Academics & Research

Academic activities

  • In 1981, we proudly pioneered the M. Sc., (Medical Physics) course in South Asia in collaboration with Anna University, establishing a legacy of excellence. This postgraduate degree course is offered at the university and has seen over 500 graduates, who are now making significant contributions in India and internationally.
  • Our commitment to education continues, with 30 new students enrolling in the M.Sc., (Medical Physics) course each year. As a testament to our comprehensive approach to medical education, we are actively involved in teaching other programs such as BSc Radiotherapy Technology, B.Sc., Radiology Technology, and B.Sc. Nuclear Medicine Technology.

Research activities

Under the guidance of Dr. N. Vivekanandan, we’ve successfully mentored 12 scholars who have obtained their PhD Degrees, contributing to the ever-evolving field of study. At present 5 students are registered for PhD Degree under his guidance with Anna University. Our current research endeavors showcase our commitment to pushing boundaries. Ongoing study involves the 3D printing technology, Deformed Dose Accumulation, Portal dosimetry, FIF planning, Patient specific QA and Enhanced Leaf modeling.

Legacy

  • The department began in November 1957 under Dr. K.S. Chandrasekar, Ph.D., who served as Head of the Department and laid the foundation for its academic legacy.
  • In August 1958, Dr. A.V. Lakshmanan, Ph.D. joined the department and became Head in April 1962. His dedication and leadership shaped the department until his retirement in August 2006. He retired as Director (Administration) and continued as an Adviser until 2022.
  • In April 1965, Dr. I.S. Balakrishnan, Ph.D. joined the institute and played a pivotal role until his retirement in April 2007, culminating in the position of Chairman, Physical Sciences.
  • In July 1993, Dr. N. Vivekanandan, Ph.D. joined the institute. Since May 2007, he has served as Professor and Head of the Department, leading with passion and expertise.
  • The dedication and contributions of these visionary leaders have shaped the department into a hub of academic excellence. The department continues to strive for innovation, research, and educational advancement.
