Dr. Tatek Temesgen is a Postdoctoral Associate at University of Calgary. He completed his Ph.D. in Environmental Engineering from Seoul National University. His educational background is in Chemical Engineering. His specialization and research interests are mainly in water & wastewater, bubble technology, Energy, Environment, and Sustainability. Currently, he is working on design of energy efficient nanobubble (NB) generator and characterization techniques. The NB generator is intended to be tested in different technologies including water/wastewater treatment (aeration, aerobic digestion and O3 disinfection), fuel efficiency and CO2 sequestration fields.

Dr. Sunaina is a Postdoctoral Associate at University of Calgary. She joined the group in October, 2022. She completed her Ph.D. in from Panjab University and Institute of Nano Science and Technology, India. Her current project is focused on “Generation and Characterization of Nanobubbles”. The generated NBs are planned to be used for waste water treatment. She also has research experience on designing of Type II metal oxide-metal chalcogenide heterostructures for photo-detection and photocatalytic applications. She enjoys her free time in playing badminton, drawings or travelling.

Thilina joined Kimura-Hara group in May 2018 and graduated with her PhD in December 2023. She has a B.Sc. special degree in Applied Biology with Chemistry and Computer Science studies. Currently she is analyzing toxicity of haloacetonitrile, an unregulated class of DBPs, to a non-cancerous human cell line and investigate intra and extra cellular metabolites of haloacetonitrile treated cells. Besides doing research, she loves teaching and volunteering. Since 2020, she is closely working with UC CIDE (University of Calgary Chemists for Inclusivity, Diversity and Equity), a student organization. When she is not at University, she likes to try new recipes and cycling.  

Jeas joined the Kimura-Hara lab in September 2020 and graduated with a MSc in September 2023. He holds a bachelor’s degree in chemical engineering from Mahatma Gandhi University, Kerala, India. His research work is on the development of acoustic and other gas-quantifying techniques to characterize nanobubbles. Furthermore, his research focuses on the development of a nanobubble generator with external electric fields. Apart from his research, he likes to watch movies, listen to music etc.

Jorge joined the Kimura-Hara group as a MSc student in January 2021 and graduated in December 2023. He has an undergraduate background in nanotechnology and molecular engineering. His research interest is based in the combination of analytical chemistry, nanotechnology and environmental science to be able to help in the solution of problems such as water scarcity and climate change. He worked during his undergrad studying 2D carbon-based nanomaterials generation based on simple precursors. During his free time likes to learn about movies, music, architecture and art. He's currently learning French and admires Nery Oxman and Taylor Swift.

Kumudu joined the Kimura Hara group in September 2022. She studied at the University of Kelaniya, Sri Lanka, and has a B.Sc Honors degree in Chemistry. During her undergraduate studies, she synthesized a tea waste-derived activated carbon polyacrylamide composite to remove heavy metals from wastewater. Currently, she is identifying the disinfection byproducts (DBPs) from the bromination and iodination of model organic compounds. Drawing is her favorite leisure time activity and has an interest in fashion designing

Julia joined the Kimura-Hara Group as a M.Sc. Student in late August 2023. She has an undergraduate-research background in NMR Spectroscopy-based metabolomics as well as aquatic toxicology, and she received a B.Sc. Biochemistry in April 2023 through the University of Lethbridge. Currently, she is working to elucidate the mechanisms behind the formation of nitrogenous disinfection by-products (N-DBPs) through chlorination and bromination of nitrogenous bases. Her general research interests surround environmental sustainability. During her free time, Julia enjoys listening to music, watching youtube, and learning different languages
