Research Scientist

University of Alberta, Cross Cancer Institute
Aug 2013 - Sep 2023 · 10 سنوات 1 شهر

Led projects investigating the regulation of endogenous human LINE-1 (L1hs) by Argonaute proteins (AGO1/AGO2) and small RNA pathways in nuclear and cytoplasmic condensates.
Developed the "Condensate Checkpoint" model and established cellular/biochemical assays to detect checkpoint breaching and quantify downstream cGAS/STING pathway activation.
Investigated the spatial organization of biomolecular condensates (Stress Granules, Processing Bodies, DDR foci) and their role in regulating endogenous nucleic acid metabolism and innate immunity.
Studied the intersection of genome instability, PARylation, and chromatin silencing at DNA double-strand breaks (DSBs).
Constructed stable mammalian cell lines (U2OS) for the purification and characterization of large, complex ribonucleoprotein assemblies (Ago1/Ago2 complexes) for structural and biochemical analysis.
Co-developed and drafted a successful CIHR grant application in collaboration with Dr. Michael Hendzel.
Mentored graduate students and assisted undergraduates in experimental design, molecular biology techniques, and data analysis.
