Interview with Hiranya Peiris, Professor of Astrophysics at University College London and Director of the Oscar Klein Centre and Professor of Cosmo-Particle Physics at Stockholm University. Peiris describes her dual affiliation, she discusses diversity in STEM over the past year, and she surveys the current interplay between theory and observation in her field. She recounts her childhood and family heritage in Sri Lanka and the circumstances that led her family to relocate to the United Kingdom. Peiris describes her interests in math and science the opportunities that led to her enrollment at Cambridge as an undergraduate and a formative experience at JPL in California. She explains her decision to pursue a PhD at Princeton, where she worked with David Spergel on WMAP. Peiris discusses her postdoctoral appointment as a Hubble fellow at the University of Chicago to continue to work on WMAP, and her subsequent work as a Halliday fellow at Cambridge. Peiris discusses her work on the Lyman-alpha forest and her faculty appointment at UCL where cosmology was just coming into maturity. She conveys the excitement as WMAP results were becoming available and her contributions to the search for dark matter. Peiris explains why the LSST project is so significant, what it was like to win the Breakthrough Prize, and the gratitude she feels by having eminent physicists as mentors. At the end of the interview, Peiris emphasizes the importance of following inquiry into the most fundamental questions surrounding gravity and space time, and why Stephen Hawking remains an intellectual inspiration to her.
In this interview, David Zierler, Oral Historian for AIP, interviews Marius Clore, NIH Distinguished Investigator, Chief of Section of Protein NMR, Lab of Chemical Physics at the NIH. Clore recounts his childhood in London and his early interests in science, and he explains in detail the British education system that leads to specialization early in one’s undergraduate career. Clore discusses his experience at University College London, where he obtained a medical degree by age 24, and his residency at St. Charles Hospital. He describes his early interests in low temperature kinetic methods and NMR spectroscopy at Mill Hill. He describes his decision to pursue NMR as a career path, which he recognized was in its early stages at that point and which he felt was ripe for development. Clore explains how he taught himself General Relativity from Dirac’s book, and his decision to study at the Planck Institute. He describes the arc of his career at the NIH and his contributions to advancing NMR research and the intellectual atmosphere that allowed him to pursue interesting projects, including HIV research and the XPLOR program. Near the end of the discussion, Clore explains the difference between biophysics and classical physics, and why the NIH has been the ideal place to pursue his research.

Born in Toronto, Canada in 1924; University-based high school offered an excellent education in math. Attended University of Toronto for an undergraduate degree in Engineering Physics in 1945 and completed a Master’s thesis on servomechanisms in 1948. Employed as an Instructor for the Canadian Version of the GI Bill, came to MIT in 1948. Worked with L. Beranek in Acoustics lab and completed doctorate in 1952 with a dissertation about the perception of sounds shaped by resonant circuits. A research staff member of MIT from 1952-1954, he accepted a faculty position at MIT in 1955. Promoted to Associate Professor in 1957. Worked with G. Fant while on sabbatical in Sweden in 1962 and brought back x-ray films that formed the basis for early work with J. Perkell. Promoted to professor in 1963. Collaborated with D. Klatt on pioneering speech synthesis project, Klattalk, that formed the basis for DECtalk and many of speech synthesizers in use today. Traveled to England as visiting professor at University College, London 1969-1970. Served as President of the Acoustical Society of America 1976-1977. Awarded Clarence J. LeBel professorship in the department of Electrical Engineering and Computer Science at MIT in 1977. Received Gold medal from the Acoustical Society of America in 1995. Published an acclaimed book, Acoustic Phonetics, in 1998 that uses techniques of circuit analysis and signal processing to elucidate how a discrete linguistic representation is translated into articulatory movements so that their acoustic effects produce speech communication.
