Christopher Bauer started working with Dr. Woods as an undergraduate research assistant at the University of Wisconsin – Milwaukee (UWM) in 2004.  At that time, he primarily conducted research studies with families of clients with Tourette’s Disorder, examining the effects of tic suppression.  After graduating with a major in psychology from UWM, he earned his Masters in Clinical Psychology from North Dakota State University (NDSU) and returned to UWM to work for Dr. Woods as a lab coordinator and project manager for a multi-year, federally-funded research study comparing behavior therapy to supportive therapy for adults with Trichotillomania.  In addition, Chris worked on research projects that focused on improving the effectiveness and dissemination of behavior therapy for Tourette’s; for these project, Chris filled the various roles of coordinator, evaluator, or therapist based on the needs of the project.  Following this, Chris continued his work in Dr. Woods’ lab as a research assistant at Texas A&M University.  While there, his research expanded to include all body-focused repetitive behaviors in addition to research related to Tourette’s and Trichotillomania.  Currently, Chris works as a research associate at Marquette University, and his responsibilities include coordinating research studies, advising graduate students and providing therapy in Dr. Woods’ Tic Disorders Specialty Clinic.

Jennifer's CV

Jennifer Alexander graduated with a B.S.B.A. (double majors in Psychology and Accounting) from Washington University in St. Louis in December 2013. She began the doctoral program in Clinical Psychology at Texas A&M University (TAMU) in the fall of 2014, working under Dr. Doug Woods’ advisement. After earning her master’s degree at TAMU, she transferred to Marquette’s Clinical Psychology doctoral program so that she could continue working with Dr. Woods and experience a “real” winter.

Jennifer’s research interests include (1) maladaptive emotion/emotion regulation in obsessive-compulsive spectrum disorders (OCSDs), (2) the interrelationship between the experiences/characteristics of persons affected with OCSDs and those of their social support persons, (3) the impact of sociocultural and psychosocial factors on the experience of OCSDs, and (4) treatments for OCSDs. She is currently working on her dissertation, which is exploring emotion dysregulation in trichotillomania using fMRI. This project is being funded through the grant she was awarded via the Clinical and Translational Science Institute of Southeastern Wisconsin (CTSI) START TL1 Program. In addition to her dissertation project, Jennifer is also overseeing a project aimed at investigating social perception of persons with trichotillomania and a project aimed at investigating parental experiences of pediatric.

Jordan's CV

Jordan Stiede graduated summa cum laude from Ripon College in 2017 with a B.A. in Psychobiology and a minor in Spanish. He entered the doctoral program in Clinical Psychology at Marquette in the fall of 2017. At Ripon, he conducted a cross-cultural, psychobiology study with Dr. Kristine Kovack-Lesh examining the influences of culture on nutrition and body image in Morocco and the United States. Also, in the summer of 2016, he worked with Dr. Lisa Feigenson at Johns Hopkins University, where he assisted with research on math anxiety in children and adolescents. Jordan’s research interests include examining cultural differences in environmental consequences and presentation of tics and understanding behavioral interventions for children and adults with Tourette’s and other OCD-spectrum disorders. He is currently working on his master’s thesis, which will explore cultural differences in environmental reactions to tics. In addition, he is recruiting and assessing participants for a long-term follow-up study in order to see if gains made in behavioral treatment for tics last over time, and he is recruiting participants for a study that is examining the impact of social interactions on tic frequency.


Current Projects

Cultural Differences in the Environmental Consequences of Tics

Description: Under the direction of Dr. Douglas Woods, the Tic Disorders Clinic at Marquette University is looking for parents of children with tic disorders to complete a questionnaire examining the cultural impact of environmental reactions to tics. For the study, you would complete an anonymous online questionnaire relating to your reactions to your child’s tics, your child’s tic severity, your child’s impairment attributed to tics and other behaviors, your parenting style, your emotions, and your social identity. The questionnaire should take approximately 30 minutes to complete.

To be eligible for the study, you have to:

  • Be at least 18 years old
  • Be the parent or guardian of a child who meets the criteria for Tourette’s Disorder or Persistent (Chronic) Tic Disorder
  • Be living in the same household as your child
  • Be able to read and write English

Examining the Impact of Social Interactions on Tic Frequency

Description: The purpose of this study is to determine if talking about tics impacts the frequency of tics. The study consists of three 10 minute conditions. For one of the conditions, you will be asked to sit quietly without talking.  For another condition, you will be asked to talk with the researcher about anything you want that is not related to your tics.  For the last condition, you will be asked to talk only about your tics with the researcher.  At the end of the third condition, your participation is complete. You will be audio and video recorded during the study to ensure accuracy.

To be eligible for the study, you have to:

  • Meet criteria for Tourette’s Disorder or Persistent (Chronic) Tic Disorder
  • Age 8 – 65
  • Speak English as a primary language
  • Have no history of psychotic disorders

Amygdala-Prefrontal Cortex Connectivity in Adults with Trichotillomania:
A Pilot Study

What is the purpose of this study?

Researchers at Marquette University and the Medical College of Wisconsin are conducting this 2-part study in the hopes of gaining a better understanding of how adults with Trichotillomania (Hair Pulling Disorder) regulate their emotions.

What will I be asked to do as part of this study?

Part 1:

  • Part 1 will take place at Marquette University.
  • In Part 1 of the study, you will be asked to complete several interviews and questionnaires.

Part 2:

  • Part 2 will take place at the Pavilion at Froedtert Hospital.
  • In Part 2 of the study, you will be scanned with a Magnetic Resonance Imaging (MRI) scanner.

Will I be compensated by participating in this study?

Depending on how much of the study you complete, you may be paid up to $60 for participating.

Who can participate?

You may be able to participate if you are over the age of 18, speak fluent English, and have been diagnosed with Trichotillomania or may have never been diagnosed with any psychiatric disorders.

Who do I contact if I am interested in getting additional information about this study?

Please call (414) 288-5746 for more information. Upon calling, you will be asked to complete an approximately 20 minute phone interview. This phone interview will help us determine whether you will be able to participate in the study.

You may also email with any questions about the study.
