Evolution of the Genetic Code

The development of the genetic code's initial and middle phases might have been shaped by pressures unrelated to its role in protein translation. I am investigating the resilience of early-stage genetic codes to mutations, focusing on codes of varying complexity. My objective is to determine at what level of complexity the genetic code starts transitioning towards its definitive functional role.


In the past decade, the use of high throughput sequencing (HTS) for analyzing DNA and RNA molecules in in vitro evolution experiments has seen a significant rise. My current focus is on the development and application of bioinformatic tools for processing and interpreting HTS data.

Fitness Landscapes

The concept of a fitness landscape represents the relationship between fitness (or molecular activity) and all possible genetic sequences. Evolution navigates this landscape, aiming to reach higher peaks of fitness. This journey can be envisioned as a biased random walk on the fitness landscape, favoring upward movement. To deepen our understanding of evolution, I am creating and utilizing computational methods to depict and study fitness landscapes, drawing on sequencing data from evolutionary studies.

Mathematical modeling of biological systems

I am passionate about applying mathematics to describe nature. Most of my work in this realm relates to modeling and simulating a wide variety of biological systems and processes, ranging from protocells to phage-bacteria interactions.

As Albert Einstein pointed out, How is it possible that mathematics, a product of human thought that is independent of experience, fits so excellently the objects of reality?

Molecular Homochirality

It is an empirical fact that amino acids appear almost exclusively in the left-handed form (L-amino acids) and sugars in the right-handed form (R-sugars) in biological organisms. The emergence of homochirality in the molecules of life remains a mystery for modern science and we are still far from having plausible theories to explain its origin. My work in this field has been dedicated to the unveiling of the fundamental aspects of the onset, emergence, amplification and transmission of chiral asymmetry at the molecular and supramolecular levels.
