(NASDAQ:<a class="ticker" href="https://www.benzinga.com/quote/VIVS">VIVS</a>) (the "Company" or "VivoSim"), a provider of next-generation New Approach Methodologies (NAMs) for preclinical safety, today announced the appointment of Dr. Arumugham (Ragoo) Raghunathan, PhD as Vice President of Global Sales. Based in the Greater Boston area, Dr. Raghunathan will lead commercial expansion and secure strategic partnerships with biopharma innovators, established pharmaceutical companies, CROs/CDMOs, and research institutions. His focus will be on delivering VivoSim's liver and gastrointestinal (GI) toxicity solutions for earlier de-risking of drug candidates and clearer feasibility decisions throughout the development process.</p>  <p align="justify">A seasoned executive, Dr. Raghunathan brings extensive experience building trusted, consultative relationships across drug discovery and advanced in vitro biology. He is recognized for bridging scientific and commercial stakeholders, structuring collaborative programs, and guiding customers from pilot studies to scaled deployments—particularly in complex, high-stakes areas such as safety assessment and translational decision-making.</p>  <p align="justify">"Ragoo builds and strengthens relationships through scientific rigor and a relentless emphasis on outcomes," said Tony Lialin, Chief Commercial Officer of VivoSim. "He is the kind of leader customers instantly trust and recognize as a true long-term partner. He understands how discovery, DMPK, and safety teams operate under real-world timelines and constraints. As we accelerate adoption of our liver and GI tox services, Ragoo will be instrumental in helping partners generate clearer, earlier signals—so they can move forward with the best programs with confidence, maximizing both cost and time efficiency."</p>  <p align="justify"><strong>Expanding Customer Impact Across Liver and GI Toxicology</strong></p>  <p align="justify">Under Dr. Raghunathan's leadership, VivoSim will intensify engagement with customers who need stronger human relevance and sharper predictivity in preclinical development, including:</p>  <ul type="disc"><li style="margin-bottom:4pt; text-align:justify;">Discovery and translational teams seeking earlier insight into toxicity liabilities while optimizing efficacy and chemical series</li><li style="margin-bottom:4pt; text-align:justify;">Preclinical safety, toxicology, and DMPK groups looking to improve go/no-go decision quality, candidate selection, and risk management</li><li style="margin-bottom:4pt; text-align:justify;">Biotech startups and emerging pharma aiming to conserve capital by reducing late-stage attrition</li><li style="margin-bottom:4pt; text-align:justify;">Large pharma portfolios requiring scalable, reproducible screening approaches across multiple programs</li><li style="margin-bottom:4pt; text-align:justify;">CROs/CDMOs and strategic partners integrating advanced in vitro safety services into broader development packages</li><li style="margin-bottom:4pt; text-align:justify;">Academic medical centers and research institutes studying mechanism, disease biology, and human-relevant endpoints</li></ul>  <p align="justify">VivoSim's portfolio supports safety assessment programs focused on liver toxicity   including drug-induced liver injury (DILI) risk—and GI toxicity, enabling teams to interrogate potential liabilities with models and readouts designed to better reflect human biology. This is particularly valuable for programs where traditional approaches can obscure or miss risk signals entirely.</p>  <p align="justify">"VivoSim is building exactly what the market has been asking for: practical, human-relevant tools that give development teams a clearer view of tox-compatible candidates earlier in the process," said Dr. Raghunathan<strong>.</strong> "In the Boston area and across the East Coast pharma clusters, there is enormous demand for better prediction of liver and GI liabilities—especially as drug modalities diversify and development timelines compress. I'm excited to help customers translate VivoSim's science into concrete wins: smarter prioritization, fewer late-stage surprises, and faster progress to the clinic."</p>  <p align="justify">In his role, Dr. Raghunathan will also support VivoSim's broader business and strategic initiatives, including key account development, bespoke partnership plans, and customer success programs designed to move engagements from pilot studies to long-term collaborations.</p>  <p align="justify"><strong>About VivoSim Labs</strong><br></br>VivoSim Labs, Inc.
