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), and the Military Suicide Research Consortium (MSRC).

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.

Differentiating between military members who have suicidal ideation and suicide attempts.

Kat Speed’s thesis project (under review) demonstrated that sleep disorders can differentiate between those who have previously attempted suicide and those who have not in the general population.  For Patricia Cartwright’s dissertation, we are following up on this research by examining the factors that differentiate military members who think of suicide and have a history of one or two suicide attempts using data from the Military Suicide Research Consortium Common Data Elements.

Cognitive Correlates of Suicidal Behavior

One potential explanation for suicidal behavior is that it is a failure of problem solving.  A person considers suicide when they encounter a problem where they can think of no better solution than suicide.  To delve into this deeper, Caitlin Titus is working closely with Dr. Andy Jarosz from our Cognitive Psychology program to look into whether problem solving deficits are associated with suicidal ideation, suicide risk, and past suicide attempts.


Lab Members and Alumni

Michael R. Nadorff, Ph.D., Director

Dr. Nadorff 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.

Patricia Cartwright, M.S.

Patricia is a native of Garland, TX and a fourth year in the Clinical Psychology PhD program. Currently, Patricia is an instructor of record and also a clinician at North Mississippi State Hospital. In her free time, Patricia enjoys spending time with friends and family, playing with her 2 dogs (Sarge and Koco), exercising, and traveling. Patricia’s dissertation is examining what factors differentiate individuals who think about suicide and attempt suicide in a military sample (external committee member: Dr. Pete Gutierrez). Her current research interests include mental illness stigma, nightmares, the assessment and treatment of adjustment disorders, posttraumatic stress disorder (PTSD), and suicidal behaviors in the military population.

Katrina (Kat) Speed, M.S.

Kat is a fourth year graduate student in the Clinical Psychology PhD program. She graduated from Mississippi University for Women with a Bachelor of Arts in Psychology and a Business Management minor. Prior to joining the MSU PhD program, she worked as a grant writer, Project Director, and volunteer supervisor for a local SAMHSA-funded Crisis Center Follow-up Grant. Her love for working in a crisis center setting led her to develop clinical and research interest in suicide prevention, trauma, and sleep disorders. Further, Kat is interested in working to promote better mental health outcomes for all military service members. For her dissertation, Kat is comparing the effectiveness of Imagery Rehearsal Therapy for Nightmares administered in-person to administered via a smartphone app in a sample of active duty military and Veterans (external committee member: Dr. Anne Germain).

Caitlin E. Titus, M.S.

Caitlin is a second year graduate student in the Clinical Psychology PhD program here at State. She received her master’s degree in Human Development with a concentration in Research from the University of Rochester where she then spent 3 years working on an adolescent suicide prevention program. Caitlin then moved to the Canandaigua VA Medical Center and continued research in suicide prevention with Veterans. Inspired by these experiences she decided to go back to school with the hope of one day running her own research in the field of suicide prevention. More specifically, Caitlin would like to examine both resiliency and risk factors within prevention programs and their connection with suicide attempts and deaths rates in populations.  Caitlin is doing a second thesis project which is examining cognitive predictors of suicidal ideation.

Lab Alumni

Christopher Drapeau, Ph.D.

Dr. Drapeau completed his post-doctoral fellowship in our lab.  He  is an Assistant Professor in the Department of Education, serving as a faculty member in the graduate M.Ed./Ed.S. School Psychology Program. He completed his doctoral training at Ball State University, where he specialized in school psychology, clinical neuropsychology, and counseling psychology. Christopher completed an APA-accredited doctoral internship in the Psychological Services Department at Cypress-Fairbanks ISD, where he also specialized in parent management training (PMT). During his postdoctoral fellowship at Mississippi State University, he specialized in behavioral sleep medicine and provided mid-level supervision to Clinical Psychology doctoral students providing PMT services.

Courtney (Shea) Golding, Ph.D.

Dr. Golding is one of the first four graduates from the Clinical Psychology PhD program at MSU, and is also the first graduate from our laboratory.  She received her master’s degree from MSU, with her thesis focusing on parenting and discipline practices (Dr. Cliff McKinney, chair).  Her dissertation, which was funded by the Military Suicide Research Consortium, focused on the role religiosity plays in coping after the suicide of a loved one (external member: Dr. Julie Cerel).  Dr. Golding practices Behavioral Sleep Medicine at Spectrum Health in Grand Rapids, Michigan.


Dr. Nadorff is planning to accept a clinical doctoral student for Fall 2018

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), 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 Pete Gutierrez 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.
