New Research Publication: Spectroscopy Works Across Oral Cavity Sites
The OTO‑COATI Lab is pleased to announce a new paper in the American Journal of Otolaryngology: “A prospective cohort study testing whether oral cavity mucosal tissue variability influences elastic scattering spectroscopy (ESS) measures,” made available online April 14, 2026.
Authors include Mitali Sakharkar (BU medical student, OTO‑COATI Lab), Gabriele Spokas (UNC graduate student, OTO‑COATI Lab), Parth Jalihal (BU medical student), Lucas Berry (OTO‑COATI Lab research specialist), Eladio Rodriguez‑Diaz, PhD (BU), Irving Bigio, PhD (BU), Gregory Grillone, MD (BMC Otolaryngology chief and OTO‑COATI Lab faculty), and Gintas Krisciunas, PhD (OTO‑COATI Lab Director). Special thanks to Devin Lucas (OTO-COATI Lab research coordinator) for contributing an illustration of the oral cavity.
This work was conducted in collaboration with Boston University’s Biomedical Optics (BMO) Lab, a longtime partner in our spectroscopy studies for head and neck cancer detection.
WHY THIS MATTERS
A key aim of our lab is to develop elastic scattering spectroscopy (ESS) to guide surgeons in detecting oral cancers during surgery. Prior work showed ESS is promising for margin guidance, but we lacked clarity on whether normal anatomical differences across the oral cavity would affect ESS readings. In this prospective cohort study, the authors show that ESS measures are largely unaffected by locoregional variations in normal mucosal tissue. Put simply: ESS appears to perform consistently across different oral sites (tongue, inside of the cheek, gums, etc.), supporting its broader clinical utility for oral cancer detection.

Congratulations to the authors and collaborators for this important step toward translating ESS into a reliable surgical and diagnostic tool.

Congratulations to Lucas Berry for Earning SOCRA Certification
Lucas joined the OTO‑COATI Lab in 2020 and is the lab’s longest‑serving staff member. He plays a central cross functional role in the Lab, contributing expertise in research operations, regulatory requirements, and data management for nearly all of the Lab's projects. He also manages lab logistics and is involved in training students and staff.
With his CCRP, Lucas brings strengthened regulatory and data‑management expertise to every project. That expertise helps accelerate study start‑up, improve the reliability of study data, and — most importantly — enhance protections for the patients who volunteer for the lab’s research.
Lucas on earning the CCRP:
"First, I must offer my deepest gratitude to everyone in the OTO‑COATI family, especially my mentor Gintas. Earning the CCRP designation from SOCRA wouldn't have been possible without their trust and guidance. I'm lucky to work with brilliant people who are — or aspire to be — clinicians and scientists. While they work to invent new ways to detect cancer during surgery or to improve widely used diagnostic instruments, I am excited to guide them through the minefield of research regulations and processes. These types of collaborative efforts help bring great ideas from bench to bedside, and being able to help my team in this way is a tremendous privilege. I pursued the CCRP so I can do an even better job of it."
Congratulations, Lucas — and thank you for continuing to strengthen the lab’s research quality and patient protections.
New Research Publication: Laryngeal Edema & Aspiration in Acute Respiratory Failure Patients
We're excited to share a new paper from the OTO‑COATI Lab, published in the European Archives of Oto‑Rhino‑Laryngology and made available online March 5, 2026: “Identifying the association between post‑extubation laryngeal edema and aspiration in acute respiratory failure patients.”
Authors include Devin Lucas (OTO-COATI Lab clinical research coordinator), Ryan Peterson, Jared Rieck, Moses Owusu, Edel McNally, Rebecca Scheel, Patricia Cavanagh, Susan Langmore, Ann Kearney, Joseph Levitt, Jonathan Siner, Rosemary Vojnik, Heather Warner, Mitali Sakharkar (BU medical student and OTO‑COATI member), Winston Liu (BU undergraduate and OTO‑COATI member), Alix Rubio (OTO‑COATI alumnus), Marc Moss, and Gintas Krisciunas (OTO‑COATI Lab Director).
This study was done as part of a nationwide consortium looking at complications from acute respiratory failure, with partners from University of Colorado, Stanford, Yale, and a talented group of speech‑language pathologists.
The authors looked at clinical outcomes and FEES (flexible endoscopic evaluation of swallowing) videos from 120 patients who had been intubated, to see how laryngeal swelling after extubation relates to aspiration.
Key takeaways:
- Swelling of the aryepiglottic folds stood out as the strongest predictor of post‑extubation aspiration.
- Weakness independently raised the risk of aspiration.
These findings help us better understand why some patients aspirate after extubation and point toward targets for future research and interventions to reduce those risks.
Huge congratulations to the whole team — and thanks to our consortium collaborators for making this important work possible.

New Research Publication: Racial Representation Disparity in HNC Trials
The OTO-COATI Lab is pleased to announce a new paper published in Head & Neck: “The Persistence of Racial Representation Disparity in Head and Neck Cancer Clinical Trials in the United States: A Temporal Analysis of 20 Years of Data,” available online February 13, 2026.
Authors include medical student and OTO-COATI lab member Lalita Sabat, Arnavaz Hajizadeh Barfejani, lab alumnus Grace Chow, Melani Zuckerman, Jungwun Lee, Heather Edwards, and lab director Gintas Krisciunas.
This study analyzed enrollment data from more than 100 head and neck cancer (HNC) clinical trials conducted from 2002–2020 and found that minority groups remained consistently underrepresented despite prior efforts to promote equitable trial participation. The work highlights ongoing disparities in clinical research and underscores the need for renewed strategies to ensure clinical trial populations reflect the diversity of patients affected by HNC.
We thank our colleagues in the BU Department of Otolaryngology (Drs. Hajizadeh Barfejani, Zuckerman, and Edwards) and Jungwun Lee from BU SPH for their contributions. Congratulations to the authors for this important contribution to the field!
