DEPARTMENT OF PHYSICS

 


Dr. D. Nagaraja, MSc, Mphill, Ph.D
Professor and HOD

 

 

VISION
Instill the spirit of Scientific Curiosity in both the teacher and the taught

 

MISSION
  • A science club with multi varied activities
  • Institute an extracurricular demonstration room where the students can build and have hands on experience on topics/ experiments not included in the syllabus
  • Bring Monthly bulletin on recent developments in SCIENCE & TECHNOLOGY and Organize workshop/conferences on science related topics

 

The Physics department has a staff of 7 members of which 3 members have more than 25 years of teaching experience. There are TWO well-equipped Physics laboratories. Students are given individual attention in the lab classes. The results in both theory and practical examinations have been consistently good. Several workshops/conferences sponsored by Indian Academy of Sciences, KSCST and Rajya Vokkaligara Sangha, are constantly organized.


Infrastructure: Engineering Physics laboratory has Two well equipped labs with basic infrastructure and instruments. It has main laboratory = 115.15 m2, optics laboratory = 27.85. m2, and store room= 24.14 m2.

Research Projects in the department:

Dr. D. Nagaraja had received a project grant of Rs. 20 Lakhs from Government of Karnataka under VGST scheme KFIST-L1 for a period of 2 years from 2017 to 2019.

R&D activities:

The department has well established research center with 5 VTU recognized guides and major equipments like UV-VIS spectrometer and Shock wave tube. Faculty are actively involved in research on varied fields which includes photophysical properties of heterocyclic compounds, fluorescence spectroscopy, polymers, composite materials and liquid crystals, and 5 of them have obtained Ph.D from VTU. 3 students are pursuing their research in the department. Project proposals are submitted to various funding agencies like VGST, AICTE, SERB, DRDO etc. Department has nearly 90 research publications in national and international journals. The faculty have attended many refresher courses/FDPs/workshops and presented their research work in many national and international conferences.

 

Dr. D. Nagaraja has presented his research work in 8th Global Conference on Materials Science and Engineering (CMSE2019), held at Sanya, CHINA from 12-11-2019 to 15-11-2019

Dr. Geethanjali HS has presented her research paper in 14th International Conference on “Methods and Applications of Fluorescence (MAF14)”, from 13th – 16th Sep 2015 held at Wurzburg, GERMANY

Additional and technical support/facilities provided to the students

* During the COVID-19 emergency, our faculties have taken various measures to reach students using modern technical tools such as Zoom class, Google drive links, YouTube videos, Google classroom etc. The link related e-contents is provided separately for the benefit of stakeholders

* Our Faculty Dr.BV Chaluvaraju and Dr. UP Raghavendra have encouraged students to take up mini projects like conducting polymer composites and nano materials and assisted 8th Sem students in their final year project.
