PH5210 Independent Study Rangeet Bhattacharyya

This course requires approval from the respective instructor for enrolment

This is a course offered to the RS (Ph.D) students in their first year. The student can perform an independent study under a DPS faculty (including his supervisor). The evaluation at the end of the semester will be done by a committee of three instructors. The course should be initiated for each individual student by a mutual consent between the student and the faculty.

The regulations are:

  1. RS students can take a reading course (as 'Independent Study') only if the core and elective courses offered in their
    curriculum do not cover the topics/subjects of the reading course.

  2. Regarding the final evaluation of the student a written document should be submitted to DoAA. (Final evaluation can be regular or take home exam or presentation in front of the course instructor and another faculty member. In that case case the hard copy of the presentation
    can be considered as a written document).

  3. Faculty interested to offer a full semester 'Independent Study' for Research Scholars , must submit the following to the Syllabus Coordinator and Chair before the courses go online each semester: a) Title, and b) Syllabus (short, 5-6 lines,). Without a syllabus nothing exists and it will not be practically possible to consider any course for this option.

  4. There is NO LIMIT RS students who may opt for One Independent Study.

  5. Students NEED to find the available syllabus from the list below, contact the instructor, and with his permission register for the Independent Study. Private communications with a prospective instructor will not be counted as registration.

  6. Before the final deadline, the student must submit the Student's Name, Instructor's Name, Title, Syllabus, & Signature of the Instructor in a piece of paper to the Syllabus Coordinator of DPS.

  • Introduction to Biophotonics \\
    Prerequisites: Basic knowledge of Electromagnetic theory, Optics \\
    Biophotonics is the application of photonic science and technology to
    life sciences. It is a rapidly emerging area with a wide range of applications in clinical medicine and biology. Early detection of cancer, ultrahigh resolution optical microscopy, minimally invasive imaging for tissue function monitoring, therapeutic applications, measuring genetic patterns, identifying pathogens are all examples of biophotonic applications. Biophotonics being a forefront area of interdisciplinary research, requires fundamental understanding of light matter interaction and imaging; this course will be an introduction to students interested in such interdisciplinary research.\\
