Catherine Cullingham, PhD

I am an Associate Professor in the Biology Department at Carleton University. I grew up on a small dairy farm on the edge of the bustling metropolis of Burks Falls (Pop: 1000!). There I spent a lot of time outdoors and interacting with animals. I always had a passion for math and biology and decided to do my undergraduate studies in molecular biology and genetics at the University of Guelph. Finishing my undergrad, I had decided I hated lab work, and research was not for me. A year after not finding any meaningful employment, and after some great interactions with researchers at a plant research station, I jumped into a Master’s at Trent University. From there I was hooked, and transferred to the PhD program where I used population and landscape genetics to examine the risk of raccoon rabies spread into Ontario. From there I did my postdoctoral work at the University of Alberta, where I initially worked on understanding spread-risk of chronic wasting disease in deer, and then switched from mammals to plants to investigate the genetics of pine trees to understand spread-risk of mountain pine beetle. This research has formed the foundation of my current research lab. But, because animals and plants are bags of DNA to me, I am happy to explore any interesting question that we can apply a population genetics approach to.

Meet the Team

PhD Candidate

Marc Avramov

Marc started his grad studies in 2021 under Dr. Cullingham, with co-supervision from Dr. Ludwig (PHAC) and Dr. Lapen (AAFC). His work revolves around understanding the factors associated with mosquito-borne disease presence in urban, rural, and natural environments. He employs a multidisciplinary approach, utilizing landscape genomics, vector ecology, and GIS tools to unveil habitat and climatic conditions linked to the rate and direction of viral transmission. By studying the relationships between vector/host interactions and virus activity, Marc aims to create tools to help better track and predict disease hotspots. Outside of research, he enjoys fishing, hiking, travelling, DJing, and hanging out with friends and family.

PhD Candidate

Melanie Beaudin

Melanie joined the GP3 lab when completing her BSc: a biodiversity assessment of Microgastrinae (Hymenoptera: Braconidae) in the Ottawa area. As of 2023, she began her graduate studies, which involve taking a population genetics approach to investigate insect decline due to climate change and anthropogenic activity. Melanie has also taken an interest in a disjunct population of cacti near Kaladar, Ontario. She is performing a population genetics study to hopefully gain a sense of the population’s origins and time of establishment. Melanie’s topics of interest include parasitology, polyploidy, sex determination systems, and sex allocation. You may contact her at melaniebeaudin@cmail.carleton.ca.

PhD Candidate

Caroline Grela

Caroline is a graduate student who joined the GP3 lab in 2022, to begin her master’s program at Carleton University. This comes after completing her honours bachelor’s degree in biopharmaceuticals with a specialization in genomics at uOttawa. Her academic interests include population genetics, bioinformatics, and ecology. Her research focuses on a genomic analysis of the Mountain Pine Beetle in its range expansion, as a part of the TriA-FoR project. In her free time, Caroline loves doing arts and crafts or being outdoors in nature.

PhD Candidate

Mina Sadeghiniaraki

Mina, is a PhD student in Dr. Catherine Cullingham's lab. Her work centers on unraveling the genetic mechanisms that empower jack pine (Pinus banksiana), to withstand pests, and pathogens, specially Mountain Pine Beetle and Western gall rust. By focusing on deciphering the genetic code of jack pine, she aims to pinpoint the genes responsible for resistance and harness this knowledge for the benefit of our forests. In addition, Mina delves into identifying shared genetic factors within conifers that confer resistance to both climate change and pests or pathogens, aiming to uncover common genes responsible for these dual adaptations. This research not only deepens our understanding of conifer resilience but also provides crucial insights for the conservation and sustainable management of our forests in a changing world.

PhD Student

Mehra Balsara

Mehra completed her undergraduate degree in wildlife biology and conservation at the University of Guelph. She recently finished her Master’s degree in biology at Western University, where she studied the evolutionary effect of trophy hunting on horn characteristics in Yukon thinhorn sheep. Currently, she has joined the GP3 lab in 2024 as a lab technician and has started as a PhD student in 2025, where she will be studying the landscape genetics of West Nile disease spread in Canada.

PhD Student

Grace Gardner

Grace is a PhD student who recently completed her M.Sc. in the lab in 2025. Before joining GP3, she earned her bachelor’s in forensic science at Trent University. Grace’s research is in landscape genetics. During her master’s, her project focused on identifying local adaptation to the environment in jack pine. As a PhD student, she is now studying resistance to pathogens and climate change in several conifer species. Outside of academics, she enjoys getting involved with the BGSA, helping organize events and hosting trivia, as well as drawing and being outdoors.

PhD Student

Saanchi Singh

Saanchi joined the labs of Dr. Cullingham and Dr. Galindo-Gonzalez (CFIA) in 2024 after completing her BSc in biochemistry at the University of Waterloo. Her current research goal is to develop a protocol to detect noxious weed seeds from the seed soil bank and bulk seed using DNA metabarcoding in order to improve detection efficiency of pests. Her academic interests include plant molecular biology, genetics, and bioinformatics. Outside of research, she enjoys hiking, dancing, travelling, and baking.

M.Sc Student

Shelby Atkinson

Shelby is an undergraduate student in Honours Biology working alongside Melanie Beaudin in Dr. Cullingham’s Lab to investigate a disjunct population of the cactus Opuntia fragilis near Kaladar, Ontario. Her work focuses on using a population genetics approach to examine the genetic diversity and potential origins of the population. Her academic interests include ecology and population genetics, specifically in plants and insects. Outside of academia she enjoys puzzles, reading, baking, and spending time outdoors.

M.Sc Student

Bianca Tassi

Bianca is a graduate student in the Cullingham Lab examining population structure methods and their robustness across different life histories. She completed an undergrad degree in molecular and cellular biology at Carleton in June 2024. Her undergraduate thesis project centered on using genomics to estimate jack pine resiliency to mountain pine beetle in the boreal forest. Outside of academia, she enjoys travelling, reading, bingeing TV, and snuggling with her dog.

Undergraduate Student

Rayan St-Amant

Rayan is an undergraduate student in molecular and cellular biology working with Marc Avramov in the GP3 lab under the guidance of Dr. Cullingham. He is currently studying the role of white-tailed deer in the transmission of mosquito-borne arboviruses, specifically Jamestown Canyon Virus. He hopes to continue working on this transmission framework to further characterize vector-reservoir interactions. Outside of academia, he enjoys playing jazz on his trombone.

Undergraduate Student

Grace Whalen

Grace is an undergraduate student completing a Bachelor of Science with a major in Biology. She joined the GP3 lab in the September 2026. In the lab she is completing her honors project on Jack Pine population genetics. Outside of school, Grace enjoys painting, travelling and taking care of her plants.
