Kumar attended La Chatelaine Junior College in Chennai. He obtained a bachelor's degree in architecture (BArch) from the School of Architecture and Planning (SAP) at Anna University, Chennai in 2001. Subsequently he received his master's degree, an MDes in Visual Communication, from the Industrial Design Centre (IDC) of IIT Bombay in 2003. He also did his doctoral studies at the IDC, receiving his PhD in 2010.[6]
His areas of interest include graphic design, typography, type design and design research with special focus on Tamil typography (the subject of his doctoral research).
He has also designed a Tamil font named "Parashakti" as a mini project at the IDC, under the guidance of Prof. G. V. Sreekumar, who is one of the few font experts in the country. During his MDes project he wrote and designed a book on Tamil typography, which is the first attempt at bringing such a subject to a Tamil audience. In this book, Kumar also created new Tamil terminology for many typographic terms where English words were used.[7]
Kumar also provided guidance for the designing of the official mascot for the 49th Inter IIT Sports Meet.
Kumar conceptualised the design for Rupee symbol for Indian currency. The symbol is created using the Devanagari letter र 'Ra' and Roman capital letter 'R'. The letters are derived from the word Rupiah in Hindi and Rupees in English, so the symbol is meaningful to both Indians and international users. It also uses the Shirorekha, the horizontal top line which is unique to Indian Devanagari script. The two horizontal lines form an "equals" sign, which also evokes the tri-color Indian flag.[8] Ambika Soni approved the new rupee symbol on 15 July 2010.[9] Udaya Kumar was awarded prize money of for his efforts.
