Gad is known for his work on experimental physiology. He has conducted numerous studies on electrophysiology, spinal cord functionality, and the relationship between lactic acid in muscle contraction and others. Among his written work was a textbook on human physiology, which he brought out together with the pharmacist Jean-François Heymans : "Short textbook of human physiology", and a treatise on skin stimuli, which he wrote together with Alfred Goldscheider (1858–1935 ) published. The textbook was reprinted in 2007.
