Career
Venkatachalam is among the first 3 people to do a PhD in Computer Science in India when Doctoral Degree in Computer Science was introduced in India for the first time by Professor Vaidyeswaran Rajaraman at Indian Institute of Technology Kanpur in 1968-69 and he was part of this batch. After obtaining his PhD degree, he joined the Department of Electronics and Communication Engineering of College of Engineering, Guindy, Chennai, India as a faculty member in 1973 and served as the Professor and Head of that department from 1978-1987. During this period, he introduced a number of Bachelor's and Master's courses. In 1978, he founded the Department of Computer Science at College of Engineering, Guindy which is the first Computer Science department among all Engineering Colleges in Tamil Nadu State. He was the Professor and Head of that department also in addition to Electronics and Communications Engineering department until 1987. During this period he introduced Bachelor of Science in Computer Science and Master of Computer Applications (MCA) degrees in Tamil Nadu State. Venkatachalam is the first to introduce industrial training programs for Bachelor's and Master's students by collaborating with well known industries in Tamil Nadu state. He then founded the School of Computer Science and Engineering at College of Engineering, Guindy in 1986, of which he was the first Director and Professor until 1988.
