Thank you, Caroline. Good afternoon everyone and thank you for joining us. I'm very proud of our team at Personalis as we continue to fight cancer and help patients with our novel technologies. For those of you joining one of our calls for the first time, welcome. Personalis is one of the leaders in the fast-growing MRD testing market. MRD stands for minimal residual disease and involves using blood, which is commonly called a liquid biopsy instead of imaging or invasive biopsies to monitor therapy and to detect cancer recurrence after treatment. The MRD market is expected to mature into a $20 billion market. And with our first-of-its-kind ultra-sensitive MRD test, Personalis has emerged as a leader in this space. Our technologies are able to spot cancer when there's only about one fragment of tumor DNA circulated and 1 million DNA fragments in the blood. Our platforms are used by many of the world's top biopharma companies to improve clinical trial results by new ways to personalize treatment and power a new generation of therapies. Earlier this year, we laid out our strategy to drive Personalis to $100 million in revenue in 2025. Now, this operational milestone has at its core three growth engines and its effect has been to shift us into a higher growth mode. In the second quarter, we achieved revenue of $22.6 million, up 35% year-over-year. This growth was driven by our biopharma business, which grew 117% year-over-year, led by strong demand for our tumor profiling product that is used to create personalized cancer vaccines for patients as well as increasing demand for our MRD product NeXT Personnel. Our strong Q2 revenue also helped us to increase our guidance for the full year by $3 million, and we now expect full year revenue in the range of $79 million to $81 million. We're particularly pleased to have been able to deliver this top line growth, while also making improvements to both our cost and margins as Aaron will cover shortly. I'll now review progress this quarter on our three growth engines. First, the first growth engine, Win-in-MRD is the most important as we focus on turning Personalis into a clinical diagnostic powerhouse. As I noted, MRD testing uses a liquid biopsy to find evidence of minimal residual disease or cancer recurrence and to monitor therapy effectiveness. We laid out our Win-in-MRD strategy six quarters ago, and we've been executing on its four pillars; one, focus on cancer types where an ultra-sensitive approach can unlock significant value for patients, payers, and partners. Two, drive reimbursement by developing robust clinical evidence and partnering with the top global collaborators. Three, leverage our deep relationships to accelerate adoption by biopharma partners and power our revenue growth by the use of NeXT Personnel and clinical trials; and four, commercialized NeXT Personnel with a partner-centric model. Now, to delve into the first pillar, we previously explained how we're developing evidence to support NeXT Personnel's clinical usage and reimbursement in lung cancer, breast cancer, and IO therapy monitoring. The data across multiple studies now indicate we're able to seek answer recurrence earlier, and this holds out the promise that those patients can seek treatment sooner with potentially better outcomes. The clinical studies that have been done to-date indicate we can detect cancer many months ahead of imaging. The data also suggests that patients who are classified as MRD negative, meaning our test doesn't detect circulating DNA from the tumor, largely do not experience recurrence. Having more confidence in a negative result may allow a doctor to de-escalate patients from unnecessary therapies and procedures, potentially avoiding toxicities and ultimately saving the healthcare system money. Our focus on these indications is intentional, and our data is demonstrated that NeXT Personnel can win in these markets. To elaborate a bit on our approach, lung cancer and breast cancer shed very little DNA in the blood, so cancer is difficult to detect without an ultra-sensitive approach. Lung and breast cancers can be aggressive when they recur, so early detection is critical. For patients on IO therapy, we believe the potential decision to switch treatment requires the insights from monitoring that are provided by our ultra-sensitive test. These factors make breast cancer, lung cancer and therapy monitoring the ideal indications for us. In October of 2023, we launched the first commercial ultra-sensitive MRD test into the clinic. NeXT Personnel is being marketed alongside our Medicare reimbursed tumor profiling test, NXDX, which is used to help put patients on appropriate therapy. We started our commercial journey with just 10 doctors in an early access program, and we've been adding incrementally. As we previously stated, our intention is to gradually add more doctors into the program until we receive reimbursement. Our quarter-over-quarter growth continues to be healthy as we delivered 561 clinical tests in the second quarter, a 66% increase from the 338 results delivered in the first quarter of this year. In addition, Tip has commenced their commercial launch of NeXT Personnel late in the second quarter and we expect this to fuel additional growth. Early feedback has been that clinicians are seeing a leap