Dr. Iran Ocana Rios
PhD (Research collaborator)

Dr. Iran Ocana Rios is currently a Post-Doctoral Fellow at Thompson Rivers University (TRU), she got a Mitacs Accelerated Award in January 2021. Dr. Ocana Rios obtained her Master and Doctorate degrees in Analytical Chemistry from Universidad Nacional Autonoma de Mexico (UNAM). She has participated in environmental chemistry research projects, and also projects of the pharmaceutical and agri-food industries. Dr. Ocana Rios specializes in sample preparation techniques, liquid chromatography, gas chromatography, and capillary electrophoresis. Her research focuses on developing analytical methods applied to aqueous, biological, environmental, and food matrices. 
Dr. Garrett Whitworth
PhD (Post-Doctoral Fellow)

Zhi Chao Guo (Michelle)
MSc. student
(Website administrator)

Zhi joined Donkor Research Group in the summer of 2013, and received her B.Sc degree in chemistry at Thompson Rivers University in 2016. Since 2013, she has participated in research projects in food safety, pharmacology, mineralogy, ecology, biology, phytology, soil science, and other fields. Of all the research areas, she is most passionate about environmental or food safety related research, which led her to choose to study and evaluate the potential of reusing industrial ash residual as a fertilizer in agriculture by monitoring the nutrients in the ash residual treated soil over a growth season using FAAS, CE and ICP-MS as her Master of Science in Environmental Science thesis project.
Lauren Okano
Research mentor
Hi! My name is Lauren, and I am a fourth-year Chemical Biology major at TRU. I joined the Donkor research group in the winter of 2020 and I have worked on several research projects including the determination of aspartame in 7-Up using UV-Vis spectrophotometry and the utilization of Fly-Ash to remove bisphenols from the environment using Capillary Electrophoresis. I have also completed a UREAP project studying the sensitive detection of nisin, a biopreservative, using Large-Volume Sample Stacking Capillary Electrophoresis. I am currently studying cannabinoid derivatives and their oxidation products called hydroxyquinones using Capillary Electrophoresis. I love research in Analytical Chemistry because it allows you to explore how small changes at the molecular level can have broad implications on a system as a whole. I am specifically passionate about research projects that use analytical chemistry to solve problems related to human health and disease. After my undergraduate degree, I hope to attend medical school where I can continue learning about the chemical foundations that are important for maintaining and improving human health.

Emily Dagasso
Undergraduate student
Hi! My name is Emily Dagasso and I am entering my fifth year majoring in Chemistry at Thompson Rivers University. I joined Dr. Kingsley Donkor’s research team in the summer of 2022 and have been working on a project involving the simultaneous quantification of cannabinoids and terpenes with the use of gas chromatography coupled with mass spectrometry (GC-MS). I have enjoyed my time so far with Dr. Donkor’s research group and am excited to continue the project in the Fall! 

Carla Figueroa
Undergraduate student

My name is Carla Figueroa and I am an international student from El Salvador going into my 3rd year of Chemical Biology. This summer, I’m helping Kingsley with a project regarding the quantification of epicatechin mostly in black teas. I will be doing this through UV-Vis spectroscopy, and I’m really excited! 

Katelyn Frymire
Undergraduate student
(Research student leader 2023)

Hi, my name is Katelyn Frymire! I am a third year Chemical Biology Major from Kamloops, BC. The project I am working on is detecting small amounts of the biopreservative nisin, using Capillary Electrophoresis. We are using a technique called Large Volume Sample Stacking (LVSS) to help us achieve higher sensitivity.
Matthew Hanks

Celena Hoang
Undergraduate student
Hi! My name is Celena Hoang and I am going into my fourth-year, majoring in Chemistry at Thompson Rivers University. I joined the Donkor research group in the Summer of 2022 and this summer, I worked on a project determining Parabens in Cosmetic Foundations using Capillary Electrophoresis.

Undergraduate student
Oleksandra Kovalenko
Undergraduate student

Abu Nadeem
Undergraduate student

Hey! My name is Abu Harera Nadeem and I am currently in my fourth year of a Bachelor of Science degree. I have been in Donkor Research Group since the second year of my degree. Using ICP-MS, I am currently working on determining the presence of heavy metals in certain types of teas.
Alena Plaxina
Undergraduate student

Malika Sharma
Undergraduate student
Hello! My name is Malika Sharma and I am a second year Science student at Thompson Rivers University. I hope to major in Cellular, Molecular, and Microbial Biology. I had the amazing opportunity to start working with Dr. Donkor as a Student Research Assistant in his lab. I worked on a project regarding the separation of bisphenols with the use of capillary electrophoresis. This is my first year working in Dr. Donkor’s research team and I am thoroughly enjoying it!
Michaela Vandermey
Undergraduate student
Hi! My name is Michaela Vandermey and I am a fourth year Chemical Biology Major at TRU. Currently I am working at Activation Laboratories as a Wet Lab and Instrument Technician. The project I will be working on is detecting heavy metals leached from disposable masks using inductively coupled plasma mass spectrometry (ICP-MS).
