2022 Candidate Biographies and Vision Statements

For President-Elect Position: Listed in alphabetical order by last name.

Ferri, Rafaele (Italy)

Dr. Ferri is the scientific Director of the Oasi Research Institute – IRCCS in Troina (Italy) and chairs its Sleep Research Centre. Dr. Ferri is an expert in sleep medicine, in areas of research, clinical care and public awareness. He has global collaborations with colleagues from all over the world. During the past 30 years he has worked to expand sleep medicine in the areas of neurophysiology, sleep related movement disorders and pediatrics. Although Dr. Ferri has a prominent research career with >500 publications, his personal mission is to advance sleep medicine globally. For this purpose, Dr. Ferri counts with the support or international leaders to make sleep awareness, education and promotion of healthy sleep a top priority during his term at the World Sleep Society. He has prominent leadership experience as President of the Associazione Scientifica Italiana per la Ricerca e l’Educazione nella Medicina del Sonno (ASSIREM), Past-President of the Italian Association of Sleep Medicine (AIMS), and Member-at-large of the International Restless Legs Syndrome Study Group (IRLSSG); he has been Secretary and then Vice-President of the European Restless Legs Syndrome Study Group (EURLSSG).


I fully embrace the primary purposes listed in the WSS bylaws “to advance knowledge about sleep, circadian rhythms, sleep health, and sleep disorders worldwide, especially in those parts of the world where this knowledge has not advanced sufficiently”. For this specific purpose, the geographical location of my workplace is ideal for its proximity to Northern Africa and Middle-East, as well as Eastern Europe. For the rest of the World, I am an expert traveler and my continuous and punctual attendance at all the major scientific events for more than two decades attests to my capacity to be present when and where such presence is needed. In addition, I am an expert user of the modern ITT technologies, which enable me to keep constant contact with a number of colleagues and collaborators worldwide and that I can use also to carry out my work as a WSS President.

To reach these goals, in addition to the existing initiatives, I would put forward the following activities:

  1. To advance knowledge about sleep, circadian rhythms and sleep health and disorders I propose:
  1. Support and expand current WSS programs like the ISRTP, to promote more sites and more countries
  2. Provide resources for collaboration with underrepresented countries
  3. Establish and promote a database of resources for local meetings as list of speakers, topics courses etc
  4. Promote and support affordable testing and treatment options that allow for the diagnosis and treatment of sleep disorders in underrepresented areas (similar to the EBC VoT project)
  1. To specifically reach underserved areas of the world where sleep medicine is not developed
    1. Promote programs, conferences in person or online in various regions
    2. Establish ambassadors to connect with various underrepresented areas
    3. Support the effort of the World Sleep Academy and contribute to in person rotations
    4. Translate educational materials in various languages
  2. To grow and maintain a successful leadership team at the WSS
    1. Establish regular team building and leadership training opportunities.
    2. Partner within the WSS with senior and mid-career growing future leaders for mentoring.
    3. Involvement of the major patient organizations with a space devoted to them during the WSS congresses
  3. To promote WSS globally
    1. Young Sleep Experts Network (Education and Awareness through social media: Facebook, Twitter, etc.)
    2. Accreditation at the UN, WHO, etc. (if not done already)

I would like to add that I speak English, French, and Italian fluently, and collaborate often with colleagues from other languages such as German and Spanish.

When talking to my coworkers and collaborators they describe my leadership skills as inclusive, non-discriminatory, committed, motivating and inspiring. As a recognized leader in the field, I feel that the extent, depth and quality of my work and collaborations attest to the required abilities to lead an organization such as the WSS.



Thomas, Robert (USA)

Dr. Thomas’s background includes Internal Medicine, Neurology and Sleep Medicine. He has been deeply engaged in WASM/WSS processes and development from the onset of the association. His research spans cognition in relation to sleep and its disorders, signal analysis in sleep medicine, sleep- breathing outcomes, and functional imaging of cognition in sleep disorders. He holds twelve patents and has been involved in developing several innovative approaches to diagnose and treat complicated forms of sleep apnea and has articulated a new approach to sleep physiology termed “sleep effectiveness”, which is a cross-physiology integrative approach to characterizing sleep state using cardiopulmonary coupling estimates. His laboratory generates novel approaches and analysis tools for probing sleep signals – ECG, EEG, respiration and multi- signal integration approaches. He has been funded by a K23, an RC1, R01’s, R21’s, SBIR’s, a CADET-II program, and Foundation grants. He developed an FDA-approved wearable device – the M1/SleepImage system – for dynamic sleep quality tracking. He is an acknowledged expert in the area of treatment of central and complex sleep apnea and periodic breathing, utilizing CO2 regulation and multi-modal approaches. He runs a Circadian Medicine program and has described a novel circadian hypersomnia syndrome. He has developed auto-CPAP algorithms from concept through regulatory submission, now in FDA approved products. He is the Associate Director of the AASM accredited clinical sleep center and Director of the Institute for Personalized Sleep Health and developed the ACGME accredited sleep medicine training program at the Beth Israel Deaconess Medical Center, Boston.


