Thank you, David. Good afternoon, everyone. Thank you for joining Certara's first quarter earnings call. John and I will begin with prepared remarks, and then we will take your questions. We are pleased with our start to the year, delivering financial results consistent with our expectations, driven by strong commercial execution across both software and services. We finished the first quarter with revenue of $106 million representing 10% reported growth versus the first quarter of 2024. Certara’s first quarter bookings of $118.2 million represented 12% reported growth versus the prior year period, driven by software bookings growth of 23% and services bookings growth of 7%. Additionally, we continue to see good performance from Chemaxon, which contributed $5.9 million of revenue and $4.9 million of bookings in the quarter. The current market has both continued headwinds that we've been managing over the past couple of years as well as some new and exciting tailwinds for Certara. Continued headwinds include the downstream effects of IRA price controls, an erratic capital raising environment for biotechs and a potential for new trade and healthcare policies from the current administration. Tailwinds include the recent FDA announcement about phasing out animal testing, a general willingness to expand the use of modeling in pharmaceutical development and the increasing spending on artificial intelligence solutions among our customers. In the long run, we expect most of the headwinds to resolve, while the tailwinds are likely to remain in Certara's favor. With that in mind, we will continue to execute our strategic investment plan focusing on the integration of AI into our software solutions, building a more integrated software platform, increasing our investment in bio stimulation model development and expanding our solutions into the earlier stages of drug development. Certara’s value proposition is multifaceted. We accelerate decision making to drive more cost effective development by making better use of scientific modeling and data analysis. Over the past several years, we've invested to build Certara into the leading partner in biosimulation by creating new software products and features, building a robust commercial infrastructure capable of selling to the large number of customers in our industry and executing strategic M&A to expand our capabilities. The FDA's recent announcement of a plan to phase out animal testing requirements for monoclonal antibodies and other drugs increases the relevance of Certara’s capabilities. This new direction follows a framework outlined by Congress and the FDA Modernization Act 2.0 that was passed in late 2022 and aims to develop a clear regulatory pathway to streamline the drug development process, including leveraging computer modeling and artificial intelligence to predict a drug's behavior. Certara has created a biosimulation solution called Non-Animal Navigator for preclinical monoclonal antibody development, which uses our Simcyp simulator and our QSP modeling group. The solution also leverages the extensive experiences of our services team in creating first in human study designs. In the weeks following the announcement, we have seen significant inbound interest from customers who would like to understand the role Certara can play in their preclinical development. Just last week, we hosted an online webinar with over 400 attendees outlining our approach to helping customers navigate alternatives to animal testing. We believe new regulatory initiatives at the FDA, including phasing out animal testing, are long term tailwinds for the adoption of modeling and simulation tools across drug development phases. Now turning to our commercial performance in the quarter. In software, we continue to see healthy bookings performance from our Tier 1 and Tier 3 customers, with high renewal rates and a modest upsell contributing to growth. We've also begun to realize some cross selling benefits as we integrate Chemaxon into our broader commercial organization, leading to another strong quarter with $5.9 million of revenue. In services, we observed stable demand across both biosimulation services and regulatory services. In biosimulation services, we continue to see some softness in the Tier 1 customer base, which was offset by solid growth across Tiers 2 and 3. In Regulatory Services, we saw revenue bookings growth on a year over year basis with strong contribution across all three customer tiers. Heading into the second quarter, we are encouraged by the underlying demand from customers and are confident in our ability to meet our commercial goals at this point in the year. In addition to strong commercial performance, our R&D teams continue to make progress on the software development front. On April 1, we announced the 24th version of our Simcyp Simulator, which was the culmination of months of hard work from our team paired with valuable feedback and insights from over 30 consortium members. This year, updates were focused on numerous new features, including an expanded library for drug drug interactions, additions to our biopharmaceutical and virtual bioequivalence modules, enhancements to support modeling of special populations and an improved user interface. To date, Simcyp has supported over 120 FDA approved novel drug applications and over 300 label claims in addition to being granted numerous clinical trial waivers. As we expand the breadth and capability of our software platform, we look to stay active and in front of our customers. We are excited to host the second annual Certainty Conference in Philadelphia beginning tomorrow. Last year's conference was a success and we are thrilled to host over 300 clients showcasing the advancements we've made in model informed drug development. Certainty has become an opportune time to showcase our capabilities in the preclinical area as our customers look for alternatives to animal testing and there will be several presentations elaborating on how Certara can help drug developers implement new approach methodologies such as PBPK and QSP. During the quarter, we also had the pleasure of welcoming new leadership to our services group. We're pleased to welcome Dr. Adrian McKemey as President of our Drug Development Solutions business. Adrian joined Certara with over 25 years of industry experience, having led business transformation, portfolio management and R&D initiatives for a wide variety of clients in the biopharma industry. As part of a planned leadership transition, Patrick Smith has moved into a new role as Senior Vice President of Translational Sciences. Patrick will continue to be a key member of our services group, focusing on Certara’s scientific growth and innovation. Before wrapping up, I wanted to provide an update on some recent announcements. On April 14, we announced $100 million share repurchase authorization and provided an update on the strategic review of our regulatory business. The Board's decision to authorize a share repurchase allows us to have more flexibility with the management of our capital to drive value for shareholders. This authorization from the Board reflects their support and confidence in our investment in biosimilation, including AI and in the strategic decisions we have made to drive long term growth for the company. However, our primary use of capital remains the same as it has been since we became public and we will continue to be active in looking at M&A opportunities and making organic strategic investments to drive long term sustainable growth. Also, as we announced, we have been proceeding with our review of the regulatory business and have received interest from external parties, though we do not have more to announce at this time. To close, we are pleased with our first quarter results and we are excited by the evolving opportunities at the company. Our team is executing against our commercial plan, driving solid operational performance in light of more muted end markets. Our R&D initiatives are progressing nicely and we are on track to launch several new products later this year. The secular tailwinds for biosimulation continue to drive adoption and we are excited to play a role in the evolution of drug development towards new methods and approaches. With that, I'd like now to hand things over to John Gallagher to discuss our financial results in more detail.
