Research Projects

Protein Structure Prediction

Proteins are polypeptide chains carrying out most of the basic functions of life at the molecular level. These linear chains fold in complex 3D structures whose shape is responsible of proteins' behavior. Thanks to several genome sequencing projects, the entire DNA sequence of many organisms has been experimentally determined, and millions of proteins sequences identified. However, physical methods, such as NMR and crystallography, are not able to cope with this incredible number of structures, and most of these proteins' 3D structures and functions remain unknown. Therefore, it is becoming increasingly important to predict protein's tertiary structure ab initio from its amino acid sequence, using insights obtained from already known structures.

Adaptive processing of data structures

Connectionist and probabilistic models for machine learning are often limited to processing relatively poor data types. While some domains naturally lead to static data representations, other domains are better described by variable length representations. However, data in the real world often come with a much richer structure and serial order can be generalized to more complex relations. These relations can be naturally represented by graphs. While neural network and probabilistic architectures have been extensively studied for both static and sequential data types, architectures for data structures have received relatively little attention until recently.
