I was born and raised in a beautiful Eastern European country called Romania. My hometown, Constanta (almost 300 000 inhabitants), is one of the largest cities in the country and it was founded around 600 BC. Its location is on the Black Sea coast and the Port of Constanta is the largest in the area as well as the 4th largest port in Europe after Rotterdam, Antwerp and Marseille.
Below, you can see some photos of my lovely hometown.



After I graduated from high school I moved to Bucharest, the capital and the largest city (almost 2 million inhabitants) of Romania. The city is situated on the banks of Dambovita river and like other Romanian cities it has a rich history and culture. Bucharest is the 6th largest city in the European Union by population within city limits, after London, Berlin, Madrid, Rome, and Paris.

Here I did my undergraduate (mathematics and computer science) and masters (algebra and number theory) studies at the University of Bucharest (Faculty of Mathematics and Computer Science), my alma mater. The department of mathematics is world renowned for its schools of Analysis and Differential Equations which produced many famous mathematicians over the past 50 years who are faculty in the some of the most prestigious universities around US and Europe.
My bachelor thesis was titled Topological Degree for Condensing Maps  and my masters diploma on Landau and Hardy-Littlewood type inequalities for the prime counting function \pi(x). Meanwhile, I was accepted as a Ph.D. student at University of Craiova under the supervision of Dr. Vicentiu Radulescu. I completed the program in 2013 with a thesis in Nonlinear Analysis, Qualitative Analysis of some Classes of Nonlinear Problems. Also, between 2009 and 2011 I was appointed as a teaching assistant in the Mathematical Methods and Models department at Politehnica University of Bucharest. My teaching duties included teaching recitations of analysis, linear algebra and differential equations for engineers. Moreover, I was also involved in training the best undergraduate students for national and international competitions.



In 2012, I moved to Pittsburgh (Pennsylvania), United States for doctoral studies at the University of Pittsburgh. The city of Pittsburgh, also called “The steel city” or “The city of bridges”, is considered by many the most livable city in the USA. Pittsburgh is renowned for innovation over the past years being home to some of the finest universities in the world. The University of Pittsburgh is one of the oldest institutions in the country.

I graduated with a masters of arts diploma in 2014, and currently, I am a 6th year Ph.D. student in the department of mathematics under the supervision of Dr. Piotr Hajlasz and Dr. William C. Troy. My research focuses on topics in real and geometric analysis, number theory and special functions. Currently, I am working on geometric properties of rectifiable curves in the Heisenberg group, connections between Marcinkiewicz integral operators and Sobolev spaces and on analytic aspects of the Riemann zeta and multiple zeta values. On the other hand, I am also involved in teaching lower and upper level math classes. Moreover, between 2013-2017, I helped in organizing and training the best Pitt students for the most important undergraduate math competition: The William Lowell Putnam Competition.



Between 2015-2018, I was hired as an instructor in the Mathematical Olympiad Summer Program (MOP) which is designed to train the best high school students in US for the International Mathematical Olympiad You can see below some pictures with the city and the university’s campus.

In my free time, I enjoy playing football (soccer), chess, tennis, skiing, go-karting and many other sports, but also watching movies, astrophysics and history documentaries. In addition, I am a travel addict. I like getting to explore other cultures and learn about the histories of different countries. So far, I have visited 15 countries, all European except the USA.
