Electromagnetic Theory I (PH 424), Spring Semester 2026
Role: Course Instructor
About: This is a full-semester, core theory course designed for first-year Master’s students. It is also open to B.Tech and PhD students from various departments as an elective.
Topics Included: Coulomb's law, Gauss's law, electric scalar potential, electrostatic energy, and the applications of Laplace's and Poisson's equations in various coordinate systems. The course also covered Green's functions, the method of images, multipole expansion, electric dipoles, bound charges, and dielectrics. Additionally, we also explored steady currents, the Lorentz force, the Biot-Savart law, magnetic scalar and vector potentials, magnetic dipoles, bound currents, magnetic materials, Faraday's law, electromagnetic waves, retarded potentials and more.

First Year Physics Lab (PH 117), Spring Semester 2025
Role: Teaching Assistant (half-semester)
About: This is a full-semester laboratory course mandatory for all first-year B.Tech students across all departments.
Topics Included: I was in charge of the RLC circuit experiment for half the semester. The students learned how to measure the resonance of an RLC circuit, select appropriate components, and perform error analysis.
