..............................................................
I am a 4th PhD candidate in the ACO
program (Algorithms, Combinatorics and Optimization) at the
Tepper School of Business, Carnegie Mellon University.
I am fortunate to be advised by R.Ravi and
Andrew Li.
My research lies on the interface between Operations Management, Operations Research, and Machine Learning.
On the theory side, recently I focus on the interplay between online learning and optimization, especially problems motivated by pricing, supply chain management and online platforms.
On the application side, I collaborate closely with industry to bridge the gap between theory and practice, and aim at maximizing the business impact of theoretical ideas.
Currently, I am leading a joint project with Glance, India's largest mobile lock-screen content provider with more than 100 million daily active users, to improve their recommender system by incorporating ideas from online learning.
I am also working with Bestar Bush, a leading North American furniture manufacturer, on modernizing their global supply chain, in particular, on improving the resilience and service level by leveraging their massive historical data.
I received my BS degree in
Mathematics from Tsinghua University in 2014,
and MS degree in Applied Mathematics and Statistics
from the State University of New York at Stony Brook in 2017, where I was lucky to work on geometric approximation algoriothms and computational gepmetry with
Joseph Mitchell.
Research Interests:
Dynamic pricing, revenue management, approximation algorithms, online learning, optimization under uncertainty
