his year’s virtual symposium provides an opportunity for undergraduates from Mid-Hudson colleges to present their research in the chemical sciences. All areas of chemistry, environmental science, molecular biology, and related fields are welcome. A poster session will allow students to share their work, followed by an award ceremony and an invited lecture.
Symposium Program 3:30–4:00 PM: Participant Check-In 4:00–4:45 PM: Poster session A 4:45-5:30 PM: Poster session B 5:30–6:00 PM: Awards and Announcements 6:00 PM: Invited Lecture by Dr. Nasrin Hooshmand, Senior Research Scientist Georgia Tech Laser Dynamics Laboratory

Guest Speaker: Theodore Gray, author of The Elements “The Periodic Table: Completing a Work of Ages”
Abstract: The periodic table has been an inspiration since its outlines were first published 150 years ago. At first an inspiration for scientists to fill in its missing pieces. Then an inspiration for students to learn about the rich patterns and symmetries of chemistry. Now an inspiration to all of us as an example of what can be accomplished when a community of dedicated researchers works together over a span of seven generations to complete a task that only the last few could hope to see finished in their lifetime.
Speaker Bio: Theodore Gray is the co-founder of Wolfram Research, Inc, makers of Mathematica, and the author of The Elements, the internationally best-selling book and App on the beauty of the periodic table, translated into 25 languages. He is the creator of the BAFTA award-winning, 2013 iPad App of the Year Disney Animated, and proprietor of periodictable.com and mechanicalgifs.com. His most recent project is a book on the functional beauty of mechanical devices, to be published in the fall of 2019.

Guest Speaker: Dr. Bart Kahr, Department of Chemistry, New York University
“Why are Crystals Straight?”
Abstract: Why are Crystals Straight? In chemistry, we know the vast majority of what we know about molecular structure from the scattering of X-rays from crystals. Diffraction works so well because crystals have long range translational symmetry. In fact, crystals are straight, by definition. Their sharp edges and flat faces, so unlike most everything else in Nature, flash forth their symmetry, translational symmetry first and foremost. However, we have shown in the past decade that a large fraction of simple molecular (organic) crystals can be made to grow with helicoidal morphologies, as structures with curvature that are decidedly not straight. Studies of the mechanisms that give rise to these apparent distortions in crystals that twist as they grow has developed into a meditation and a program of computation aimed at understanding why and when crystals develop translational symmetry. We have come to see translational symmetry not as a requirement of crystallinity, but rather as an imperfect compromise between free energy and size.
About the Speaker: Bart Kahr was born in New York City in 1961. He studied chemistry with I. D. Reingold at Middlebury College, with Kurt Mislow at Princeton University (Ph.D., 1988), and with J. M. McBride at Yale University. He was a faculty member at Purdue University from 1990 to 1996 and at the University of Washington, Seattle from 1997 to 2009. After which, he returned to his hometown where he is currently Professor of Chemistry in the Molecular Design Institute at New York University. Kahr's research group studies the growth, structure, and physical properties of complex organized media. Bart also practices the experimental history of chemistry and crystallography, that is those aspects of the development of science of can only be informed by contemporary laboratory experiments. In recent years, he has been advocating for the changes in the way that universities and government agencies manage scientific misconduct. In 2014, he was named NSF Distinguished Lecturer in the Mathematical and Physical Sciences.
