Angela R. Green, Ph.D., E.I.T.

Angela R. Green, Ph.D., E.I.T. is currently an assistant professor in the Department of Agricultural and Biological Engineering at the University of Illinois at Urbana-Champaign. Her achievements in biological and agricultural engineering include systems and facilities designs, innovative research into quantifying animal behavior, and advising students as part of research experiences for pre-professionals and graduate students. Animal behavior research is necessary to understand animals’ needs so that housing systems and management can be better designed. Dr. Green’s research on animal preference, which laying hens were able to “vote” for their favorite environments by moving between chambers, illustrates some of her significant contributions in both research and design.

Dr. Green’s design experiences include a unique biofilter for treating headspace gases in impermeable above ground swine slurry tanks, and designed a flexible painting booth for removing paint particulates during machinery and components painting.
