A Research Scientist pioneering in Molecular Biology, where curiosity meets innovation. With a passion for unraveling the intricacies of life at a molecular level, harnessing cutting-edge technologies to advance our understanding of biological systems, my goal is to work towards designing novel therapeutic modules of complex disorders.
Feb 2024 - Present
My research involves working in a multidisciplinary team comprising of biomedical researchers, clinicians, computational biologists, and data scientists. The teams’ overarching goal is to develop biomarker panels for accurate diagnosis of a range of medical complications and conditions such as organ transplant rejections, interstitial lung diseases, allergic rhinitis and occupational asthma. I independently lead operations for a laboratory at the Core-1 molecular phenotyping facility in the research wing of St.Paul’s hospital and NetCAD, the research wing of Canadian Blood services located at University of British Columbia, Vancouver. I orient the research team with experimental designs, execution, data generation and analysis, grant preparations, budgeting and laboratory management.
MITACS industrial postdoctoral fellow:
MITACS awarded me an industrial postdoctoral fellowship, to research on RNA therapeutics for neuro-inflammatory diseases, in collaboration with an industrial partner, DeutraMed and academic partner, Université de Sherbrooke. I led the project towards develop D-Lock TM Stabilization Technology. This is deuterium-based mRNA stabilization technology aimed at developing a stable RNA-based vaccine. This patented technology offers a promising solution to the significant cost and challenge of cold-chain logistics. Upon successfully developing a stable in-vitro synthesized mRNA, I explored the therapeutic role of an innate immune component of pattern recognition receptor called NLRX1 in multiple sclerosis. I tested it in experimental mouse model of MS using lipid nanoparticles. I explored the immunogenicity of the stable mRNA in human and mouse cell lines.
Postdoctoral Scientist, Translational Research in Occupational Asthma:
Biotalent Canada awarded me a grant to research on blood-based biomarker discovery, in collaboration between PROOF Centre for excellence and Centre for Heart & Lung Innovation. I executed a discovery study to develop biomarker for occupational asthma subtypes and validated using machine learning analytic tools. During this tenure, I conceptualized genetic analysis to identify SNPs associated with asthmatic responses. My work during this period led to discovery of cholinergic synapse pathway gene polymorphisms association with allergen-induced late asthmatic responses, which was then published in European respiratory journal.
I worked with the Canadian Longitudinal Study on Aging (www.CLSA.ca). This work was with a national team of collaborators from the University of Toronto, University of Victoria, Ryerson University, University of Ottawa, and MacEwan University to examine various health determinants and their relationships with physical, mental, and cognitive health outcomes. Another project I worked on, investigated practitioner-led peer supported personalized nutrition approaches that are based on nutrigenomics provided in an interactive online virtual environment. Part of the study included collecting eye tracking data to better understand how people interact with health information presented in online social environments. The goal of the project was to discover whether these approaches can foster positive and sustained healthbehaviour changes in emerging adults (18 to 25 years).
Innovation in Science Pursuit for Inspired Research (INSPIRE) awarded me a 5-year research grant to pursue my graduate training. My research was focused on exploring the genetic and immunological factor underlying the onset and clinical symptoms of Schizophrenia. I primarily investigated the role of prenatal infections on neurodevelopment, its influence on the behavioural patterns by evaluating the genetic and expression profile of immune molecules of cytokines- IL-10, IL-6, TNF-α, IFN-γ and HLA-G and assessed the impact of drug interventions on the expression profile of these molecules. I also explored the role of genetic compatibility between the mother and offspring (patients) at the HLA-G gene loci in conferring risk. Parallelly I was involved in study participant recruitment,screening, assessments and sample collection. As part of screening and assessments for schizophrenia research, I worked directly with the study participants, performed phlebotomy, collected medical, treatment history and drew family pedigrees/genograms.
In the research wing of VRR diagnostic laboratory, I worked on a project that focused on the genetic cause of Diabetic foot ulcer. I addressed the question of whether genetic polymorphisms of endothelial nitric oxide have a crucial role in the vascular endothelium to increased oxidative stress, thereby increasing the risk for diabetic foot ulcer. To facilitate this research, I independently established collaborations with St John’s National Academy of Health Sciences, Bangalore and Vellore Diabetes Centre from where I was able to obtain human specimens. During another research project at Indian Institute of Technology (IIT), Madras, I worked towards understanding the agarase or carragenase producing bacteria under halophilic conditions. The goal was to isolate these organisms to be able to exploit their function to control many applications including algae bloom, avoid biofouling etc.
