Dr. Tadele is an environmental engineer who is interested in studying the impact of diffuse pollution on receiving waters, functionality and maintenance of stormwater treatment practices, and green urban infrastructures as stormwater management practice and other ecosystem services.

His expertise includes the development of laboratory and field test methods to assess the suitability of filter media. Dr. Tadele was a lead investigator and author of the Austrian Standard "Soakaways for runoff from roof gutters and reinforced surfaces - Part 3: Filter materials - requirements and tests methods” for the certification of filter media. Recent studies focus on investigating biochar and Minnesota sourced filter media for the removal of pollutants commonly found in stormwater and agricultural runoff as well as sizing and designing of biofiltration system.
