Brief Summary of Project(s):
Many people with cystic fibrosis (CF) have sinusitis and olfactory dysfunction. The landscape of clinical care for people with CF is rapidly evolving with the expansion of disease-modifying therapies. Our group is conducting research investigating the impact of new CF therapies on sinusitis/olfaction, effects of sinus surgery in this population, and whether early intervention enables mitigation or prevention of disease complications. Patient-reported outcome measures, olfactory testing, biospecimens, and CT/MR imaging are employed in these longitudinal, prospective studies.
Sinonasal cancer is an understudied, rare disease comprised of heterogenous tumor types. Partnering with other centers across the U.S., our research team participates in a multi-institutional, prospective, database to study sinonasal cancers, incorporating both quality of life and
oncologic outcomes, as well as molecular studies.
Recent articles on PubMed provide further detail on specific topics for the projects listed above. The above work has been supported by the NIH/NHLBI, Cystic Fibrosis Foundation, International Society for Allergy and Inflammation of the Nose, and American Academy of Otolaryngology CORE grant program.
Opportunities for trainee participation in research exist, with preference given to individuals who are available to participate for a substantial duration of time. Please email the PI, [email protected] or lead research coordinator Rhea Churi, [email protected] with inquiries.

Primary Interests: Sleep Surgery (Sleep Apnea, Snoring)
Brief Summary of Project(s):
We are focused on improving the surgical evaluation and treatment of obstructive sleep apnea. We are committed to conducting scientific examination of innovative approaches to procedure selection as we identify the promise and limitations of current approaches while also looking to develop novel treatment strategies.
Drug-Induced Sleep Endoscopy (DISE)
There are many procedures available to treat patients with obstructive sleep apnea. Successful surgical treatment is based on accurately identifying the physical cause of obstructive sleep apnea. This can guide the selection from among these procedures, enabling targeted, effective treatment. During DISE, surgeons look inside the throat with a flexible fiberoptic endoscope while a patient is sedated in the operating room. We have led multicenter cohort studies demonstrating DISE findings that are associated with outcomes of upper airway surgery, including hypoglossal nerve stimulation.
Combining Surgery and Medications to Treat Obstructive Sleep Apnea
Anatomical blockage of breathing is the most important cause of obstructive sleep apnea. Surgery addresses anatomy by removing and/or repositioning tissue to open the airway. However, some patients with obstructive sleep apnea continue to have this condition even after surgery that normalizes their anatomy. Research over the past two decades has shown that there are non-anatomic causes of obstructive sleep apnea. With funding from the National Institutes of Health, we are examining how we select patients for surgery, how surgery improves anatomy, and whether we can use medications to treat these non-anatomic causes to improve obstructive sleep apnea if patient do not do well with surgery.

Brief Summary of Project(s):
Regenerative medicine in otolaryngology.
The overarching goal of this lab is to develop innovative and cell-based therapies to improve voice and swallowing. Many patients develop difficulties in these quality-of-life domains after treatment for head and neck cancer. The lab uses in vivo models to implant cell-based replacements in the vocal folds. Data from vocalizations, microscopy, and molecular analysis are then analyzed.

Brief Summary of Project(s):
Project 1: An exploratory study to evaluate the safety and effectiveness of APG-157 as an adjuvant therapy for patients with head and neck squamous cell cancer (HNSCC) of the oral cavity. Funding: Aveta Biomics, Inc.
Phase II is near completion and enrolls oral/oropharyngeal cancer patients who are scheduled to undergo surgery. They will receive APG-157 (200 mg) TID for a 4-week course prior to their surgery. Blood and saliva are collected prior to and each week during treatment, as well as one week after treatment. At the time of surgery, tumor specimen is harvested. Blood, saliva, and tumor tissue will be analyzed for cytokines (GM-CSF, TNFα, IFN-γ, IL-1β, IL-10, IL-12 p70, IL-2, IL-6 and IL-8) to look for changes after APG-157 treatment.
Project 2: Outcomes research in endoscopic skull base surgery
We have been performing anterior endoscopic skull base surgery with the neurosurgery department for over 15 years and have accumulated a database of nearly 1500 patients. Previous projects using this database have analyzed outcomes, complications, quality of life issues, and cost of care, resulting in numerous publications which have had a positive impact on algorithms for clinical care. We continue to analyze information as the database grows, and this will yield valuable information for future treatment and quality improvement.

