| RESEARCH INTERESTS | |
|
My research interests are oriented towards the interpretation of Large Scale
Genomic Data, and the use of computational methods in order to reveal the
principles governing the Molecular Basis of Life. In particular, I am mainly
interested in the elucidation of protein sequence to structure/function
relationships by statistical and machine learning techniques.
1. Sequence repeats, low complexity/compositionally biased regions - Relation to protein structure - Assosiation to protein (mis)function - Evolution of protein repeats - Correlation to the nucleic acid sequence features 2. Transmembrane Protein topology and structure prediction - Prediction of structrural features of membrane proteins - Evolution of transmembrane protein topology/structure/function 3. Sequence-based structural/functional classification of proteins 4. Computer-aided and automatic Genome Annotation | |
