Jeyachandran joins MarketQuest from Synovate Malaysia where he was previously director of quantitative research.
He has more than 12 years' experience in market research, the first four of which he spent in his home country of India, and the last eight in international postings including Sri Lanka, Egypt and, most recently, Malaysia.
As head of MarketQuest for Synovate UK, Jeyachandran will develop a vision of the business goals to drive growth.
He will work with Synovate's global MarketQuest practice head in creating and developing concepts for clients. Jeyachandran will also participate in developing the UK business.
Michelle Norman, CEO Synovate UK, said: "We are so pleased to have Pranay join us -- his skills and experience from working with clients from around the world will provide us with a valuable global perspective on client needs in this area of research. His transfer from Malaysia to the UK is also a great example of the opportunities within and between markets at Synovate."
