Thank you, Caroline. Good afternoon, everyone, and thank you for joining us today. We had a great first quarter here at Personalis, and I'm excited to update you on our progress. We achieved revenues of over $20 million this quarter and also delivered over 2,000 molecular tests. I can't express how proud I am of the entire Personalis team for hitting those milestone numbers. I'm thrilled with our progress and the whole organization is geared up to win an MRD. Let me back up a bit for those of you new to our story to explain what we're doing to improve outcomes for cancer patients. Personalis is a leader in the fast-growing MRD or Minimal Residual Disease testing market, which uses a blood draw instead of imaging or invasive biopsies to monitor therapy effectiveness and to detect cancer recurrence. The MRD market is expected to mature into a $20 billion market and with our ultra-sensitive MRD test next personal, we believe Personalis is positioned for success. Our technology is able to detect cancer when there's only about one fragment of tumor DNA circulating in a million DNA fragments in blood. Our tumor profiling platforms and tests are cutting edge. We're able to see more with high sensitivity and as a consequence, our platforms and tests are used by many of the world's top biopharma companies to improve clinical trial results, personalized treatment, empower a new generation of therapies. We're pushing hard this year on our win in MRD strategy, and our first quarter continued the strong momentum established in 2024. Our revenue was $20.6 million in the first quarter and resulted from solid progress across all three sectors of our business. Our biopharma revenue grew to $13.6 million, driven by strong growth in the use of NeXT Personal. Our enterprise and VA revenues were also robust and our clinical diagnostic business had its highest quarterly revenue to date. Our cash and cash equivalents at the end of the quarter are $185.7 million, which gives us a comfortable runway to drive our growth objectives. We are reiterating our guidance of $80 million to $90 million in revenue for 2025, 30% to 40% quarter-over-quarter growth in molecular results and achievement of reimbursement at least two indications in 2025. Now, let's dive into the business by outlining progress metrics key to our win in MRD strategy. First is clinical usage. We are making great strides in driving NeXT Personal into the nation's oncology community. We're following a unique partner centric strategy to commercialize NeXT Personal by working with Tempus, one of the country's leading labs, leveraging their approximately 200 person sales force to bring our assay to market. We delivered 2,184 molecular tests this past quarter, which is an increase of 52% compared with 1,441 molecular tests delivered in the fourth quarter of last year. Now, to underscore this progress further, we've grown our molecular test usage approximately 650% over Q1 of 2024. We believe this performance is very encouraging evidence that our Win-in-MRD strategy is working. As physicians order the test on patients and use the results to direct patient care, feedback has been positive and retention is high. Approximately 40% of our MRD positive results are in the ultra-sensitive range, and our physicians are telling us this is an important differentiator. This allows for a leap forward in earlier detection of cancer recurrence, more discrimination and monitoring therapy, and importantly, the ability to have more confidence in a negative MRD result. We believe that our Win-in-MRD strategy will be powered by combining better data with a strong experience, and we're spending time in this phase of our Win-in-MRD strategy on being best-in-class, in terms of customer care and a robust experience. The second dimension of our strategy is deepening clinical evidence and achieving reimbursement. Our early evidence generation is focused on three indications: breast cancer, lung cancer, and IO therapy monitoring. We've previously summarized the findings from investigators at Royal Marsden for breast cancer, VHIO for IO therapy monitoring, and TRACERx for lung cancer. These three indications and their results are powering three different Medicare submissions. In March, the Royal Marsden paper was published and we submitted to Medicare for breast cancer reimbursement. When the VHIO and TRACERx papers are accepted for publication, we plan to submit for Medicare for reimbursement for immunotherapy monitoring and lung cancer respectively. We continue to be confident that we will achieve reimbursement at least two of the indications in 2025, and I look forward to updating you as the year progresses. We were excited this quarter to unveil our first data in colorectal cancer or CRC. Now, this indication is important within the oncology community as the lion's share of MRD clinical data and significant reimbursement to date has been developed in this indication. Our work is in response to feedback from physicians that there is an unmet need for a more sensitive approach in CRC. Now, what that means is that doctors want to identify more patients right after surgery that are going to recur because that is a critical time to make treatment decisions. They also want a test that can spot the cancer even when it occurs in a distant organ, such as the lung. And lastly, they tell us they want to be more confident in a negative MRD result. Delivering on these needs will better guide patient management in the post-surgical CRC setting. At the AACR meeting this past week in Chicago, our collaborators at British Columbia Cancer showed early analysis from a prospective study called VICTORI. The BC cancer