He then worked as Assistant Professor at the Department of CVTS, Sree Chitra Tirunal Institute of Medical Sciences and Technology, Trivandrum, till 2014 where he started VATS Program in 2013. He then joined Amrita Institute of Medical Sciences as a Clinical Associate Professor and in charge of Thoracic and Vascular division, Department of CVTS.

He has been instrumental in setting up the Minimally Invasive and Robotic Thoracic Surgery Division in the Department of Cardiothoracic Surgery at Amrita. He has been trained in minimally invasive thoracic surgery (VATS) at National University Hospital, Singapore and Cedar Sinai Hospital, Los Angeles, USA and Robotic training at the University of Alabama, USA. He has successfully completed more than 300 VATS procedures and more than 100 Robotic Thoracic procedures since inception of the unit. He is an integral part of the Heart and Lung transplant team at Amrita and has been trained at the University of Vienna for Lung transplantation.

His specific areas of interest in Thoracic Surgery include comprehensive lung cancer management, key hole chest surgery ( VATS & Robotics), high risk lung resections and chest wall reconstruction for lung cancer, robotic thymectomy and mediastinal tumour excision, sternal osteomyelitis post cardiac surgery and heart and lung transplantation. His specific areas of interest in Aortic Surgery includes open repair of aortic arch, descending thoracic, thoracoabdominal and infrarenal aortic aneurysms, aortic dissections with Advanced Aortic Surgery training from Cleveland Clinic, USA and endovascular management of aortic disease like TEVAR and EVAR.

His professional achievements include performing the First Robotic Thoracic procedure in Kerala on March 15, 2016. His unit has done 300 major thoracic procedures with 70% of the cases done minimally invasively in 2016 and 2017 which forms the biggest number in the state. He has successfully performed more than 100 robotic thoracic procedures since initiation of the Robotic program. He is a national and international faculty for VATS training programs and has been a training faculty at the prestigious Asian Thoracoscopic Educational Program (ATEP). He has been actively involved in postgraduate training and research specifically in areas of development of large and small diameter vascular graft, indigenous aortic stent grafts and evolving new economical surgical techniques in minimally invasive and Robotic surgery. He has several publications in relevant national and international journals to his credit in addition to numerous talks at various forums and conferences in the state and across the country.
