Research

I study large, often high dimensional objects in the presence (or with the help of) randomness. These "objects" sometimes come from the math world - such as, random matrices or tensors, or being motivated by applications - such as, linear systems or large collections of complex data.

My favourite applications include dimensionality reduction, randomized algorithms for solving linear systems, corruption detection and dynamic topic modeling.

Research Statement

You can find full list of my publications and preprints, explore slides of my talks, or check out some upcoming travel plans talks information below:

  • Applied Mathematics & Statistics seminar at Johns Hopkins, February 11, 2021
  • SIAM Conference on Computational Science and Engineering, March 1-5, 2021

I will also be participating in IPAM Long Program in Tensor Methods and Emerging Applications to the Physical and Data Sciences (March-June 2021)


Teaching

In Fall 2020, I am teaching Math 164 (Optimization) remotly. I am using CCLE webpages to post all the information and assignments. If you are my student, make sure to subscribe your emial for CCLE announcements!

At UCLA: I taught Math 170A (Probability, Fall 2018) and 170S (Statistics, Winter and Spring 2019). I also taught Math 170A (Probability) and Math 171 (Stochastic Processes) in Spring 2020 remotely.

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

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, I enjoy coding and playing with data. Back in Moscow, I completed two year CS program in Yandex Data Analysis school, and it was such a great time. Nowadays I infrequently participate in online contests alone or with friends.

My other interests include all that I find beautiful or challenging. For example, songs, art, cities, mountains, cats, puzzles... Finally, I love talking to people, sharing experiences and drinking coffee - dark roast preferrable.

“Poirot,” I said. “I have been thinking.”
“An admirable exercise my friend. Continue it.”
