I am a supervisor of Alexander and I have known him for six years. I can describe him as a person who is persistent in achieving his stated goals and capable of serious analytical work. He is well-versed in the area of his scientific research and able to conduct independent research.
It should be noted he has a teaching talenttalent for teaching. Alexander conducted seminars on philosophy of law and established himself as a capable teacher. I gave lectures on which he conducted seminars and I must say that Alexander perfectly understood the issues that were discussed during the course. He was able to clearly explain the points that caused the most trouble to students at the seminars. Examination showed that Alexander coped with his task perfectly.
One of his most important features abilities is the ability for creative thinking. His work indicates that he is interested in the study of philosophical problems and is aimed at self-study.
Alexander has good communication skills and actively participates in discussions.
I believe that the skills and personal qualities of Alexander let me recommend him to participate in the program. I hope that studying in the Institute of Culture will help him to pursue his research.
