About Us

InHealth is how we practice precision medicine at Johns Hopkins Medicine. Precision medicine uses the latest technology to measure disease characteristics so we can identify patterns in groups of patients. We can then develop tailored treatment plans for individuals. We can also use this information to create proactive treatment plans, getting ahead of health problems before they occur.

How We Practice Precision Medicine

We’re researching the causes of disease through patient subgroups formed after measuring clinically important differences among patients who have the same disease. This data helps answer these questions:

People icon

How does the disease progress over time for similar patients?

Care icon

Do patients develop complications?

Treatment icon

Do they respond to specific therapies?


This information is placed on our inHealth computing platform, the Precision Medicine Analytics Platform (PMAP). Answers to questions such as these can be used to estimate and balance the likely benefits and risks of treatments given a patient’s preferences and tolerances.

Antony Rosen 

 “In addition to saving unnecessary expense treating people who will not respond, as part of Johns Hopkins inHealth, we are further studying what nonresponders will teach us about their disease so we can develop additional treatments that might work for more people.”

- Antony Rosen, Vice Dean for Research

    Opening Remarks

    Antony Rosen
    Antony Rosen, M.B.Ch.B., M.S., is the Mary Betty Stevens Professor of Medicine, and professor of pathology and cell biology. He is the director of the Division of Rheumatology and the vice dean for research at the Johns Hopkins University School of Medicine, as well as the director of inHealth, Johns Hopkins’ program in precision medicine and individualized health. Dr. Rosen received his medical degree from the University of Cape Town in South Africa in 1984. After completing his internship in medicine and surgery, he pursued postdoctoral studies in immunology at the Rockefeller University in New York (1987–1990). Drawn by a desire for a deeper understanding of human inflammatory diseases, he returned to clinical medicine and was an Osler resident and rheumatology fellow at The Johns Hopkins Hospital (1990–1994). He subsequently joined the faculty at Johns Hopkins in 1995, and rose to the rank of professor in 2002. He has been director of the Division of Rheumatology since then, overseeing a substantial expansion of the division. His research focuses on autoimmunity in the rheumatic diseases, using subgroups of patients with distinct phenotypes, trajectories and specific autoimmune responses to define molecular mechanisms.

    Panelists and Moderator

    Michael Miller
    Michael I. Miller is the Bessie Darling Massey Professor and Director of Biomedical Engineering at Johns Hopkins University. He is also co-director of the Kavli Neuroscience Discovery Institute.
    As a biomedical engineer who specializes in data science, Dr. Miller is pioneering cutting-edge technologies in computational medicine to understand and diagnose neurodegenerative diseases. His research focuses on the functional and structural characteristics of the human brain in health and disease, including Huntington’s disease, Alzheimer’s disease, dementia, bipolar disorder, schizophrenia, and epilepsy. By developing new tools to analyze patient brain scans, derived from advanced medical imaging technologies, Dr. Miller aims to predict the risk of developing neurological disorders years before the onset of clinical symptoms. His lab is currently devising cloud-based methods to build and share libraries of brain images—and the algorithms used to understand them—associated with neuropsychiatric illness. Dr. Miller’s research is highly translational, and he has co-founded four start-up companies in the past decade.

    Khyzer Aziz
    Dr. Khyzer Aziz’s research interests are utilizing complex information found in the electronic medical record and national registries/databases to provide clear, cohesive, and concise information for patients, families, and clinicians that can be used for clinical decision-making and neonatal precision medicine. With his mentorship team, he is developing and validating neonatal specific severity of illness metrics for the neonatal population – the neonatal sequential organ failure assessment (nSOFA) score and the vasoactive-inotropic score (VIS) – over the last year, he has published this work in high impact, peer reviewed journals. He is also the Director and Faculty/Scientific lead of the NICU Precision Medicine Center of Excellence (PMCOE) initiative at Johns Hopkins along with Dr. Frances Northington. His short-term goal is to develop and publish unbiased studies concerning major health outcomes for NICU patients using internal institutional databases and national data registries via neonatal specific severity of illness metrics (nSOFA and VIS). His hope is that these studies will provide the framework towards more effective pre- and postnatal counseling, quality improvement initiatives, and help build predictive models for individual disease processes. In doing this work, his ultimate goal is to build predictive models that can aid in producing the best outcomes for patients in the most cost-effective manner and build a path towards neonatal precision medicine.
