Reviewer of Mathematical Reviews (American Mathematical Society) from August 2012

Research projects Our research areas are around Applied Probability, Stochastic Process, Queueing Theory and their applications in Stochastic Systems. We have been developing models for call centers, data centers and telecommunication systems. We are also interested in developing new mathematical tools for analyzing stochastic models arising from real world systems.

Methodologies: Applied Probability, Mathematical Engineering, Stochastic Models, Queueing Theory, Mathematical Models

Applications: Service Management, Modelling and Performance Evaluation of Service, Social, Information Systems
Guidelines for advisees I would like to support students who have big dream. I welcome students with strong background in mathematics who want to use mathematical tools to solve real world problems. My research focuses on performance evaluation of stochastic resource sharing systems such as queueing systems, service systems, telecommunication systems and on developing mathematical tools for analyzing these systems. If you are interested in these topics, please do not hesitate to contact me.

We are closely collaborating with leading researchers from various countries over the globe. We encourage students to present their research results in international conferences and journals.

We warmly welcome active and highly motivated international students!!
