Welcome to the online home of the Sleep, Suicide, and Aging lab at Mississippi State University.  Our interests are broadly in these areas, with most of our research spanning at least two of them.  For instance, we commonly investigate the interplay of sleep disorders and suicidal ideation.

Our research projects are highly influenced by our current graduate students, as you will see.  We believe it is important to follow our passions and to do the research we believe is important to do regardless of whether or not it may lead to grant funding.  That said, we regularly seek out grant funding.  Our lab has been continuously funded since 2013 with our funding coming from the Substance Abuse and Mental Health Services Administration (SAMHSA), the National Institute of Mental Health (NIMH), the Military Suicide Research Consortium (MSRC), the Centers for Disease Control and Prevention (CDC), and the Mississippi Department of Mental Health.  Dr. Nadorff has served as PI on over $3.75 million dollars of external grant funding.  He has also served as the director of the Clinical Psychology program at Mississippi State since 2014.

Please explore our website and learn more about what we do.  If you have any questions, please don’t hesitate to get in touch with Dr. Nadorff.


The focus of our lab is the interplay of behavioral sleep medicine, suicidal behavior, and clinical geropsychology.  Our projects are determined in large part by our students’ interests.  Below are the lab projects that we are currently working on, or hope to do in the near future.  

Comparing in-person and application-driven Imagery Rehearsal Therapy for Nightmare Disorder

There is a strong literature supporting the use of Imagery Rehearsal Therapy for nightmare disorder.  However, given the few number of clinicians who specialize in Behavioral Sleep Medicine, it is commonly difficult to find a therapist to provide the treatment.  Recently the VA released a smartphone application based upon this innovative treatment, but research has yet to examine whether or not the application is as effective as Imagery Rehearsal Therapy provided in-person.  For Kat Speed’s dissertation, we will be conducting a randomized controlled trial comparing the effectiveness of Imagery Rehearsal Therapy being provided by a clinician in-person to the treatment being provided through the smart phone application.  If you are an active duty member or Veteran with nightmares and are interested in the study please contact Dr. Nadorff.  We thank the Military Suicide Research Consortium for providing funding for this study.

Validating The Alliance Project Gatekeeper Training

The Alliance Project is a gatekeeper training that was developed as part of our 2013-2016 SAMHSA campus GLS suicide prevention grant.  As part of our new state-wide GLS grant we will be collecting validation data in order to strengthen the empirical basis of this empirically-derived gatekeeper training.  Additionally, we will use these data to continue to improve and refine our gatekeeper training.

Measuring nightmares: the Mississippi State Bad Dreams and Nightmares scale

Although there is evidence that nightmare frequency and severity are two related but separate constructs, as are bad dreams and nightmares, there are few nightmare measures that bring all of these constructs together in one measure.  We are in the process of writing up our validation of the Mississippi State Bad Dreams and Nightmares scale in the hopes of providing the field with a new measure that incorporates all of these important constructs.

Student projects

In addition to these we have several on-going student projects.  Ashley and Anisha are currently working on an acculturation project, Anisha is studying the impact of race and ethnicity on suicidal behavior, and Courtney is examining human-animal interactions, particularly in relation to depression in older adults.


Michael R. Nadorff, Ph.D., Director

Dr. Michael Nadorff (far right pictured above) received his bachelor’s degree from the University of Notre Dame in 2007 with degrees in Psychology and Computer Applications.  He received his master’s and Ph.D. in Clinical Psychology at West Virginia University and completed his clinical residency at Baylor College of Medicine.  Dr. Nadorff’s research interests involve the relations between sleep disorders, suicidal behavior, and aging. A particular focus of Dr. Nadorff’s work has been examining the relation between insomnia symptoms, nightmares, and suicidal behavior.  Dr. Nadorff is also interested in changes in suicidal behavior with age and investigating the efficacy and effectiveness of sleep treatments such as Cogntive Behavioral Therapy for Insomnia and Imagery Rehearsal Therapy for nightmares.  In 2021 he was named a fellow of the Society of Behavioral Sleep Medicine.  Dr. Nadorff has been continuously funded since 2013, receiving funding from SAMHSA, NIMH, CDC, and the Mississippi Department of Mental Health.

Dr. Nadorff IS NOT planning to accept a clinical doctoral student for Fall 2024 (updated 9/9/23)

Intellectually-curious, hardworking graduate students are invited to apply to the sleep, suicide, and aging lab.  Students who have an interest in suicidology, behavioral sleep medicine, or clinical gerontology will likely be the best fit for our laboratory.  The lab can be best described as research intensive, though given the lab’s focus on applied research (particularly behavioral sleep medicine and suicide prevention), clinically-minded students may also find the lab to be a strong fit as long as they are willing to be active researchers while in the lab.

Graduate students are treated as junior colleagues within the lab, and are expected to play an active role in the lab.  In addition to their milestone projects (e.g. thesis), graduate students are expected to play a significant role in at least one of the lab projects, as well as help mentor the undergraduate students.  Graduate students may also have the opportunity to collaborate with other labs so long as they are making good progress on their milestone projects and meeting expectations.

Although not required by the clinical psychology PhD program, our students pick an external member for their dissertation committees.  Inspired by the European dissertation model, this committee member is typically a premier researcher in the topic being studied.  To date, we have been fortunate to have Drs. Julie Cerel, Anne Germain, and Christy Hoffman serve as external committee members.

Prospective students who are seriously considering our lab are encouraged to learn more about our graduate programs and then email Dr. Nadorff so he is aware of your interest and can watch for your application.  After emailing Dr. Nadorff, please apply!

Prospective Undergraduate Students

The Sleep, Suicide, and Aging laboratory occasionally has openings for undergraduate research assistants to help us with our various studies.  In addition to learning about the lab’s research and gaining research experience, research assistants may assist with participant recruitment, entering data, and administrative tasks such as making copies and calling participants.  Advanced research assistants may also have the opportunity to play a more hands-on role with our research projects, including potentially having the opportunity to present at research meetings, or taking part in publications.  If you are interested in joining, please complete our lab application Download here.
