Question: At which university does the phycisist upon who's bestseller "Calabi-Yau" is based teach?

full_context: Document 1: Homological mirror symmetry: Homological mirror symmetry is a mathematical conjecture made by Maxim Kontsevich. It seeks a systematic mathematical explanation for a phenomenon called mirror symmetry first observed by physicists studying string theory.
Document 2: Einstein's Gift: Einstein's Gift is a play written by Canadian playwright Vern Thiessen in 2003. Through the recollections of Albert Einstein, the play focuses on the life and career of German chemist Dr. Fritz Haber, who helped improve living conditions with his work on nitrogen fixation. His work was later used by the German army to produce chlorine gas used in Second Battle of Ypres in the First World War. As Dr. Haber becomes increasingly involved with the German army, the play depicts how his actions and newly forged military connections affect his relationship with his wife, Clara, and his assistant, Otto. As his passion in science intertwines with nationalistic pride, Haber manifested himself a scientist devoted to a country that never accepted his Jewish origin.
Document 3: Categories: On the Beauty of Physics: Categories: On the Beauty of Physics is a non-fiction science and art book edited, co-written, and published by American author Hilary Thayer Hamann in 2006. The book was conceived as a multidisciplinary educational tool that uses art and literature to broaden the reader's understanding of challenging material. Alan Lightman, author of "Einstein's Dreams", called "Categories" "A beautiful synthesis of science and art, pleasing to the mind and to the eye," and Dr. Helen Caldicott, founder and president of the Nuclear Policy Research Institute, said, "This wonderful book will provoke thought in lovers of science and art alike, and with knowledge comes the inspiration to preserve the beauty of life on Earth."
Document 4: Stephen Hawking: Master of the Universe: Stephen Hawking: Master of the Universe is a documentary television series produced by the television broadcaster Channel 4. The subject of the series is British theoretical physicist Stephen Hawking, known for his work on black holes, who is also the presenter of the series. The series includes interviews with astrophysicist Kim Weaver, Bernard Carr, a student of Hawking's, and three theoretical physicists: Michio Kaku, Edward Witten, known for his work on superstring theory, and Lisa Randall. The first episode premiered in 2008, twenty years after the publication of Hawking's bestselling popular science book "A Brief History of Time". The title is derived from a "Newsweek" cover, which labeled Hawking "Master of the Universe".
Document 5: This Beautiful City (play): This Beautiful City is a play with music by the investigative theatre company The Civilians. The play engages with "the expansion of the Evangelical movement in Colorado Springs" as well as the gulf between the Evangelical and secular communities in the region. It was written by Steve Cosson and Jim Lewis from interviews conducted by Associate Artists Emily Ackerman, Marsha Stephanie Blake, Brad Heberlee, Brandon Miller, Stephen Plunkett, and Alison Weller, with music and lyrics by Michael Friedman, and directed by Steve Cosson. The play first opened in March 2008 at the Actors Theatre of Louisville Humana Festival of New American Plays, followed by successful runs at Studio Theatre in Washington, D.C. and the Center Theatre Group in Los Angeles, CA. The piece premiered in New York City in the winter of 2009 at the Vineyard Theatre. This Beautiful City was nominated for Drama Desk, Drama League, and Lucille Lortel Awards
Document 6: Surely You're Joking, Mr. Feynman!: "Surely You're Joking, Mr. Feynman!": Adventures of a Curious Character is an edited collection of reminiscences by the Nobel Prize-winning physicist Richard Feynman. The book, released in 1985, covers a variety of instances in Feynman's life. Some are lighthearted in tone, such as his fascination with safe-cracking, studying various languages, participating with groups of people who share different interests (such as biology or philosophy), and ventures into art and samba music. Others cover more serious material, including his work on the Manhattan Project (during which his first wife Arline Greenbaum died of tuberculosis) and his critique of the science education system in Brazil. The section "Monster Minds" describes his slightly nervous presentation of his graduate work on the Wheeler–Feynman absorber theory in front of Albert Einstein, Wolfgang Pauli and other major figures of the time.
Document 7: Lisa Randall: Lisa Randall (born June 18, 1962) is an American theoretical physicist working in particle physics and cosmology. She is the Frank B. Baird, Jr. Professor of Science on the physics faculty of Harvard University. Her research includes elementary particles, fundamental forces and extra dimensions of space. She studies the Standard Model, supersymmetry, possible solutions to the hierarchy problem concerning the relative weakness of gravity, cosmology of extra dimensions, baryogenesis, cosmological inflation, and dark matter. She contributed to the Randall–Sundrum model, first published in 1999 with Raman Sundrum.
Document 8: Andrew Strominger: Andrew Eben Strominger ( ; born 1955) is an American theoretical physicist who is the Director of Harvard's Center for the Fundamental Laws of Nature. He has made significant contributions to quantum gravity and string theory. These include his work on Calabi-Yau compactification and topology change in string theory, and on the stringy origin of black hole entropy. He is a senior fellow at the Society of Fellows, and is the Gwill E. York Professor of Physics.
Document 9: Eva Silverstein: Eva Silverstein (born October 24, 1970) is an American physicist and string theorist. She is best known for her work on tachyon condensation in string theory and resulting resolution of some spacetime singularities (with Adams, Polchinski, and others). Her other significant research contributions include the construction of the first models of dark energy in string theory, some basic extensions of the AdS/CFT correspondence to more realistic field theories (with Kachru), and the discovery of a predictive new mechanism for cosmic inflation involving D-brane dynamics (with Tong and Alishahiha).
Document 10: Steven Gubser: Steven Scott Gubser (born 4 May 1972) is a professor of physics at Princeton University. His research focuses on theoretical particle physics, especially string theory, and the AdS/CFT correspondence. He is a widely cited scholar in these and other related areas.
Document 11: Eric Zaslow: Eric Zaslow is an American mathematical physicist at Northwestern University. He attended Harvard for his Ph.D in Physics. His research focuses on mathematical questions arising from duality symmetries in theoretical physics such as mirror symmetry. With Andrew Strominger and Shing-Tung Yau, he formulated the SYZ conjecture.
Document 12: Calabi-Yau (play): Calabi-Yau is a 2001 play written by playwright Susanna Speier with songs and music by Stefan Weisman, based on physicist Brian Greene's national bestseller "The Elegant Universe".
Document 13: Matthew Kleban: Matthew Benjamin Kleban is an American theoretical physicist who works on string theory and theoretical cosmology. He is an associate professor at New York University, a member of the Center for Cosmology and Particle Physics, and a former member at the Institute for Advanced Study. His contributions to physics include:
Document 14: Calabi conjecture: In mathematics, the Calabi conjecture was a conjecture about the existence of certain "nice" Riemannian metrics on certain complex manifolds, made by and proved by . Yau received the Fields Medal in 1982 in part for this proof.
Document 15: Brian Greene: Brian Randolph Greene (born February 9, 1963) is an American theoretical physicist, mathematician, and string theorist. He has been a professor at Columbia University since 1996 and chairman of the World Science Festival since co-founding it in 2008. Greene has worked on mirror symmetry, relating two different Calabi–Yau manifolds (concretely, relating the conifold to one of its orbifolds). He also described the flop transition, a mild form of topology change, showing that topology in string theory can change at the conifold point.