Brief Summary of Project(s):
UCLA SPAPL Projects
Lab Research Mission:
- To understand the mechanisms involved in speech pattern recognition by the electrically stimulated auditory system, and further, the plasticity of the auditory cortex.
- To provide innovative speech software to people with hearing problems based on the state-of-art speech technology and recent research findings in cochlear implants, hearing aid, speech and hearing science, language development, and auditory plasticity.
Lab Research Projects:
One large ongoing project in the laboratory is “Speech on Speech (SOS) Masking Project�. This project is to understand how people with different hearing status, age, and music experience may perform differently when the target speech is masked by different speech in a realistic listening conditions. Several underlying auditory mechanisms will be explored, including energetic masking (EM) vs informational masking (IM), listening in spatialized noise (LiSN), contralateral ear masking (CEM), and listening in asymmetric masking (LISM). The subject groups may include normal-hearing (NH) people, cochlear implant (CI) patients, bimodal CI, bilateral CI, and patients with single-sided deafness (SSD). We will also evaluate the developmental effects of speech on speech masking by comparing the data in adult and children. Furthermore, we will evaluate whether the people with music experience can perform better in difficult listening conditions, such as speech on speech masking by comparing the speech performance between musicians and non-musicians. There are many other ongoing research projects in the laboratory, including the effects of training on the integration of mismatched acoustic and electric hearing, effects of electric stimulation on tinnitus and speech performance in SSD patients, effects of age and listening modes on spectral resolution and speech recognition in noise, benefits of binaural listening in CI patients, and the development of auditory training software for other languages, such as Spanish.
Eligibilities and Responsibilities:
- Medical students, undergraduate, or graduate students are welcome to participate in one or multiple projects;
- Scope of works includes subject recruitment, data collection, data analysis, and/or manuscript writing;
- Projects are open-ended with flexible working schedules and timelines
Marco Giovannini, MD, PhD
Professor-in-Residence

Director, Neural Tumor Research Laboratory
Primary Interest: Oncology, Tumor Biology and Genetics
Brief Summary of Project(s):
The long-term interest of Dr. Marco Giovannini's research laboratory is the genetics and biology of human cancer predisposition and progression. His lab has made a number of seminal contributions to the characterization of major tumor suppressors such NF1, NF2, p53, APC, and SMARCB1. Using a variety of genetically engineered mouse and pig lines to study the effects and interactions of these genes in vivo, the lab strives to develop models that faithfully replicate human tumorigenesis. These in turn are utilized for the development and testing of novel treatments and therapeutics.
The lab's present research interests focus on the function of the NF2 tumor suppressor gene, mutated in patients with schwannomatosis with the goal of providing novel therapeutic options. Subjects who inherit a mutated allele of the NF2 gene inevitably develop schwannomas affecting particularly the superior vestibular branch of the 8th cranial nerve, usually bilaterally. Meningiomas and other benign central nervous system tumors such as ependymomas are other common features. Recent studies suggest that the NF2 protein may coordinate the processes of growth-factor receptor signaling and cell adhesion. Varying use of this organizing activity by different types of cells could provide an explanation for the unique spectrum of tumors associated with NF2 deficiency.
The lack of satisfactory treatments for NF2-related tumors represents a significant unmet medical need. The overarching goal of Giovannini's lab is to find drugs that will improve the treatment and long-term survival of NF2-related schwannomatosis patients, and ultimately provide them with a better quality of life.

Our laboratories offer different opportunities for basic and clinical research in the human inner ear for H&N Residents, Medical Students and undergraduate students. This is a short list of different research opportunities:
- Cellular and Molecular biology of the normal and implanted human cochlea. We are investigating the effects of the cochlear implant (CI) in the different cell types of the human inner ear using immunohistochemistry and 3D reconstruction. We are investigating the presence of immunoreactive macrophages in the normal and implanted cochlea.
- Cellular and molecular biology of Meniere's disease. We have been investigating the effect of Meniere's disease in the vestibular sensory hair cells and supporting cells for several years. We are interested in the identification of blood labyrinthine cellular markers in the human inner ear using immunofluorescence and RNAScope techniques. We are interested in the identification of ultrastructural alterations in the microvasculature of the human macula utricle obtained from ablative surgery from patients diagnosed with Meniere's disease. For this purpose we use state of the art electron microscopic techniques and laser confocal fluorescence microscopy.
- The blood Labyrinthine Barrier of patients diagnosed with Meniere’s disease. We are extending our studies on the microvasculature using celloidin-embedding sections from temporal bones obtained from patients diagnosed with Meniere's disease. We are investigating the neurovascular unit (NVU) in the spiral ganglia neurons from Meniere’s disease patients and to compare with age match normal subjects.
- The cellular and molecular biology of supporting cells of the human and mouse macula utricle. Supporting cells are important for hair regeneration as well as for secreting otoconial proteins. To investigate the cellular organization we use laser confocal microscopy and electron microscopy, we offer opportunities for research in this area.
