I'm interested in exploring the boundary between computer science and the physical sciences.  In particular, how can astronomers and physicists take advantage of computer science techniques such as artificial intelligence, data mining, computer vision, and game theory.  My current research involves using artificial neural networks and principal component analysis to analyze spectra of proto-planetary disks, the likely sites of planetary formation.  These techniques help me to robustly analyze large amounts of data, discover interesting patterns in the data, and compare and contrast competing physical models.

Introduction to physical principles and their application to astronomy for non-science majors. Emphasis is on comprehension of ideas and principles. Topics include the motions of the sun, moon, stars and planets; properties of the solar system; the stars including giants, dwarfs, pulsars and black holes; nebulae, galaxies and quasars; cosmology and life. The course consists of lecture, discussion and laboratory. Students registering for PHYS 104-01 must also register for a lab, section -51, -61, -62, or -63. Prerequisite: Three years of high school mathematics. NOTE: Students who receive credit for PHYS 104 may not receive credit for PHYS 154.

This course and its continuation PHYS 112 serve as a two-semester introduction to classical physics. Applications are chosen that focus on engineering and the physical sciences. Topics include principles of classical mechanics: vectors, kinematics, particle and rigid body rotational dynamics and statics; conservation laws; and thermodynamics. The course meets three times a week for two consecutive periods consisting of integrated lecture, discussion and laboratory. Prerequisite: A minimum grade of C- in MATH 109 or MATH 113. NOTE: Students who receive credit for PHYS 111 may not receive credit for PHYS 109. Note: Starting with the fall of 2018, PHYS 111 and PHYS 112 have been renumbered to PHYS 211 and PHYS 212 respectively.

Introduction to astronomy for science and engineering majors, with an emphasis on the relevant physical principles. Topics covered include the properties and motions of the Solar system, properties of various stellar objects, nebulae, galaxies, cosmology, and the origin of life in the Universe. Ideas developed in the lecture will be explored and expanded during a separate laboratory section. Students registering for PHYS 154-01 must also register for LAB section, PHYS 154-51. Prerequisite: Math placement at a level of MATH 108 or higher. NOTE: Students who receive credit for PHYS 154 may not receive credit for PHYS 104.
