Our Team

Lena Serghides, PhD

Principal Investigator, University Health Network
Assistant Professor, University of Toronto

Dr. Serghides is a Senior Scientist at the Toronto General Hospital Research Institute at the University Health Network and an Assistant Professor in the Department of Immunology and the Institute of Medical Sciences at the University of Toronto.

Her current research focus is on understanding the mechanisms that contribute to the increased risk for adverse pregnancy outcomes in women with HIV, and on the long-term effects of in utero exposure to HIV antiretrovirals.  The research is motivated by the goal of optimizing maternal and infant health in the context of infections of global health importance.

Dr. Serghides is a member of the CIHR Canadian HIV Trials Network (CTN) Women’s Working Group, and a member of the Canadian Infant Feeding in HIV Network (CIFHN).

Dr. Haneesha Mohan is a Scientific Research Associate at the University Health Network. She was previously a Postdoctoral Research Fellow under Dr. Lena Serghides’s supervision. She received a Canadian Institutes of Health Research (CIHR) Fellowship Award and a CIHR Canadian HIV Trials Network (CTN) Postdoctoral Fellowship Award.

Haneesha earned her Bachelor of Life Science (Hons.) degree in Life Sciences with a Minor in Health Geography at McMaster University. She then pursued her PhD at the University of Saskatchewan in Integrative Neuroendocrinology.

Rabia Anwar, PhD

Postdoctoral Research Fellow, University Health Network

Dr. Rabia Anwar is a postdoctoral research fellow at the Serghides lab. She completed her PhD from Humboldt University of Berlin and conducted her research at the Max Delbruck Centre for Molecular Medicine in Berlin, Germany.

She has more than 5 years of experience conducting human placental research and pregnancy-related disorders. Currently, her work is focused on identifying the impact of COVID-19 on pregnancy, especially on birth and placental outcomes and associations with race. The results of this study will shed light on the mechanisms underlying race inequalities in relation to poor pregnancy and placenta outcomes in pregnant women infected with SARS-CoV-2. 

Shreya Dhume, PhD

Postdoctoral Research Fellow, University Health Network

Dr. Shreya Dhume is a Postdoctoral Researcher at the Serghides lab (University Health Network and University of Toronto) and joined our team in July 2022. She completed her Ph.D. at the University of Manitoba with a specialization in synaptic physiology and neuropsychiatric disorders.

Currently, her work focuses on understanding the neurodevelopmental outcomes of HIV-uninfected but exposed children after in-utero exposure to antiretroviral drugs. She plans on conducting this research through primary mouse neuronal cultures and assessing the effects on neurotoxicity, oxidative stress, and mitochondrial function.

Michelle Marie Ranjbar

Ph.D. Candidate, University of Toronto (2022 – present)

Michelle completed her H.BSc. in Biology, Chemistry & Forensic Sciences from the University of Toronto. After conducting research under the supervision of Dr. Christopher Ball at the Ontario Forensic Pathology Services, and working as an analytical drug chemist for Health Canada; Michelle joined the Serghides Lab, eager to pursue her doctoral studies.

Michelle is the recipient of the NSERC Canada Graduate Scholarship (2023) and Ontario Graduate Scholarship (2023) for her work on establishing an HIV+ pregnancy murine model to investigate adverse fetal outcomes in antiretroviral drug (ARV) exposed pregnancies. Her current research focus is investigating fetal and maternal inflammatory profiles in contrasting ARV drug regimens, and she is looking forward to spending time at Stellenbosch University, collaborating with Dr. Clive Gray in the AAPH-2 cohort immune profiling studies, to further examine this.

Adriana Zutic

Ph.D. Student, University of Toronto (2024 – present)

Adriana Zutic is a 1st year direct-entry Ph.D. student in Fundamental Immunology at the University of Toronto. She completed her H.BSc. in Biological Sciences with a minor in Biochemistry at the University of Windsor. Her research interests lie in investigating the immunology of the female reproductive tract, particularly focusing on the inflammatory mechanisms driving pathology.

Adriana’s project broadly aims to examine the impact of different antiretroviral classes on the expression and activity of nutrient transporters in the placenta during pregnancy, focusing specifically on glucose, amino acid, and fatty acid transport. Outside of the lab, she enjoys baking, trying out new coffee shops, and travelling. 

Camille Blanco

M.Sc. Candidate, University of Toronto (2021 – present)

Camille Blanco is a second-year M.Sc. candidate with the Institute of Medical Science at the University of Toronto. She completed her H.BSc. in Biology with a specialization in health sciences and a minor in Philosophy at Trent University.

Camille is interested in research exploring the complex mechanisms of inflammation associated with disease and current therapies. She is currently studying ROS-related pathways in response to an integrase-strand transfer inhibitor used in antiretroviral therapy using a murine model. Outside of the lab, she enjoys basketball and has played competitively for many years.

Sebastian Acosta

M.Sc. Candidate, University of Toronto (2021 – present)

Sebastian Acosta is a second-year M.Sc. candidate at the Institute of Medical Science at the University of Toronto. He also graduated with an H.BSc. in Neuroscience and Immunology from the University of Toronto. His research interests include understanding how HIV antiretroviral exposure during pregnancy affects pregnancy outcomes and the effect of in-utero exposure to antiretroviral therapy on fetal development and neurocognitive function.

His current project is an evaluation of many currently used integrase inhibitors (Dolutegravir, Raltegravir, Bictegravir) to investigate their effects on early gestational events in a mouse model and to provide mechanistic insight into the observed adverse birth outcomes. Outside of the lab, Sebastian enjoys both playing and watching sports.

Sabrina Rasna

M.Sc. Candidate, University of Toronto (2022 – present)

Sabrina Rasna is a second-year M.Sc. candidate with the Institute of Medical Science at the University of Toronto. She completed her H.BSc. at Queen’s University in a Biotechnology specialization. Previously, she was a project student for two summers in the Serghides Lab.

Sabrina’s project, under the co-supervision of Dr. Serghides and Dr. Reina Bendayan, explores the effects of HIV and antiretroviral use on amino acid transport in the placenta during pregnancy. Outside of the lab, she enjoys outdoor recreation, case competitions and playing video games.
