Who We Are | WHAM Lab

The Water, Health and Applied Microbiology (WHAM) Laboratory

The Water, Health and Applied Microbiology (WHAM) Laboratory is split between the Ontario Veterinary College (OVC) at the University of Guelph and the Department of Epidemiology and Biostatistics in the College of Public Health at Temple University. The lab is currently led by Dr. Heather Murphy. The lab team consists of research fellows, graduate and undergraduate students interested in the field of water and health. The laboratory primarily focuses on microbiological contamination of water supplies and the subsequent impacts on public health.

Post-Doctorate Fellows

Dr. Sejin Cheong

Sejin joined the WHAM Lab in the fall of 2024 as a post-doctoral research fellow after earning her PhD in Epidemiology from UC Davis. She works on the lab’s rotational grazing and One Health project to see if rotational grazing practices improve animal and environmental health. With a background from her PhD project, which focused on the impact of grazing on fresh produce fields, she is now expanding her research to include pathogens in environmental samples, such as surface and groundwater near grazing farms. Outside of work, she enjoys cooking, watching movies, and spending time with friends.

Doctorate Students

Dr. Amilcar Bisekere

Dr. Amilcar Bisekere (DVM) is a PhD candidate in the Department of Pathobiology, with a Collaborative Specialization in One Health, at the University of Guelph. He joined the WHAM Lab in Fall 2023. A dedicated advocate for the One Health approach, his research focuses on understanding the spillover of zoonotic pathogens at human-domestic animal-wildlife interfaces, with an emphasis on the behavioral factors that shape these complex interactions. Currently, he is investigating the distribution and transmission pathways of water and fecal-borne zoonotic pathogens among people, domestic animals, and endangered lemurs in Ankarafantsika National Park, Madagascar.

He joined the WHAM Lab out of a deep concern for global health challenges and a desire to contribute to solutions. Through this opportunity, he aims to gain experience in One Health research, particularly in water quality and sanitation in low-resource settings, zoonotic disease transmission, and the use of advanced laboratory techniques. He also values the chance to collaborate with researchers committed to improving global health. Outside of research, Amilcar enjoys going to the movies and spending time with friends

Destina Mattrasingh

Destina joined the WHAM Lab in 2023 as a PhD candidate completing a degree in Pathobiology at the University of Guelph. Destina works on pathogens and AMR surveillance in animal agriculture and has been working towards applying One Health to this work. She is also enthusiastic about science outreach and access for the public as a means of equity and community0building. Outside of academia, Destina is a gardener and rollerskater.

Masters Students

Carly Dinga

Carly joined the WHAM lab in September 2023 as a M.Sc student at the University of Guelph. She is working on a project to identify effects of rotational grazing practices on pathogen presence on beef cattle farms. She initially joined the lab out of an interest in One Health research and to gain experience in different aspects of environmental microbiology. Outside of the lab, I enjoy running, reading books, and anything involving spending time outdoors.

Undergraduate Students

Julia Timmoneri

Julia joined WHAM Lab in 2021 as an undergraduate research assistant working toward her degree in Public Health with an Epidemiology concentration at Temple University. She works primarily on the WET Trial. Julia joined the lab for the abundance of laboratory experience it provides in a field she finds interesting. Julia enjoys reading, spending time with family and friends, and exploring the city of Philadelphia. She’s been a vegan for over three years!

Gopiga Dass

Gopiga Dass is an undergraduate sophomore biology major at Temple University. She joined the WHAM Lab in September 2022 and enjoys working on the WET Trial. Gopiga explains, “As someone who wants to enter the medical field, I am so grateful for the opportunity to contribute to public health research, as I believe both fields go hand in hand in improving the health and well-being of individuals and their families” When she is not working, Gopiga loves watching movies and visiting parks.

Abbey Robertson

Abbey joined the WHAM Lab in the summer of 2024 as an undergraduate research assistant on the rotational grazing and One Health project. Her interest in infectious disease and water inequality drew her to the lab. As she moves into her final year of studying biomedical science at the University of Guelph, she looks forward to continuing to contribute to the WHAM lab with a senior research project. When she isn’t studying, Abbey enjoys dance, reading, and being outdoors.

Past Students and Staff

Debbie Lee, PhD.

Debbie joined the WHAM Lab in 2018 as a Post-Doctoral Research Fellow after graduating with her PhD from Emory University in the same year. Debbie has done work with annular reactors and has been a part of the WET Trial since its infancy. She joined the lab due to her interest in drinking water quality and the WHAM Lab’s projects in this area. When she’s not working, she enjoys riding her bike up the Schuylkill River.

Miriam Wamsley

Miriam joined WHAM Lab in the fall of 2018 to assist with the planning of the WET Trial while pursuing her doctorate in Epidemiology. She focused her dissertation on spatiotemporal analyses of waterborne illness using Bayesian modeling. In her free time, Miriam enjoys singing (she’s an alto) and biking. She finds relaxation through baking. And, if she has enough free time on her hands, you’ll find her in one of the national parks in the western U.S. with her family.

Jemaneh Habtewold, PhD.

Before joining WHAM LAB in 2021 as Post-Doctoral Research Fellow, Jemaneh earned his PhD in Environmental Science in 2018. His work with the lab includes projects in the quantification of SARS-CoV-2 RNA in wastewater using a passive sampling approach, evaluating passive sampling approaches of fecal indicator bacteria in recreational water, and assessing the effects of rotational grazing on the microbial quality of surface and groundwater. He joined the lab due to his interest in the research projects that aim to quantify pathogens in environmental samples (water, soil, and feces) using advanced molecular methods including qPCR and dPCR. When he’s not working, he loves to read and watch soccer.

Erin Becker

Erin joined WHAM Lab in 2022 as an undergraduate research assistant as she works toward her degree in Biomedical Science at the University of Guelph. She works on the lab’s rotational grazing and One Health projects. She joined the lab due to her interest in the field of One Health, animals, and water safety. Erin grew up on a farm and has a particular fondness of cows. When she’s not working in the lab, she loves being outdoors, cooking, and travelling.

Erica Hollman

Erica is a Microbiology Co-Op student at the University of Guelph, who joined WHAM Lab in 2022. As a research assistant, Erica collects soil, water and animal faecal samples from various farms to analyze them for total coliforms and E. coli. She also literature searches and assists with data entry. Erica joined the lab because she is very interested in understanding the mechanisms and situations that result in the development of antimicrobial resistance, which is a large focus of the Rotational Grazing/One Health lab. She enjoys rollerblading and gardening. Erica is also learning German and Spanish.

Ilya Law

Ilya is a Masters of Pathobiology student at the University of Guelph who joined WHAM Lab in 2021. He works in the lab on projects aimed at analyzing water quality and monitoring for potential pathogens. He is working on a project that is designed to determine the optimal method for water sampling of microorganisms from specific aquatic environments. In his own words, Ilya joined the lab “to gather valuable experiences and work alongside a great and encouraging group of people. Joining this lab will also teach me new laboratory techniques that will advance my knowledge in the field and increase opportunities post degree.” When he is not working in the lab, he enjoys spending time with friends and playing basketball. He also enjoys playing the piano.
