Ethan LaRochelle defends PhD Thesis on Zoom!

Doctoral candidate Ethan P. M. LaRochelle successfully defended his thesis on April 9, 2020 with all committee and himself remote on a Zoom channel.  A large audience logged into to watch him present his work, titled “Modeling broad-spectrum light sources in vivo for applications in cancer treatment and diagnostics”.  As an NSF Graduate Fellow, his work developed algorithms and data analysis in both Photodynamic Therapy dosimetry as well as molecular sensing in Radiation Therapy.  Congratulations Ethan!

Red Journal features Tendler paper on radiation oncology

A publication by Irwin Tendler, a PhD student at the Thayer School, in the Red Journal of the American Society for Radiation Oncology (ASTRO)  has garnered much attention lately through tweets and other online buzz.

The paper, entitled “Experimentally Observed Cherenkov Light Generation in the Eye During Radiation Therapy,” reports that Dartmouth researchers have produced evidence of the flashes of light that patients report seeing during radiation treatment, even when their eyes are closed.  It helps explain the phenomenon and will benefit future research efforts.

Here are some of the recent reports about this exciting development:

Alexander abstract wins ‘Top 3’ award at 2020 Radiosurgery Society meeting

Congratulations to Thayer PhD student Daniel Alexander, whose scientific abstract was awarded one of the “Top 3” prizes by the Physics Section of The Radiosurgery Society.

Dan will present his paper, “Cherenkov Imaging for Adaptive Replanning Guidance in Head and Neck Radiotherapy,” at the group’s 2020 Annual Scientific Meeting in April, which is focused on the use of precision therapies to improve patient care.


LaRochelle abstract receives top selection at WMIC

Ethan LaRochelle recently attended the World Molecular Imaging Congress (WMIC) in Montreal. His abstract titled “Real-time non-contact in vivo pO2 imaging during radiotherapy of unanesthetized mice,” was selected as one of the best abstracts at the conference.  Ethan presented this work during the Highlights in Instrumentation & Methodology session.  Thayer faculty Kimberley Samkoe PhD and Jonathan Elliot PhD, and Optics in Medicine collaborator Dr. Eric Henderson, also attended and presented research at the conference.
