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 mainly 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 as a master's student and transferred to PhD in December 2019. She has a B.Sc. special degree in Applied Biology. She also studied Chemistry and Computer Science during her bachelors. During her undergrads, she specialized in analyzing nutrients in aquatic plants using various analytical techniques.  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. Beside doing research, she loves teaching and volunteering. Since 2020, she is closely working with a student EDI chapter in university Calgary. When she is not at University, she likes to try new recipes and cycling.  

Aya joined Kimura-Hara group as PhD student in Winter 2023. Aya has done her Bachelor of Chemistry (2017 cohort) at UAE university and master’s in applied chemistry (2020 cohort) at Khalifa University in UAE. She has worked on different environmental research projects that have applications in wastewater treatment. She also worked on other projects of environmental significance in biochemistry and physics. Her research interests include studying the interactions between biological agents and emerging water toxicants that pose threat to the health and environment. In her free time, Aya enjoys some physical activities including hiking and swimming.

Jeas joined the Kimura-Hara lab in September 2020. He holds a bachelor’s degree in chemical engineering from Mahatma Gandhi University, Kerala, India. His current research work in the lab is on developing acoustic and other gas-quantifying techniques for nanobubbles. Besides, his research focuses on developing a scalable 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 Winter 2021. 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 Kimura Hara group in September 2022 as a master's student. She studied at the University of Kelaniya, Sri Lanka, and has a B.Sc Honors degree in Chemistry. During her undergrads, 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 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
