Professor Thomas Mock
Group Leader | Principal Investigator | Fellow of Higher Education Academy
I obtained my MSc (1998) in Biology with emphasis on Biological Oceanography at the Christian-Albrechts University in Kiel and the PhD (2003) at Bremen University (Alfred-Wegener Institute for Polar and Marine Research), Germany. Before joining the University of East Anglia (UEA) in 2007, most of my PostDoc research was conducted with a fellowship from the German Academic Exchange Service (DAAD) in the School of Oceanography, University of Washington (E.V. Armbrust lab) in joint cooperation with the Biotechnology Center, University of Wisconsin (M.R. Sussman lab), USA. Before I was promoted to Professor in 2014, I was Reader (2012-2014) and had a Research Councils UK (RCUK) Academic Fellowship (2007-2012). I am a member of several genome and metagenome projects with marine microalgae (e.g. diatoms) and bacteria and conducted transcriptome analysis with diatoms using microarrays and expressed sequence tags (ESTs) in order to find the molecular basis of adaptation to environmental conditions. A crucial part of this research is the identification of metabolic pathways (e.g carbon fixation, silicon bioprocesses in diatoms) and their key regulatory components (e.g. DNA-binding proteins) to find mechanisms on how these organisms sense changes in environmental conditions. This fundamental knowledge about microbes from the upper ocean will help to interpret future responses to global change.

Dr Nigel Belshaw
After obtaining a degree in Biochemistry from the University of East Anglia (UEA) I studied for a PhD on the regulation of gene expression in filamentous fungi at the Institute of Food Research (IFR) in the Norwich Research Park. This project and my subsequent research were focussed on the role of chromatin structure and epigenetic modifications as regulators of gene expression. Until recently I led a team at IFR investigating the role of epigenetics in gut disease and the influence of lifestyle factors. In my current role I will be developing and utilising the CRISPR/Cas genome editing tool to understand gene function in the polar diatom Fragilariopsis cylindrus.
Dr Irina Grouneva
Diatoms have been the main focus of my research for more than ten years. My areas of expertise are physiology, proteomics and molecular biology. I obtained my PhD in Biology at the University of Leipzig, Germany in 2009 and went on to work as a postdoc in the group of Prof. Eva-Mari Aro at the University of Turku, Finland for six years. I moved to Norwich in April 2016 to start work on an exciting new project on gene editing of the ice diatom Fragilariopsis cylindrus in the lab of Professor Thomas Mock at the University of East Anglia (UEA). The objective is to establish the recently developed CRISPR/Cas-mediated gene editing tool in this diatom species. The novelty of this approach lies with the possibility to generate complete knockouts for specific target genes, something that has not been possible in diatoms previously. F. cylindrus is the first fully sequenced psychrophilic eukaryote and can therefore provide invaluable insights into cold-adaptation of eukaryotic photosynthesis.

Dr. Amanda Hopes
I finished my PhD in Thomas Mock’s group in 2017, working on developing new molecular tools for diatoms and investigating the function of a gene potentially involved in regulating silica metabolism in the polar diatom Fragilariopsis cylindrus. During this time, I developed a transformation system for F. cylindrus, CRISPR-Cas using a Golden-Gate approach for gene-editing in the model diatom Thalassiosira pseudonana and started development of an Inverse yeast 1-hybrid system for F. cylindrus.
Prior to my PhD I worked for a biotechnology company for four and half years as a researcher, developing molecular clinical diagnostic tools.
Following my PhD I started a short- term NRP Post-Doc investing protein regulation in T. pseudonana through ribosome profiling and adapting codon usage using CRISPR-driven homologous recombination developed in the Mock lab.
I have just started my second Post-Doc with Thomas researching the molecular underpinnings of adaptive evolution in polar diatoms.

Dr. Andrew Toseland
My degree in Software Engineering at UWE Bristol focused on Object Oriented design and programming in Java. My main interests lay in Computer Science topics, particularly machine learning, which was the focus of my final year project. My PhD is focused on a computational analysis of marine eukaryote metatranscriptome data using Perl and published bioinformatics tools to develop an analysis pipeline.

Bioinformatics approaches for assessing the impact of temperature on eukaryotic phytoplankton
I graduated from the University College Dublin (UCD) with a degree in Science, majoring in Microbiology in 2011. My final year project was 'Investigating the role of sigma factor in physiology of Rhodococcus equi.' I then went to pursue a masters and graduated with a MSc. in Bioinformatics from University of Leicester in 2012. My final year project for my masters was 'In silico mining for microsatellites'. I gained research experience in bioinformatics at the National Institute for Cellular Biotechnology (NICB). The role involved statistical analysis of microarray data generated from colorectal cancer samples conducted within the R/Bioconductor software environment.
I am currently in my first year of my PhD. My project is "Bioinformatics approaches for assessing the impact of temperature on eukaryotic phytoplankton".

Professor Thomas Mock
I studied Biology at the University of Santiago de Compostela, where I majored in Molecular Biology and Biotechnology. My interest in the application of Biotechnology in the environment drove me to study for an MSc in Biotechnology for a Sustainable Future at the University of East Anglia (UEA). My Master's research project in the group of Dr Jonathan Todd focused on how Thalossiosira pseudonana, a model marine diatom, synthesises glycine betaine, the most abundant osmolyte in nature.
After my masters, I became a Senior Research Technician in the research groups of Dr Jonathan Todd and Professor Thomas Mock. My project involved dimethylsulphoniopropionate (DMSP) synthesis in phytoplankton, as well as continuing the work on glycine betaine synthesis from my Master's project.
In my current PhD project, I am taking a step further in the glycine betaine synthesis research in diatoms, as well as using these new findings for the improvement of key agricultural crops.

I studied Infectious Diseases with a focus on microbiology at the University of Edinburgh and graduated in 2015. My honours project was genetic identification of zoonotic trypanosomiasis strains in cattle, which sparked my interest in genomics and bioinformatics. I completed an MSc in Bioinformatics, also at the University of Edinburgh, in 2017. My MSc research project mainly involved genome assembly and analysis, I also created a genomic database and browser and performed DNA sequencing using the Nanopore MinION portable real-time long read sequencer. In October 2017 I moved to Norwich to begin a PhD at the UEA. My project is focussed on using the Nanopore MinION for real-time metagenomic sequencing of polar ocean samples to monitor polar microbe populations.
