7 Septembre 2021


Catégorie : Post-doctorant


Dear Colleagues,

 
We are looking for a postdoctoral fellow in Machine Learning applied to Biology.
 
The topic concerns Temporal Data Integration and aims at combining high dimensional time series obtained from various acquisition techniques to study developing embryos.
 
The successful candidate will work jointly within Paul Villoutreix’s interdisciplinary group (http://bioml.lis-lab.fr/) and under the supervision of Thierry Artières within the Machine Learning team of the Computer Science lab in Marseille (https://qarma.lis-lab.fr).
 
The position is part of the Turing Center for Living Systems (https://centuri-livingsystems.org), which is a vibrant interdisciplinary community composed of mathematicians, computer scientists, physicists, …, interested in questions of biology in Marseille, France.
 
We are looking for a candidate with a PhD in machine learning, computer science, applied mathematics with strong interest in machine learning and its applications to biology.
 
More details in the document attached.
 
Best wishes,
 
Paul Villoutreix
 

 

Project description

When studying a biological system such as a developing embryo, many acquisition techniques are available. Each of them brings out unique features of the system, however, they are often incompatible and cannot be performed at the same time. To address this challenge we need to develop multi-domain integration techniques. Current approaches rely either on the tools of optimal transport, or multiple autoencoders, however, they are not designed to address temporal data. With this project, we propose to take advantage of multi-domain dynamical data in high-dimensional spaces to infer a dynamical coupling between sequencing data acquisition techniques (such as sc-RNASeq) and microscopy data. This will include theoretical work and computational experiments on artificial and real data. The results of the project are expected to have large impact in the machine learning community and be of wide applicability in real world biological problems. The scientific environment for this project is ideal as it combines expertise in interdisciplinary approaches of machine learning applied to biological data, and expertise in theoretical machine learning.