What would I like to do for the WSS and patients with sleep disorders?

The AASM scoring manual is holding the field back. Automated analysis of signals is the only way for large scale implementation, including spectral analysis, epoch free sleep designations, alternate state and signal EEG analysis. I believe that the WSS should undertake a Sleep Mapping Manual which builds out on the current foundations and integrates the various methods that are floating around, at least solidifying the methodology and providing a blueprint for development.

There is a need for a WSS-driven world-wide clinical trial network for pragmatic and focused randomized clinical trials.

The WSS should create a massive “Virtual Sleep Medicine and Technology Training Program” by tapping into conferencing technology and the vast expertise of members, with the goal to train thousands of individuals a year. Such scale is possible, and indeed necessary.

Patient care
The WSS is overly focused on the near-term health of its membership, but we need a much longer-term perspective and plan as well. We need to provide value to others (e.g., heart failure, cognition disorders, stroke – specialists who take care of such patients) by formally developing co-management programs through interactions with the respective bodies in each country.

The WSS should create the blueprint of a pyramidal or “queen-bee” structure for sleep medicine: with the sleep-trained physician at the peak (or the queen), directing the lower components of the pyramid. There is absolutely no chance that training or certifying a few physicians here and there will make tangible difference to the care of the vast majority patients.

Non-MDs could be trained large scale (tens of thousands – Internet-based teaching), with the essential skills to implement management plans and protocols.

The WSS is setting standards but should also challenge individual countries to present and implement a plan to respond to the needs of the vast numbers of undiagnosed and untreated patients. The WSS needs to generate and publish patient care access and metrics from all participating countries (e.g., ratio of sleep trained MD’s to population, sleep testing resources, diagnosis and treatment of sleep disorders/population)

Industry Interactions
This needs a substantial re-think from the standpoint of driving and demanding specific innovations that enhance patient care world-wide.

Closing comments
The WASM/WSS has been of great value to the sleep field in advocacy, lobbying, interactions with government and education, but tittle of the new biology of sleep and related sciences and the vast power of computing has been integrated into the foundations of the past. I will seek to initiate a style of greater self-criticism and introspection than there is now and ask the difficult questions which in time will provide answers closer to the biological truth. I am also very interested in the WSS leading the way in the appropriate use (proposed standards) of wearable devices in clinical practice, mobile technology including smartphone applications that enable sharing and querying knowledge in routine clinical practice.

Malik, Nudra (Pakistan)

I am an Assistant Professor in the Department of Applied Psychology at Lahore College for Women University, Lahore, Pakistan. I am interested in participating in the Governing council of World Sleep Society as this is an excellent opportunity to promote sleep, which I feel is one of the most important area for health protection to prevent long term comorbidities. I have dedicated a major part of my career to this subject as my entire PhD dissertation focused on sleep health and sleep disorders. I developed a standardized tool on sleep disorders to screen people for the presence of sleep disorders. Other than developing this scale, my dissertation focused on screening the respiratory disease patients for sleep issues and disorders. I have been actively working with an American board of Sleep Medicine certified doctor here for the assessment and psychological management of individuals with sleep problems. I have worked extensively in the area of sleep disorders and am actively leading behavioral and population level sleep research here.

I am an early career researcher and am making efforts to contribute to this field within my capacity and resources. I feel that the subcontinent region where I reside (Pakistan) lags behind largely when it comes to awareness and management of sleep health. I am highly dedicated to engaging globally to propel this field through my professional service and a strong representation at WSS. It would be an honor to serve as a Director at Large (Asia). I would bring my enthusiasm, passion, and work ethics to this position.

Zak, MD is an associate professor at the University of California San Francisco, working in the UCSF Sleep Disorders Center.  My interest in the World Sleep Society is to develop a fund that would focus on developing low-cost, low-resource sleep solutions for the developing world. My professional experience includes working with the development of evidence-based medicine recommendations for the AASM, now on the Guidelines Advisory Panel and previously on the Standards of Practice Committee. I have also been on review committees for the American Sleep Medicine Foundation. I have been a member of the International RLS Study Group (IRLSSG) and served as treasurer and am working on the IRLSSG Leg Movement Detection Task Force. I am part of the review committee for the WSS consumer publication, Healthier Sleep Magazine, and will soon be among the many clinicians assisting with the World Sleep Academy under the direction of Dr. DelRosso. My clinical research has been directed at varied topics. I am now focusing on sleep during the menopausal transition, analyzing longitudinal data on a community-based sample, and will soon be working on a study examining how treating OSA and insomnia can affect symptoms of Gulf War Syndrome.
