Research Scientists and Postdoctoral Scholars

Supriya Ghosh

I am from West Bengal, India, and I completed my PhD research work collaboratively from Indian Institute of Technology Mandi and Lund University Sweden. My PhD research focused on photophysics of inorganic and organic-inorganic hybrid nanocrystals and microcrystals. I also conducted my research work in some excellent European facility in Germany and Sweden. I joined the Kohler group in 2022. My research projects in the group are currently on metal oxide photocatalysts and Photophysics in DNA-metal nanostructures.

Sasha Ilina

I completed my PhD under supervision of Prof. Justin Hodgkiss in Victoria University of Wellington, New Zealand. My research was focused in ultrafast dynamics of the skin pigment eumelanin. After completing my PhD I spent some time as a Research Assistant in Dr. Nathaniel Davis's group in Victoria University of Wellington. I joined Kohler group in 2022 to continue my research of eumelanin's photophysics using a combination of bottom-up and top-down approaches.

Graduate Students

Alex Hanes
Xanthine Vibrational Dynamic
Lily Kinziabulatova
Melanin Biochemistry

I joined Kohler group in 2020. I am studying the photophysics and the structure-function relationship of melanin using a bottom-up approach.

Bach Pham
Metal Oxide Dynamics

I am from Saigon, Vietnam and I graduated from Texas Christian University with a B.S. in Chemistry in 2019. My undergraduate research under Dr. Benjamin Sherman focused on tin(IV) oxide-based dye-sensitized solar cells. I joined the Kohler group in 2021 as an inorganic chemistry student. My research projects in the group are currently on photoexcited charge carrier dynamics of cerium oxide, its hybrid system with organic molecules, and its heterojunction with another semiconducting material. 

Meera Madhu
Melanin Biochemistry

I am from Kerala, India. I graduated with Integrated B.S.-M.S. from Indian Institute of Science Education and Research, Thiruvananthapuram, where I worked under Dr. Mahesh Hariharan on photophysical properties of organic chromophore assemblies. I joined the Kohler group in 2021. My current research focuses on excited state dynamics of eumelanin from a top-down perspective.

Visiting Students

Bárbara Fornaciari

I'm from Londrina, Brazil and graduated in Chemistry from Londrina State University and completed a Master in Bioinorganic Chemistry from University of Sao Paulo (2020). I'm currently a PhD student at University of Sao Paulo under Dr. Mauricio S. Baptista and joined the Kohler group in 2021 for a collaborative dual degree between OSU and USP. My research focuses on nanoparticles based on melanin analogues, its excited states characterization including singlet oxygen emission.
