Morris Named 2018 MIT Impact Fellow

January 15, 2018

Morris Vanegas was just named a 2018 MIT Impact Fellow! The program is tailored towards career development for post-doctoral and advanced pre-doctoral trainees. The group and one-on-one mentoring helps fellows articulate the impact of their research to a brach audience and help identify actionable opportunities to strengthen their work focus. See details of the Impact Program here.

MCX Workshop 2018 announced

April 2, 2018

The 2nd MCX/MMC Training Workshop will be held on April 2, 2018 in Hollywood, Florida, USA, as a pre-conference event prior to the OSA BIOMED'18 Conference. The workshop provides hands-on training on building fast and accurate Monte Carlo (MC) biophotnics simulations using our open-source software - MCX (GPU accelerated MC simulator) and MMC (Mesh-based MC for accurate anatomical modeling). Registration is FREE! Register at

Morris Named 2018 Dent Scholar

November 9, 2017

Morris Vanegas was just named a 2018 Dent The Future Scholar! This award comes with a complimentary pass to Dent 2018, a flagship conference for a community of entrepreneurs, executives and creatives who are driven to "put a dent in the universe." Dent looks for scholars who work at the intersection of art, science, and impact. Morris was chosen for his work at co-director of the MIT Open Mind::Open Art Gallery in January 2017. See details of Dent 2018 here.

IDEA Venture Accelerator Prototype Funding Winner!

August 22, 2017

Morris Vanegas was recently awarded funds to complete his prototype of a portable Internet of Things (IoT) suite of sensors to capture temporal artist physiological and environmental data by Northeastern's IDEA Venture Accelerator. The stand-alone 3 shelf stand and light also uses OpenCV to non-invasively capture an artist's work. The images and data are then presented in an interactive GUI.

MCX Workshop 2017 at ISEC

August 8-9, 2017

Thanks to those that attended our 1st two-day workshop on Monte Carlo eXtreme for biomedical optics research at ISEC on August 8th and 9th. We hope we were able to provide our software users with tips, insight, and knowledge on how to best take advantage of our in-house developed high-performance Monte Carlo photon transport simulation platforms. Many thanks to our speakers and COTI student presenters, as well as to the attendees for their active participation and discussions. We plan on making this an annual event, so feel free to reach out if you want to attend in the future. See the images below to relive the experience!

Build your own GPU rack!

In support of our MCX 2017 workshop, Dr. Fang and Morris Vanegas built a rack that houses 12 GPUS, 3 power supplies, and is made of 80-20s extrusion bars. Users will be able to run monte-carlo simulations by remoting into these machines. A quick test of 5x 1080Ti GPUs with a single power supply was able to simulate 311955.21 photons per ms, making it our fastest setup to date!

We've also documented the process of building the GPU rack below:

Looking for a postdoc position?

As our lab continues to expand, we are looking for highly qualified candidates for two postdocs in the near-term for NIH-funded research projects. If you, or someone you know, is a great fit and would like to join our team located at ISEC, reach out to us!

Computational Biophotonics

This position is perfect for someone with a strong background in computational algorithm development, GPU computing, and computational physics. Proficiency in C/matlab software development is a necessity. Apply here!

Optics Engineering

We are also looking for a postdoc with a background in optical instrumentation, medical device design, and mobile-app development. A strong electrical engineering background would be a plus. Apply here!
