Jabrane Labidi - The black lives matter movement - challenging anti-black racism in academia

BLACK LIVES MATTER -  challenging the status quo in academia  In the wake of the murder of George Floyd and Breonna Taylor, academics must challenge their bias against our black peers. In this excellent, gut-wrenching piece,  here (absolute read), Charles D. Brown II shows that less than 2% of earth science bachelor's degrees in the US went to black students in 2017, the lowest rates among all STEM fields. The statistics do not exist in Europe due to a regressive legislation, but it would be reasonable to assume the numbers are comparable, at best, or probably even less favorable to black folxs in academia.  The geochemical society, through the leadership of Roberta Rudnick, decided to take a stand, which i commend. For the online goldschmidt of 2020, a town hall about racism was organized, and i had the privilege to say a few words about our issues in academia, and specifically in our field. I was joined by three brilliant early career scientists: Emily Cooperdock (USC), James Do

Jabrane Labidi - DEI effort at the EAG

Image
I enthusiastically joined the Diversity, Equality, and Inclusion sub-group at the European Association of Geochemistry. Our goal will be to  "promote DEI initiatives that cultivate welcoming, kind, inspiring, and actively anti-discriminatory scientific cultures as well as safe, healthy, and supportive working environments. As such, the EAG DEI initiative shall serve as a model for STEM in optimizing participation of historically excluded and underrepresented peoples across all sectors, levels of employ, and positions of community leadership." This is an initiative to tackle racism and other biases in our academic circles. We hope to not only raise awareness on how gated geochemistry appears to be for underrepresented folks, but also to produce content describing key aspects of our problem at hand. We intend on discussing the intricate aspects of social reproduction within academia on a worldwide scale, but also with a special target on European institutions. We will host a n

Nitrogen isotopologues reveal the origin of nitrogen in our planetary interior - Jabrane Labidi

Hi All,  We've published our work in the journal Nature. We show that we can eliminate the confounding effect of air contamination in volcanic and hydrothermal gases, for the specific case of nitrogen. By substracting air contamination, we derive the di-nitrogen (N 2 ) molecular weight in various mantle sources.  A new finding here is that various mantle sources, with variable 15N/14N ratios, have a near-constant N2/3He ratio. Because 3He is in the deep Earth is not recycled, the constant N2/3He ratios argue against nitrogen addition via subduction in various mantle sources.  We built a 2-box model to show how over 4.5 Ga, the mantle and air may have exchanged considerably less nitrogen than previously suggested. In other words, the possibility that mantle nitrogen is primordial can no longer be excluced. In this theory, nitrogen would have been inherited from the time the Earth was being built via planetary accretion.  proud of this work! Here is a link to vi
