Graduate Students



Jiwon Han (G6)

Incheon, South Korea

B.S. Chemistry, Ewha Women's University

M.S. Chemistry, Ewha Women's University


Research: My current research is focusing on metallopeptide and protein catalysts for electrocatalytic and photocatalitic reactions.


Alison Salamatian (G5)

Manchester, Connecticut

B.S. Chemistry, University of Connecticut


Research: My current research focuses on CoMC6*a, a synthetic mini enzyme that catalyzes reduction reactions. Additionally, I am characterizing the water-based CO2 reduction using semisynthetic protein catlyst CoMP11. These reactions are of interest for environmentally green and renewable fuels.



Kaye Kuphal (G4)

Guilin, China

Owensboro, Kentucky

B.A. Biochemistry, Colgate University


Research: I am excited to work on bioinorganic projects. My research focuses on electrocatalytic nitrite/nitrate reduction using inorganic catalysts. Outside of lab, I am an oboist, pianist, and creative writer.

Ryan Kosko

Ryan Kosko (G4)

Greece, NY

B.S. Chemistry, SUNY Geneseo


Research: My research focuses on heavy-metal free systems for artificial photosynthesis. I utilize organic dye photosensitizers and biocatalysts for light-driven hydrogen production.


Hafsa Irfan (G3)

 Lahore, Pakistan

 B.S. Chemistry, Lahore University of Managment Sciences

I'm excited to work in the Bren lab to amalgamate moleculary biology with photochemistry and electrochemistry! My current research would involve expressing cytochrome proteins for use as hydrogen evolution carbon dioxide reduction catalysts. 



María Fernanda Lizarazo (G3)

Bogotá D.C, Colombia

B.S. Chemistry, National University of Colombia

My research focuses on CdSe nanoparticles and porphyrin catalysts for photochemical hydrogen production. I am using electrochemical methods to characterize these catalysts and understand their reactivity.





Soraya Ngarnim (G3)

N'Djamena, Chad

Fairfax ,Virgina

B.S. Chemistry, George Mason University


My research focuses on the use of electrogenic bacteria as electron donors in photochemical hydrogen evolution systems. I am also using electrochemical systems to study the behavior of these bacteria.




Karishma Ramesh (G1)

Bangalore, India


B.S. Chemistry, St. Joseph's University, Bangalore

M.S. Chemistry, St. Joseph's University, Bangalore


I am excited to learn about photochemical proton and carbon dioxide reduction in the Bren lab!!


Alana Huynh (G1)

York, Pensylvania

B.S. Biochemistry, Ursinus College, Collegeville


I am a joint student in the Bren and Partridge groups. 


Undergraduate Students



Hafsa Mohamed


Rochester, NY


Research: I am Hafsa, pronounced the same as FAFSA. I am a rising third-year undergraduate at the University of Rochester who recently got the chance to work for a summer in the Bren Lab. I intend to continue being here since I loved this opportunity so much. I have been working on CO2 reduction in electrochemical and photochemical systems.