dataset presented included 71 patients with a median follow-up of 15 months and showed NeXT Personal was able to detect 100% of recurrences, prior to imaging. Importantly, 87% of the cancer relapses were detected in the early landmark window of two to eight weeks post surgery with the majority of those detections in the ultra-sensitive range that we unlock with our assay. Additionally, 100% of metastatic relapses were detected by the assay, including all distant lung metastasis. The improved performance from our approach, we believe, could enable a better way to manage CRC patients in the future. Now, during the last call, I discussed how a physician using NeXT Personal was able to spot a recurrence of breast cancer, and their patient was able to access therapy ahead of imaging and the impact this had on the patient's life. Today, I'd like to spotlight a patient that has Stage 3 colorectal cancer that was diagnosed last summer. His physician treated him with neoadjuvant chemotherapy and then surgically removed the tumor. At that point, the physician had the option to either observe or treat the patient with adjuvant chemotherapy based on clinical guidelines. To help make that decision, the oncologist ordered the NeXT Personal test approximately four weeks after surgery. The test was positive, and it was in the ultra-sensitive range, which suggested the patient was at a high cancer recurrence risk, prompting the physician to immediately start adjuvant chemotherapy for the patient. The physician then used the NeXT Personal test to monitor response to therapy. Reassuringly, subsequent tests showed clearance of circulating tumor DNA after starting chemotherapy, suggesting a good response for treatment for the patient. It's an example like this where our ultra-sensitive test can positively impact a patient's journey that motivates our work. Now, while the CRC data is preliminary, the results are encouraging and put us on a path to potentially submit for publication over the next year. Working to mature the data, we'll begin our drive towards reimbursement for our fourth indication, and we expect success in the large CRC market to be a significant driver of revenue in the next few years. As a reminder, we expect our collaborators within our first three indications, breast, lung and IO therapy monitoring, to be presenting results in future conferences and these studies to continue to fuel a robust publications roadmap. In breast cancer, we're working with Vanderbilt, Johns Hopkins and other institutions on the PREDICT study, which is an approximately 180 patient study in early triple negative breast cancer and HER2-positive breast cancer. And we have an ongoing prospective study called B-STRONGER-1 and triple-negative breast cancer that's now enrolled approximately 100 patients from approximately 30 sites. We also have ongoing studies with Dana-Farber on HER2-positive patients, the Institut Curie on an approximately 100 patient early-stage triple-negative breast cancer and with MD Anderson. In IO therapy monitoring, we're working with UKE at two different melanoma studies, with Duke in a study of gastric cancer patients and with UCSD in a pan cancer IO therapy study across eight different cancers types. In early-stage lung cancer, we're continuing our work with the TRACERx team and we're pushing forward on an additional study called DARWIN 2. As the data from these studies begin to enter the public domain, we expected to highlight the importance of our ultra-sensitive approach to detecting ctDNA and allow physicians to better manage and treat patients with cancer. The third area we are tracking is progress with our biopharma customers. The ultra-sensitive approach we are pioneering provides biopharma customers the ability to accelerate clinical trials with greater accuracy and can translate to significant savings for our biopharma customers by getting answers sooner. The past quarter, our revenue from this segment was $13.6 million. This was 39% growth over the first quarter of 2024 and is driven by increasing adoption of our MRD platform, both by existing and new biopharma customers. We saw record revenue in MRD, and we are tracking to generate year-over-year growth of 300% to 400% in MRD revenue from biopharma customers. Importantly, we've landed two large additional customers and expect each of them to generate annual revenue in the $5 million range this year. Those wins are attributed to the decision by those clients to adopt NeXT Personal. Our second platform, ImmunoID NeXT, remains the platform of choice for biopharma companies, developing immunotherapies and is also utilized by Moderna in its individualized neoantigen therapy programs. Market demand for ImmunoID remains strong and we continue efforts to broaden our tumor profiling product portfolio with new versions developed to capture additional business from biopharma that have grown to trust Personalis as a partner. The year is off to a strong start at Personalis, and we are laser focused on our strategy to Win-in-MRD. Our employees, collaborators, and partners working hard to improve the journey for cancer patients with an ultra-sensitive MRD approach, and in the process, we're creating a special company. We're grateful to all of our investors that are part of our journey to pioneer this ultra-sensitive MRD testing market. We're running fast towards multiple milestones in 2025, and it's shaping up to be a significant year for the company, as we execute on our growth drivers and most importantly, a significant year for patients with cancer, as we redefine the way cancer is managed. With that, I will now turn it over to Aaron to review our financial results.
