Languages: Fluent in Turkish, English, and Bulgarian; some knowledge of Russian and Spanish.

Graduate Research (Cornell University, 2000—2007)

Interests: theoretical physics, astrophysics and applied math. In particular: hydrodynamics; electromagnetics; classical and quantum mechanics; programming; development of algorithms.

PhD thesis work: (under the supervision of Prof. Ira Wasserman.)

Precession of pulsars: Modeling the time of arrival residuals of pulsars in terms of precession of a rigid body. Analyzing data using the least squares method and Bayesian inference. Collaboration with Prof. Ira Wasserman (Cornell University) and Prof. Bennett Link (Montana State University). (Publication: Akgün et al. 2006, MNRAS, 365, 653)

Studies of neutron star interiors: The neutron star is modeled in terms of a fluid core (with superconducting and normal fluid regions) and a solid crust (with the possibility of a fluid ocean). Numerical and analytical calculations of the magnetic field and density perturbations. The project employs perturbation theory, magnetohydrodynamics, theory of elasticity, and variational calculus. Collaboration with Prof. Ira Wasserman (Cornell University). (Publication: Akgün & Wasserman, 2007, arXiv:0705.2195v2)

Undergraduate Research and Work Experience (1996—2000)

Quantum Mechanics: Superconductivity in small atomic clusters; investigating various models of the Hamiltonians in quantum mechanics describing small atomic clusters of up to 12 sites. (With Prof. Igor O. Kulik , senior project, Bilkent University, 2000)

Electromagnetics: Calculation of transmitted and reflected fields for an oscillating dipole on top of a surface. (With Dr. Chris M.J. Wijers; research at University of Twente, the Netherlands, 1999)

Optics: Development of software for reflectance and transmittance phenomena from a stack of silicon layers. (With Assistant Prof. Ali Serpengüzel, Bilkent University, 1998—1999)

Numerical Simulation: Simulation of time evolution of wave packets. Exploring ways to eliminate problems encountered in Fast Fourier Transform. Effects of absorbing potentials and filtering at grid boundaries. (Bilkent University, 1999)

Computer System Administration: Maintenance of the undergraduate (Unix/Linux/Windows) computer laboratory of the Faculty of Science. (Part-time job, Bilkent University, 1998—2000)

Teaching Experience & Outreach Activities (Cornell University)

Teaching Assistant (TA) and grader for undergraduate level astronomy classes for 4 academic years. Teaching weekly sections, leading observing sessions at Fuertes Observatory (Cornell University), and conducting experimental labs. Head TA for 2 semesters, coordinating work among the TA’s.

Volunteer for the Astronomy workshop of the Focus for Teens program at Cornell University, for two summers. The workshop aims at motivating high school students to pursue careers in astronomy.
