It turns out getting involved in computational photography also gets you involved in regular photography.

Light Painting! Light Painting! Light Painting!

As of January 2014, I am starting my first full-time job at Dropbox. Before that, I was a doctoral student at Stanford University, advised by Marc Levoy, doing various things related to computational photography. Even before that, I completed at MIT my undergraduate degrees in theoretical mathematics and in computer science (advised by Tomasz Mrowka and Scott Cyphers, respectively) and an M. Eng degree in computer science (advised by Fredo Durand, with thesis on multi-channel coded aperture).

News

Jan 28, 2014: I am now working at Dropbox. I work in image processing, computer vision and machine learning. My work email is [first name]@dropbox.com.

Dec 5, 2013: My dissertation is approved! As of December 5, I have concluded my Ph.D. program!

Research

My research interest lies in computational photography, computer vision, and graphics. In particular, I love the mathematical aspects of imaging and image processing. I have recently been interested in the mobile and real-time application of computational photography. I have worked on image editing, especially on mobile platforms; theory and applications of high-dimensional filtering; analysis of computational cameras; high-frame-rate imaging; general reconstruction problem for images (denoising, deblurring, etc); programmable computational cameras, to name a few. Below is a list of manuscripts published or to appear:

Teaching

I do enjoy teaching very much, whether the topic be computer science or others.

Teaser Winter, 2012: At Stanford, I taught CS478: Computational Photography for the winter quarter of 2012 as a teaching fellow, with Dave Jacobs, in Professor Marc Levoy's absence.
Teaser Winter, 2010: I was a teaching assistant for CS448A: Computational Photography, Winter 2010, under Marc Levoy, responsible for developing the assignments and advising student projects. This experience eventually helped me teach a future iteration of the course (CS478) as a teaching fellow.
Teaser Fall, 2009: I also served as a teaching assistant for CS148: Introduction to Computer Graphics and Imaging , Fall 2009, under Professor Pat Hanrahan.
Teaser Spring, 2008: In addition, I served as a graduate teaching assistant for 6.005: Elements of Software Construction for the spring term of 2008 at MIT (rated 6.8/7.0 overall by students in HKN-run evaluation) for Daniel Jackson and Saman Amarasinghe.
Teaser I volunteered for Educational Studies Program (ESP) at MIT, in 2006 and 2008, to teach an 8-week summer course called Paradox on paradoxes, logic and philosophy of language, to local high-schoolers. I taught the same course also at Stanford Splash in 2012.

Coursework

Teaser Spring, 2009: Check out Glacier Cave (non-Stanford link), for CS348B: Image Synthesis rendering competition, which won the grand prize. This was joint work with Dave Jacobs and Abe Davis. A 2048x2048 render is featured in the second edition of Physically Based Rendering.
Teaser Winter, 2008: Dave Jacobs and I worked on a project titled High dynamic range imaging in the presence of motion for CS223B: Introduction to Computer Vision, but the project is currently shelved till later.
Teaser Fall, 2008: I created a game called Hazard for CS248: Introduction to Computer Graphics video game competition, which was a finalist at the competition. It is basically a wacky arcade spin on the well-known game Minesweeper.
Teaser Fall, 2007: There are two papers from 18.821: Project Laboratory in Mathematics, respectively titled Points on conics modulo p and Finding geodesics on surfaces (joint work with Katherine Redfield and Anand Deopurkar). Interestingly, the latter manuscript has gathered some citations over the years.
Teaser Spring, 2007: I wrote an exposition titled Introduction to infinite Ramsey theory for 18.504: Seminar in Logic.
Teaser Summer, 2006: I was in an undergraduate research program with the Software Design Group at MIT CSAIL, under Professor Daniel Jackson, and helped with some visualization work on the Alloy project, a language for specifying and solving logical constraints. I am credited in the "About" page of the software.
Teaser Spring, 2006: A report on a new prototype of vegetation clipper for demining, from SP.776: Design for Demining is available here (joint work with Aaron Doody.) There are also pictures from a field blast test in 2007.

Stuff

My Erdős number is 4. (Paul Erdős > Endre Szemerédi > Leo Guibas > Natasha Gelfand > Jongmin Baek) My Bacon number is undefined, but if you would like to help me get one, let me know. :-)

I have served as a reviewer for the following venues:

  • ACM SIGGRAPH (2009, 2010, 2012, 2014)
  • ACM SIGGRAPH Asia (2010, 2011)
  • Eurographics (2011, 2013)
  • Pacific Graphics (2013)
  • IEEE ICCV (2007)
  • IEEE ICCP (2010)
  • IEEE TIP (2013, 2015)
  • OSA Optics Express (2010)

I have maintained some interest in the philosophy of language, the philosophy of mathematics, epistemology and logic. I have taken classes from Sally Haslanger, Agustin Rayo, Vann McGee and Richard Holton, and try to keep up by finding things to read.

I do not have much wisdom to share (yet). I can nonetheless offer advice on the courses that I took during my four years at MIT.

I serve as one of MIT's Educational Counselors.

In my spare time, I root for, though not with fervor, the Boston Red Sox, the San Jose Sharks and the San Francisco 49ers. Now that I am no longer an undergraduate, I find myself following the seasons somewhat more loosely than before.

I am a novice rock climber and soccer player. I also try to be a good photographer in my spare time.
