In recent papers he was focusing on the following fields of study:

Dry matter, Agronomy, Forage, Endocrinology and Internal medicine are his primary areas of study. His Dry matter research integrates issues from Silage, Alfalfa hay and Yield. His Silage study results in a more complete grasp of Food science.

The various areas that he examines in his Forage study include Cultivar and Crop. His study in Endocrinology is interdisciplinary in nature, drawing from both Lactation and Animal science. His work on Enterocyte as part of general Internal medicine research is frequently linked to Mastitis, bridging the gap between disciplines.

Between 1982 and 1991, his most popular works were:

  • Added Ammonia or Microbial Inocula for Fermentation and Nitrogenous Compounds of Alfalfa Ensiled at Various Percents of Dry Matter (131 citations)
