Prof. Jonathan Owen
2009 -
jso2115@columbia.edu
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 and Jay Labinger. 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.

Dr. Sungho Park
Postdoc, 2021 -
sp4075@columbia.edu
Sungho is from Seoul, South Korea. He was first introduced to inorganic chemistry research in the lab of Prof. Liviu Mirica at Washington University, where he synthesized bench-stable Pd(III) complexes. After two years in the Korean military, he decided to come back to the U.S. for graduate school and joined Prof. John Berry's group at the University of Wisconsin. Sungho's work at Wisconsin focused on paramagnetic ruthenium compounds and their N–P and N≡N bond formation reactivity. After receiving his PhD, he has joined Prof. Jon Owen's lab at Columbia to investigate nanoscale metal-organic frameworks.

Dr. Daniel Cooke
Postdoc, 2024 -
Daniel grew up on Long Island and attended Binghamton University, where he received his B.S. in chemistry. While at Binghamton, Daniel gained an appreciation for and enjoyment of inorganic materials chemistry while conducting research in Dr. Wayne Jones’s lab. He then moved on to the University of Texas at Austin where he studied with Dr. Emily Que. His Ph.D. work involved designing nanoparticle conjugates as molecular imaging probes for 19 F magnetic resonance imaging. After receiving his Ph.D. in 2024, Daniel joined the Owen lab where he will apply quantum dots for biological labelling and imaging. Outside the lab, Daniel enjoys running and playing the guitar.

Dr. Augustin Braun
Postdoc, 2024 -
afb2162@columbia.edu
Gus grew up in the suburbs of Paris. He got his bachelor in 2014 and master’s in 2016 at the Ecole Polytechnique/Université Paris-Saclay in France where he worked with Dr. Greg Nocton on small molecule activation by low-valent lanthanide complexes. During his master’s, Gus worked at Harvard University in the laboratory of Prof. Tobias Ritter on the synthesis of 18F‐labeled difluoromethylarenes for PET imaging and at UC Berkeley/Lawrence Berkeley National Lab with Prof. John Arnold and Dr. Stefan Minasian on the synthesis of actinide and lanthanide nanoparticles embedded in covalent organic frameworks. Finding that the Californian weather was not that bad, he joined the laboratory of Prof. Ed Solomon at Stanford University for his PhD in 2017, studying the electronic structure of high-valent iron-oxo species involved in the H atom abstraction step of the catalytic cycle of mononuclear iron enzymes. He joined the Owen lab in 2024 to study nanodiamond formation and functionalization. When not thinking about chemistry, Gus loves to visit some new places in and around New York City, drink beer and criticize harshly the restaurants that he eats at.

William Zhang
3rd Year PhD, 2021 -
wz2588@columbia.edu
William was born and raised in Arcadia, CA outside of the Los Angeles Metropolitan Area. While pursuing his undergraduate education in Chemistry at the University of California Santa Barbara (B.S. 2021) he developed a love for synthetic chemistry, having worked in the lab of Prof. Ram Seshadri under Molleigh Preefer developing functional magnetics and materials for lithium-ion batteries utilizing solid state methodologies. While not mixing chemicals, William enjoys wandering New York City’s many neighborhoods, watching Broadway shows, listening to live music, drinking coffee, and enjoying cold weather.

Daybis Tencio
2nd Year PhD, 2022 -
dst2164@columbia.edu
Daybis was born and raised in Costa Rica. He got his B.Sc in Chemical Engineering from the University of Costa Rica, same institution that years later embraced him as an Instructor. After years working in that tropical paradise in surface and interfacial chemistry of various industrial-relevant materials he decided to come to the Big Apple and join the Owen Group. Currently, Daybis works on oxygen-terminated surfaces for quantum sensing with nitrogen-vacancy defect centers in diamond. Besides chemistry and physics, Daybis loves lifting, artistic gymnastics and ballet.

Jade Kemp
2nd Year PhD, 2022 -
jk4651@columbia.edu
Jade was born and raised in Katy, TX outside of the Houston Area. She received her B.A. in chemistry from Austin College, a small liberal arts school north of Dallas, TX. There, she had multiple research experiences, including synthetic inorganic, organic, and physical chemistry. After graduating, Jade decided to trade the humid Texas summers for brutal New York winters to pursue a PhD. in chemistry. She recently joined the Owen group and is working on nanocrystal metal-organic framework synthesis. In her free time, Jade enjoys baking, spin classes, and long walks exploring the city.

jd3847@columbia.edu
Hailing from the lush haven known as Hamilton, Ontario, Canada, Johnson earned his BSc with Honours in Chemistry from McMaster University. For his undergraduate thesis, he worked under Prof. Randall Dumont to study the Seebeck effect in organic molecular junctions. Continuing his studies at McMaster, he completed his MSc in Chemistry under Prof. Peter Kruse, where he focused on the development of solid state graphene-based chemiresistive cation sensing devices. Now at Columbia University, his main focus is on the functionalisation of quantum dots and the stabilisation of nitrogen-vacancy centres in synthetic diamonds. Outside of the lab, Johnson's interests include, but are not limited to, running, Brazilian Jiu Jitsu, labour organising, music production, and trading card games.
