摘　　要：My first exposure to Don Helmberger’s work was during a seismology class in my 2nd year in college where several students,including myself,were to present on Grand and Helmberger(1984).It was over my head,but seeing the beauty of the seismograms,tracking the upper mantle triplication,and what it revealed about the Earth was just transformative.During my time as an undergraduate at Berkeley,I also digitized(Dreger and Savage,1999)and forward modeled seismic data under the advisement of Dr.Doug Dreger(a Helmberger student)for about two years,had an academic advisor who went to Caltech(Dr.Mark Richards)and took a couple of courses from Dr.Lane Johnson(Don's friend from Minnesota).Little did I know the path I needed to take was already laid out-I just had to follow it.