in actionability from our approach. If you remember, we report circulating tumor DNA in the blood down to one part per million, which means that if there is just one fragment of tumor DNA circulating in about 1 million DNA fragments in the blood, we expect to see it and quantify it. This is a leap forward in the field. These extra analytic sensitivity we report on with our NeXT Personnel test on Maska region that has previously been hard to see consistently. We call that region the ultra-sensitive MRD range. About 30% of the ctDNA positive samples in our clinical testing have been in this ultra-sensitive range. That is a jump in the actionability of MRD testing and means physicians can see cancer recurrence earlier, have more discrimination and monitoring therapy and have more confidence that patients with negative ctDNA results are, in fact, cancer-free. Indeed, we've had many anecdotes related from our early access doctors that the ultra-sensitive range is allowing them to see cancer sooner and intervene with the patient to get them the management they need and also to consider deescalating therapy when our test determines patients are negative for ctDNA. For example, a female patient from the Northeast receiving therapy for breast cancer tested positive with our NeXT Personnel test. Her physician saw low traces of cancer in the ultra-sensitive range for over several months. And luckily for this patient, the detected levels trended downwards until the patient's cancer finally became undetectable. Continued monitoring can potentially help inform taking patients like this all therapy in the future and provide reassurance to both the doctor and the patient. Moving to our second pillar, we're focused on building and publishing clinical evidence to gain reimbursement and continue to work with many of the top thought leaders around the world. In previous calls and during the ASCO webinar, we talked about the importance of our work with two of the leading cancer centers in Europe, Royal Marsden breast cancer and Valdarna and immunotherapy monitoring. Both of these collaborators have provided access to studies that are broad and comprehensive. In the case of Royal Marsden and the Institute of Cancer Research in the U.K., which are one of the leading global institutions in breast cancer. The study included patients across the major breast cancer subtypes, including HR-positive -- HER2-positive and triple-negative breast cancer in patients were followed in this study for a medium of six years. The study results were highlighted at ASCO during a podium presentation and the results were compelling. NeXT Personnel detected early stage breast cancer a medium of 15 months before imaging scans for patients. For Falahebron, our VHIO, the work is in pan-cancer and included greater than 120 patients across 18 different cancer subtypes. The study show the NeXT Personnel to be potentially used to predict immunotherapy response for patients. Similar to what we are seeing with our breast cancer studies, our test is detecting traces of cancer well ahead of imaging scans. These Royal Marsden results in the VHIO studies for immunotherapy monitoring join our TRACERx work in lung cancer to form the backbone of our efforts to gain Medicare reimbursement. Investigators in all three of these studies were Marston, DHIO and TRACERx are working to submit manuscripts to peer-reviewed journals, which is a key step for us ultimately to submit for Medicare reimbursement. Once those manuscripts are published, we can then submit the individual dossiers for each of the indications to Medicare. There were two other data sets at ASCO that highlighted NeXT Personnel are also worth noting. One was a study with Dana-Farber for HER2-positive patients that showed NeXT Personnel was correlated with outcomes in patients receiving neoadjuvant therapy. Neoadjuvant therapy is given to these patients before surgery to try to shrink the tumor before the cancer is removed. In the second study, this one with Duke, deepened the data indicating NeXT Personnel could be used to predict immunotherapy response. The third pillar of our NeXT Personnel strategy is to leverage our biopharma relationships to drive the use of NeXT Personnel and clinical trials. We're engaged with the most -- excuse me, with most of the world's top biopharma companies and have continued to generate excitement around our NeXT Personnel test, most recently from discussions at ASCO. Customers want and need an ultra-sensitive approach to ensure that the most appropriate patients enter into clinical trials. For example, we believe that our ultra-sensitive assay means that patients testing negative are much most likely to have a recurrence. Our biopharma customers can then expect that these patients are less likely to benefit from a therapeutic intervention, holding out the promise the NeXT Personnel be an excellent approach to optimize biopharma trials. We have booked millions of dollars of revenue from biopharma customers from MRD projects to date and expect the growth to accelerate. Now, move on to the fourth and final pillar. Commercializing NeXT Personnel in the clinical market using a partner-centric model. In December, we announced our key partnership with Tempus to commercialize NeXT Personnel in the clinics with oncologists and