Biography

My interests lie in two distinct areas of space science: a) the interaction of the Earth's atmosphere with surfaces of materials on satellites moving at high relative velocity, and b) measurement of the high energy radiation environment outside the atmosphere. Each of these programs involves the design and building of instruments to fly on satellites and high-altitude balloons (7 shuttle flights and 15 balloon flights, to date).
