I build data science tools to address challenges in medicine and clinical care. Specifically, I apply signal processing, image processing and machine learning techniques, including deep convolutional and recurrent neural networks and natural language processing, to aid diagnosis, prognosis and treatment of patients with acute and chronic conditions. In addition, I conduct research on novel approaches to represent clinical data and combine supervised and unsupervised methods to improve model performance and reduce the labeling burden. Another active area of my research is design, implementation and utilization of novel wearable devices for non-invasive patient monitoring in hospital and at home. This includes integration of the information that is measured by wearables with the data available in the electronic health records, including medical codes, waveforms and images, among others. Another area of my research involves linear, non-linear and discrete optimization and queuing theory to build new solutions for healthcare logistic planning, including stochastic approximation methods to model complex systems such as dispatch policies for emergency systems with multi-server dispatches, variable server load, multiple priority levels, etc.

My research interest lies in applying data science for actionable transformation of human health from the bench to bedside. Current research focus areas include cutting edge single-cell sequencing informatics and genomics; precision medicine through integration of multi-omics data types; novel modeling and computational methods for biomarker research; public health genomics. I apply my biomedical informatics and analytical expertise to study diseases such as cancers, as well the impact of pregnancy/early life complications on later life diseases.

The Aguilar group is focused understanding transcriptional and epigenetic mechanisms of skeletal muscle stem cells in diverse contexts such as regeneration after injury and aging. We focus on this area because there are little to no therapies for skeletal muscle after injury or aging. We use various types of in-vivo and in-vitro models in combination with genomic assays and high-throughput sequencing to study these molecular mechanisms.

My methodological research focus on developing statistical methods for routinely collected healthcare databases such as electronic health records (EHR) and claims data. I aim to tackle the unique challenges that arise from the secondary use of real-world data for research purposes. Specifically, I develop novel causal inference methods and semiparametric efficiency theory that harness the full potential of EHR data to address comparative effectiveness and safety questions. I develop scalable and automated pipelines for curation and harmonization of EHR data across healthcare systems and coding systems.

Dr. Likosky is a Professor, Head of the Section of Health Services Research and Quality in the Department of Cardiac Surgery at Michigan Medicine and faculty member at the Center for Healthcare Outcomes and Policy. Dr. Likosky’s work currently focuses on leveraging: (i) mobile health technology to identify objective and scalable measures for mitigating post-surgical morbidities, and (ii) computer vision to identify objective and scalable measures of important intraoperative technical skills and non-technical practices.

I direct the Machine Learning for Learning Health Systems lab, whose work focuses on developing, validating, and evaluating the effectiveness of machine learning models within health systems. This includes projects such as a machine learning-supported patient educational platform (https://ask.musicurology.com) to support decision-making for patients with urological conditions. In additional to my predictive modeling research, I study patient-facing mobile apps and have published on this topic in Health Affairs, the Journal of General Internal Medicine, and the Clinical Journal of the American Society of Nephrology, among others. I have additional leadership roles that recognize my expertise in machine learning at a local and regional level. I chair the Michigan Medicine Clinical Intelligence Committee, which oversees implementation of predictive models across our health system, and I serve on the Michigan Economic Development Corporation’s Artificial Intelligence Advisory Board, where I contribute to the state of Michigan’s vision on artificial intelligence. I also teach a health data science and machine learning course to over 60 graduate students per year.

I use machine-learning techniques to implement decision support systems and tools that facilitate more personalized care for disease management and healthcare utilization to ultimately deliver efficient, effective, and equitable therapy for chronic diseases. To test and advance these general principles, I have built operational programs that are guiding—and improving—patient care in costly in low resource settings, including emerging countries.

I am a pulmonary and critical care physician who is passionate about improving critical care delivery by applying advanced methods for causal inference to observational data. My prior work has leveraged real-world data clinical and administrative data to study the epidemiology of critical illness, the organization of critical care, and health care financing.

My current work leverages real-world clinical data to understand whether and how care team fragmentation (transitions of physicians and other providers while a patient is still hospitalized) influences clinical outcomes like survival and recovery. Answering these questions correctly requires methods that are attentive to the complex causal structure underlying the relationship, depicted here. It features time-varying exposures (A), confounders (L), and mediators (M), all of which can influence clinical outcomes (Y). Arrows in the figure identify directional (i.e., causal) relationships between variables.
