Abigail Conner:
Student Team Leader
Abigail served as the Student Team Leader alongside Stephanie Avraamides. She has been working on this project since she returned from the Jamboree last November. Last year, she hosted the recruitment talks to spread the word about iGEM at King’s and eventually selected this year’s team alongside Stephanie by reading through dozens of applications and hosting interviews. In early 2020, she and Stephanie additionally began the process of founding a Biotechnology and Synthetic Biology society within King’s College London’s Student Union (KCLSU). Through the KCLSU society, our team will implement our Biologix competition and will collaborate with several other societies to further discussions of Synthetic Biology and our university. Abigail was pivotal in the design of our project and originated the concept of a scaffold with a mussel-foot protein based bioadhesive from her research into tissue engineering and bioglues at the start of the year. Throughout 2020, she and Stephanie guided the team throughout the COVID-19 pandemic and ensured that our project adapted to an in silico approach. In this regard, she guided the work regarding the mussel foot protein and worked closely with our collaborators and supervisors. However, she worked closely with each subgroup to ensure that all tasks were completed and that medal criteria were being achieved. Outside of the scientific work, Abigail applied to and secured the highly competitive Promega grant, which ensured that our team could participate in the 2020 iGEM Competition. As a member of last year’s team, Abigail was responsible for the completion of the Wiki, and carried these skills through to this year. Her proudest accomplishment of this year is coding a responsive drop down menu bar, which she was unable to do last year. Outside of the menu bar, she was responsible for the overarching design of the Wiki and hosted weekly sessions to teach other team members how to code in CSS and HTML.
Stephanie Avraamides:
Student Team Leader
Stephanie Avraamides was the Student Team Leader of Renervate. Alongside Abigail Conner, she has worked on the project since the end of 2019 and recruited, interviewed and led the team and orchestrated Renervate. Stephanie co-founded the KCLSU Biotechnology and Synthetic Biology Society to continue the legacy of the Biologix competition, recruit members for future iGEM teams and increase the presence of student-driven synbio community at King’s College London. Stephanie alongside Abigail investigated and strategized the project, tailoring Renervate from a laboratory-based project to an in silico project that could be completed by team members based internationally due to the COVID-19 pandemic. Stephanie was pivotal in finding the optimal approach for our chosen subset of patients, which led to the idea formation through the converging of synthetic biology with Bioprinting. She was instrumental in designing a personalised 3D bioprinted approach for Spinal Cord Injury, which included the research and validation of the scaffold specifications to optimise the personalised scaffold in line with our human practises work, material choice, and the implementation of the micro and macro-architecture, determined through modelling. As the Team Leader, she played a key role in the role allocation, strategic planning and orchestration of the scientific and additional sub-teams, including the inclusivity team, proposed implementation & entrepreneurship team, working with other iGEM teams for collaboration and orchestrating the therapeutics meet up. Stephanie has pitched Renervate to those who helped to shape our project during our wide-reaching Human Practises Interviews and played an active role in integrating our human practises feedback to optimally shape our project. Subsequently, Stephanie has organised science communication campaigns and opportunities, including pioneering the Biologix competition. Stephanie has corresponded with and secured sponsors for the KCL iGEM 2020 team.
