Leslie Castillo earned her B.S. in Chemistry with a minor in Physics, graduating with distinction from Dominican University in River Forest, IL. During her undergraduate studies, she investigated structure–activity relationships of diazeniumdiolates synthesized from primary amines through biological assays. She also explored the structure and synthesis of benzoxanthene derivatives—fluorescent compounds incorporated into commercially available wavelength-shifting fibers such as scintillators used in high-energy physics at Fermilab. Before attending Loyola University Chicago, she worked as a laboratory technician at Tate & Lyle, supporting product development and application efforts. Leslie joined the Gates research group in the fall of 2021, where she studies the functional roles of bicarbonate in Photosystem II and how chloride substitution for other monovalent anions interrelates with bicarbonate depletion.

Grant Steiner graduated magna cum laude from Illinois State University in 2020, where he obtained a B.S. in Chemistry, a B.S. in Neurobiology and Physiology, and a minor in Psychology. Before matriculating at Loyola University Chicago for his PhD, he practiced as an Emergency Department Technician and Surgical Assistant at multiple hospitals throughout Illinois. With Professor Gates, he currently is working towards elucidating the mechanisms and induction of cyclic electron flow around Photosystem II in various photosynthetic organisms. 

Chloe Wilke graduated cum laude from the University of Missouri - Saint Louis in 2023 with her B.S. and M.S. degrees in Biochemistry and Biotechnology. During her undergraduate and masters studies, she worked in the Bauer Lab doing green chemistry organic synthesis of ferrocenophanium and curcumin derivatives. She worked at Bayer in Saint Louis for a year and a half as an associate formulation chemist working on auxin herbicide development before attending Loyola. Chloe joined the Gates Lab in fall 2025 and is studying structural and mechanistic regulation of Photosystem II-cyclic electron flow.

State transitions and PSII efficiency

My name is Lucas, and I am in my third year. I am a math major and also on the pre med track. My project studies kinetics of VIPP1, a protein responsible for membrane repair in cyanobacteria in response to laser-induced damage.

I’m a junior Biochemistry major studying how manganese is regulated and catalyzed in the water-oxidizing complex, with a focus on cobalt substitution. I'm also investigating how phycobilisome association responds to different anions.

Fun fact: I love running and I'm a steak enthusiast! 

Vipp1 activity and regulation

I’m a freshman Biochemistry major studying the role of manganese site in the water-oxidizing complex, focusing on cobalt substitution. I conduct this research under the mentorship of Alexis Diaz.
