Short CV

Jia Chen graduated from Universität Karlsruhe in 2006 with a Dipl.-Ing. degree in Electrical Engineering and Information Technology. She obtained her doctoral degree (summa cum laude) from Technische Universität München in 2011. In collaboration with Siemens, she developed compact laser-spectroscopic gas sensors with a focus on surface-emitting lasers (VCSEL) and fiber based gas sensing.

From 2011 to 2015 she was a postdoctoral fellow in the Environmental Science and Engineering department at Harvard University. In Prof. S.C. Wofsy’s group she worked on a method to determine the greenhouse gas emissions in cities by measuring the column-averaged gas concentration in the atmosphere. During that time, she was Co-Investigator of the NSF project “MRI: Acquisition of Mesoscale Network of surface sensors and solar-tracking spectrometers”.

Since 2015 Jia Chen has been the head of the Environmental Sensing and Modeling group at Technische Universität München.

She is also an Associate at Harvard University and she is (co-)author of more than 100 publications and has filed 12 patents.

Research Interests

Jia Chen’s current research focuses on quantifying greenhouse gas emissions and understanding the metabolism of pollutants in urban environments. Besides the development of novel, compact optical sensors, she is also interested in establishing a multidimensional sensor network with differential column measurements. Using these measurements combined with models of atmospheric transport, she wants to demonstrate a new experimental strategy to determine greenhouse gas and pollutant emissions.

Her research spectrum covers:

  • Urban greenhouse gas and pollutant emissions
  • Sensor network development with differential column measurements
  • Fourier transform spectrometry
  • Solar-tracking instrumentation
  • Atmospheric modeling
  • VCSEL-based gas sensing
  • Tunable diode laser absorption spectroscopy
