I am an Assistant Professor in Columbia University Earth and Environmental Engineering, with affiliation in Electrical Engineering, and a core faculty in Columbia Electrochemical Energy Center. My research interests are in sustainable energy and power systems, electricity markets, and energy storage.
I obtained my PhD in Electrical Engineering from University of Washington, Seattle, advised by Daniel Kirschen and Baosen Zhang. I did my Postdoc in MIT, hosted by Francis O’Sullivan and Audun Botterud. My CV is here.
My research proposes algorithms and market designs towards an economic, reliable, and sustainable power system. I’m particularly interested in the following topics.
Energy storage offsets renewable fluctuations and is the key to a low-carbon future, but managing these assets at the system level remains an open question. Operators must make real-time dispatch decisions to mitigate instantaneous imbalances, but also need to consider the value of stored energy in the future. Shaping future insights into a computation-viable form is a challenge that requires efficient operation algorithms and advanced data analytic tools.
A power system is more than a physical infrastructure, it interconnects millions of individuals with different roles and objectives. A household with roof-top PV is both a consumer and a producer, but might not be an active market participant. Merchants like energy storage and financial entities are neither consumer nor producer, but they contribute flexibilities and liquidities that aid power system operations. Analyzing individual objectives and looping their behavior into the system design is of great importance.
With more inertia-free and distributed resources, the power system is transforming from a centralized sequential-stage scheme into a hierarchical structure with autonomous local agents and aggregations. This transformation poses a series of interesting research questions such as designing new market flexibility products and interfacing local aggregations with the wholesale market.
I traveled many places during my career and am fortunate to have worked with many great researchers. I have arranged my experience based on the cities I lived.
I obtained my BS degree in ECE from SJTU in August 2011.
I started my master on power systems and power electronics in ETH Zurich in September 2011 and received my master degree in Electrical Engineering in February 2014.
I spent my 2014 summer in Beijing as a research intern in China Electric Power Research Institute where I worked on wave power generation. .
I interned at Doosan Gridtech during the summer of 2017 where I worked on several industry projects on battery energy storage and market analysis.
I will join Columbia University as an Assistant Professor in January 2020.
