I began a tenure-track Assistant Professor position in the College of Pharmacy at the University of Manitoba Rady Faculty of Health Sciences and Affiliated Research position at the Karolinska Institutet in January 2019. My research aims to identify precision medicine approaches to neurological diseases and psychiatric disorders. I have been recognized by the European Commission (Horizon-2020), and the Canadian Institutes of Health Research (CIHR), including the prestigious Marie Skłodowska-Curie Actions-Horizon 2020 European Fellowship (€180K) and the Government of Canada Banting Fellowship (application ranked #3 Nationwide, $140K CAD) with over 20 awards during my PhD alone, totalling over $960K in personal salary awards, and $1.8M in peer-reviewed operating and team grants. I currently have 15 publications (10 first-author), and many others in preparation. Most recently, I was a Postdoctoral researcher at the Karolinska Institute with Professor Patrick Sullivan and the KI-Psychiatric Genomics Institute to harness my collaborative, problem-solving abilities that I have developed during my doctoral training and apply them to the intricate issues faced today by the psychiatric community. My projects involved utilizing the Swedish National Register data, the Sweden Schizophrenia Study, and other Psychiatric cohort studies.
Project 1: Identifying Clinical, Demographic, & Genomic Risk Factors for Treatment-Resistant Psychiatric Disorders
Approximately 30-60% of those with psychiatric illnesses respond poorly to therapy and may experience devastating effects. Those with treatment-resistant psychiatric disorders have higher mortality, costs, and longer hospitalizations compared to treatment-responders. Schizophrenia (SCZ), major depressive disorder (MDD), bipolar disorder (BIP), and anorexia nervosa (AN) are aetiologically similar, often co-aggregate in families, and have overlapping common variant genetic architectures. These psychiatric disorders (several of which are hierarchically arranged) are at least partly aetiologically similar. These conditions have clinical comorbidity; if one disorder is present, there is substantial risk for one or more other disorders. I am unaware of any systematic assessment of genetic, clinical, and demographic factors associated with treatment-resistance across SCZ, BIP, MDD, and AN simultaneously. Previous studies evaluated single disorders and were limited by small samples and did not consider a range of risk factors.
I am aiming to investigate whether risk factors common to treatment-resistant SCZ, MDD, BIP, or AN exist and I believe that a core treatment-resistant or “clinically severe” cluster of individuals exists across the four psychiatric disorders. This work has recently been accepted for publication and will be available shortly.
Project 2: Prediction of mortality using DNA methylation age in schizophrenia
DNA methylation levels vary over the course of life. Surprisingly, pre-selected combinations of methylation array probes can be used to estimate “methylation age” (mAge), which usually correlates highly with chronological age. Occasionally, mAge is greater than chronological age, and this difference is a replicated predictor of all-cause mortality. SCZ is associated with significantly higher mortality and decreased life expectancy. We tested the association between mAge and mortality in individuals with SCZ and controls, hypothesizing that mAge predicts subsequent death in SCZ. This work has been published in Translational Psychiatry.
Past (and on-going) Research:
Multi-omic Studies in MS
My research PhD dissertation Also included the first-ever genome-wide association study for a serious adverse drug reaction in MS for Which The created new collaborations between three countries, encompassing 8 institution. The study findings were clinically relevant and Statistically significant; with the identification of a novel biomarker highly associated with the drug reaction. This work was published in Nature Genetics. An on-going study that I am affiliated with is investigating biomarkers of lymphopenia from one of the newly approved MS therapies. The protocol for this work was published in BMJ Open.
Epidemiological Investigations Into the Multiple Sclerosis (MS)
My Ph.D. Training focused on the epidemiology and pharmacogenomics of MS with Dr. Helen Tremlett (U. of British Columbia). I defined the prevalence of liver injury due to interferon beta therapy in MS to be approximately 1 in 50 exposed interferon beta, Utilizing a mixed epidemiological approach (Kowalec et al, Exp Opin Drug Saf 2014). More recently, as a Postdoctoral Researcher in the Pharmacoepidemiology of MS Research Group, in a joint study, I evaluated the association between comorbidity and the risk of relapse in a prospective, multi-center study in individuals with MS. This work was recently published in Neurology.
