Vasu Ranganathan, Partner

“I've learned that you shouldn't go through life with a catcher's mitt on both hands; you need to be able to throw something back” (Maya Angelou). Of course, not all of us are expert players, but you don’t need to be an expert to enjoy the game – and being able to throw something back enriches the experience.

Vasu Ranganathan is a founding partner of ArborSys. She has over 25 years of experience in leading business and technology programs in commercial and government sectors. Over the past 15 years, she has held leadership positions in global, mid-size, and small consulting organizations supporting Life Sciences, Financial, Publishing, and Insurance sectors. As a partner at ArborSys, she works with the senior team to develop the ArborSys business model and lead delivery in business and technology strategic implementations for clients seeking to improve their performance.

Shailesh Shah Partner

Shailesh Shah, Partner

In a fast-paced, politically charged environment with tight schedules and shrinking budgets, knowing technology isn’t enough. You need a partner with deep domain expertise, application of best practices, and a team willing and capable to take ownership to meet deadlines. I tell my clients we need to stay out of Mo Town, where everyone wants Mo time, Mo people, and Mo money.

Shailesh has 20+ years of experience in the software development industry as a developer, technical lead, technical project manager, and solution architect. He has a wealth of knowledge in highly regulated industries like pharmaceuticals and life sciences. He has extensive experience in working for global clients while managing onshore, offshore and/or blended teams. Shailesh holds a BS in Computer Science from MS University (India) and an MS in Information Systems from New Jersey Institute of Technology.

Angela Horowitz, Practice Director Structured Content Management

Angela Horowitz, Partner

Angela has over 15 years of experience in the biotech and pharmaceutical industry as a medical writer and business analyst. She has an excellent understanding of the clinical development lifecycle from study planning through post-marketing.

Angela has worked on various projects ranging from regulatory submissions to business and IT process improvement initiatives. More recently, she has become actively engaged in the structured content management (SCM) domain, helping clients define their SCM strategy and roadmap, develop their information architecture, evaluate SCM vendors, and run a proof-of-concept or full implementation of the selected SCM tool. “Don’t boil the ocean” has become one of her favorite sayings. In the world of SCM, you need to strategically boil water one bucket at a time in order to reach your goal. Prior to joining ArborSys, Angela worked at Genzyme Corporation and Sanofi. She holds a BA in English and Biology from Colgate University, and an MPH from Nova Southeastern University.
