In 2022, TBI has been awarded two Junior Professorships allowing to recruit two scientists who have already demonstrated their ability to produce excellent research. The themes studied by these scientists show the richness and breadth of research conducted at the laboratory. Meet Lorie Hamelin, laureate of the INRAE chair dedicated to supporting sustainable and intelligent transitions towards tomorrow's low-fossil carbon economies; and Christophe Danelon, winner of the INSA \"synthetic cells\" chair.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

I completed my master's degree and engineering studies in agricultural engineering at Laval University in Canada. I then pursued a PhD at the University of Southern Denmark, where my research focused on evaluating the role of biomass in a sustainable Danish strategy to achieve 100% renewable energy by 2050. After completing my PhD, I took on a post-doc position and later became an assistant professor at the same University. Within the framework of\u00a0the ERA Chair1 program<\/a>funded by the European Union, I spent a year in Poland working to strengthen research capabilities in the field of bioeconomy. In 2018, I was selected as a recipient of the French MOPGA program , allowing me to be Principal Investigator on the Cambioscop<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

I am an expert in environmental analysis with the life cycle assessment (LCA) methodology. My expertise is at the interface between environmental engineering, renewable energy systems, circular economy and bioeconomy. I am interested in major system transitions and in particular in the transition to a low fossil carbon economy, a must to reach the Paris agreement goals. I also have a strong expertise in agro-ecology due to my training in agricultural engineering.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The Chair focuses on transitions towards a low-fossil carbon economies. It has 3 main research axes: (1) Inducing additional carbon sequestration (negative emissions), (2) leaving fossil resources in the ground, (3) developing sustainable alternatives to fossil resources.<\/p>

The first axis involves studying the potential for carbon sequestration in agricultural soils, in particular through the use of cover crops on bare soils, examining the environmental impacts of different strategies for utilizing the biomass generated by these crops (e.g. incorporation of the biomass to soils as green manure or harvesting it completely or partially for e.g. biogas or bio-materials production).<\/p>

The second axis aims to improve the understanding of decision making by bioeconomy stakeholders, particularly in regards to the use of the information supplied by life cycle assessments. I here envision to derive a few\nkey performance indicators that are relevant to the actors in the sectors concerned by the transition to a low-carbon fossil economy, which could vary according to the sector and the territory. I envisage conducting interviews to determine whether stakeholders understand the indicators and prospective scenarios currently used, whether they consider them relevant for decision-making, and whether they are considering other indicators and scenarios. The vision is to ensure that technological solutions are translated into a real societal project, and to identify and address the non-technological barriers that stand in the way of this transition to a low-carbon fossil economy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

This Chair is a position that lasts for 3 years and, upon successful evaluation, can lead to a \u2018DR2\u2019 tenure at INRAE. I am affiliated with the SOPHYE<\/a>team at TBI. The Chair includes teaching duties (up to 42h per year), primarily at INSA Toulouse, within the GP3E department. The research of the Chair will be connected to my other ongoing projects (e.g. ALIGNED<\/a>, NEGEM<\/a>, Solnovo<\/a>). The financial support associated with the Chair (ANR, INRAE), will allow me to hire and train young scientists to work on the different axes of the Chair, and to cover the expenses related to the research progress.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

I am committed to contributing to research that will allow, even if it is a drop in the ocean, limiting global warming below 2\u00b0C, with a minimum of trade-offs with the other environmental impacts. My future research will continue to focus on finding solutions to (i) keep fossil carbon in the ground, (ii) develop sustainable alternatives to replace fossil carbon, and (iii) induce negative emissions (long-term sequestration of atmospheric carbon). I also hope to contribute to a certain harmonization of the LCA methodology and bring methodological advancements, particularly in regards to its application to bio-based products and services, as there is currently some confusion that could undermine the credibility of the method.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

I am a former student of the University of Paul Sabatier in Toulouse and I did my thesis in biophysics at the IPBS. Then, I spent 6 years at the \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne in Switzerland as a post-doc and as a teacher-researcher. In January 2010, I was appointed as an assistant professor at the University of Delft in the Netherlands, where I set up my laboratory on the topic of synthetic cells.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

My activities are focused on synthetic biology, more particularly on a field called \"cell-free\" or outside the cell frame. We do molecular and cellular engineering but outside a living cell. Other important components of our research include molecular, membrane and cell biophysics. This discipline is part of my scientific culture and I apply it in quantitative biology for example. Or in computational modeling or the use of advanced methods in analytical microscopy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Yes, I am also in charge of an iGEM team in the Netherlands and I will now participate in the coaching of the iGEM Toulouse team. It is also through iGEM that I started to identify and get interested in TBI and INSA Toulouse. The beautiful results of iGEM Toulouse these last years made me quite curious about the research work in synthetic biology carried out at TBI. It is a nice showcase for the laboratory and it is something that stimulated my curiosity to approach TBI and see if there were possibilities to join the laboratory.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

It is a project that aims at recreating a living cell, in line with the research that I have been carrying out for almost 13 years. One of the strong pillars of our approach is the use of lipid vesicles that act as a compartment. Then we encapsulate inside this vesicle a coding DNA to have all the biological functions encoded in genes. So, we have a compartment, we have DNA which serves as a support for heredity and evolution, and we have a machinery which converts the genetic program into proteins that realize essential cellular functions, such as the synthesis of phospholipids for vesicle growth. But also all the proteins that are involved in DNA replication and in the division of the vesicle. We call these 'modules', key biological functions that we are trying to reconstitute.<\/p>

Our innovative strategy now, and the environment at TBI is conducive to develop this type of project, is declined on 2 axes:<\/p>
