University of Denver (DU) in Dec. 2011 and is currently an assistant professor in the Department of Chemistry and Biochemistry within the Division of Natural Sciences and Mathematics (NSM).
The research of the Huffman lab focuses on analytical and atmospheric chemistry, emphasizing the development and application of new scientific approaches to addressing environmental problems. Most of this work involves atmospheric aerosols (small particles suspended in the air) from both field and lab perspectives. Atmospheric aerosols can either be natural or anthropogenic (human-caused) in source and can: severely reduce sky visibility, influence the Earth's radiative balance (climate forcing) directly or through affecting cloud formation, damage ecosystems via deposition of toxic chemical species, and affect human health through respiratory, cardiovascular, and allergenic diseases. Our work involves: (1) development and improvement of advanced analytical techniques providing better tools for the study of atmospheric aerosols, (2) characterization of particles generated in the laboratory in order to better understand physical and chemical properties that influence atmospheric effects and human health, and (3) collection and analysis of field samples from all over the globe to directly measure particles from the natural environment.
**Now selectively recruiting graduate and undergraduate students.**
-Graduate and undergraduate students will be selectively considered from all applicable disciplines and academic backgrounds for research projects appropriate to experience level. Undergraduate students may work for course research credit, for work-study money, or as lab volunteers. Undergraduate students are generally selected with evidence of strong academic record (i.e. GPA) and high maturity. If interested in learning more, please email Dr. Huffman with interest.
-Postdoctoral scholars who are at least partially funded are also being recruited.
-If interested in joining the group please send Prof. Huffman a copy of your CV along with questions or interest. Click here for formal student application for study at DU.
