Prof. Jonathan Owen
Jonathan Owen grew up in Midland, MI experimenting in the garage with the help of his father who was a chemist at the Dow Chemical Company. He studied the synthesis of asymmetric diazaphospholanes with Clark Landis at the University of Wisconsin-Madison (BS, 2000). In 2005 he obtained a PhD from Caltech while studying the synthesis and bonding of pyridine-derived N-heterocyclic carbenes and the C–H activation of methane with John Bercaw. Following his PhD, he was a postdoctoral researcher with Professor Paul Alivisatos at UC Berkeley (2005-2009) where he learned about the chemistry and photophysics of colloidal quantum dots. He joined the faculty at Columbia University in 2009 where he is currently Associate Professor of Chemistry. His group studies the coordination chemistry of colloidal semiconductor nanocrystals, as well as the mechanism of nanocrystal nucleation and growth. Jon has received several awards for his work including The 3M Nontenured Faculty Award (2010), The Early Career Award from the Department of Energy (2011), The DuPont Young Faculty Award (2011), the CAREER Award from the National Science Foundation (2012), and the Award in Pure Chemistry from the American Chemical Society (2016).

Dr. Jim Shanahan
Postdoc, 2020 -
Jim grew up outside of Worcester, MA in the town of Boylston and went on to attend the University of Rochester (B.S. 2014). When not hiding from the upstate winters in the university’s underground tunnel system, he could be found in the basement of the chemistry building in the Jones lab. His undergraduate work investigated small molecule reaction kinetics with nickel sulfide complexes. His doctoral thesis, advised by Professor Nathaniel Szymczak at the University of Michigan, focused on ligand design and assessment of unconventional hydrogen bond and Lewis acid interactions to transition metal bound small molecules (N2 and H2). After earning his PhD in 2020, he joined the Owen lab where he will apply his appreciation for ligand design, exchange behavior, and structure/function relationships to nanocrystal synthesis. Outside of the lab, Jim enjoys skiing, pyrography (woodburning), and visiting museums.

Dr. Ellie Bennett
Postdoc, 2021 -
Ellie was born and raised across the pond in Leicestershire, the self-proclaimed ‘Heart of Rural England’. Moving south she studied Natural Sciences at the University of Cambridge. There she spent her time dodging tourists, navigating 800 year old traditions and studying a lot of chemistry. Ellie spent a summer undertaking research TU Wien in Vienna, Austria, and it was here that she decided she wanted to live abroad at some point. She developed a soft spot for batteries during her undergrad whilst working on defaults in layered cathode materials in the lab of Prof. Clare Grey. After graduating, Ellie ruled out moving to London due to not wanting to live in a large city and so logically chose New York instead. Swapping a small island for the even smaller island of Manhattan, she moved to Columbia and joined the Owen Lab and is working on the synthesis of ZnS quantum dots. Outside of lab Ellie enjoys going to live music events, eating ice cream and fighting the patriarchy.

Mark is originally from Philadelphia and has been a scientist in Maine, Chicago, Seattle, and New York. He got his B.A. in Chemistry at Colby College in Maine where he discovered an interested in physical chemistry, followed by a yearlong research internship at Argonne National Laboratory in Chicago where he discovered another interest in materials science. He received his PhD in Physical Chemistry from University of Washington in Seattle in 2018, where his research involved using electro-optical and time resolved optical spectroscopy techniques to study the photophysics of organic and hybrid perovskite semiconductors in the group of Professor David Ginger. In 2018 he moved to Columbia University as a DOE EERE Postdoctoral Fellow to study the ultrafast photophysics of ferroelectric semiconductors using a variety of pump-probe laser spectroscopy and optical microscopy techniques in the group of Professor Xiaoyang Zhu. In fall 2021, he pursued a unique opportunity to work jointly as a postdoc in the groups of Professors Jonathan Owen, James Schuck (Columbia MechE), and Abhay Pasupathy (Columbia Physics) to establish a research effort at Columbia on quantum sensing with nitrogen-vacancy defect centers in diamond for imaging magnetism in two-dimensional materials. Mark is very excited to be working in all aspects of quantum with the Owen group!
