RESEARCH AREA OF INTEREST
The candidate follows the scientific school that fervors breeding and improvement of productive and
reproductive traits for both animals and poultry, especially the native ones.
This objective could be achieved through using modern biotechnological techniques. A quantitative
genetic breeding program should be developed (designed) with continuous backcrossing and subsequent
complete laboratory screening to avoid undesirable or point mutations.
Moreover, genetic diversity and transgenesis would be practiced on different animal and poultry classes,
in order to define the best solutions environmentally and genetically to maximize the performance.
