CV (March, 2021)


I study the structure of large high-dimensional objects in the presence of randomness, and use this understanding to develop randomized algorithms that efficiently process complex data. The objects of my study range from matrices, graphs and tensors to any instances of large data.

My current favourite directions include low-rank tensor factorization and dimension reduction, randomized methods for solving linear systems and more general optimization tasks, corruption detection and dynamic topic modeling.

See here for the list of my most relevant papers and preprints roughly organized by topic; see my CV (a button above) for the full list of publications; and see here for some past talks slides. Also,

Research Statement (2020)

I will be teaching ORF387 (Networks) class in Fall 2022.

Past teaching

At Princeton: ORF523 (Convex and Conic Optimization, Spring 2022)

At UCLA: Math 170A (Probability, Fall 2018 and Spring 2020 - restructured for math majors), 170S (Statistics, Winter and Spring 2019), Math 171 (Stochastic Processes, Spring 2020) and Math 164 (Optimization, Fall 2020).

At UofMichigan: Math 115 (Calculus 1; primary instructor); Math 216 (Differential Equations; Matlab labs and problem solving recitations) and Math 623 (Computational Finance; TA).

Back in Moscow, I worked as a calculus instructor for high school students at 57-th math school (2008-2012) and as an algebra teacher at Kolmogorov math and physics high school (2012-2013).

Random likes

My first name is the Russian version of Elizabeth. I like all versions of my name: please call me Liza, Lisa, Eliza, or Elizabeth, whatever you like the best. In case you were curious, Elizaveta is pronounced as "Ye (like in yellow) - lee - zah - VYE - tah". Standard pronunciation of Liza is "LEE - zuh".

In addition to doing research and explaining math for various audiences, I enjoy coding and playing with data. During my undergraduate time in Moscow, I completed two year CS program in Yandex Data Analysis school, it was such a great time.

My non-mathy interests include all that I find beautiful or challenging. For example, songs, art, street art, cities, oceans and mountains, cats, great stories of any kind, poetry and classic fantasy, puzzles... Finally, I love consuming and talking about coffee and European sweets.
