Herbert Howe Lecture Series
The Herbert Howe lecture series is a public lecture series aimed at promotion of research mathematics and astronomy, organized jointly by the Department of Mathematics and the Department of Physics and Astronomy at the Division of Natural Sciences and Mathematics of the University of Denver.
The lecture series brings prominent mathematicians and astronomers to the University of Denver on an annual basis.
The series is named in honor of Herbert Alonzo Howe, a 19th century Professor of Mathematics and Astronomy at the University of Denver and Denver's first astronomer.
Herbert Howe joined the faculty in 1881 and received his doctorate in May 1884 with a thesis on a novel solution to Kepler's two body problem. He became the first director of the Chamberlin Observatory, a position in which he remained until his death in 1926.
Among his many accomplishments, he is responsible for determining the location of the original Mile High marker at the staircase of the Colorado capitol building in 1909, later replaced with an etched inscription. His measurements were more precise than those of a 1969 survey and only about 3 feet above the modern 2003 plaque.

Nitu Kitchloo
Public lecture May 18, 34pm, Olin 105 Abstraction, Reality and the Study of Mathematics (abstract) Reception May 18, 45pm, Olin Rotunda Seminar for experts May 19, 2pm, location TBA The Stable Symplectic Category and a Conjecture of Kontsevich Dr. Kitchloo received his PhD from MIT in 1998. He is a Professor and current Chairman of the Department of Mathematics at Johns Hopkins University, and a recipient of the Simons Fellowship for 20172018. His early work was on the topology of certain infinite dimensional groups known as KacMoody groups. He has since worked on various topics including Symplectic Topology, Differential Geometry, Stable Homotopy theory and Homotopical aspects of Mathematical Physics. 
Paul Hemenway
Public lecture Jan 25, 45pm, Olin 105 Gaia  The Structure and Dynamics of the Milky Way From the Brightest Billion Stars (abstract) Refreshments Jan 25, 3:45pm, Olin Rotunda Paul Hemenway started his astronomical career measuring star positions at the US Naval Observatory. He received his Ph.D. in Astronomy at the University of Virginia in 1974 measuring the positions of radio sources using Very Long Baseline Interferometry. In 1978 he became a founding member of the Hubble Space Telescope (HST) Astrometry Science Team, and used the HST Fine Guidance Sensors to help determine the coordinate system for the HIPPARCOS Astrometry Satellite. Now retired, he contributes to the Physics and Astronomy Department and the Enrichment Program at DU.

Mathai Varghese
Public lecture May 17, 45pm, Olin 105 Exotic Symmetries in String Theory (abstract) Reception May 17, 56pm, Olin Rotunda Seminar for experts May 20 AtiyahSinger index theory, fractional variant and applications Mathai Varghese received his Ph.D. in Mathematics from the Massachusetts Institute of Technology in 1986. He is the Sir Thomas Elder Professor of Mathematics at the University of Adelaide, Australia, and is a Fellow of the Australian Academy of Science. His research is mainly focussed on Geometric Analysis and Mathematical Physics. He is internationally renowned for the MathaiQuillen formalism in topological field theories, for his work on the AtiyahSinger index theory and for Tduality in String Theory in a background flux.

David Aldous
Public lecture May 28, 45pm, Olin Hall 105 Probability, outside the classroom (abstract) Reception May 28, 56pm, Olin Rotunda Seminar for experts May 29, 10am, Aspen Hall 018 David Aldous received his Ph.D. from Cambridge University in 1977. He is a Professor in the Statistics Department at UC Berkeley, Fellow of the Royal Society, and a member of the National Academy of Sciences. His research in mathematical probability has covered weak convergence, exchangeability, Markov chain mixing times, continuum random trees, stochastic coalescence and spatial random networks. A central theme in the works of Dr. Aldous is the study of large finite random structures, obtaining asymptotic behavior as the size tends to infinity via consideration of some suitable infinite random structure. 
Robert Stencel
Public lecture September 30, 45pm, Olin Hall 105 The life, times and legacy of DU's Prof. Herbert Alonso Howe (18581926) (abstract) Reception September 30, 56pm, Olin Rotunda Robert Stencel received his Ph.D. from University of Michigan in 1977. He is the William Herschel Womble Professor of Astronomy at the University of Denver, director of the DU Observatories (Chamberlin and Mt. Evans), and Colorado coordinator for the International Darksky Association. Prior to joining University of Denver in 1993, Dr. Stencel worked at NASA Houston and Greenbelt sites and at NASA Headquarters in Washington DC. He teaches astronomy courses and publishes research in astrophysics.
