Associate Professor Of Medical Physics And Director Of Clinical Informatics, Department of Radiation Oncology and Molecular Radiation Sciences
Learning health systems in radiation oncology, Radiation dosimetry and treatment planning, Image guidance and adaptive radiotherapy
Dr. McNutt PhD is an Associate Professor and Director of Clinical Informatics in the Department of Radiation Oncology and Molecular Radiation Sciences. He has joint appointments in the Departments of Health Science Informatics and Computer Science in the Malone Center of Healthcare Engineering. Dr. McNutt’s primary research goal is to develop a learning health system in the context of radiation oncology for decision support and personalized radiotherapy.
Dr. McNutt has pioneered the development of a local level learning health system in radiation oncology with the Oncospace program for the last ten years. The system has been used to personalize radiation therapy by 1) predicting patient specific treatment plan quality (achievable radiation dose) and automating planning using the relationships between normal anatomy and tumor volumes based on the knowledgebase of prior patients; 2) predicting patients at risk of developing high grade treatment toxicities (e.g. xerostomia or dysphagia) or significant weight loss to guide care management; 3) predicting disease outcomes to guide intent and aggressiveness of treatment.
A primary component is creating a medical environment that allows us to measure how well we perform clinically for our patients. This requires incorporating medical IT infrastructure into the clinical setting and using it to measure the patient experience through clinician assessments, patient reported quality of life instruments and direct measures of patient condition and quantify it for analysis, trending and feedback. This has involved establishing workflows and human computer interfaces that enable the clinician to interact with the patients with minimal distraction while capturing the data. The effort has resulted in perpetual prospectively collected knowledgebases for head and neck, prostate, pancreas, and thoracic cancers that allow efficient analysis of clinical data to look at toxicity and outcome trends and how they correlate with the full 3D delivered radiation dosimetry within normal anatomy and targeted tumors.
Dr. McNutt also maintains research efforts in tradition medical physics applications to radiotherapy. He has worked to accelerate the treatment planning process developing a GPU based convolution/superposition dose computation algorithm for external beam radiation therapy that has been included in commercial systems for small animal radiation therapy planning as well as in quality assurance for treatment delivery in clinical systems.
Prior to his experience at Johns Hopkins, Dr. McNutt was the Director of Research and Advance Development for the Philips Radiation Oncology Systems developing the Pinnacle radiation therapy planning system. His work included intensity modulated radiotherapy planning and optimization, model based image segmentation and adaptive radiotherapy. This industrial work was done in a commercial software development environment following the FDA quality system regulations for medical device manufacturing and taught him best practices in software development and design to meet customer and user interface requirements.
Dr. McNutt maintains a strong interest in teaching post-doctoral fellows and students. Throughout his career he has mentored several post-docs and students in Medical Physics and Healthcare Informatics. He is also active teaching clinical residents in radiation oncology as well as students through lectures in Computer Science and Health Informatics.

Assistant Research Professor
I’m a medical doctor with surgical training and an epidemiologist. My research interests overlap several disciplines including clinical trials, different areas of surgery, epidemiology, biostatistics, and machine learning. I work on research related to measuring surgical skill and competency, technology for acquisition of motor and cognitive skill by surgeons, methods for fair comparisons of surgical interventions to estimate treatment effectiveness, analytics for surgical processes, and robotic assistance for skill acquisition and surgical coaching.
John C. Malone Assistant Professor, Electrical and Computer Engineering
Functional Neuroimaging (fMRI, EEG), Machine Learning & Probabilistic Inference, Network Modeling of the Brain, Integration of Imaging, Genetics and Behavioral Data
Archana Venkataraman’s research lies at the intersection of multimodal integration, network modeling and clinical neuroscience. Her main objective is to combine analytical tools, such as probabilistic inference and network theory, with neuroscientific findings in order to characterize complex processes within the brain. Her methodology has yielded novel insights into autism, schizophrenia and epilepsy, with the long-term goal of informing patient treatment and care. Archana received her Bachelors, Masters and PhD in Electrical Engineering from MIT in 2006, 2007 and 2012 respectively. She was a postdoctoral associate at both MIT and Yale prior to arriving at Johns Hopkins. Archana is affiliated with the Malone Center for Engineering in Healthcare at JHU, which aims to improve the quality and efficacy of clinical interventions.

Assistant Research Scientist
Human motor skill learning and motor control, Brain repair and rehabilitation
Jing Xu received her PhD (2011) in Psychology at University of California, Berkeley. Her PhD work was done in the laboratories of Cognition and Action, directed by Prof. Richard B. Ivry, and Computational Cognitive Science, directed by Prof. Thomas Griffiths. Her research was focused on human learning and control of movement, and human categorization.
She joined Johns Hopkins University in 2011, and worked with Dr. John W. Krakauer as a post-doctoral fellow. She was the lead post-doc of a longitudinal, multi-center project aimed at uncovering the biomarkers of stroke patients’ motor recovery, using multiple advanced neuroscience and clinical assessment methods. Her research has established that the human hand strength and dexterity recovery after stroke are mediated by separate biological systems.
Xu joined the Malone Center as an Assistant Research Scientist in 2017. Her primary research interest is to understand how people learn a motor skill. She uses research tools such as behavioral experiments, fMRI, TMS, and computation modeling questions to answer important questions about cognitive-motor representations, learning and control principles, recovery mechanisms after brain injuries, and strategies to enhance motor skills.
