Kifle Gebremedhin is a Professor in the Department of Biological and Environmental Engineering. He is an elected Fellow of the American Society of Agricultural and Biological Engineers (ASABE) and a member of ASCE, National Frame Builders Association, Institute of Biological Engineering, and various honor societies. He is the recipient of numerous awards for teaching, research, advising, service and leadership. Professor Gebremedhin has published over 180-refereed journal articles and research technical publications and has made several invited presentations nationally and internationally.

Research Focus

Professor Gebremedhin’s research program involves: Animal thermal stress physiology, modeling animal bio-energetics (heat and mass transfer), engineering livestock thermal environments, diaphragm design of post-frame buildings, and structural connections.

Teaching Focus

Professor Gebremedhin teaches a fundamental course (BEE 3310 Bio-Fluid mechanics) and an engineering design-based course (BEE/CEE 4810 LRFD-based Engineering of Wood Structures).

Bio-Fluid Mechanics (BEE 3310). This course is a required course for biological engineering majors. It is taken primarily by junior and some senior students. The course is offered during the Fall semester and during the 6-week summer program for students who plan to go for Engineering Coop in the fall. The course emphasizes fundamental concepts through biologically-inspired case studies.

LRFD-Based Engineering of Wood Structures (BEE/CEE 4810). This course serves as an engineering elective to our majors and it also satisfies the capstone engineering design requirement of the major. This course is co-listed as a CEE course as well, and is taken by CEE seniors and M.Eng. students. The course is offered during the Spring semester. The course emphasizes engineering design of structural components and systems using wood and wood products as a structural material.

Special Topics in Civil Engineering (CEE 3090).
Students in this course were involved in research, design, construction and fund raising to build a pre-school in Cosmos City, Johannesburg, South Africa. The actual construction was accomplished during the summer of 2011.
