Postdoctoral Position at St. Jude Children’s Research Hospital

Postdoctoral Position at St. Jude Children’s Research Hospital

Title: Structural Biology: Tanja Mittag, PhD

Requisition Number: 6447

A postdoctoral position is available immediately for a highly motivated individual interested in studying the molecular basis of dynamic protein complexes in the ubiquitination pathway and cell cycle control in the laboratory of Tanja Mittag at St. Jude Children's Research Hospital in Memphis, TN USA. 70% of cancer-related proteins contain long disordered regions that convey important roles in cells, particularly in mediating interactions with other macromolecules in signal transduction. Disordered protein regions can execute their functions in the absence of a well-defined structure. It is becoming increasingly clear that even their complexes may remain largely disordered, allowing for unusual properties such as signal integration, graded and ultrasensitive responses. We will use NMR spectroscopy and other biophysical methods to elucidate molecular mechanisms of these protein interactions to understand their biological functions and the benefits of protein disorder.

The position is an ideal opportunity for either a candidate with experience in NMR spectroscopy to complement their training by learning other biochemical and biophysical techniques or for a biochemist/biophysicist interested in advanced protein NMR spectroscopy techniques. The fellow would benefit both from the excellent departmental facilities and from the collaborative St. Jude community. Candidates should have (or expect) a Ph.D. and/or M.D. and should have experience in protein expression, purification, and/or NMR spectroscopy.

Please apply online ( ) and send a CV with list of publications, a brief letter of research interests and goals and arrange for three reference letters to be forwarded to

Post-doc position opening in Orleans, France

We are currently looking for a post-doc candidate in the context of an international US-French collaborative project focusing on the local structures around active heteroatoms in boro- and alumino-silicate materials for catalysis. It is a three-year project that started in January 2010 and is co-funded by the French Agence Nationale pour la recherche (ANR) and the US National Science Fundation (NSF).

The work of the selected candidate will mainly focus on determining the molecular structures of alumino- and boro-silicate materials that cannot be accessed from XRD analyses. Therefore, he/she will combine semi-empirical and/or ab initio molecular dynamics and density functional theory (DFT) calculations with experimental solid-state nuclear magnetic resonance (NMR) data. He/she will have to develop semi-automatic protocols that integrate the large range of information that can be obtained using NMR spectroscopy, including chemical shifts, quadrupolar interactions, dipolar and scalar couplings and their calculation by DFT with quantum mechanical molecular modeling and structure-determination approaches to propose, solve, and refine the structure of layered and three-dimensional silicate materials and their B- or Al-incorporated analogs. He/she will explore the possibilities for modeling the local structural order and disorder around heteroatom sites and analyze their consistency with multidimensional correlated NMR data. Resulting interpretations of the local ordering and/or disordering at and near heteroatom sites will ultimately be correlated with the macroscopic properties of these materials to propose predictive models of their influence on catalytic properties of boro- and alumino-silicate materials.

The duration of the contract will be 18 months, with a salary of 1800-2500 euros/months depending on previous experience.

We are looking for a candidate with a PhD in the field of chemistry or physics with strong backgrounds in molecular modeling and materials chemistry. Practical experience with solid-state NMR spectroscopy will be considered a plus, but is not mandatory for the position.

The group ( of Dominique Massiot ( has a widely-recognized expertise in solid-state NMR of inorganic and hybrid organic-inorganic materials, and we are currently integrating increasing amounts of molecular modeling dedicated to the prediction of NMR parameters for the interpretation of experimental data. We have access and practical experience with codes such as CASTEP, Gaussian, and Quantum Espresso, with privileged access to local supercomputers.

samples that contain solid, gel and solution phase samples, the hardware is
globally unique and being co-developed directly with Bruker BioSpin. The Centre
focuses on the development and application of NMR techniques to study a range
of environmental problems. The current topics of research include:
environmental metabolomics, LC-SPE-NMR-MS applications to complex environmental
mixtures, in vivo NMR spectroscopy imaging, hyperpolarization, DNP, development
of multiphase NMR methods (solids, HR-MAS, solutions NMR as a single
technique). In addition, the Centre focuses on the development and application
of novel NMR approaches to complex systems (including soils, ocean sediments,
atmospheric deposits (particles, rain, snow, glacial ice), cells, tissues,
small organisms and other environmental matrices) to better understand
structure and environmental reactivity.
