GESTAR II Seminar Series, November 9 at 11:00am

Join us for a virtual seminar by Dr. Meredith Hastings, Professor, Physical Sciences, Brown University. Her talk is titled "Fingerprinting Reactive Nitrogen Sources and Oxidation Chemistry".

Date and Time: Thursday, November 9, 2023 at 11:00am

Join us via Teams.

Abstract: 

"Reactive nitrogen species (including nitrogen oxides, ammonia, nitrate, nitrite, ammonium, and organic nitrates) serve major roles in controlling the composition of our atmosphere, and have a direct impact on ecosystem health and water quality. Hastings' research group is focused on using the nitrogen and oxygen stable isotopic composition of reactive nitrogen species to investigate variations in sources, oxidation chemistry, atmospheric transport, and deposition. This seminar will discuss recent method developments to capture gaseous nitrogen oxides in situ for determination of isotopic composition; approaches to laboratory versus field experiments for documenting isotopic signatures associated with emission sources; and applications of these techniques from wildfires to agricultural to urban-based emissions."

Biography:

Meredith Hastings is the George Ide Chace Professor of Physical Sciences at Brown University. She has a joint appointment in the Department of Earth, Environmental, and Planetary Sciences and the Institute at Brown for Environment and Society, an interdisciplinary research center focused on understanding interactions between natural, human and social systems. Prior to joining the faculty at Brown in 2008, Meredith was a postdoctoral fellow at the University of Washington's Joint Institute for Study of the Atmosphere and Ocean (JISAO). She completed her Ph.D. at Princeton University, working with researchers in the Department of Geosciences and at the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory. She is an NSF CAREER awardee, a recipient of the American Geophysical Union's Atmospheric Sciences Ascent Award and was named one of Insight into Diversity's 100 Most Inspiring Women in STEM. She is currently a co-PI of ADVANCEGeo (serc.carleton.edu/advancegeo), a national program funded by NSF to transform workplace climate in the geosciences and other scientific fields through the development of bystander intervention and research ethics training in partnership with professional societies. She also serves as President of the non-profit Earth Science Women's Network (ESWN, www.eswnonline.org), whose mission is to connect women in the Earth sciences to develop their careers, build community, provide informal mentoring and support, and facilitate professional collaborations. She is also a proud mom of two beautiful, middle-school aged daughters.
