Senthil Murugan is a Director at Pfizer. Colleagues describe them as "I reported to Senthil for about 7 years. I admire him both personally and professionally. He’s an honest, considerate, hard-working and intelligent person. Senthil approaches promotional impact measurement and budget optimization with a vast toolkit of statistical methods. He enjoys challenges and views them as opportunities to develop himself and his team. Not only does he research new statistical approaches, he also seeks to under business concepts like new promotional channels to ensure that the team captures the data and measures the channel impact accurately. While somewhat complex statistical approaches can be warranted, he also realizes the importance of delivering actionable and understandable results. He carefully balances statistical rigor with business acumen and considers how historical measurements need to inform future planning and possibly within existing structures or tools. Senthil has instructed me in many statistical techniques and how to apply them to my projects. He is patient and capable of communicating difficult concepts using visual depictions and simplified examples to his fellow data scientists and also business customers. Senthil is clearly capable of communicating and working with various types of individuals like senior marketing leadership, third party vendors, consulting companies, internal IT and finance departments and so on. Over the years, the team’s size and structure changed and Senthil continued to ensure that customers’ needs and deliverables were met. This success was largely due to Senthil’s ability to identify priority projects, push back on requests not tied to department’s objectives and weeding out “nice to have” requests from those with actionable business questions." and "I have had the privilege of working alongside Senthil for over 15 years at Merck, and without reservation, I wholeheartedly recommend him for any data science senior-level position.

Even amidst the most demanding circumstances, Senthil adeptly guided our team through challenges, easily managing communications, refining methodologies, reprioritizing tasks, and swiftly adapting to evolving needs. His leadership style is exemplary, and I am confident he would make a stellar addition to any data science organization. As a statistical analyst, Senthil is unparalleled in his wealth of knowledge and expertise in statistical modeling techniques and methodologies. When presented with a business question, he swiftly assesses the data landscape, discerning what is and what is not feasible.
