Through hands on experience and advanced academic training, I have developed strong expertise in research, applied machine learning and statistics, and am passionate about using my skills to create data driven solutions to solve real world problems. I completed my MSc in Computer Science at Univeristy of Toronto supervised by Joseph Jay Williams. During my masters, I worked on issues pertaining to statistical inference from data collected by Multi-Armed Bandit algorithms in online educational experiments. In particular, I developed methods which balance statistical inference properties and reward maximization, and validated these methods in real world online education settings. I also worked on designing, deploying, and analyzing randomized experiments in online education. In the past, I have worked on applications of Deep Learning in fall detection as well as agitation detection at IATSL, under the supervision of Shehroz Khan and Alex Mihailidis.
