(1) Nutrigenomics in dairy cows: development of high-throughput systems to study nutrigenomics; fine-tuning the metabolism through nutrients; transcriptomic and epigenomic effects of long-chain fatty acids; and nutritional genomics during transition from pregnancy to lactation.

(2) Milk and human health: effects of milk on obesity and bone development/regeneration, especially considering  mesenchymal stem cells and micro RNA present in milk's exosomes; effect of milk miRNA on immune system 

(3) Welfare and management of dairy cows: significance and effects of inflammatory-like conditions during peripartum; development of an integrative welfare system for dairy farms; and relationship between management and animal welfare.

(4) Systems biology: further development of the Dynamic Impacts Approach for use with omics dataset from complex experimental design, such as time course and multiple treatments experiments.



ANS 439/539 - Dairy Production Systems (4 credits, taught every fall quarter; topics covered by the class include: basics anatomy and physiology of dairy cows with emphasis on the peripartum period, nutrition and ration balancing, milk synthesis and mastitis, raising calves and heifers, buildings and facilities, milking procedures, milk price in US, manure and grazing management, animal welfare, and milk and human health. Visit and professional reports of the OSU Dairy Center and [optional] two commercial dairy farms)

ANS 538 - Lactation Biology (3 credits, taught every Spring term. Topics covered by the class include: mammary evolution, mammary macro and micro anatomy and systemic lactation physiology, milk synthesis, mastitis, transcriptomic regulation, and milk composition and quality)

ANS 505 - Reading and Conference (1 credit, taught every term. I cover topics related to writing research papers and presenting scientific data)

ANS 401 - Research in Molecular Nutrition (1-16 credits, taught every term. Students must be involved in ongoing research in my lab [the amount is dictated by the number of credits selected], plus they need to participate to our lab meeting and I meet with students every two weeks for an open discussion about any scientific topic)

ANS 599 - Special Topics (1 credit, taught every term. The students need to read scientific papers - including reviews - about specific topics and discuss the paper in class)

Fun Fact

I grew up spending summers grazing cows in the Alp, milking cows by hand, and making Fontina cheese
