          <p>
             Hi there! I'm a Master's student at the <a href="https://www.utoronto.ca/">University of Toronto</a>, advised by <a href="https://www.trailab.utias.utoronto.ca/steven-waslander">Professor Steven Waslander</a>
             in the <a href="https://www.trailab.utias.utoronto.ca/">Toronto Robotics and AI Lab</a>.
             I am affiliated with <a href="https://robotics.utoronto.ca/">University of Toronto Robotics Institute</a> and
             <a href="https://vectorinstitute.ai/">Vector Institute</a>.

            <!-- <div id="more-bio" style="display: None">
              <br>
              <p>MORE BIO HERE IF NEEDED</p>
            </div> -->
            I obtained my Bachelor's degree in <a href="https://engsci.utoronto.ca/">Engineering Science</a> (Machine Intelligence major) from the <a href="https://www.utoronto.ca/">University of Toronto</a>.
            <br><br>
            My research lies at the intersection of machine learning, computer vision, and robotics.
            My previous and current work focuses on object detection, uncertainty quantification, multi-object tracking, and visual anomaly detection for autonomous driving and space robotics.
            Going forward, I am interested in exploring visual representation learning, generative modeling, multi-modal perception and 3D scene understanding.
            <br><br>
