Sydney JENSEN
Lab & Field Manager
Sydney has a BSc in Environmental Biology with Honours from the University of Saskatchewan, and a MSc in Biology from the University of Regina. Her MSc research examined greenhouse gas dynamics in Prairie wetlands (sloughs) and dugouts, as well as how greenhouse gas dynamics vary over the open-water season.
Iman SALEHI
Lab Technician
Iman is a Research Associate at IECS, where he is responsible for analytical instruments and technical assistance. He holds a Master's degree in Analytical Chemistry and a BSc in "Chemistry - Information Technology." Iman is enthusiastic about learning and passionate about new technologies. He enjoys method development, troubleshooting various systems, and programming.
Nasim SOLTANIKHARAJI
Research Assistant
Nasim earned a master’s degree in Analytical Chemistry from Shahrekord university in Iran. She works as a Research Assistant in the laboratory of Dr. Nicole Hansmeier and Dr. Tzu-Chiao Chao where she is involved in monitoring SARS-CoV-2 levels in wastewater samples for COVID-19 surveillance in Saskatchewan.
Jess ROTARIU
Lab Technician
Jessica received her BSc Honors in Biology with a concentration in Cellular and Molecular Biology from the University of Regina. She also completed her MSc at the University of Regina, where she studied the effects of thermal exposures on the stress responses in early life stage lake whitefish. Jessica’s research interests include cellular/molecular biology and environmental physiology. Currently, she is enjoying working as a lab technician in the Chao/Hansmeier Lab.
Jay SAVALIYA
Research Assistant
Jay received his BSc in Biology from the University of Regina and is a research assistant in Drs. Chao & Hansmeier lab. He is leading the research on the effects of second-hand cannabis smoke exposure. His interests ranges from tissue histology to pathogen-host interactions using visualization techniques such as atomic force microscopy and laser scanning confocal microscopy.
Amir CHEGOONIAN
Postdoctoral Researcher
Amir is a postdoc researcher who holds a PhD in Geography from the University of Waterloo. His background is in machine learning and remote sensing, and he is currently working with Dr. Peter Leavitt to develop innovative ways to monitor water quality in Canadian lakes using remote sensing technologies.
Cale Gushulak
Postdoctoral Researcher
Cale is a paleolimnologist focused on the impacts of land-use and climate change on water bodies over multiple time scales. His research projects include examination of eutrophication trends in prairie lakes since colonization and the experimental fertilization of agricultural reservoirs with the prolific N-fertilizer urea.

Ryan RIMAS
PhD candidate
Ryan is a graduate student in the department of biology in the Finlay Lab. He earned his MSc degree in Geograpy from York University in Ontario. His research interests include carbon dynamics and climate change impacts on small shallow freshwater bodies. For his PhD research, he is studying how climate change induced desiccation affects greenhouse gas production and carbon sequestration in agricultural reservoirs in the Northern Great plains, within southern Saskatchewan.
Michael MENSAH
PhD Candidate
Michael's PhD research is examining the limno-biophysical controls of sulphates in small farm ponds (dugouts and wetland ponds). Michael is also testing the effectiveness of phytoremediation and dredging in delivering water quality improvement. By understanding how surrounding soils, vegetation and other landscape features impact water sulphate concentrations, we can better target potential mitigation opportunities for improving water quality for agriculture.
Keerthikrutha SEETHARAMAN
PhD Student
Keerti is a PhD student of Prof. Kerri Finlay in FAST lab. Her research focuses on providing a local-scale understanding of the water quality of several of the lakes of Saskatchewan.

Samina THAPA
MSc Student
Samina is a graduate student in the department of biology at the University Of Regina. She also holds a Master’s degree in Medical Microbiology from Kantipur College of Medical Sciences in affiliation to Tribhuvan University , Nepal. Currently, she studies the impact of low doses of antibiotics on Salmonella with the help of proteomic and microscopic approaches in the Chao and Hansmeier Labs at IECS. She is also interested in observing host and pathogen interactions at the molecular level using Salmonella as the model organism. Outside of lab she loves doing yoga, meditation and acrylic paintings, going for hiking as they are integral part of her life.
Sonja REUTER
MSc Student
Sonja received her BSc in Life Sciences at the University of Potsdam in 2018 and is currently finishing up her MSc in Biology in the Chao/Hansmeier lab. In her studies she worked on establishing a wastewater surveillance for SARS-CoV-2 in Southern Saskatchewan.

Jay VAVADIA
Undergraduate Student
Jay is a fourth-year undergraduate student majoring in Biology and minoring in Kinesiology. He is currently working in the Leavitt Lab and assessing the extent of cyanobacterial toxins, Microcystin, β-N-Methylamino-L-alanine (BMAA), and Anatoxin-a in the Qu’Appelle River system and agricultural reservoirs throughout southern Saskatchewan. Jay is interested in understanding if the levels of these cyanotoxins in the water reservoirs of southern Saskatchewan are considerable enough to threaten aquatic and public health.
