SURF: Announcements of Opportunity

Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Additional AOs for the Amgen Scholars program can be found here.

Specific GROWTH projects being offerred for summer 2018 can be found here.

Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.

Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions! Remember: This is just one way that you can go about identifying a suitable project and/or mentor.

Announcements for external summer programs are listed here.

Students pursuing opportunities at JPL must be
U.S. citizens or U.S. permanent residents.

Project:  Digital Holographic Microscopy
Disciplines:  Physics/Applied Physics, Microbiology/Astrobiology
Mentor:  Christian Lindensmith, (JPL),, Phone: (818) 354-6697
Background:  We are developing digital holographic microscopes (DHM) for terrestrial field use and potential proposal to planetary lander opportunities. DHM uses simple optics combined with computational methods to make high throughput observations at high resolution. Multiple opportunities are possible depending on student interests and backgrounds.
Description:  Multiple types of project are possible, with a variety of subsets in each. DHM uses computational methods to reconstruct images from holograms (interference patterns) that contain compressed information about the path that the light has taken to the detector. We have recently developed a multiwavelength technique that records multiplexed holograms, where each wavelength can be separated and images reconstructed separately. One type of project would involve extension of our existing tools to make the multiwavelength reconstruction faster and more reliable, as well as allow eventual integration with analysis tools. This work would be very software and programming oriented.

A second category of project is analysis of existing hologram data. We have extensive data sets of field and laboratory data and are working to develop automated techniques for evaluating the data. Projects in this category would involve a combination of hand analysis of existing datasets and possible algorithm development to automate the processing, including comparison of the performance of automated methods with expert observations. Work in this category would include using and developing computer tools (starting from Matlab, ImageJ, or similar tools) for hand analysis and algorithm development. Interest in behavior of bacteria or fluid dynamics of small particles would be particularly valuable here.

A third category of project would involve working with JPL optical engineers on setup and calibration of a light-field microscope. Projects in this category would involve hands-on optical setup, alignment, and test, as well as data processing and analysis using a combination of open source and internally developed tools.

Student Requirements:  Some programming and software development ability is required, with preference for at least familiarity with Matlab, python, Java, or ImageJ/FIJI. Familiarity with Fourier transforms and their properties is a plus, as is electricity and magnetism and properties of light. For data analysis oriented projects, some experience or interest in biological microscopy or observation of particles in flows is a plus.
