The Aquila consortium
I am a member of the Aquila consortium, which we have founded in 2016. Our public website is now online. Go and check it out !
Automatic physically motivated inference
We have submitted a new article to find optimal non-linear compression techniques of data, in the objective to do Bayesian inference, based on Artificial Neural Networks. In the work we present the Neural Network explores itself the space of all functions that can extract relevant information based on physically based simulations.
Upgraded website for Cosmicflows
The CosmicFlows website has many new features that got inserted in the last year, including online query of modelled distances and an interactive local universe explorer. Please check them out!
New website for the BIG4 project
I have started a new website for the project BIG4, for which I am the Principal Investigator. Please visit it at big4.iap.fr and check documentation and videos.
Constraints on Cosmology and Gravity from the Dynamics of Voids
I have submitted an article to MNRAS on using the ARES/BORG machinery as a telescope to detect and characterize large scale structures. On this pictures one can see some of the results, without particular ordering: density field inference, galaxy bias measurement, error estimation, ... The work is based on my 2M++ galaxy compilation.
Graduated Ph.D. at Institut d''Astrophysique de Paris. Ph.D. subject: "Reconstruction of primordial density fluctuations" Advisors: R. Mohayaee, S. Colombi, F. Bernardeau, J. Silk
I have also taught to first year university students the concepts of mechanics through energy conservation. This teaching was accomplished through tutorial lessons.
From September 2008 to August 2011, I was a post-doctoral research fellow at the University of Illinois at Urbana-Champaign in the department of Astronomy. There I have an ongoing collaboration with Professor Benjamin Wandelt on the subject of the formation of Large Scale structures and new methods to analyze CMB data.
From September 2011 to April 2013, I was a CITA national fellow to University of Waterloo in Ontario, Canada. I was also a post-doctoral associate at the Perimeter Institute.
Since May 2013, I am a full time researcher at the Institut d'Astrophysique de Paris.
