College of Agriculture & Natural Resources Department of Animal Science

I am an Animal Scientist with a background in lipid metabolism and meta-analyses. My Ph.D. was focused on understanding the effects of calcium salts of palm fatty acids on nutrient digestibility, energy partitioning, and production responses of lactating dairy cows. In addition, I have experience running and managing dairy cow experiments, data handling, complex statistical analysis, manuscript preparation, and scientific research presentations. An essential part of my training was obtained at Michigan State University under the supervision of Dr. Adam Lock, where we performed a series of meta-analyses to evaluate the effects of commercially available fatty acid supplements and the role of individual fatty acids on nutrient digestibility, post-absorptive metabolism, and production responses of lactating dairy cows.
