Monthly update - July 2019

August 1, 2019

A number of students have been busy in the lab this summer, making some great progress on their experiments. Here's a few highlights from what we've accomplished:

1. We have put the finishing touches on our lab's first official paper! Hopefully there will be many more to come. 

Monthly update - June 2019

July 1, 2019

I'll try to post monthly updates from here on out. Here's what the Computational Optics Lab has been up to this June:

Welcome to Pavan!

January 13, 2019

We are happy to welcome Pavan Konda to our group. Pavan recieved his PhD and performed a short post-doc at the University of Glasgow, where he worked on a number of different optical experiments, including Fourier ptychography and miniaturized microscopes

Congratulations to Eric, who was awarded a Pratt Fellowship!

November 14, 2018

Eric has been and will continue to work on a project titled, "Micro-camera design for neural imaging"

Welcome to Wenhui

November 6, 2018

Wenhui Liu is a new visiting PhD student from Tsinghua, who will be working on problems related to parallelized detection of scattered light.

Lab setup: it might not look like much, but this is where the magic happens!

September 14, 2018

We've got some optics tables in here and are working to fill this lab space with fun equipment. Stop by CIEMAS 2584A if you'd like to come check out what we're working on!

Arrived at Duke!

July 2, 2018

I have recently arrived at Duke University and have begun to setup my lab! My office is CIEMAS 2569 and my lab is in CIEMAS 2584, feel free to stop by and say hi at any time, and/or send me an email if you are interested in joining in on any of the new projects that I have planned!

New paper: deep learning can "teach" a microscope how to capture better images

October 6, 2017

Deep learning algorithms have become a popular way to extract useful information from images (e.g., to classify, segment and track objects).

Young Researcher Award and $100K Prize

July 31, 2017

I was recently awarded a nice price from Friedrich-Alexander University (FAU): the SAOT Young Researcher Award, which comes with some prize money and a guest professor appointment. I will spend the beginning of 2018 as a... read more

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

May 1, 2016

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:
