(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.

I accept graduate students for Animal and Rangeland Sciences Department
Courses Taught: 

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)

OSU Main Campus

I grew up in Bionaz, a small village in the heart of the Alps. Since the age of five-years-old, during the summer, I would help my father to graze cows in the mountains and produce Fontina cheese. When I was 14-years-old my family started a touristic business (with a mountain resort and hotel) and, due to my passion for dairy animals, my father gave me the responsibility to run the dairy farm in the summer months. I did that job until I was 19-years-old, at which time I became a student in agriculture at Universita Cattolica del Sacro Cuore, Piacenza, Italy.

In October 2000 I graduated (110/110) with a thesis titled "Chemical-nutritional characteristics of Valle d'Aosta forages and diets optimization for lactating dairy cows" conducted in the Instituto di Zootecnia under the supervision of Professor Giuseppe Bertoni (now retired) and Professor Luigi Calamari. In April 2001 I started my PhD in the same Instituto di Zootecnia under supervision of Professor's Bertoni and Calamari plus Professor Erminio Trevisi where I worked on transition dairy cows and a system for animal welfare evaluation on dairy farms.

In 2002 I had the opportunity to spend six months in the laboratory of Professor James Drackley in the department of Animal Sciences at University of Illinois at Urbana-Champaign as a visiting scholar. I defended my PhD in April 2004 with the thesis titled "Studies on relationships between hepatic functionality and inflammatory phenomena around parturition. Results on productive and reproductive performances." In December 2004 I had the opportunity to move to Pennsylvania (US) 1 year as a post-doctoral scholar with Professor Gabrielle Varga (now retired) in the department of Animal Science at Penn State University. There I started to work on Nutrigenomics. In January 2006 I moved to the Mammalian nutriphysiogenomics laboratory of Professor Juan J. Loor where I continued to work on nutrigenomics, but I had also worked on physiogenomics and systems biology. In May 2009 I moved into the laboratory of stem cell biology and bioengineering of Professor Matthew Wheeler where I worked on mesenchymal stem cells for adipogenesis and bone regeneration.

In November 2012 I moved to Oregon State University where I started my position as Assistant Professor in dairy nutrigenomics and management.
