Biography and Research Information

OverviewAI-generated summary

Paul C. Howard's research focuses on toxicological studies, particularly involving chemical exposures in animal models. He has conducted extensive studies on the toxicokinetics and genotoxicity of NNK (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone), a known carcinogen, in Sprague-Dawley rats. These investigations have examined various routes of exposure, including nose-only inhalation, intraperitoneal injection, and oral gavage, and have assessed both short-term (14-day) and longer-term (90-day) toxicity. His work also includes pharmacokinetic analyses of nicotine and its metabolites in rats, investigating their absorption, distribution, metabolism, and excretion following different administration methods.

In addition to direct toxicological assessments, Howard has contributed to discussions on broader research practices. He has published on the challenges posed by data silos in drug development, particularly for rare diseases, and has advocated for increased data sharing to accelerate research and development in this area. He has also contributed to the discourse on advancing alternative methods to reduce animal testing, reflecting a commitment to ethical considerations in scientific research. His scholarly contributions are evidenced by a significant publication record and a high citation count, designating him as a highly cited researcher.
