Ph.D. @Cornell, Forbes 30U30

G. Scholar







I am a Ph.D. candidate in the Erickson Lab at the Sibley School of Mechanical and Aerospace Engineering at Cornell in Ithaca, NY. My major is Micro & Nanoscale Engineering, with minors in Energy & Sustainability, Infection & Immunity, and Entrepreneurship. My research at Cornell has two lines: (1) HI-Light (thesis), a glass waveguide based photoreactor technology for converting CO2 to fuels; (2) FeverPhone, a smartphone based molecular diagnostics platform for differential diagnosis of six acute febrile illness.

Below are the snapshots for my background.

Three 30 Under 30 lists: I was honored to be selected as one of the “30 Under 30” in Energy by Forbes Magazine (2018), was among “EarthX 30 Under 30: The Green Generation” by the American Conservation Coalition (2019), and the “AACYF Top 30 Under 30 Elites” in “Art, Culture, Science” by All America Chinese Youth Federation (2019).

Public speaking: I was selected as an INK Fellow by the Ixoraa Knowledge Foundation to give speak about solar fuels in Jaisalmer, India (2019), was an invited speaker at IoT, Data, and the New Last Mile by TTI/Vanguard in Berkeley, CA (2019), and was selected to present at Global Grad Show, an exhibition of creativity and social innovation of the Dubai Design Week (2019).

Social impact: I was named as a Local Pathways Fellow by the UN SDSN–Youth (2018-2019), a Global Shaper by the World Economic Forum (2019), and a BP Advancing Energy Scholar to attend the One Young World Summit in London (2019). I was one of the five regional finalists for North America in the Young Champions of the Earth Competition by UN Environment (2019), and one of the six national finalists in Lemelson-MIT Student Prize by the Lemelson Foundation (2019). I received Honorable Mention for the Link Foundation Energy Fellowship by the Link Foundation (2019).

Entrepreneurship: I am pursuing an entreprenership minor at Cornell, and am the current co-president of the

For the HI-Light project, I was participating in a team that won the $20K Grand Prize (1/1,150+ in the world) in the “Create the Future” Design Contest (2017). The industrial partner in the HI-Light effort, Dimensional Energy, has advanced into the final round (10 teams in the world) for the $20M NRG COSIA Carbon XPRIZE (2019).

Prior degrees: M.S. in Mechanical Engineering from Cornell (2019), M.Eng. (thesis) in Materials Engineering from McGill (2016) with joint training by the Nuclear Engineering Department at the Massachusetts Institute of Technology (2015-2016), a dual bachelor’s degree (B.Eng. in Energy & Power Engineering; B.A. in English Language & Literature) from the ‘Tsien Hsue-Shen’ Elite Class of Xi’an Jiaotong University (2013).

Acamedic activities: I have recently published work in Int. J. Hydrog. Energy, Anal. Chem., Fuel, Fuel Process. Technol., ISIJ Int., Malaria Journal, and Metall Mater Trans B, and am a reviewer for several journals including J. Clean. Prod., Energy Convers. Manag, Int. J. Hydrog. Energy, IJEE, Metall Mater Trans B, etc.
