Research Experience Back
MIT Research Laboratory of Electronics, Quantum and Optical Communications Group, Cambridge, MA (June 2001--present)
Classical and Quantum Optical Imaging:
Ph.D. dissertation focuses on developing a unifying theory for classical and quantum imaging through the study of coherence theory for phase-sensitive light.
  • Proposed a new optical coherence tomography (OCT) method---named Phase-Conjugate OCT---that utilizes classical phase-sensitive light together with phase conjugation to achieve the axial resolution and even-order dispersion cancellation of Quantum OCT, with a signal-to-noise ratio that can be comparable to that of conventional OCT techniques.
  • Developed a unified treatment of ghost imaging with classical and quantum Gaussian-state sources, which unambiguously identifies the features of ghost imaging that are strictly quantum mechanical.
  • Developed free space coherence propagation theory for (classical and quantum) phase-sensitive Gaus\-sian-Schell model fields.
Near-Field Atmospheric Optical Communications
Master's thesis focused on theoretical performance analysis of near-field point-to-point atmospheric communication links in the presence of turbulence.
  • Obtained error probability bounds for {\em uncoded} transmission, when pulse-position modulation or on-off keying in combination with a coherent or direct detection receiver is employed.
  • Derived bounds on the ergodic capacity for coded transmission over fast-fading channels utilizing either local oscillator shot-noise dominated coherent detection (Gaussian noise statistics) or shot-noise limited direct detection (Poisson noise statistics).
Diversity in Atmospheric Optical Communications
Experimental project to establish a high data rate, far-field atmospheric optical communication test bed, utilizing spatial diversity at the receiver and optical amplification prior to detection.
  • Contributed to the derivation of an accurate channel model and compared the theoretical bit error rate predictions with experimental measurements. Assisted in experimental measurements of atmospheric fading in different weather conditions and over multiple wavelengths, to verify the accuracy of employed statistical turbulence models.
  • Participated in experimental setup of transmitter and receiver for the test bed.
MIT Laboratory of Information Decision Systems, Cambridge, MA (January 2000--June 2001)
Target Parameter Estimation
As an undergraduate researcher, contributed to a project on target pose estimation using imaging data.
  • Established analytic performance measures for target pose estimators using simplified block-structured targets and imaging-sensor noise models.
  • Derived and numerically evaluated Fisher Information for articulation angle estimation, when a uniform temperature target is imaged from a fixed elevation.
  • Extended Fisher Information analysis to targets that contain cold or hot spots. Furthered analytic understanding of information contribution from different features of target objects.
MIT Media Lab, Hyperinstrument Group, Cambridge, MA (December 1998--September 1999)
"Toy Symphony" Project
As an undergraduate researcher, contributed to project aimed at creating a communication network between individual toy instruments to create a virtual symphony. Participated in designing sensor-placement in individual units. Assisted in implementation of simple wireless networking protocols between units to allow synchronization and interaction.
Scientific and Technical Research Council of Turkey--Information Technologies and Electronics Research Institute, Ankara, Turkey (June 1998-September 1998)
Speech Processing Software Development
As a summer intern, designed graphical user interface in Visual C++ for a commercial speech analysis and processing tool. Learned basic concepts of encoding and decoding speech as well as voice recognition.
