Roberta Albuquerque

I'm currently a PhD student at the University of Warwick, Department of Statistics and I work under the supervision of Dr. Dario Spanò and Prof. Vassili Kolokoltsov.

My research interests are the following:

  • Stochastic Integrable systems
  • Random matrix theory
  • Macdonald processes
  • Macdonald polynomials

I'm also interested in Geometric Analysis and Stochastic Analysis.

Current Research

  • I am focusing on topics related to random matrices and stochastic integrable systems. The seminars and talks at Warwick are giving me ideas and I am writing notes about it.
  • I’m also interested in topics related to Geometric RSK correspondence and Whittaker functions.

Past Research

  • Coalescent processes

I wrote some notes about coalescent processes and also exchangeable random partitions in my 9 months report. They are mainly based on Pitman, Gnedin, and Möhle papers.

  • M.Sc. by Research thesis

I considered a left invariant stochastic differential equation defined on the 3-dimensional Heisenberg Lie group. This SDE is associated to a hypoelliptic operator. I proved the integration by parts formula for this special case and I also calculated a Bismut type formula which I extended to the general case of a n-dimensional Lie group.

I worked with the Malliavin covariance matrix which turned out to be a 3x3 matrix with entries described as sums of integrals of Brownian motions and squared Brownian motions. The appropriate rescaling on the time variable turned out to be important to conclude that the determinant is positive which allowed me to calculate the inverse matrix and then arrived in a Bismut type formula. I also applied the adjoint of the derivative of the Itô map to perform these calculations.

During the period of work on this project I was interested in investigating the infinite-dimensional case.

  • Large Deviations

I wrote some notes on large deviations for validation on the TCC course and I received grade A for it. It consists of a generalization (from a nontopological point of view) of the classical large deviation principle for Gaussian measures. It is based on the notes "Isoperimetry and Gaussian analysis" by Michel Ledoux (St Flour course 1994).

  • Fragmentation processes

I wrote some notes on fragmentation processes based on the book “Random Fragmentation and Coagulation Processes” by F. Bertoin. After my 9-months presentation I received a question about those processes and I decided to learn more about them in order to answer this question and other questions in the future.

About me

I'm from Recife, Pernambuco, Brazil. It is located in the northeast part of Brazil and it boasts a beautiful archipelago called Fernando de Noronha nearby. The temperature is around 25-30 celsius all year long and people are extremely kind.

I love reading novels and poetry.
