Optical scattering in tissue - 2 new papers

July 25, 2017

We've been working hard trying to figure out some better ways to scan light around deep within tissue.

Einstein Foundation article and video

March 29, 2017

The Einstein Foundation Berlin just wroteup a short piece about me and my research.

New paper about on-chip holographic video

February 20, 2017

We have a new method that can take really fast videos of small micro-organisms that swim around on top of a sensor. It is based on a modified phase retrieval algorithm. You can find the paper here.

Invited talk at 2016 Lasers Congress

November 1, 2016

I recently gave an invited talk at the Lasers for Sensing and Free-space Communication conference in Boston, which included a very interesting mix of research fields! 

3D microscope technique published in Optica

August 15, 2016

We describe how a new microscope can create 3D images of thick, primarily transparent specimens in a new article in Optica.

Heading back to to Duke!

June 1, 2016

I will join Duke University's Biomedical Engineering Department as an assistant professor in 2018, after finishing my postdoctoral fellowship in Berlin. If you hope to start graduate school or a postdoc in a couple of years and find my work interesting, please feel free to get in touch!

Awarded Charles Wiltz prize at Caltech

I was awarded this prize from Caltech for "outstanding research in electrical engineering towards a PhD," which you can read more about here.

New paper about microscope resolution

February 1, 2016

Characterizing the resolution of a microscope can be a little bit tricky. In the following paper, we outline a set of guidelines and propose a common resolution standard for a particular class of microscopes that image with coherent light:

I just graduated with my PhD!

November 1, 2015

Over the past 6 months, I've mostly been working on a way to extend our Fourier ptychographic method to operate in 3D. Now, we can use a regular microscope and an LED array to capture the full volume of a thick biological specimen:
