Stephan Taylor

Stephan (Steve) Taylor, M.D.

Stephan F. Taylor, M.D., is Professor of Psychiatry and adjunct Professor of Psychology at the University of Michigan. He also serves as co-associate for Research and Research Regulatory Affairs in the Department of Psychiatry. He directs the Program for Risk Evaluation and Prevention. His research uses brain imaging, brain stimulation and behavioral techniques to study psychosis, particularly early psychosis, and to develop and improve treatments for psychiatric disorders.

Research Staff

Research Manager

Laura Stchur

Laura Stchur, M.S.W.

Laura Stchur is a licensed master social worker (LMSW) and began her clinical research career in 1998 while working at Wayne State University’s Neuropsychiatric Research Unit. In 2011, she was hired at the University of Michigan as the Clinical Research Program Manager for Dr. Taylor’s early psychosis clinic (PREP). Laura has managed numerous NIH and industry sponsored clinical trials focusing on psychosis, mood disorders, and obsessive compulsive disorder. She has clinical expertise in the diagnostic evaluation of psychiatric disorders in both adult and pediatric patients.

Research Coordinators

Pan Gu

Pan Gu, B.A.

Pan Gu is the research coordinator for Dr. Stephan Taylor and Dr. Ivy Tso. She recently completed her BA in neuroscience at Colorado College and joined the University of Michigan Department of Psychiatry in September 2019. She helps facilitate multiple research using neuroimaging and brain stimulation methods to investigate social cognition. Pan's research interest is in understanding the underlying neural mechanism behind serious mental illness. In particular, to examine social cognition between populations with and without a history of psychosis using behavioral and neuroimaging methods. In the future, Pan plans to pursue a Ph.D. in Clinical Psychology with a focus on neuropsychology.

Clara Steeby

Clara Steeby, B.S.

Clara Steeby is a research coordinator for Dr. Stephan Taylor. Clara recently graduated from the University of Michigan with a BS in neuroscience in May 2020. She joined the PREP research team in August 2020. Clara helps to coordinate GABAmech, a study investigating GABA levels and negative affect in patients with psychosis. Clara's research interests include the cognitive and neural mechanisms underlying mental health disorders, in particular studied via neuroimaging techniques. In the future, she plans to pursue a Ph.D. in Clinical Psychology.

Paula Brayboy

Paula Brayboy, B.A.

Paula Brayboy is a clinical research coordinator for Dr. Stephan Taylor. Paula joined the Department of Psychiatry at the University of Michigan in September 2019 to manage an NIH funded clinical trial that uses functional Magnetic Resonance Imaging (fMRI), medication, and neurocognitive testing to examine brain functioning in people with early psychosis, schizophrenia, bipolar depression, and healthy adults. Since completing her B.A. in Psychology at the University of Texas at Austin in May 2018, Paula has worked on two large clinical trials investigating effective treatments for anxiety and depression. Her current research interests are focused on using neuroimaging (i.e., fMRI) to better understand psychiatric disorders with the aim to develop and improve treatments for psychosis. Paula plans to pursue a doctoral degree in clinical psychology with an emphasis in neuropsychology.

Carly Lasagna

Carly Lasagna, B.A.

Carly Lasagna is a clinical science PhD student working with Dr. Ivy Tso. She is interested in the mechanisms of cognitive control and perceptual decision-making in psychosis and bipolar disorder. Her goal in research is to bring together computational modeling, neuroimaging, and neuromodulation methods in order to generate model-based neuroscience perspectives on complex psychiatric disorders that will facilitate more effective, individualized treatment. In her free time, she enjoys hiking, drawing, and photography.

Data Manager & Analysts

Tristan Greathouse

Tristan Greathouse, B.S.

Tristan Greathouse is a Data Analyst in the lab. Tristan's research interests involve applying novel statistical methods and machine learning algorithms to further advance neuroimaging analysis in the field of psychiatry. Outside of research, Tristan loves to run, climb, and explore any new adventure available to him.

Roen Montalva

Roen Montalva, M.S.

Roen Montalva received her MS in Clinical Health Psychology from Ohio University. She joined the Department of Psychiatry at University of Michigan in 2015 and currently is a data manager for Dr. Steve Taylor and Dr. Ivy Tso on the EPINET learning healthcare systems project. Previous experience encompasses organization, coordination, and analysis of measurement based care initiative as well as involvement in numerous health psychology research studies. Her research interest includes data driven decision making in mental healthcare and equity issues.

Peter Walczyk

Peter Walczyk, B.S.

Peter Walczyk is a Data Analyst in both the MiSCAN Lab and the Sripada Lab. He received his B.S.E in Biomedical Engineering at the University of Connecticut and his M.S in Biomedical Engineering at the University of Michigan. In the future, Peter would like to pursue a Ph.D. in Biomedical Engineering to further develop understandings of the underlying mechanisms of consciousness and create models of consciousness. In his free time, he enjoys art, cooking, and playing Dungeons and Dragons with friends.
