Research and Teaching Interests
Professor Chen studies optimization models and algorithms, particularly the optimization under uncertainty (integrated risk and decision modelling, sparse grid scenario generation) , interior point method (barrier functions, warm start strategies, complexity analysis) and large scale optimization of the deep learning neural network (recurrent neural network, Monte Carlo Tree search, tensor analysis).
- Deep Learning
- Operations Research
Professor Chen teaches graduate courses on stochastic programming and nonlinear optimization, as well as undergraduate courses on linear optimization, combinatorial optimization, operations research models, linear algebra and advanced calculus.
