Biographical Info

Dr. Kipen received his BA from UC Berkeley and his MD from UC San Francisco and MPH from Columbia University.  He completed an internal medicine residency at the Columbia-Presbyterian Medical Center, and a fellowship at Mount Sinai Medical  Center, Environmental Sciences Laboratory, in Manhattan.

Research Areas

Dr. Kipen’s research focuses on clinical and epidemiological studies of the health effects of ambient and indoor air pollution. He works closely with Rob Laumbach of the CROM division as well as Debra Laskin and Andrew Gow of Toxicology. They use both controlled human  exposure models and real-world clinical studies to develop and test mechanistic biomarkers of air pollution toxicity. Concentrating on biomarkers of cardiopulmonary effects, prior studies have examined fresh diesel exhaust and secondary organic aerosols. We are currently studying effects of controlled ozone exposures on macrophage phenotypes in induced sputum.   Working in the real world, we have examined cardiopulmonary and oxidative stress outcomes in highway passengers who were driven in a diesel-enriched enriched environment. More recently we examined the ability of portable air cleaners to reduce indoor particulate air pollution and consequent biomarkers of cardiopulmonary health in elderly apartment dwellers.   In light of the current pandemic we have used our experience measuring and filtering particulates in homes to examine SARS-coV-2  aerosols in patient homes.  A more recent interest is to explore underlying mechanisms for the robust human finding of acute cognitive impairment from inhaled CO2 at commonly encountered levels.

Research Highlights

With former EOHSI members Jim Zhang and David Rich, we conducted a panel study of 130 Beijing medical students built around the Chinese Government’s drastic reductions in air pollution during the 2008 Olympics. We observed broad declines in multiple oxidative stress, inflammatory, and platelet activation biomarkers. Major results have been published in JAMA and the American Journal of Respiratory and Critical Care Medicine with multiple subsidiary papers and a complete report published by the Health Effects Institute. We have Analogous increases in vascular and pulmonary oxidative stress  have ben demonstrated after a 90 minute ride on the NJ Turnpike. Similar findings have been found using controlled exposure to fresh diesel exhaust iin our controlled environment  facility. Related effects have been shown with New Jersey air pollution on the Turnpike and are being evaluated with air cleaners in individual homes.

Significant declines in proteasome (UPP) activity after exposure to secondary organic aerosol and diesel exhaust were observed immediately following exposure in healthy subjects, although our prior work did not reveal apparent nasal inflammatory effects from acute exposures to secondary organic aerosol. The above declines in proteasome activity showed a significant interaction (3-fold increase) in subjects with the ILE/ILE polymorphism of GSTP1.
