Summary

SPECK LAB OVERVIEW

The group's objective is to discover new mechanisms in initiation of DNA replication and to understand the function of replication factors in hetero-chromatin formation and epigenetic memory. This knowledge is used to understand disease-associated processes and to develop novel DNA replication inhibitors. We employ truly interdisciplinary approaches including biochemistry, cryo-EM, high-resolution genomics, chemical biology, genetics and molecular dynamics simulations to obtain a holistic understanding of biological processes.

We collaborate with ICL Chemistry (Anna Barnard, ICL White City Campus) and MRC-LMS (Alexis Barr, Hammersmith Campus) to exploit our biological insights for inhibitor development. Together with DeepChain we use molecular dynamics simulations and AI-driven analysis of protein sequences to understand the function of multi-protein complexes.  

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

POSTDOC POSITION AVAILABLE FOR 2023/2024

Interested in how cells control their DNA replication? So are we! Join us for a 3-year postdoc position (£45,593 – £49,305 per annum) to discover how efficient human DNA replication works at a molecular level using biochemical/structural tools.

Currently, it is not known how human DNA replication origins are chosen or how they can be controlled, but this understanding has enormous relevance for genome stability and cancer biology. Thus, we aim to research 1.) how DNA replication origins are specified through epigenetic mechanisms and specific recruitment factors and 2.) how DNA replication is regulated to allow faithful DNA replication. We will further ask how mutations in these processes contribute to genome instability and whether they are enriched in cancer.

Position: Biochemistry/Structural Biology:

We have recently reconstituted human DNA helicase loading using purified proteins. The successful candidate will use the system to investigate the targeting, assembly, function and regulation of human helicase loading using biochemical/biophysical tools. Genomewide AlphaFold screens will allow us to identify novel factors involved in this process. Consequently, these interactions will be characterised by biochemical and structural approaches in order to understand their function in helicase loading. This work will contribute to a fundamental understanding of DNA replication and how this process is regulated and implemented. Given the pivotal role of successful helicase loading on tumorigenesis, it will also direct us toward novel therapeutic targets. 

Who we look for:

We seek a creative researcher who enjoys tackling ambitious research questions. You should be experienced in protein expression, purification of multi-subunit complexes and biochemical assays. Enjoying methods development would be a big plus. The candidate should relish discussing science, be social and good at networking. This project is ideal for candidates who want to switch fields and learn cryo-EM. Prior experience in the supervision of master students would be welcome. Professor Speck will mentor you in grant writing, networking and publishing. Indeed, the scientific framework and the support by Prof. Speck means that the candidates are well placed for a successful transition into independence.

How to apply:

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 Biochemical Journal, chairs the Institutes Athena Swan committee and sits on the Clinical Science Centre Postgraduate Education Committee. 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 London to establish his group in 2006 at MRC-CSC and since 2013 at Imperial College London, 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. 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 S, 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.