recently, Tempus announced the launch of our products to their customers. To quickly review, we expect to leverage Tempus' 200-plus salespeople channel to co-commercialize NeXT Personnel accelerate growth. Personalis will be responsible for processing samples in our lab, obtaining reimbursement, invoicing health insurance payers and patients under the arrangement, while paying Tempus fair market value for the commercial services they provide to us. Overall, the deal is worth approximately $30 million for Personalis should all milestone payments be triggered and then Tempus fully exercised their warrants. We expect this to allow us to ramp up commercial efforts quickly with minimal additional cash investments. We're now on the Tempus requisition and we're processing samples sent to our lab. The goal for the balance of the year is to purposely grow our efforts together, learning how to work seamlessly as partners, integrating our business systems, and refining our message to oncologists. This way, we're set to drive accelerated growth together on the backside of reimbursement approval. The Tempus relationship is working extremely well to-date. Our cultures and our teams work well together, and we're confident that we're creating something great for doctors, patients, and payers. While we made strides with our first growth engine, our Win-in-MRD strategy to establish NeXT Personnel as a leading MRD test. We've also made progress with our second growth engine, leveraging our ImmunoID NeXT platform to deepen relationships with biopharma customers who use the offering to pioneer new therapies. Our biopharma business grew 117% year-over-year, and we had solid performance across our product portfolio. Customers primarily use our ImmunoID NeXT platform in two ways. First, they leverage our platform to power translational research and find new biomarkers and insights that can enable their drug discovery efforts. Second, companies in the personalized cancer vaccine or the PCV market use our platform to create a molecular fingerprint of a patient's tumor to develop personalized therapy. We previously told you about our partnership with Moderna in which Moderna is utilizing our platform in their mRNA cancer program. Moderna and its partner, Merck are enrolling patients, and our collaboration with Moderna is an important driver of revenue for us in 2024 and 2025. We have several other partners that work in this space as well. The third engine of our growth is growing our Personalis inside approach as we service enterprise customers. In these relationships, partners adopt our platforms and technologies to power their solutions. For example, Natera has leveraged our Exome platform as a part of their MRD product to help them scale, while they work to build in-house capabilities. As planned, they've reached the point where they can now run the product in their lab, and we expect to wind down our work with Natera by the end of 2024, and we have no intention to extend the current commercial arrangement. With other strategic parts of our business accelerating quickly, PCV, biopharma MRD projects, and our clinical diagnostic business, the additional capacity will shift to support those critical parts of our business. I should also note, we're having other discussions exploring scaling up enterprise work in 2025. A second important enterprise relationship is the VA. Now, the VA utilizes our whole genome sequencing capabilities to power the Million Veteran Program, a national research program looking at how change in lifestyle affect health in veterans. We've helped power this program with the VA for over 10 years. The VA informed us this quarter that they plan to renew the contract another year, and we expect to receive a new purchase order by the end of September. Before I turn it over to Aaron, I have a couple of important corporate updates. First, we recently completed an agreement with Myriad Genetics to cross-license patent estates covering tumor-informed approaches to detect minimal residual disease, or MRD. Both companies value tumor-informed approaches for cancer patients and have developed deep foundational patent estates in the field and each sees the benefits of an ultra-sensitive approach is key to making MRD testing to standard-of-care. The agreement we entered into help solidify each company's freedom to operate in the MRD market and broadens access to the benefits of MRD testing for cancer patients. Personalis and Myriad are each pioneering tumor-informed genome scale approaches to power ultra-sensitive MRD test enabling cancer recurrent detection early and more refined therapy monitoring and alternative approaches. Additionally, we settled our litigation with Foresight, which resulted in us granting them a license to our MRD patents. This is a great outcome for Personalis. One, our IP that we've developed over many years is valuable. We were able to show that, and we'll be paid royalties moving forward. And secondly, we can focus on running our business and putting litigation costs behind this. Both the cross-license agreement with Myriad and the settlement should give investors confidence in the value of our IP, the strength of its protection, and our ability to create value from it. With that, I'll now turn it over to Aaron to review our financial results.
