Dr. Thorman attributes his interest in geology to his grandfather, a wildcatter in the petroleum industry  who drilled the very first well that discovered the biggest on-shore post-World War II oil field in California. He gave him a geology pick for a present and took him on trips to Nevada and would take him to some oil wells, instilling in him a passion for geology and discovering petroleum. His goal in the coming years is to finish his research on metamorphic rocks. Dr. Thorman maintains that his most notable achievement was being able to teach geologists of all ages and backgrounds how to think and research geology.
