Born on 1962 in Brunswick, Maine.
My research interests envelope two aspects of the mesosphere and lower thermosphere. Both involve the use of the resonance lidar techniques developed at the Arecibo Observatory together with the global middle-atmosphere lidar community. First, I am carrying out measurements of temperatures in the metal layer (83-103 km) in order to enhance our understanding of the diurnal and seasonal structure and dynamics of this transition region between the neutral atmosphere and ionosphere. Second, I am working with experts on meteors to make optical measurements of meteoric input into the atmosphere. This is divided into two areas: 1. direct detection of meteor trails; and 2. the topside extent of the metal layer above 110 km (sometimes extending to 150 km), which seems to have a direct relationship to meteoric input.
