Haley focuses on biochemical and biomedical problems involving control at the molecular level, particularly biological systems regulated by protein–nucleotide interactions where the bioenergetics involved are expressed through site-specific nucleotide binding of high affinity or through protein substrate phosphorylation.

His lab synthesizes novel nucleotide analogs that are photoactive or fluorescent, or both, which are then used to study protein–nucleotide interactions which regulate enzyme activity. These probes have proven useful in his research into the causes of Alzheimer's disease, amyotrophic lateral sclerosis

, which his lab is currently investigating.

His laboratory's approach to the study of the general phenomenon of protein–nucleotide interactions is to synthesize novel nucleotide analogs that are photoactive or fluorescent, or both. The analogs are then used to study various interactions which regulate enzyme activity. Analogs used may be modifications of the commonly known nucleotides such as Adenosine triphosphate

 reject these claims. Haley's position is that there is a link between people with dental amalgams containing a high level of mercury and the level of mercury in the blood and urine. Critics of the anti-amalgam view have pointed to a study suggesting the amount of mercury released by fillings during normal use is minuscule and does not represent a threat to health.

. Haley has also speculated that gold salts may be useful in the treatment of autism. This was based on the observation that one of the first autistics known lost his autism diagnosis when treated for rheumatoid arthritis by taking gold salts containing a thiol linkage. Gold and thiols are known to have high affinity for mercury.

In June 2008, an FDA toxicologist questioned "on what basis the product could be expected to be safe and could be considered a dietary ingredient", but CTI Science and Haley had not responded as of January 2010. The question was, however, in response to a 75 day premarket notification for a supplement which precluded testing on humans until after its submission.
