Profile

I am a second-year Ph.D. student in the combinatorics group.

Research

Research Interests:

My research interests include the development and analysis of approximation algorithms for combinatorial optimization problems under specific settings. In particular, I enjoy working on both online and offline settings while exploring the limits of approximability.

I am especially interested in the optimization of submodular functions and their connection to real-world applications. Submodular functions are extensively used in machine learning and artificial intelligence. However, the growth of datasets requires new algorithms working without access to the entire data at all times. On the other hand, in practice, greedy algorithms have found extensive use to optimize submodular-like functions, but theory lags behind.
