Thanks, Steve and good afternoon, everyone. Let me start by reflecting on the fiscal year we just wrapped up, which was a busy and transformative period for us. We're a much different organization than we were one year ago. We've evolved in the way we define ourselves, how we bring the value of our platform technology to customers and future patients, and ultimately, how we aim to create sustainable and growing value for all of our stakeholders. Organovo is a biotech company, pioneering the remarkable ability to 3D bioprint tissues with human functionality. We are harnessing our platform to potentially treat a range of pediatric and adult liver diseases in the medium term. And today, we are successfully funding a growing portion of this therapeutic mission by providing our clients access to our technology platform. Our primary goal is to develop our own novel therapeutics and to treat a group of life-threatening rare diseases for which there are few current treatment options other than organ transplantation. Our healthy NovoTissues, liver tissue product can potentially address a broad range of target indications, offering important synergies in terms of manufacturing, R&D, and de-risking the development process. Our objective is to simultaneously advance multiple IND-track research programs in critical unmet disease areas, commencing with Alpha-1-antitrypsin deficiency or A1AT. We believe this indication alone represents the opportunity to generate peak revenues approaching $1 billion. Adding in other liver diseases that typically end in the common need for liver transplant, such as single mutation inborn areas of metabolism, urea cycle deficiencies, and acute-on-chronic liver failure, a total peak revenue target exceeding $4 billion may be achievable for our NovoTissues platform, and this is just in liver disease. Because each indication represents a serious unmet medical need, we have the opportunity to work closely with the FDA and other regulatory bodies to streamline our path through development into the market. And of note, we should be able to capture various attractive incentives along the way that the FDA provides to induce research in these areas. Using our same liver platform today, we are working to create near term value by allowing our customers to access our disease modeling capabilities in order to facilitate their own discovery and development programs. Our foundational ability to characterize specialized human cells and build robust functional human tissues has led us to the opportunity to develop custom disease models that mimic conditions of non-alcoholic fatty liver disease, NAFLD; and non-alcoholic steatohepatitis, NASH. Given the rapidly growing number of NASH development programs, we will continue to work with early adopter clients to explore a range of conditions for which our tissue platform might add value to their internal research programs. Now, I'd like to outline our goals for fiscal 2019, beginning with our therapeutics program. We've already taken several big steps in fiscal 2018 to build out our IND track therapeutics programs. In our first indication, A1AT, we implanted our liver patches into disease mice, showing a high degree of functionality and a significant reduction in disease features, all the way through 125 days. This timeframe, if translatable to humans, would offer a significant and perhaps life-saving benefit to patients awaiting full transplant, where supply is severely limited. We also reached our first regulatory milestone for the A1AT program, with the FDA granting orphan status for our NovoTissues treatment of that disease. As I look out over the next 12 months, we will complete the necessary steps to begin IND-enabling studies for this program in fiscal 2019. In addition, we hope to work closely with the FDA and key advisors to finalize the confirmatory animal studies and scientific validation path we’ll need to follow for a successful pre-IND meeting for this first indication. We also began new animal model studies in a second therapeutic indication within the category of inborn areas of metabolism. This second disease known as type 1 tyrosinemia caused by the deficiency of the FAH enzyme frequently causes severe liver damage and commonly requires the patient to receive a new liver at an early age. As you may have read in our recent press release, we presented preliminary proof-of-principle data at an industry conference a few weeks ago showing improved survival rates as well as good retention and evidence of human functionality of our tissues in established animal models for this condition. As we look ahead to the rest of fiscal 2019, we’ll work to validate this disease area using the same or similar tissue constructs as are being studied in A1AT. Much like our first program, we’ll pursue orphan designation for this indication with the FDA with the goal of ending our current fiscal year with two liver therapeutic tissue programs on track for IND submissions in 2020. You can expect us to present important updates of these revolutionary therapeutics programs at major industry and scientific conferences throughout the year. As I have mentioned, while we're advancing our tissue platform in a broad range of in-vivo animal studies, we're also making great strides to create immediate value by providing access to our technology platform for partners, collaborators, and clients. The stream of revenues generated through this access provides scientific validation and financial support for our therapeutics pathway and also has the potential to generate new pipeline ideas and capabilities. A key building block of our platform is primary human cells, provided by our wholly owned subsidiary, Samsara, which has quickly become a cornerstone of our revenue growth. Samsara capitalizes on our ability to procure and characterize high quality human cells that are in demand for our clients’ research programs, while also supporting the development of our liver disease models in our therapeutic tissues program. This business more than tripled its contribution to our total revenue during fiscal 2018, and we continue to expect robust uptake of our cell based products this year. Our recently announced multi-year agreement with Lonza Bioscience Solutions, one of the world's leading suppliers to biopharma and specialty ingredient markets represents Samsara’s largest contract to date and further supports a healthy growth trajectory. Importantly, Samsara’s work with customers often serves as a key indicator of market trends and the close relations between Samsara and its clients can lead to larger partnering relationship spanning our full platform capabilities. Because of our ability to create a disease testing capability which we believe will be translatable, namely predictive of real human outcomes, we have the potential to provide patient-on-a-plate results in a fraction of the time and cost of conducting human clinical trials. As a result, we believe our clients will turn to us to provide solutions across the R&D spectrum from novel drug targeting research to comprehensive lead candidate profiling to teasing out competitive advantage aspects of drugs already in the clinic. Similar to our commitment to communicate progress on our therapeutics program, we will continue to participate in venues such as AASLD, The Liver Meeting; EASL, The International Liver Congress; and the NASH Summit, where our platform advances in NASH have been generating considerable recognition. Finally, as we advance the functionality of our tissue platform with eyes on the clinic, we will continue to build out our global IP portfolio, which today includes over 100 patents and pending applications. In closing, fiscal 2019 is shaping up to be an exciting year with a number of important milestones in sight for both our therapeutics program and our tissue platform operations. We have an outstanding team at Organovo, bolstered by a group of collaborators and partners with the ability to transform liver health. As such, we’ll continue to generate new horizons and pipeline opportunities based on our growing body of knowledge around 3D bio-printing functional tissues. As always, I look forward to updating you regularly on our progress in the months ahead. With that, I'll turn it over to Craig for a more complete financial review.
