Academic Profile

There are many computational problems in Biology that can be represented as Combinatorial Optimization Problems. Many tools and algorithms available to solve these problems are not effective or efficient enough, sometimes because they do not produce optimal solutions or because they are only capable of solving a high level abstraction of the real problem.

Using Artificial Intelligence methods such as Constraint Programming, Local Search, Large Neighborhood Search, etc., these approaches can be greatly improved.We have applied these techniques with considerable success to problems such as protein structure prediction, riboswitch energy barrier calculation, RNA segmentation and Between Pathway Models discovery.
