Welcome to the Palliative Care Research Program.
Palliative Care is a relatively new field in healthcare that attends to the needs of seriously ill patients and their caregivers. In addition to a growing cadre of clinicians who provide palliative care, there is a growing community of scientists who are helping to understand the experience of patients with serious illness and the impact of serious illness care upon caregivers, as well as improving the evidence base for palliative medicine. The University of Michigan is proud to house one of the few formal research programs in this field. Feel free to learn about us and the important research we do, and to contact us if you are interested in being a part of our community or helping to support our work!
About Us
Who We Are
The Palliative Care Research Program is a multidisciplinary group of clinician scientists from the University of Michigan committed to collaborating with one another to understand the experience of patients with serious illness and the impact of serious illness care upon caregivers, as well as improving the evidence base for palliative medicine. We “hail” from various departments across the UM Schools of Medicine, Nursing, and Pharmacy.
What We Do
We conduct qualitative, quantitative, and interventional research with patients, caregivers, and providers. Topics include: symptoms, caregiver burden, appropriate and safe use of medications, physician knowledge, and pain mechanisms.
Our History
Our interdisciplinary team has been at the forefront of palliative care research. We were established in 2014 by the Adult Palliative Care Executive Steering Committee headed by Drs. John Carethers and Phil Zazove as a way to foster cross-discipline collaboration and synergy around research relevant to patients with serious illness, their caregivers, and their clinicians.
Our Affiliations
We have strong ties to other research programs across the UM campus including:
Faculty and Trainees

Maria Silveira, MD, MA, MPH is a federally funded researcher and ethicist who was among the first palliative care clinicians to practice at the University of Michigan and Ann Arbor Veteran Affairs Medical Center (VAMC). She grew up in New York City, completed her undergraduate studies at Harvard University, and obtained her medical degree from SUNY Stony Brook. After residency training at Oregon Health and Sciences University in Internal Medicine, she served as a Robert Wood Johnson (RWJ) Clinical Scholar at the University of Washington where she earned her MPH. She has been at the University of Michigan and Ann Arbor VAMC since 2001.
Her research aims to improve the management of symptoms related to cancer. She is the recipient of funding from the Robert Wood Johnson Foundation and Veterans Administration. She is currently site-PI for a PCORI-funded randomized controlled trial of integrated palliative care via telehealth for patients with advanced lung cancer in partnership with researchers at Massachusetts General Hospital.
Her research has been published in JAGS, JAMA, and NEJM. She has held several editorial positions, including Associate Editor for the Journal of Pain and Symptom Management and UpToDate. In 2014, she was awarded fellow status by the AAHPM and was promoted to Associate Professor at the University of Michigan. She currently serves as the Director for Research for the UM’s Palliative Care Program. She teaches ethics, communication, and symptom management to students and trainees at the UM and VA, and mentors fellows, junior faculty, and doctoral candidates in research.
Areas of Interest
- Cancer pain and chronic pain
- Safe use of opioids in palliative care and oncology
- Caregiving

Victoria Powell, MD is a clinical researcher in the Division of Geriatric and Palliative Medicine and palliative care physician at the Ann Arbor VA Geriatrics Research, Education, and Clinical Center (GRECC). She is interested in understanding how the physical symptoms of serious illness, such as pain, dynamically interact with an individual’s coping mechanisms, support structure, and comorbidities. Specifically, she focuses on how feelings of loneliness and demoralization contribute to pain and combinations of symptoms (ie., “symptom clusters”) such as pain, fatigue, and depression. Her research also attempts to better understand risk factors and clinical characterization of patients with chronic pain who receive long-term opioid therapy with an aim of developing more effective treatments for this population. Additionally, she serves as the Hospice and Palliative Medicine Fellowship faculty lead for scholarly projects.
Areas of Interest
- Chronic Pain
- Long-term opioid use
- Loneliness
- Demoralization
- Existential distress
- Opioid-non responsive pain
- Opioid use disorder in serious illness

Lauren Gerlach, DO, MS is a Geriatric Psychiatrist and Assistant Professor in the Department of Psychiatry. Her research is focused on understanding trends and appropriate use of psychotropic medications among older adults including evaluating how psychotropic medications are utilized in end-of-life care. She has used national survey and administrative claims data to evaluate the growth of central nervous system (CNS)-active medication polypharmacy use among older adults and to understand how health systems respond to warnings (e.g., from the U.S. Food and Drug Administration) for psychotropic medications. Her work aims to inform safe and rationale psychotropic medication prescribing among older adults with mental health and cognitive disorders—including understanding how to best target appropriate treatment to patients that would benefit from treatment the most.
Areas of Interest
- Trends and appropriate use of psychotropic medications among older adults with mental health and cognitive disorders
- End-of-life care for patients with dementia
- Patient, provider, and health system factors that influence the care that older adults receive

Pasithorn Amy Suwanabol, MD, MS is an Assistant Professor of Surgery in the Division of Colorectal Surgery with a clinical practice at the Ann Arbor Veterans Affairs Healthcare System. Dr. Suwanabol received her MD from the University of Wisconsin School of Medicine and Public Health. She completed her General Surgery residency at the University of Wisconsin Hospital and Clinics and her fellowship in Colon and Rectal Surgery at the University of Massachusetts-Memorial Hospital Medical Center. Dr. Suwanabol joined the faculty at U-M in September 2015 and is a core faculty member at the U-M Center for Healthcare Outcomes and Policy. Dr. Suwanabol's research focuses on improving the referral and delivery of palliative care among surgical patients. She is currently funded by the National Institute on Aging (R03) to examine the long-term implications of surgery among older adults and by Agency for Healthcare Research and Quality (K08) to optimize end-of-life care among older adults at high risk of postsurgical death or poor outcomes. She is on the editorial board of Annals of Palliative Medicine and has published her work in Journal of Pain and Symptom Management and Journal of Palliative Medicine among others.
Areas of Interest
- Optimizing palliative and end-of-life care among surgical patients
- Patient-centered outcomes in colorectal cancer surgery
- Quality improvement in colon and rectal surgery

April Bigelow, PhD is an Adult Gerontology Nurse Practitioner who earned her BS, MS, and PhD from the University of Michigan in Ann Arbor. After working for a number of years in higher education and community practice, Dr. Bigelow returned to training and completed a fellowship in Hospice and Palliative Medicine in 2019 through Michigan Medicine. Her current clinical practice is through Packard Health, a federally qualified health center and Outpatient Palliative Care through University of Michigan Health. In her practice she provides vulnerable patients with outpatient palliative care, advance care planning, and complex symptom management as well as primary care. In addition, Dr. Bigelow teaches in the Health Behavior and Biological Sciences Graduate Nurse Practitioner Programs at the University of Michigan School of Nursing. Since 2013, she has led a global clinical immersion experience in rural Thailand. Dr. Bigelow’s research focus includes the integration of palliative care practices and concepts into primary care and chronic disease management. Her most recent study aims to identify the current palliative knowledge of primary care providers. These data will be used to develop educational modules to provide primary care providers with the tools to initiate palliative conversations and interventions closer to the time of diagnosis with severe and life-limiting illnesses, likely improving overall quality of life.
Areas of Interest
- Outpatient palliative care
- Palliative Care in the primary care site
- Palliative Care Education
- Care of chronic illness
