Christos Stamatis CV
Postdoctoral researcher
e-mail: christoss (

Research Interests: Wet deposition of gasses and particles, biomass burning emissions, mass spectrometry and data analytics. I am particularly interested in developing parametrizations for wet scavenging of gasses and particles in order to enhance our understanding of those processes.      

Engineering Interests: Writing software that automates instrument monitoring (crash logging, user notifications) and streamlines the data handling process after logging (pushing to cloud storage, raw data handling)

General interests: When I am not working I really enjoy cooking, playing with my guitars and improving my homelab (NAS + mini-cluster)


James Hurley
Postdoctoral researcher
e-mail: jamesfh (

Research Interests: Instrument development, characterization of emissions from biota and fragrance mixtures. More generally, I am interested in organic and physical chemistry, spectroscopy and kinetics. Recreation-wise, I enjoy reading, archery, hiking/climbing in the mountains and trying to learn Mandarin.

Sungwoo Kim
Ph.D. student
e-mail: sungwookim (

Research Interests: Analysis and interpretation of large and complex data. I’m particularly interested in the development of an efficient automated algorithm for the analysis of data produced by Gas Chromatography/Mass Spectroscopy systems. This aims at potentially increasing the accuracy and speed of data processing for a larger computing capability. My background is in air quality modeling and analysis, and I am excited to apply my previous skills as well as learn new ones in the field of GC. In my free time, I enjoy travelling, reading, golf, and playing basketball.

Purushottam Kumar
Ph.D. student
e-mail: purushottamk (

Research Interests: Developing novel techniques and instruments for studying Atmospheric chemistry (both gas and particle phases) and doing the source apportionment analysis of atmospheric aerosols. I would like to study the atmosphere of other celestial bodies (e.g. Mars) sometime in future too. I am also interested in studying archaeology especially past climate and evolution of different species over time and the science & technology of the ancient civilizations. In my free time, I like to sit alone listening to old Hindi songs or go hiking .

Namrata Panji CV
Ph.D. student
e-mail: namratapanji (

I am interested in indoor and outdoor atmospheric chemistry, especially emission and the fate of semi-volatile organic compounds (SVOCs). I am currently working on studying SVOCs in the environment and dabbling in instrumentation and measurement techniques. I also enjoy water and wastewater treatment designing. In my free time, I like to catch up on reading and cooking new cuisines..
