Research Assistant

(September 2003 – present)

(September 2002–July 2007)


  • Theoretical investigations of particle acceleration and time-dependent radiation transfer in relativistic jets using an internal shock model. This included taking into account the in homogeneity in the photon density throughout the accelerated (emission) region, the analytical evaluation of the average photon escape timescale for a cylindrical emission region and numerically obtaining a simplified expression for the synchrotron power from a power-law distribution of electrons.

  • In-depth theoretical analysis of the BL Lac object 3C~66A on the basis of the data obtained from an international multi wavelength campaign in 2003/2004.

  • Contributed to the initial data collection and analysis of the preliminary results of 3C~66A.

  • Participated in 5 1-week observing runs at the Kitt Peak MDM observatory and contributed to the primary reduction of data from those runs.

  • Designed and completed a short-term project to study the optical warp of a spiral galaxy NGC 5529 in the I band using the 0.25 meter Great Ohio Telescope (GOT) of Ohio University.


  • Significant effort in the supervision of two undergraduate students for their research project in astrophysics

  • Lab instructor and recitation sessions for various undergraduate classes

    • Physics 250 Series: General Physics, calculus based (Classical mechanics, Thermodynamics, and Electricity & Magnetism)

    • Physics 200 Series: Introductory Physics, algebra based (Classical mechanics, Thermodynamics and Electricity & Magnetism)

    • Astro 100: General Introduction to Astronomy (sun, stars and galaxies, interstellar matter, blackholes, "Big Bang" theory, evolution of the universe

  • Conducted undergraduate student help sessions and graded physics and astronomy undergraduate courses for Physics 250 & 200 series and Astro 100.

  • Substitute lecturing for a Physics 251 (Classical mechanics) and Astro 100 (sun) class

  • Grading of graduate level Quantum mechanics for a class of 10 students
