Dr. Lars Kalnajs

University of Colorado – Laboratory for Atmospheric and Space Physics

Dr. Lars Kalnajs is an atmospheric scientist at University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder, Colorado.   He has spent the last decade doing science in Antarctica; working on experiments ranging from operating a network of autonomous ground based chemical sensors, to launching a fleet of balloon to study the Antarctic Stratospheric Ozone Hole.   During the other half of the year, Lars designs and flies atmospheric chemistry and physics instruments on balloons and airplanes in the warmer parts of the world.  He particularly enjoys the challenge of making new and creative measurements in harsh and remote environments.   Lars is the Principal Investigator for 2ODIAC.

Professor Peter DeCarlo

 Drexel University

Dr. Peter DeCarlo is an Assistant Professor in the Department of Civil, Architectural, and Environmental Engineering and Department of Chemistry at Drexel University. His research is focused on the measurement of particles and gases in the atmosphere, typically focused on the use of aerosol mass spectrometers.  He has made measurements in cities, remote mountaintops, airplanes, and mobile trucks to study issues of air quality, atmospheric chemistry, climate impacts, and identification of pollution sources. This is his first trip to Antarctica, and he is looking forward to using aerosol mass spectrometry to study the aerosol particle composition in such a pristine environment.  Dr. DeCarlo is co-Principle Investigator of the 2ODIAC project. (He is also a new father)

Dr. Michael Giordano

Drexel University

Mike recently received his PhD in Chemical and Environmental Engineering from the University of California, Riverside and is now working as a post-doctoral research associate at Drexel University. Mike has been involved in a wide spectrum of atmospheric aerosol research since first entering the field as an undergraduate at Columbia University. His interests include aerosol composition, hygroscopicity (cloud forming potential), and morphology and their effects on the Earth’s global radiative balance. Doing research in Antarctica has been a dream of his since entering the aerosols field and he is extremely excited to participate in 2ODIAC. Be sure to tune in for updates and blog posts about researching and living in Antarctica from a newbie’s perspective!

Professor Terry Deshler

University of Wyoming / University of Colorado 

Terry Deshler, a Professor Emeritus from the University of Wyoming, has directed research on the impact of atmospheric aerosol (particles) on chemical, radiative, and hydrologic atmospheric processes for the past 25 years. This work has led to balloon-borne measurements of stratospheric aerosol and ozone in the mid latitudes, polar regions, and tropics of both hemispheres. His interests include Antarctica ozone loss, polar stratospheric clouds in both hemispheres, mid latitude stratospheric aerosol, including the effects of major volcanic eruptions, and aerosol instrumentation. Terry is an author or co-author on over 120 scientific papers published in these areas, has contributed to several of the UNEP/WMO ozone assessment reports and the SPARC Assessment of Stratospheric Aerosol Particles. Balloon-borne measurements of aerosol from Laramie have been completed since 1971, and continue to today under his direction.

Dr. Sean Davis

National Ocean and Atmospheric Administration / University of Colorado

Dr. Sean Davis is an atmospheric scientist at the NOAA Earth System Research Laboratory in Boulder, Colorado. He studies the causes and consequences of changes in the concentration of trace gasses such as water vapor and ozone high in the stratosphere, with a particular focus on how these changes impact climate at the surface of the Earth. Dr. Davis’ previous research includes studies of cirrus cloud properties from aircraft, and surface chemistry measurements from the surface in Antarctica (2004).

Anita Johnson

Drexel University

Anita Johnson is a PhD candidate in Environmental Engineering at Drexel University.  This is her first trip to Antarctica.  Her primary research focuses on the relationship between outdoor pollutants and indoor air quality.  She has utilized the SP-AMS or the mini-AMS for most of her work, and she looks forward to new ways to use these instruments to better our understanding of atmospheric processes.
