Department Chair

15 Michigan Street NE, Grand Rapids, MI 49503
(616) 234-2732 

Dr. Brown is the founding chair of the Department of Emergency Medicine at the Michigan State University College of Human Medicine. After graduating from medical school in 1986, he completed his EM residency training at Butterworth Hospital where he subsequently joined the faculty. It was during this period when he developed a passion for summarizing evidence in a form that is useful to clinicians. This interest led to a MSc degree in Epidemiology with a focus on evidence synthesis (i.e., meta-analysis). Dr. Brown serves as the University Physician, on the Editorial Board for Cochrane, and as the Editor for Cochrane Evidence Synthesis and Methods.

Joshua Reynolds, MD, MSJoshua Reynolds, MD, MS
Associate Professor

Joshua C. Reynolds, MD, MS, joined the faculty at Michigan State University College of Human Medicine in 2013 as an assistant professor of Emergency Medicine. Dr. Reynolds is a graduate of the University of Pittsburgh School of Medicine. He completed his Emergency Medicine residency at the University of Maryland then returned to the University of Pittsburgh to complete a two-year research fellowship through the University of Pittsburgh Institute for Clinical Research Education. His primary research interests are cardiac arrest and post-resuscitation care.

Dr. Reynolds has authored or co-authored numerous peer-reviewed publication and book chapters. His early career projects received several Young Investigator Awards at the American Heart Association Resuscitation Science Symposium. Dr. Reynolds sits on the Advanced Life Support Task force of the International Liaison Committee on Resuscitation (ILCOR) and the Editorial Board for Resuscitation. He is also the site lead investigator at Corewell Health for the NIH-funded Strategies to Innovate Emergency Care Clinical Trials Network (SIREN).

Dr. Reynolds is board certified in Emergency Medicine and practices at the Butterworth campus of Corewell Health in Grand Rapids, MI, where he holds an appointment as adjunct assistant physician scientist.

Michelle Padley headshot.Michelle Arisleida Padley, PhD, CRTM
Assistant Professor

Dr. Padley is a Western Michigan University graduate of the Interdisciplinary Health Sciences PhD program. She also earned a Master of Science in Clinical and Medical Bioinformatics, with a certification in Clinical Trial Management from Grand Valley State University. She joined the faculty of Emergency Medicine in 2024. She has nearly 20 years of extensive experience in clinical research, medical student mentorship, and data science methodology. Her primary areas of inquiry include addressing out-of-hospital healthcare disparities, early medical student education, mixed-methods research, and novel data visualization.

The Emergency Medicine Department has a strong clinical research program which has been in place for over 25 years with a goal to improve emergency care by creating an environment of inquiry and scholarship. Teaching faculty and students are encouraged to participate in the development of new research projects, learn to critique biomedical research articles and develop habits of inquiry as a continuing professional responsibility.

The EM research team has initiated collaborative studies with other departments, area hospitals, universities, colleges, and community health agencies. In recent years, we have completed projects with the Kent County EMS; area nursing homes and adult foster care facilities; Medical Social Work and Respiratory Care Departments at Spectrum Health-Downtown Campus; the YWCA Sexual Assault Program; Grand Valley State University; Calvin College Department of Sociology; Akron General Medical Center in Ohio; Kent County medical Examiner, and Helen DeVos Children’s Hospital. The research team has also completed studies in collaboration with other residency training programs in Grand Rapids including radiology, surgery/trauma, internal medicine, forensic pathology and pediatrics.

Jeffrey Jones, MD, is associate chair for emergency medicine research. 

Resuscitation EM Research

The resuscitation of acutely ill or injured patients sits at the core of Emergency Medicine. As such, testing new ideas and questioning existing paradigms is paramount to advancing our specialty. 

Dr. Reynolds’ primary efforts within resuscitation science relate to cardiac arrest and post-resuscitation care, but he interested in any and all matters broadly related to resuscitation. To this end, the Department of Emergency Medicine has collaborated with multiple local entities including the Grand Rapids Fire Department, Kent County EMS, Frederick Meijer Heart & Vascular Institute, and the Cook Institute simulation center.

Dr. Reynolds is a member of the Advanced Life Support Task Force of the International Liaison Committee on Resuscitation (ILCOR). ILCOR task forces, comprising an international cross-section of clinicians and investigators, periodically review and appraise resuscitation science to generate written consensus on science and treatment recommendations for PICOST-style questions. These documents are disseminated to the American Heart Association and its global counterparts to be adapted into the guideline statements produced by these organizations.

Dr. Reynolds is also the site Principal Investigator at Spectrum Health for the Strategies to Innovate Emergency Care Clinical Trials Network (SIREN). SIREN is an NIH-funded clinical trials network dedicated to testing the efficacy of early treatments for patients with neurological, cardiac, respiratory, and hematologic emergencies. These trials are typically multi-disciplinary in nature, underscoring the intersection of Emergency Medicine with other acute care specialties.

Finally, Dr. Reynolds periodically supervises CHM students or Spectrum Health/MSU emergency medicine residents as they complete projects related to resuscitation science. These include start-up procedures to participate in the National Emergency Airway Registry (NEAR), using geographic information systems to geolocate instances of bystander CPR within Kent County, and a number of systematic reviews with meta-analyses.

Neurological EM Research

Despite the massive proliferation of published medical research and broad based efforts toward improving its interpretation through evidence-based medicine, significant gaps persist between what we know from research evidence and what we do in clinical practice. This problem is pervasive in medicine, but is especially critical in highly time-dependent conditions where any delay in initiating appropriate intervention negatively impacts patient outcomes.

Dr. Oostema's research interests include the assimilation of evidence-based practice into clinical care, particularly with respect to the evaluation and treatment of neurological emergencies. Recently, his research has been focused on prehospital stroke care. As the first link in the stroke chain of recovery, early identification of patients with stroke by EMS can significantly impact the speed and efficacy of downstream acute stroke care, yet EMS stroke recognition is inconsistent and often not systematically monitored. Dr. Oostema is currently the principal investigator of an American Heart Association Mentored Clinical and Population Research Award supporting the development and assessment of a regional system to monitor and improve prehospital stroke recognition, transportation efficiency, and activation of in-hospital stroke systems. Dr. Oostema's other interests include the Emergency Department evaluation and management of transient ischemic attack (TIA) and acute ischemic stroke.
