Summary

SPECK LAB OVERVIEW

The objective of the group is to discover new mechanisms in the initiation and elongation of DNA replication and to understand the function of replication factors in hetero-chromatin formation. We have reconstituted the loading of the eukaryotic replicative helicase onto DNA, an essential step in DNA replication and  use this system to address the mechanism and regulation of two key events: the loading of the eukaryotic DNA helicase onto DNA and the kinase dependent activation of the helicase. More recently, we have started to investigate the role of the helicase loading factors in epigenetic memory, which has important implications for human disease and aging.

Enquires from motivated and exceptional students and postdocs to work in the group are always welcome. Please send full CV and cover letter to: chris.speck@imperial.ac.uk

About Prof. Christian Speck

   Christian is a Professor of Genome Biochemistry & Molecular Biology at the Institute for Clinical Sciences in the Faculty of Medicine. He is a Fellow of the Royal Society of Biology (FRSB) and has been the recipient of two prestigious research fellowships from an US charity foundation and the Max Planck Society, research grants from the UK research councils, and   received the Wellcome Trust Investigator award in 2015. Christian served as an invited panel member during the scientific evaluation of the Horizon 2020-MSCA-IF-2016/2017- LIF, DAAD  and the French National Research Agency - ANR. He sits on the editorial board of the Journals Microbial Cell, Biochemical Journal, chairs the Institutes Athena Swan committee and sits on the Clinical Science Centre Postgraduate Education Committee. He has given oral presentations at the renowned Cold Spring Harbor DNA replication meeting for the last 10 years. Christian has been invited to numerous European and UK universities for research seminars and as a session Chair to the Cold Spring Harbor Replication meeting and the FEBS Congress . During his B.Sc. degree in biotechnology at the Beuth Hochschule of Berlin, Prof. Speck undertook a project at Genentech Inc in South San Francisco USA for 6 month in the laboratory of Dave Goeddel (CSO, Genentech) to get industry experience. Christian obtained his Ph.D. in biochemistry from the Free University of Berlin under the guidance of the late Prof. Walter Messer working at the Max-Planck institute of Molecular Genetics, while being funded by a Max-Planck Fellowship to study bacterial DNA replication. This work resulted in 3 first author publications including two in EMBO Journal. He then moved to the US to work with Bruce Stillman, President of the Cold Spring Harbor Laboratory, while being supported by a Leukaemia and Lymphoma Research Fellowship exploring eukaryotic DNA replication and the role of Cdc6 in initiation of DNA replication. This work resulted in 4 first author publications in Nature Structural & Molecular Biology, PNAS and JBC. Following this period of training he moved to Imperial College London to establish his group in 2006 at MRC-CSC and since 2013 at Imperial College, Institute of Clinical Science. His group reconstituted the loading of the replicative helicase with purified proteins (F1000 – excellent) and identified a series of crucial mechanisms and regulatory principles in DNA replication being published in prominent journals such as Molecular Cell, Nature Structural & Molecular Biology Genes & Development and PNAS. In 2017 he became one of the founding members of the Wellcome Trust funded LonCEM consortium, which was awarded a Titan Krios cryo-EM with K3 detector currently being set-up.  In the same year, he became a member of the Imperial College London Centre for Structural Biology (CSB) and in 2018 member of the associated Block Allocation Group (BAG) for flexible access to the Krios 1-4 of eBIC (Diamond Light Source - Harwell). In 2017 Christian, while being supported by Sarah, has set-up the local cryo-EM screening facility at the Institute of Clinical Sciences. The facility is by now is fully operational and supports the electron microscopy efforts of the whole institute.
