Areas of Interest

Genetic regulation of the immune system and implications to disease resistance. Particular emphasis is given to preventive methods to improve disease resistance of livestock, such as genetic selection of livestock for enhanced immune responsiveness. Other areas of interest include xenotransplantation and peripartum immune responses.


Undergrad: MICRO*3230 (Immunology I), MICRO*4230 (Immunology II)
Graduate: PABA*6190 (Topics in Immunology)
