Description:Abstract: \n\nEnvironmental systems\, such as the hydrosphere 
 and atmosphere\, are a complex balance of chemical and physical processes 
 that impact nearly every facet of life. In the atmosphere\, aerosol partic
 les – tiny particles of liquid and/or solid floating in the air -- have 
 a strong influence on air quality\, climate\, and human health. For exampl
 e\, the aerosol effect on climate is one of the largest sources of uncerta
 inty in climate models. Human respiratory aerosol can also transmit certai
 n diseases.  Understanding aerosol particles is a unique challenge becaus
 e they can exhibit chemical and physical properties that are not observed 
 in bulk solution. In the first part of this talk\, I will discuss efforts 
 to understand and characterize the unique properties of aerosol particles 
 using levitation-based techniques to understand aerosol phase state. With 
 this approach we have demonstrated unique supramolecular effects on the ph
 ase state of aqueous aerosol particles composed of organic and inorganic c
 ompounds. The environmental and public health implications for droplet-bas
 ed supramolecular chemistry will be discussed.\n\nIn the second part of th
 e talk\, we will turn discussion to the hydrosphere\, where anthropogenic 
 activities have contaminated global water sources with environmentally-per
 sistent chemical species. One such class of “forever chemicals” are pe
 r- and poly-fluoroalkyl substances (PFAS)\, which are highly resistant to 
 natural degradation processes. PFAS are used widely in a range of consumer
  and industrial products and their widespread use has led to a global dist
 ribution. Certain PFAS have been linked to a myriad of  environmental and
  human health problems\, so there is a need to remove these compounds from
  water supplies. Here\, I will discuss ongoing efforts to destroy\, seques
 ter\, and detect PFAS.\n\nAlong the way\, I will highlight other areas of 
 my ongoing research at Sandia National Labs\, including gas-surface intera
 ctions on metal surfaces\, machine-learning based climate models\, and the
  development of analytical chemistry capabilities.\n\n&nbsp\;\n\nSandia Na
 tional Laboratories is a multimission laboratory managed and operated by N
 ational Technology &amp\; Engineering Solutions of Sandia\, LLC\, a wholly
  owned subsidiary of Honeywell International Inc.\, for the U.S. Departmen
 t of Energy’s National Nuclear Security Administration under contract DE
