Personal
  • Date of birth: 28 July, 1985
  • Place of birth: Dortmund, Germany
  • Citizenship: Egyptian
  • Visa status: F-1 student visa
Research Interests

Computer Vision, Graphics, Stochastic Processes, and Machine Learning.
My research can be broadly categorized as using statistical and information-theoretic methods to solve problems in computer vision, graphics, and dynamical systems. Problems I have worked on include, speech interfaces for robots, street sign identification, object recognition, alignment of curves, joint alignment and clustering of images, and image-based rendering.

Research Experience
  • Research Assistant, Computer Vision Laboratory, UMass (Jun 2004 - present)
    Advisors: Allen Hanson and Erik Learned-Miller. Projects include:
    • Plankton Classification: An ongoing collaborative effort between UMass, Bigelow Labs for Ocean Sciences and Louisiana State University on classifying low resolution images of plankton. Research issues include novel segmentation algorithms, methods for automatically learning informative image patches, and frameworks that combine the information in image patches and [global] features computed over the entire image.
    • Event-related potential signal alignment and classification: An ongoing collaborative effort between the Computer Science and Psychology departments on classifying and aligning ERP signals. The joint alignment process allows us to recover the underlying ERP signals and consequently better account for latency variations.
    • Sign Recognition: Developed a sign identification module for a sign detection/recognition system that was intended to be used by the visually impaired.

  • Research Assistant, Laboratory for Perceptual Robotics, UMass (Dec 2002 - May 2004)
    Advisor: Andrew Fagg. Projects included:
    • Speech Interfaces for Robots: Developed a system that parsed voice commands and stored them in the robots local memory and allowed robot "responses" to be output through a speaker. This work was the basis for a system that allows verbal communication with the robot.
    • Color Recognition: Developed a probabilistic object recognition system based on color. Using the speech interface, this allowed objects of interest to be specified to the robot via voice commands that contained the color of the object.
    • Mini-Ubots: Built 9 mini robots for a multi-robot coordination and control project.
Teaching Experience
  • Guest Lecturer, Department of Computer Science, UMass Amherst (April 2006)
    Course: Computer Vision. Taught three lectures covering Support Vector Machines, Principal Components Analysis and Independent Components Analysis and their applications to plankton classification and face detection/recognition. Prepared lectures and homework assignments.

  • Teaching Assistant, Department of Mathematics, UMass Amherst (Sep 2003 - May 2004)
    Course: Calculus. One of two TA's for a lecture of 290 students. Held office hours and exam review sessions, graded quizzes, and proctored exams.

  • Volunteer Tutor, Department of Mathematics, UMass Amherst (Sep 2003 - May 2005)
    Helped students seeking assistance in Math courses and exams. Assisted students taking Calculus and Differential Equations courses as well as preparing for the GRE (Quantitative section) and the Nursing major math proficiency test.
Work Experience
  • Part-time Intern, IAVO Research, Amherst MA (Summer 2005)
    Implemented the SIFT interest point operator algorithm and developed software for computing the relative camera orientation between two aerial images (using SIFT matches).
  • Resident Assistant, Washington Hall, Residence Life (Sep 2003 - May 2004)
    Supervised a floor of 30 residents in a building of 550 students. Created a safe and healthy environment, organized social events and resolved conflict.
