Research interests

I am interested in the analysis of nonlinear dispersive PDEs using tools from harmonic analysis, dynamical systems, probability, and operator theory. In particular, I address problems regarding the low-regularity analysis of (deterministic and stochastic) Schrödinger-type equations. My supervisor is Dr. Tadahiro Oh.

Notes

Teaching

In past semesters, I served as a tutor for:

Organized events

Attended meetings

Misc.

While an undergraduate student at the ``Politehnica" University of Timisoara (Romania), I took some interest in developing optimized code for training artificial neural networks. I have worked under the supervision of Dr. Dan Ciresan. Nowadays, I am curious to hear about new developments in machine learning, pattern recognition, or more broadly in artificial intelligence.
