Prof. Huffman joined the 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.  The primary research focus of the group is bioaerosols (atmospheric particles of direct biological origin) including pollen, fungal spores, and bacteria.  Our work involves: (1) development and improvement of advanced analytical techniques to provide 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.   

**We are frequently recruiting graduate and undergraduate students.** 
-Graduate students
will be considered after entrance into the graduate program in the Department of Chemistry and Biochemistry. An undergraduate degree in chemistry is encouraged for application to the department, but not specifically required. If interested in learning more, please email Dr. Huffman. To learn more about the graduate program at the University of Denver (DU), please click here.  For more information about DU in general, follow the link to the university’s main page or  YouTube channel.

-Undergraduate students at DU will be selectively considered from all majors/disciplines of science and engineering and at all stages of study to join ongoing research projects. Motivated students as early as their first year at DU may begin working with our lab. Undergraduate students may work at any time as a lab volunteer and as an upper division student for research course credit and may apply for summer stipend support through the DU Undergraduate Research Center (URC).  Undergraduate students are generally selected with evidence of strong academic record (i.e. GPA) and high maturity and motivation.  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.
