). This synergistic connection strengthens the integration of the PhD program while facilitating the research goals of the projects;

  • Facilitate, enhance and enforce the international exposure of participating students;

  • Make expertise and infrastructure of the participating laboratories available to all graduate students to provide a strong interdisciplinary research environment for PhD training;

  • Generate a structure to organize and coordinate doctoral training activities for the Graz university cluster (KFUG, TUG and the MUG);

  • Set and maintain benchmark standards for doctoral education in the molecular biosciences


    RESEARCH OVERVIEW

    Original research performed by the doctoral students fit well under the thematic umbrella “Molecular Enzymology“.

    The broad areas of interest are:

  • cellular lipid metabolism
  • biocatalysis
  • enzyme mechanisms and cellular functions in broader aspects of biology


    Dissertation projects for the new funding period (2008 to 2011) are again embedded firmly in an exceptional network of research programs [SFB LIPOTOX, GEN-AU project GOLD II, Kplus Center Applied Biocatalysis, and the national research network AGING]. Topics for ongoing thesis work are listed under projects (link). To provide a basic overview of Molecular Enzymology's scientific objectives, they can be structured into five interrelated components:

  • Discovery of Enzymes
  • Enzyme Structure
  • Enzyme Mechanisms
  • Cellular and Metabolic Functions of Enzymes
  • Exploitation of Enzymes for Biotechnological and Pharmaceutical Applications


    RESEARCH STAYS ABROAD

    A key aspect of FWF financed DK programs is the emphasis placed on performing part of the thesis project at one or more different research institutions for a period of at least 6 months. Typically students work with their thesis committee to select an appropriate host laboratory among international research institutions for the collaboration. Depending on the research aims, students can divide their time abroad between two different laboratories. If the student spends a minimum of 6 months outside of the home laboratory, the student becomes eligible for a fourth year of salary in order to complete the degree requirements for doctoral studies at the home university. All students must complete their degrees by the end of the fourth year.

    DK students have carried out research stays at the following institutions:

  • Institute of Environmental Medicine, Karolinska Institute Stockholm, Sweden
  • Dept. of Biological Chemistry, University of Michigan Medical School, Ann Arbor, Michigan, US

    INTEGRATION OF THE DK IN DOCTORAL SCHOOLS


    The Doctoral School Molecular Biosciences and Biotechnology maintains an interuniversity program for doctoral students of the molecular biosciences as a joint venture of the TU Graz and the KFU Graz. The program was launched as a NAWI-Graz project during the academic year 2007/08. Typically more than 120 doctoral students of the molecular biosciences and biotechnology at both universities, as well as the Institute of Biophysics and Nanosystems Research of the Austrian Academy of Sciences are enrolled.


    The NAWI Graz Doctoral School thus jointly coordinates the Doctoral School of Molecular Biology and Biochemistry of the KFUG (link) and the Doctoral School Molecular Biosciences and Biotechnology of the TUG (link).
