Dr. Stuart Turvey

Principal Investigator

As a pediatric immunologist and clinician-scientist, I study two major health problems that are informed by clinical realities and that have immune system dysfunction as key to their pathogenesis:

  • Asthma: the most common chronic non-communicable disease of childhood; and
  • Primary immunodeficiency diseases: devastating and often life-threatening genetic disorders in which parts of the immune system are missing or dysfunctional. 

My research approach is sensitive to the child's developmental course and aims to define the underlying cellular, molecular, and genetic abnormalities responsible for disease. The new knowledge we generate improves diagnosis and disease management. Ultimately, our work identifies new, individualized strategies to treat these challenging chronic child health conditions.

Outside of the lab, I enjoy running, gardening and spending time with my family.

Research Associates

Dr. Bhavi Modi

Research Associate

I am a human geneticist by training with over six years of experience in women's health research. My doctoral work involved investigating the genetic mechanisms of complex female reproductive disorders and pregnancy complications. My current postdoctoral research in Turvey and Wasserman labs focuses on utilizing applied genome analysis methods towards the study of rare genetic disorders. These projects allow me to integrate next-generation analysis techniques with biological theory for a more functionally informative approach that has a better chance of impacting healthcare management. My work is driven by a keen passion to help families going through diagnostic odysseys — a passion that is fueled by personal experiences. This makes coming to work an exciting and gratifying experience.

Outside of the lab, I love spending time with my family. I am an avid reader, I love to sketch and paint, build elaborate puzzles and work on small home decor projects.

Dr. Charisse Petersen

Research Associate

I have a PhD in Microbiology and Immunology and consider myself to be an advocate for tiny humans and tiny microbes alike! Despite their bad reputation, the vast majority of bacteria that we like to call ‘germs’ are non-pathogenic and likely even helpful. This especially includes the ones that colonize us as infants and create little communities on and inside our body. These bacteria belong to our ‘microbiota’, and they help infants develop into healthy children and adults. They make sure we get important nutrients from our food to help us grow. And they even train our immune system how to know which signals, or antigens, are harmful or not to prevent the development of asthma and allergies. The best part of my job is working with studies like the CHILD study to shine a light on all the wonderful things that our microbiota does. The more that we know, the better we are at protecting these important bacteria in order to keep infants and children healthy.

In my free time (what’s free time?!) I can be found chasing my two tiny humans around and playing in the garden.

PhD Student

Prior to moving to Vancouver and pursuing PhD studies at UBC, I obtained my BSc in biology from Pepperdine University (California, USA). I currently study associations between microbial populations found in the gut and the occurrence of chronic allergic diseases within the CHILD study cohort. My work focuses on identifying therapeutic targets for prediction and prevention in order to, hopefully, help children and families live fuller lives without the burden of these conditions.

In my free time, I enjoy running, hiking, spending time with family and friends, trying new restaurants, and visiting coffee shops to have a nice latte and read.

Simran Samra

Simran Samra

PhD Student

I completed a bachelor’s degree in Honours Biochemistry and a master’s degree in Experimental Medicine from the University of British Columbia. After my master’s degree, I wanted to pursue disease-oriented medical research. Thus, I joined the Rare Diseases Discovery Hub at the BC Children’s Hospital Research Institute. Working at the Hub on projects that had the potential to directly improve a patient’s life was very fulfilling and made me realize my passion for precision medicine. 

In May 2023, I started my Ph.D. training under the supervision of Dr. Stuart Turvey. My project focuses on using precision medicine in pediatrics to discover and characterize novel monogenic disorders. This research will help further our understanding of human biology, improve patient care, and optimize treatments.

In my free time, I enjoy reading, running, and trying new restaurants and cafes.

Maryam Vaseghi

Maryam Vaseghi

MD/PhD Student

I completed my BSc in bio-psych and my MSc in medical sciences both at McMaster University before moving to UBC. I am currently an MD/PhD student at the Turvey Lab. During my undergrad and master's I became very interested in immunology, so I decided to pursue doctoral studies, studying more immunology! My research at the Turvey lab focuses on discovering and understanding gene mutations that result in primary immunodeficiencies leading to severe allergic/atopic conditions from birth, also known as primary atopic disorders (PADs). Our aim is to screen for children born with PADs across Canada, find the molecular cause of their previously undiagnosed atopic condition, perform functional characterization of their immune cells and potentially, repurpose existing therapeutics to treat their condition.

Outside of the lab, I enjoy baking, dancing, practicing taekwondo and going on long walks around Stanley Park!
