Research Statement
Dr. French’s research focuses on gaining a better understanding of microphysical processes
that occur in clouds leading to the production of precipitation. Dr. French uses in
situ observations from aircraft to characterize thermodynamic, dynamic, and microphysical
properties of clouds. These observations provide the basis for describing which processes
may be important under a given set of conditions. Critical to this line of research
is the ability to make accurate and well-characterized measurements from aircraft
in clouds. To that end, an emphasis is placed on instrument calibration and characterization.
