Cohn served in the office of Senator Bill Bradley(Doctorate-New Jersey) in 1995-1997 as a American Association for the Advancement of Science Congressional Science Fellow, and worked on the unsuccessful Bradley presidential campaign in 2000. Cohn"s research has focused on flood frequency analysis, estimation of nutrient transport in rivers, and the interpretation of trends in hydroclimatological data. Cohn"s most controversial research, which has not been fully embraced by the climate science community, suggests that the significance of climate trends may be greatly overstated because it does not consider the possibility that long-term persistence is a component of climatic variability.
Cohn holds a Bachelor of Arts in mathematics from Swarthmore College (1979) and Master of Arts (1984) and Doctor of Philosophy (1986) degrees in water resource systems engineering from Cornell University.
Cohn is an avid marathoner and past president of the Reston Runners organization in Reston, Virginia.
Since 2005, Cohn has been a member of the Governing Board of the American Institute of Physics. Cohn is a current board member of the Reston Association.
