Biography
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.

Biography
I obtained an MSci from University College London in Genetics, Evolution and Environment, undertaking a research project on the evolution of Apicomplexa. I am currently employed at the Mock Lab researching a method of obtaining cell free DNA from aquatic environment using CRISPR-Cas9. In October 2019 I am due to start a PhD in phytoplankton genetics. The polar phytoplankton Fragilariopsis cylindrus has been shown to an unusual biallelic expression in response to the seasonal variation in environmental conditions. I will be researching the molecular mechanisms that that cause this, whether this is unique in F. cylindrus, and what is the significance for this on its evolution.

Biography
I graduated from the University of North Carolina Wilmington (UNCW), in July 2017 with a degree in Marine Biology. During my undergraduate studies at UNCW, I served as a research intern at the Sea Turtle Protection Program, Bald Head Island, North Carolina, where I studied epibiotic communities on the carapaces of nesting sea turtles. As an undergraduate, I became increasingly fascinated in marine phytoplankton, specifically diatoms, and their ability to adapt to different environmental conditions. Following graduation I returned home to the UK, working first as Research Assistant within a team at the University of Cambridge studying gene expression and methylation patterns in neonatal and adult stem cells. I then moved to begin my graduate studies at UEA where I am currently in the first year studying for my PhD with Professor Mock. The focus of my research is the use of reverse gene editing methods to further understand the adaptive evolution of the model polar diatom Fragilariopsis cylindrus.

Post-Doctoral Researcher
Email: a.hopes@uea.ac.uk
Biography
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.

Biography
During my B.Sc. degree in biology at the University of Bremen, Germany, I studied Trypanosoma sp., the pathogen causing African sleeping sickness in livestock and humans. To look at the transmitting tsetse fly and bacteria present in its gut will help to understand how infections are established, and eventually to identify potential points of intervention. Seeing the importance and benefits that molecular life sciences can have on health and the environment, I decided to continue research at the interface of molecular and environmental biology in collaboration with the Alfred Wegener Institute in Bremerhaven during my M.Sc. in Biochemistry and Molecular Biology. In my master’s project, I analysed metatranscriptomic data from a harmful algal bloom (HAB) to identify cellular processes and enzymes involved in the formation of HABs and the associated toxicity. Following up on the use of molecular analyses to understand marine organisms, I started my PhD in October 2022 and will study the role of mitotic recombination in genome evolution of polar phytoplankton.

Biography
I have completed my Master in Geobiology and Paleobiology, with an emphasis on Geomicrobiology, at the University of Munich. Through my research projects I have gained experience in high-throughput sequencing and bioinformatics for bacterial and eukaryotic diversity studies. For my PhD project at UEA, I apply ribosome profiling to reveal how temperature, which is one of the most important growth factors, affects translation in diatoms. Furthermore, I use CRISPR/Cas9 in combination with ribosome profiling to provide insights how codon usage, tRNA abundance and tRNA- derived small non-coding RNAs impact protein synthesis in the model diatom Thalassiosira pseudonana under changing environmental conditions.

I obtained my BA (Hons) in Natural Sciences from the University of Cambridge, graduating in 2020. During my undergraduate degree, I pursued a variety of interests, ranging from cell and developmental biology to ecology and evolution. This piqued my interest in environmental microbiology, and I furthered this by embarking on a research project in northwestern Canada, using shotgun metagenomics to explore how permafrost thaw affects microbes in thermokarst lake sediments. Following this, I became interested in applying microbiology to solve global challenges, and to this end undertook an MSc by research at the University of Exeter in the Exeter Microbial Biofuels Group. I then decided to turn to the intersection of biotechnology and microbial physiology, ecology and evolution, through a PhD at UEA supervised by Professor Mock. I began my studies in October 2021, and my research aims to understand at the function of ice-binding protein diversity in the polar diatom F. cylindrus.

Biography
I started my Postgraduate and Doctoral Program at Ocean University of China (OUC) in 2016, majoring in hydrobiology. During this time, I have conducted research on the hemostatic ability of diatom frustules (Thalassiosira weissflogii, Thalassiosira sp., Cyclotella cryptica, Cocconeiopsis orthoneoides, Navicula avium, Navicula sp., and Pleurosigma indicum) which can be utilized as a natural bio-silica material. I found that the unique physical properties of frustule (specific surface area, size, pore diameter) would influence its ability to concentrate coagulation components and activate the coagulation cascade pathway, and therefore play an important role in determining its hemostatic properties. Thus, I tried to manipulate morphology of C. cryptica frustule through regulating CcSAP3 expression (gene over expression and RNA antisense).
Following this, I became interested in the synthesis of diatom cell wall. I began my studies in Mock lab in June 2022, and my research aims to find new genes/proteins regulating T. pseudonana cell size through RNA-seq and verify their function using CRISPR-CAS.
Research interests
