I have taught a wide range of physics and astronomy courses from the Freshman to the graduate level. I regularly teach courses on thermodynamics, vibrations and waves, optics, electricity & magnetism, modern physics, classical & analytical mechanics, statistical mechanics, and quantum mechanics, in addition to a selected topics course on general relativity, particle physics and cosmology. I have also taught general astronomy courses and an introduction to astrophysics course for physics majors. At the graduate level, I have taught radiative processes, galaxies and cosmology courses. I have experience operating small telescopes, with a suite of research-grade equipment such as spectrographs, filters, and CCD cameras. Over the years, I have supervised physics senior projects with topics ranging from my research interests to quantum computing. Most recent projects were designing a magnetohydrodynamic drive, econophysics, ultra-high energy cosmic rays, design of a vertical-axis wind turbine, the physics of skiing, Alcubierre warpdrive, the physics of a bouncing ball, and designing hands-on demonstrations for modules in high school physics. I have a video lesson as part of the MIT BLOSSOMS project to describe gravity assists to high school students. You can find the video and relevant material here: [https://blossoms.mit.edu/videos/lessons/gravity_assist_or_stealing_planets_angular_momentum_and_getting_away_it](https://blossoms.mit.edu/videos/lessons/gravity_assist_or_stealing_planets_angular_momentum_and_getting_away_it). The lesson is intended to be a teaching duet with the classroom teacher. I wrote every single word in the documentation related to the video, as well as my script. My field of research is observational astrophysics (supermassive black holes and active galactic nuclei: using multi-wavelength spectroscopy, modeling, and machine learning to study accretion physics, feedback, and the co-evolution with the host galaxy). I have published research papers in the top journals in the field of astrophysics: the Astrophysical Journal, the Astronomical Journal, and Astronomy & Astrophysics. I have also refereed for the above-mentioned journals and for the Monthly Notices of the Royal Astronomical Society. I have also served on NASA proposal review panels. Most recently, I have reviewed proposals for the NASA Postdoctoral Program (NPP). I have a certificate from Teaching Science & Technology, Inc. (TSTI; [www.tsti.net](http://www.tsti.net/)) on “Applied Smallsat/Cubesat Engineering Development” in which I gained working knowledge in space mission analysis and design, end-to-end mission architecture, applied space systems engineering, and applied space program management. I have just finished supervising an M. S. project on the design of a cubesat mission to study the dark ages of the Universe from the far side of the Moon. We are in the process of preparing a manuscript for submission to a peer-reviewed journal.
