Hamza El Bouhargani
Hamza started as a Master 2 student doing his Master thesis work as part of the B3DCMB project. On finishing his Master courses in September 2018 he become a PhD student and continues working with us. His area of interest are methods suitable for on the map-making problem. He is also a member of the Simons Array and Simons Observatory experiments.
Baptiste Jost (TBF)
Baptiste started as a Master 2 student at the APC Laboratory and will transition to a PhD status from Oct 1, 2019. His interests are in novel techniques for the scientific exploitation of the CMB data sets. He is a member of the Simons Array and Simons Observatory experiments. Baptiste is supported by an international studentship from CNRS and will spend significant time during his PhD in Berkeley working in the group of prof. A. T. Lee.
Aygul Jamal
Aygul is a postdoctoral researcher who will join the B3DCMB project staring on November 1, 2018. Aygul received her PhD degree in computer science from the Paris-Sud University. She is an expert in solving, large linear systems of equations and looks forward to applying them to the CMB data analysis problems.
Clemént Leloup
