I am a double Hungarian-Romanian citizen and I did my undergraduate studies in Cluj-Napoca/Kolozsvár, Romania, at the Babes-Bolyai University. It is worth mentioning that some famous Hungarian mathematicians (such as Riesz, Fejér, Farkas, Haar) were teaching and doing research at this university before the World War I, so it has been a nice experience walking in their footsteps. After finishing my BSc, I spent one year as an exchange student at the Technical University of Dortmund, Germany. During this year I realized that I want to pursue a PhD in the field of Partial Differential Equations (PDEs). I am very thankful to FMJH for funding my year of M2 on Mathematical Modeling and in particular on PDEs offered by the École Polytechnique and Université Paris-Sud. I realized quite soon that Paris is one of the best places on Earth to study mathematics. The professors gave insight to the high level up to date research, I could attend many research seminars and workshops. Next I was lucky to start a PhD under the supervision of Filippo Santambrogio at the Laboratoire de Mathématiques d'Orsay, Université Paris-Sud. He gave me a very nice set of problems entering in the theories of PDEs, optimal transportation and the recently introduced theory of Mean Field Games (MFG). This last one, introduced by J.-M. Lasry and P.-L. Lions, uses ideas from PDEs and statistical physics to study differential games with a very large number of players. In my thesis I studied different models under congestion effects, i.e., with a constraint on the density of the agents. Right after my defense I started as a postdoc (assistant adjunct professor) at UCLA in the United States. Here I give lectures to undergraduate students and I continue my research on optimal transport and MFG. In the future I would like to develop my career at the academia in a stimulating research environment.
I did my undergraduate studies and my first year of Master at the Université Paris-Diderot. Thanks to the FMJH funding, I completed my second year of Master in Probability and Statistics at the Laboratoire de Mathématiques d'Orsay at the Université Paris-Sud. This year gave me a high-level training in Probabilities that I could not have accessed without this grant. The Master coordinator introduced me to Jean Bertoin who supervised my PhD at the University of Zurich, Switzerland, on the subject Random trees, fires and non-crossing partitions. The first part of my thesis deals with fire dynamics on large random trees, I studied in particular the sizes of the burnt and fireproof connected components as the size of the tree tends to infinity. I have currently a post-doc position at the Université Pierre et Marie Curie funded by the Fondation Science Mathématiques de Paris. I work mainly with Thomas Duquesne on fine geometric and fractal properties of Lévy trees that represent roughly the genealogy of a large population in which each individual reproduces at random, independently of each other. After my postdoc, I would like to get an academic position.
I did all my studies in the Paris region, beginning with a double bachelor degree in Mathematics and Physics at the University of Versailles Saint Quentin (UVSQ). Next I completed my first year of master degree in mathematical engineering, majoring in modelling at University of Paris Sud and the second year in modelling and simulation at the UVSQ. This last year was funded by the FMJH. The scolarship allowed me to pay off a part of my student loan and to finance my second year internship at Dublin, Ireland. I am currently doing the last year of my PhD thesis at the Centre de Mathématiques et de Leurs Applications at the ENS Cachan, under the supervision of Florian De Vuyst. I work on elaborating numerical methods for modelling multiphase flows with high density ratio, of type air-water. At the end of my PhD, I would like to find a research and development position in a company in the continuity of my current research interests.

I am currently a PhD student in laboratoire de Mathématiques d'Orsay in Université Paris-sud. I am interested in doing research in mathematical sciences, more precisely in statistics. Previously, I was in Senegal where I have had a master 1 degree in probability and statistics at Université Gaston Berger before doing a master degree in mathematical sciences at AIMS-Senegal. After my master, I had the FMJH scholarship for doing a master's degree at Paris-sud university. Next, I had a scholarship in the same university for doing my thesis in statistics "Spectral Method for Mixtures of GLM". Indeed, I have some data providing by Institut Pasteur de Dakar in Senegal, and the challenge is to give a tool of diagnosis for the coinfection between two illness which have clinical resemblance. So we use a mixture of multinomial logit model not with EM algorithm but a tensor method. After my thesis, I would like to have one or two year experience on post-doctoral research before doing a job researchers in a university, in preference in Senegal.
After obtaining my Bachelor’s degree of mathematics and statistics, I continued my study in China as a first year graduate student, majoring in mathematics and probabilities. Attracted by the education of high quality in France, I made a big decision: I stopped my study in China and came to Ecole Polytechnique as a first year master in applied mathematics, funded by the FMJH. The courses offered in Ecole polytechniques are not easy, and my limitation in French at the beginning makes it even harder. But these courses did broaden my eyes: They covers a lot of domains and offer me a valuable opportunity to find where my true interests are, and prepare me for them. In addition, I did a four-months internship in data analysis in INRA, which enabled me to deepen my knowledge and also lead me to the world of data analysis. At the end, I decided to continue my second year master in Data Science at university Paris-Saclay and became beneficiary of FMJH again. Data Science is now a prosperous area where new challenges, techniques and possibilities keep emerging. Attracted by its great development potential in industry, I decide to work in Pairs after my graduation. I am planning to do my end-of-year internship at Air Liquide Research Center in marketing data analysis. I hope that this internship could prepare me for my future.
