Principal Investigator -
Alexander "Zandy" Hillel, MD

I am an Associate Professor of Otolaryngology - Head and Neck Surgery at the Johns Hopkins School of Medicine. Originally from New York, I graduated from Dartmouth College and went to Tulane University School of Medicine. After completing residency in the Johns Hopkins Department of Otolaryngology-Head and Neck Surgery, which included a three-year research fellowship in biomedical engineering, I finished my training with a Laryngology fellowship at the Emory Voice Center in Atlanta.

I joined the faculty at Hopkins in 2013 and established our laboratory investigating laryngotracheal stenosis. My current clinical and surgical expertise focuses on airway and voice disorders, including endoscopic and open treatment of laryngotracheal stenosis, treatment of professional voice, and spasmodic dysphonia.  I am also the Medical Student Director for the Department of Otolaryngology and am passionate about facilitating medical student education in Otolaryngology.

Kevin Motz, MD

I am a 7th year Resident Physician training at the Johns Hopkins Hospital in the Department of Otolaryngology - Head and Neck Surgery. As part of my residency training, I completed a NIH-funded T32 training fellowship and spent 2 years in this lab. After completing residency training, I will pursue a fellowship in Laryngology at Vanderbilt medical center with the hopes of  advancing my career as a surgeon-scientist.  

I was born and raised in Hagerstown, Maryland and graduated from Villa Julie College in 2009 with a degree in Biology. Afterwards, I received my medical degree from Georgetown University in 2013, and began my Otolaryngology training at Johns Hopkins the same year.

I am an avid golfer, love my dog, and am the #1 Ravens fan!!

Ioan Lina, MD

I am currently a 3rd year resident in the Department of Otolaryngology - Head and Neck Surgery at Johns Hopkins Hospital. Over the next two years, I will be joining Dr. Hillel's lab as part of a T32 funded training grant. Specifically, my interests will focus on the development of biomaterials and novel therapeutics to treat laryngotracheal stenosis. During this time, I hope to continue to advance as a clinician-scientist and will one day integrate the principles I learn into my clinical practice.

I was born and raised in Sudbrook, Maryland and graduated from Johns Hopkins University in 2012 with a degree in Biomedical Engineering. I went on to obtain my medical degree from University of Maryland School of Medicine in 2017, and began my Otolaryngology training shortly thereafter.

In my free time, I love to hike, play tennis, and run around the beautiful Baltimore harbor. 

Ruth Davis, MD

​I am currently a 3rd year resident in the Department of Otolaryngology - Head and Neck Surgery at Johns Hopkins Hospital. I am originally from Madison, Wisconsin and graduated from the University of Rochester with a degree in Biomedical Engineering in 2012. I then completed my medical training in 2017 at the Cleveland Clinic Lerner College of Medicine. 

My lab interested are specifically on investigating the role immunological markers and therapeutics on LTS.

Dacheng Deng, MD PhD

I have been a Research Specialist in the Hillel Lab since 2013. I am originally from China, and received my medical degree in 1994 from the Peking Union Medical College and Chinese Academy of Medical Sciences. As a physician in China, my specialty was in Hematology-Oncology.

Since coming to the United States, I have worked in a variety of labs and I have experience in a large variety of research techniques. I have spent time at the Johns Hopkins School of Medicine, Harvard Medical School, and the University of Michigan. I hope to use my extensive background in immunology to continue investigating the etiology of airway inflammation and scar formation.

Hsiu-Wen (Irene) Tsai, PhD

I am currently a postdoctoral fellow in the Department of Otolaryngology-Head and Neck Surgery at Johns Hopkins Hospital. I joined Dr Hillel’s lab in 2018. My current research is focusing on investigating the pathogenic mechanisms of iatrogenic laryngotracheal stenosis and developing specific therapeutic strategies.  
I received my Ph.D degree in Physiological Sciences at University of Florida. My area of expertise includes respiratory physiology, neuroscience, molecular biology and metabolism.
