Education and research

Jarzynski graduated from Our Lady of Good Counsel High School in Wheaton, Maryland in 1983. He then attended Princeton University from where he graduated with high honors with an A.B. in physics in 1987 after completing a senior thesis titled "An experimental search for 1.7 MEV

His research is primarily in the area of non-equilibrium statistical mechanics, where he has contributed to an understanding of how the laws of thermodynamics apply to nanoscale systems. In 1997, he derived an equality, now known as the
