Prof. Subhash C. Arya addressing on the occassion of the Teacher's Day in the Department of ECE, NEHU Shillong on 5th September 2024

 

Good Morning to All,

 On this wonderful occasion of Teacher’s Day, I extend my heartfelt greetings to all our students, faculty members, Ph.D. scholars, technical and office staff, and our respected colleagues from the Department of Basic Sciences and Social Sciences. Today is a day to reflect on the remarkable role teachers play in shaping the future and to celebrate the journey of learning and teaching that we are all a part of.

 

As the Head of the Department of Electronics and Communication Engineering, I am glad to share our collective achievements over the past year. Let me take this opportunity to share some significant milestones.

 This year, our B.Tech (ECE) program achieved a pass percentage of 86.95%, with 40 students graduating out of 46 who appeared. Similarly, in the M.Tech (ECE) program, we recorded a pass percentage of 87.5%, with 7 students graduating out of 8. I also convey that 2 Ph.D. degrees were awarded this year, adding to our department's growing list of scholarly achievements. A total of 18 peer-reviewed journal articles have been published by the scholars and faculty members of the department.

 

Our department's success is not only reflected in our student’s academic performance but also the outstanding work of our faculty members. Out of our 11 faculty members, 6 have secured sponsored projects worth close to ₹1 crore (₹98.20 lakhs), either as Principal Investigators or Co-Investigators. Additionally, more than 20 Ph.D. research scholars are actively engaged in cutting-edge research under the supervision of our faculty. I am pleased to mention that, under the leadership of Prof. Rupaban Subadar, we have established a fully state-of-the-art 5G Training Lab, positioning our department at the forefront of 5G technology and beyond.

 One of our department’s proudest achievements this year is the full implementation of the NEP-2020 curriculum across our B.Tech, M.Tech, and Ph.D. programs. This forward-looking approach ensures that our students are equipped with the knowledge and skills they need to thrive in today’s rapidly evolving technology landscape.

 As we celebrate these accomplishments, it is also important to address some of the challenges that lie ahead. One area of concern is the gradual decline in the intake of M.Tech and Ph.D. students, which we need to address with renewed vigor. Additionally, graduate placements have not been as strong as we would like, and we must work collectively to enhance the employability of our graduates. Another pressing issue is the increase in unfair practices during exams and a decline in student attendance in physical classes. It is concerning to see some students disengaged from the pursuit of knowledge, which may be attributed to growing academic fatigue and depression.

 However, despite these challenges, I am optimistic about the future. I encourage our B.Tech, M.Tech, and Ph.D. students to take advantage of the opportunities available through the India Semiconductor Mission (ISM), particularly through our Chip-to-Startup (C2S) project, which is being spearheaded by Dr. Pankaj Sarkar, Dr. S. K. Dutta, and Dr. Nipanka Bora. This project will enable our department to contribute significantly to the semiconductor industry, particularly in chip design, and produce a substantial workforce to meet the country’s growing needs in this sector.

 

When collecting feedback from the B.Tech (ECE) Batch 2020-2024, I noticed that 40% of students rated the program as "good," 20% as "very good," 30% as "average," and 5% as "poor" in comparison to other institutions. While this feedback is insightful, I am pleased to inform you that we have revised the B.Tech (ECE) syllabus, and I am confident that the changes will lead to even better outcomes in the future.

 In conclusion, as we celebrate Teacher’s Day, let us recommit ourselves to excellence in teaching, research, and student engagement. Our department has achieved so much, and with your continued dedication and hard work, I do not doubt that we will rise even higher in the coming years. I thank each and every one of you—faculty, students, staff, and scholars—for your unwavering contributions to the growth of our department. Together, let us continue to pursue our shared goals, both for our department and for our university.

 Thank you, and once again, I wish you all a very Happy Teacher’s Day!
