While only an itinerant researcher, my past research interests lie in computational physical chemistry, where I enjoy the study of chemical bonding. Computational chemistry applies the principles of Quantum Mechanics to solve chemical system-sized problems. Calculations are usually performed on large computer workstations with some taking several days to complete. Computational Chemistry is one of the fastest growing fields in chemistry. Now chemists can estimate the stability of compounds as well as reaction pathways before they enter the laboratory allowing for more efficient use of resources.
As for education, I am interested in developing effective ways for the computer to be incorporated into the curriculum, and in the development of "discovery" and guided inquiry lab exercises.
Prior to teaching I worked in a number of chemistry related jobs. The most interesting were my stint as a chemist at a hazardous waste removal firm and as a research assistant at the radiocarbon dating laboratory at the University of California, Riverside. I began my teaching career teaching 7th-9th grade science in 1990. After taking a leave of absence I began teaching at California State Polytechnic University, Pomona, where I greatly enjoyed the college level. In June of '96 I joined the Chemistry faculty here at Grossmont.
I currently serve on the San Bernardino County Sheriff's Cave Rescue Team (www.sbsar.org). We are a CA OES Type I wilderness search and rescue team, and Type 2 cave rescue team. We specialize in confined space, high angle technical rescue. We are an associate member of the Mountain Rescue Association with a certification in Technical Rock Rescue and Wilderness Search.
Until moving to the San Diego area, I worked with Riverside County Fire as the County Training Officer for the Radio Amateur Civil Emergency Service (RACES). Our job was to provide communications support for large wildland fires or other disaster relief related activities.
Related to the above, I enjoy amateur radio (ham radio) where I especially like VHF/UHF contesting and propagation studies. Also, just about any outdoor activity that includes a trip to the desert is great fun.
