PhD SRM Institute of Science and Technology in collaboration with NOVA school of science and technology, Portugal. Topics: Atomic Molecular and Laser physics, Nuclear and particle physics, Waves and optics.

I am a **theoretical and experimental physicist**. My main research interest is First-principles investigation of halide based lead-free double perovskites for green energy and spintronics applications.

Apart from research, I am also highly motivated to teach undergraduate and post-graduate levels. My teaching methodologies involve collective engagement of students in problem-based activities, improved time utilization, and critical thinking skills. I motivate students to work as a team to solve a series of questions leading to development of a concept or principle

**Atomic, Molecular and Laser Physics **

My goal is always to guide the student in learning the subject by teaching them through simple examples and then practicing advanced level problems suited for national and international level competitive exams. The state of art is that of introducing concepts, designing, and refining methods, and practicing them repeatedly using basic concepts.

My course on Atomic, Molecular and Laser Physics**, **helps students to get equipped with the necessary tools that will be used in Classical Mechanics, Quantum Mechanics, and Electromagnetic theory.

** ****I encourage students to solve problems by understanding the basic concepts and applying the first principle to them.**

- Bohr Somerfield theory and Hydrogen atom
- Fine structure of hydrogen atom
- L-S and J-J coupling
- X-ray spectra and broadening of spectral lines
- Rotational, Vibrational and electronic spectroscopy, Raman effect, Frak-condon principle
- Laser physics

**Nuclear and particle Physics **

Broadly, I cover the following topics during my course

- Rutherford scattering, Basic properties nuclear forces.
- Liquid drop model, Shell model, and Collective model
- Nuclear reaction, Q value equation
- Radioactive decay, Fission and Fusion reaction, Tunnelling of alpha particle.
- Fundamental forces, Classification of sub-atomic particles, Elementary quantum number, Conservation laws associated with fundamental interaction.
- Quark model.

**Waves and optics**

Broadly, I cover the following topics during my course

- Ray Optics
- Thick lens, thin lens, and lens combinations
- Wave Optics
- Superposition Principle
- Interference of light
- Diffraction
- Polarization

I believe in classroom climate that fosters thoughtful and respectful consideration of alternative viewpoints and ideas
