Hello, everyone, and welcome to Xilab's fourth quarter and full year 2024 earnings call. Today's call will be led by Dr. Samantha Du, Xilab's founder, CEO, and chairperson. She will be joined by Josh Smiley, President and Chief Operating Officer, Dr. Rafael Amado, President and Head of Global Research and Development, and Dr. Yajing Chen, Chief Financial Officer. Jonathan Wang, our Chief Business Officer, will also be available to answer questions during the Q&A portion of the call. As a reminder, during today's call, we will be making certain forward-looking statements based on our current expectations. These statements are subject to numerous risks and uncertainties that may cause actual results to differ materially from what we expect due to a variety of factors, including those discussed in our SEC filings. We will also refer to adjusted loss from operations, which is a non-GAAP financial measure. Please refer to our earnings release furnished with the SEC on February 27, 2025, for additional information on this non-GAAP financial measure. At this time, it is my pleasure to turn the call over to Dr. Samantha Du. Thank you, Christine.
