Biography

I am currently a Ph.D. student at UCL under the supervision of Prof. Iasonas Kokkinos. Before that, I was a member of the Computational Imaging Group (CIG) at Skoltech, where I collaborated with Prof. Stamatis Lefkimmiatis on learnable regularizers. My research interests include machine learning, 3D reconstruction, computational photography, and inverse imaging problems.

At the moment, I am working on the development of unsupervised 3D reconstruction from single frames and videos. All my research has been devoted on the development and incorporation of structured layers inside deep neural networks. As a structured layer, we can define an energy based formulation that incorporates human knowledge inside an agnostic machine learning solution. As an undergrad, I worked on the development of human emotion recognition from conversational speech data.

In addition to doing research, I love dancing (tango, salsa) and working out.
