Saikat Banerjee

I come from West Bengal, India. Inspired by my first Chemistry teacher, I majored in Chemistry and completed my B.Sc. from the University of Calcutta in 2012. Then, at the Indian Institute of Technology, Kanpur for my M.Sc,. I worked on synthesizing fluorescent chemosensors for heavy metals. After that I came to the University of Minnesota in the fall of 2014 to pursue my graduate studies. I have joined the Que lab to study the chemistry of various non-heme iron complexes.


Shuangning Xu

Shuangning is originally from Changchun, China and received his BS in chemistry from the U of M. As an undergraduate, he worked in the Que group in his senior year on bio-inspired catalysis by non-heme iron catalysts. Now he has joined the group as a graduate student to continue his study.




Waqas Rasheed

Waqas was born in the small city of Gujranwala in Pakistan. Still in his teens, one of the first computer programs he wrote was a periodic table that displayed information on elements when the elements were clicked. He decided later on that the chemical information he encoded was far more interesting (and less frustrating) than coding itself and pursued his undergrad degree in chemistry at LUMS, a private university in Lahore. In 2013, he flew to Minnesota to pursue graduate studies on model complexes of metalloenzymes, and he is currently studying the reactivity of non-heme iron complexes.



Subhasree Kal

Subhasree comes from India. Fascinated by the colorful chemistry of transition metals, she decided to major in chemistry in her B.S. She completed her masters in chemistry from Indian Institute of Technology (IIT) Kanpur before coming to the University of Minnesota to pursue graduate studies. She joined the Que group to study oxidation of hydrocarbons and olefins by bioinspired non-heme iron catalysts.




Patrick Crossland

Originally from the bustling metropolis of Lewisburg, Pennsylvania, Pat obtained his BS with honors in chemistry from the College of William and Mary, in Virginia. While an undergrad, he studied proton reduction catalysts under the direction of Dr. William R. McNamara and wrote his honors thesis on a series of cobalt catalysts. Pat officially joined the Que group in the fall of 2015 and is currently working on trapping and characterizing reactive intermediates spectroscopically.



Sheng Yuan

 Sheng was born and grew up in Shanghai, where he received his B.S. in chemistry from East China Normal University. His undergrad research focused on synthesizing chiral porphyrins and studying their applications in organic synthesis under Prof. Hu’s guidance. In 2015, Sheng decided to switch fields and came to Prof. Que’s lab studying the force behind high-valent iron oxo complexes.



Chase Abelson

Chase was born and grew up in Los Angeles. Staying in Southern California for school, Chase obtained his Bachelor's degree from Pitzer College in Claremont, CA. He completed his senior thesis on the synthesis of chiral amino acid derivative ligands for asymmetric hydroamination under the direction of Dr. Adam R. Johnson at Harvey Mudd College. Chase joined the Que group in the fall of 2017 and is currently working on studying the reactivity of non-heme iron complexes.

Courtney Elwell

Courtney is from the capital region of New York and obtained her B.S. in chemistry from Union College (Schenectady, NY) in 2014. There she worked in a synthetic bioinorganic lab under the direction of Prof. Laurie A. Tyler. She then joined the Tolman lab at the University of Minnesota in pursuit of her Ph.D. in chemistry. She is now a fifth year graduate student, co-advised with Prof. Larry Que, studying the structure and reactivity of mono- and dicopper complexes supported by biomimetic ligands.

Ju Byeong Chae

Ju Byeong comes from South Korea. He received his BS degree in Seoul National University of Science and Technology. He studied chemosensor during his MS degree period under the direction of Prof. Cheal Kim. During this time, he became interested in inorganic complexes and wanted to study more about their catalytic abilities. He joined the Que lab as a visiting scholar in 2019 and is studying non-heme iron catalysts.

Ahmed Mohamed

Born and raised in Cairo, Ahmed obtained his IB diploma in Munich and then flew further west across the Atlantic to pursue a degree in chemical engineering (with a minor in CS). When not working on nonheme iron complexes in the Que lab, Ahmed plays and watches soccer and enjoys his free time swigging coffee as a way to get inspiration from the grad students with whom he is working.
