Dr. Ruixue Lei

Postdoctoral fellow
rlei3 at jhu.edu

Research interests:
Ruixue is using observations from the OCO-2 satellite to estimate global carbon dioxide sources and sinks. He also wants to understand the environmental factors that drive the global carbon balance.

Leyang Feng

PhD student
lfeng13 at jhu.edu

Research interests:
Leyang is studying methane emissions from the United States. He previously worked in greenhouse gas research at the Pacific Northwest National Lab, and he is currently developing a first project for his PhD.

Mingyang Zhang

PhD student
mzhang78 at jhu.edu

Research interests:
Mingyang studies methane emitted from coal mines in China. She is exploring different ways that China could capture this methane and use it for eletricity production or home heating. She is interested in the potential benefits of these uses for air quality and public health.

Dylan Gaeta

PhD student
dgaeta at jhu.edu

Research interests:
Dylan is interested in urban greenhouse gas and air pollution emissions. He is also researching sulfuryl fluoride, a pesticide and greenhouse gas. Dylan began his PhD in Jan. 2020 and is originally from western New York.

Ziting Huang

PhD student
zhuang51 at jhu.edu

Research interests:
Ziting began her PhD at JHU in September 2021. She is interested in energy systems and greenhouse gas emissions from energy infrastructure. Prior to beginning her PhD, Ziting worked at the World Bank.

Mason Liu

PhD student
hanyumasonliu at gmail.com

Research interests:
Mason is interested in exploring NOAA observations of air pollutants, primarily from the oil and gas industries. He aims to understand more about the emissions of these pollutants and how those emissions have changed over times

Julia Alumbro

Undergraduate
jalumbr1 at jhu.edu

Research interests:
Julia is analyzing the results of Baltimore City’s climate survey as part of the City’s Climate Action Plan. She is currently preparing a report for the City on the results of the survey.

Ao Chen

PhD student
achen152 at jhu.edu

Research interests:
Ao is interested in inverse modeling to better understand methane emissions. Prior to beginning at JHU, Ao was a masters student in Prof. Peter Kitanidis’ group at Stanford University.

Qiulun Li

PhD Student
qli88 at jhu.edu

Research interests:
Qiulun’s PhD is co-advised by Scot and by Dr. Kirsten Koehler at JHU. Qiulun is using network of low cost air quality and greenhouse gas sensors in Baltimore to understand how to improve air quality across the city. Before coming to JHU, Qiulun completed a masters at the Emory School of Public Health.

Sharfan Upaul

Masters Student
supaul1 at jhu.edu

Research interests:
Sharfan is analyzing particulate matter observations from a network of low cost air quality sensors in Baltimore City. He is interested in understanding spatial disparities in air quality across Baltimore.

Lijin Zhang

PhD Student
lzhan177 at jhu.edu

Research interests:
Ljin is interested in understanding the environmental and human factors that drive nitrous oxide emissions. Nitrous oxide is the third-most important long-lived greenhouse gas.
