I develop and implement fast parallel algorithms on very large geometric datasets in CAD and GIS. I've also modeled and processed large terrain databases, e.g., to compress, to compute hydrography and visibility, and to site observers, and compressed 5D environmental data sets. The algorithms are the fastest in their class; awards are listed below.

5   RPI articles

  1. about a completed project that I was part of:

    A Game-Changing Approach: Using the X-Box Kinect as a Sensor to Conduct Centrifuge Research. Team of Rensselaer Researchers Develop New Visualization Method to Evaluate Erosion Quantity and Pattern, Nov 8, 2016, by Jessica Otitigbe.

    The story was also published in Inside Rensselaer, 2016-11-30.

  2. on my student Salles Viana Gomes de Magalhães: The Winning Algorithm, Oct 17, 2016, by Mary Martialay.

8   Office hours

  1. After almost every class, I stay as long as there are questions. Other people are also welcome to catch me then. I also sign forms at the start of class.
  2. Otherwise, email to discuss another time. Mon and Thurs afternoons and some Wed afternoons are best.
  3. If you me a PDF of the form; I'll email back a PDF of the signed form.

10   Misc advice

  1. For grad student applicants. (Apparently only ONE person a year reads this.)
  2. For Doctoral Qualifying Exam (DQE) examinees. (Summary: know your material.)
  3. For doctoral candidacy examinees. (Summary: have a plan.)
  4. For job seekers, particularly for older professionals.
  5. Textbook reviewing criteria. (Summary: make it easy to teach a good course.)

11   Misc

  1. Famous RPI graphics-related grads. It is possible to survive RPI and prosper.
  2. RPI pages: Academic calendar. (When do classes start and end; holidays.)
  3. My travel photos.

12   Site organization

  1. My home page's location is currently https://wrf.ecse.rpi.edu/nikola/,
  2. http also works.
  3. The previous version of my homepage is https://wrf.ecse.rpi.edu/pmwiki/. It contains many pages that have not (and will not) be converted from pmwiki to nikola.
  4. Other public files are under https://wrf.ecse.rpi.edu/; they are all linked from one of the above two dirs.
  5. http://wrfranklin.org/ currently redirects to wrf.ecse.rpi.edu. However, at some time in the future, it might become my home page.
  6. https://wrfranklin.org/ currently gives a browser error because wrfranklin.org doesn't have an SSL certificate.

I welcome questions and problem reports.
