Research interests:

My scientific interests include the study of the Earth as a system with emphasis on global climate change, solar variability and the Sun-Earth connection, and the interaction of cosmic rays with Earth’s atmosphere and magnetic field.

I have been involved with the design and development of microcomputer-based research instrumentation for the past thirty years.  Recently, I was the lead inventor of an inexpensive, submersible, automatic water sampler (U.S. Patent No. 6,840,121).  My engineering interests include sensor networks and low-power device technologies.  I have also developed communication networks for remote seismic stations and other remote data acquisition applications.

Departmental activities:

Engineering support, including design, development, and maintenance of the following mass spectrometers and sample introduction systems:

Inductive-coupled plasma mass spectrometers
Thermal Ionization mass spectrometer (TIMS).
Stable Isotope mass spectrometer
Noble Gas mass spectrometer
 
Engineering support for paleomagnetics and environmental magnetics, including design, development and maintenance of the cryogenic magnetometers and support instrumentation.
Developing an Internet-based curriculum for the Earth system science education program.
Managing the Department's computer lab.
Developing and maintaining the Department of Geological Sciences' Web site.
Mass spectrometer upgrades and service.
Design and development of sample collection and data acquisition systems.
Developing software for data analysis and scientific visualization.
