Academic Interests

• Teaching
  • Instructor in:
    - Graduate course ANSC*6390 - QTL and Markers (W)
    
    This graduate course is intended to teach statistical models and methods used in the detection of Quantitative Trait Loci (QTL) and in marker assisted/genomic selection of livestock.
  - Graduate course ANSC*6050 - Biometry for Animal Sciences (F)
  
  This graduate course is intended for students involved in animal research. The course will provide outlines of appropriate presentation and analysis of experimental data with emphasis on different analytical techniques.
  
  •  Past instructor in:
  - Undergraduate course UNIV*1200 - First Year Seminar Course (F)
  The goal of this course is to provide opportunities for students to participate in small, discussion-oriented classes in their first year in a topic of general interest. The goal of the Fall 2008 session was to discuss social, economic, political, and ecological issues on Brazilian Amazon deforestation and how it can affect and be linked to people living in Canada.
