Researchers to advance distributed analytics to enhance fertility in families

A multidisciplinary team of researchers from Boston University and Harvard University is working to address women’s reproductive health challenges with the help of a $1.2M, four-year grant funded by the National Science Foundation (NSF) through its Smart and Connected Health (SCH) program. The BU-led project will leverage machine learning and artificial intelligence to develop an integrative approach to enable personalized reproductive/fertility predictions and individualized prescriptions to help address fertility problems. The researchers will also focus on improving the understanding of socioeconomic disparities in the use of infertility treatment services.

The demands of modern life, education and career choices, as well as the availability of assisted reproductive technologies, are leading many individuals and couples to delay childbearing. This has contributed to infertility and sub-fertility emerging as significant public health problems in the U.S., affecting about 15% of couples, and resulting in more than $5 billion spent annually in infertility services. Such costs are often not covered by health insurance and, consequently, generate access disparities.

“This project is an exciting illustration of the tremendous potential modern data science methods have to leverage the increasing availability of data and impact our health and wellbeing,” says Boston University College of Engineering Professor Ioannis (Yannis) Paschalidis, principal investigator (PI) of the project and director of the Center for Information and Systems Engineering. “With the emergence of personalized medicine, aided by data and algorithmic advances, we now have the ability to learn from available data and develop personalized predictions and intervention recommendations for each individual. The overall goal is to enable people to optimize health before conception, identify modifiable determinants of fertility, and reduce health risks during pregnancy and beyond.”

Innovative team of engineers and clinicians bring a synergistic range of expertise

The BU-Harvard University research team reflects the integrative nature of the project, bringing together algorithms, public health, and medical expertise to address clinical and socio-economic challenges contributing to infertility and women’s reproductive health.

The BU team of principal investigators include:  Yannis Paschalidis, BU Professor of Electrical and Computer Engineering, Systems Engineering, and Biomedical Engineering, an expert in decision theory, networks, machine learning, optimization, and computational biology/medicine; Alex Olshevsky, BU Professor of Electrical and Computer Engineering and Systems Engineering, an expert in distributed optimization methods; and Lauren Wise, ScD, BU Professor of Epidemiology, BU School of Public Health,  an expert in reproductive epidemiology and PI of the BU Pregnancy Study Online (PRESTO).

Harvard University is the subaward recipient on this grant, and brings the expertise of Co-PI Shruthi Mahalingaiah, Assistant Professor of Environmental Reproductive and Women’s Health. Professor Mahalingaiah is a reproductive endocrinologist, infertility physician scientist and PI of the Ovulation/Menstruation Health Study. Dr. Mahalingaiah holds an adjunct appointment at the BU School of Medicine in the Department of OB/GYN and directs the Program in Environment and Women’s Health, a multi-institutional collaborative effort which includes Boston Medical Center, BU School of Medicine, BU College of Engineering (Paschalidis), and Massachusetts General Hospital, and is housed at the Harvard T.H. Chan School of Public Health.

A shifting paradigm in health data collection

Electronic Health Record (EHR) data are distributed at many locations, hospitals, doctor offices, and other clinics.  Medical devices are also becoming smaller with the ability to transmit and store information at home monitoring stations, a patient’s smartphone, and the cloud.

“While traditional learning methods require collecting all data at a central location, this is becoming increasingly harder, even undesirable for privacy reasons,” says Co-PI Alex Olshevsky.  “Clearly, the more locations contain sensitive data, the greater is the likelihood of a data breach. In this context, it becomes important to develop fully distributed algorithms that can provide  privacy guarantees.”

The researchers will develop an integrative approach to enable personalized reproductive/fertility predictions and prescriptions using distributed, privacy-preserving algorithms trained using multiple data sources. The algorithms will combine information from self-administered surveys, electronic health records, and personal health records to produce highly accurate personalized predictions and prescriptions or recommendations, enabling individuals and their physicians to make the most appropriate, individualized health care decisions.

“Collaboration for improving discovery and improving care for women across the lifecourse is critically important,” says Dr. Mahalingaiah. “Merged datasets including self reporting, lifestyle, and exposures, clinical-grade data, and data collected from wearable devices will provide personalized insights so that women can be empowered to understand information on the health of their bodies and make the best choices for their health and futures.”

Predictive fertility/family planning models

The research team will develop fertility/family planning models, including predicting pregnancy, the success of an IVF cycle, the presence of specific reproductive health issues affecting fertility, and making related health care recommendations.  Predictive models will identify the most important factors associated with reduced fertility or Assisted Reproductive Technologies (ART) success rates, which could pinpoint specific lifestyle habits, environmental factors, and other key drivers of reduced positive outcomes that can inform health policy recommendations. A key focus will be on ovulation disorders, including Polycystic Ovary Syndrome, which are the leading cause of female infertility and are associated with an increased risk of chronic diseases, such as diabetes and cardiovascular disease.

“Machine learning has the potential to identify novel determinants of subfertility in large prospective cohort studies like PRESTO,” says Dr. Wise. “Developing tools for individuals to quantify their probability of conception based on personal inputs is paradigm-shifting. We are delighted to be partnering with Dr. Paschalidis and his colleagues on this innovative study.”

Professor Paschalidis adds, “It’s one thing to be able to predict one thing will happen, but the important question is, what do you do? How do you improve the condition of the individual?  By bringing together this truly multidisciplinary collaboration of clinicians and engineers, this project brings the deep, diverse expertise and requisite resources for advancing the health and wellbeing of women.”

Researchers Win $900k NSF Grant to Predict Heart Disease, Diabetes Using Machine Learning

August 22nd, 2019 in Awards, Research

By Maureen Stanton, CISE

Researchers (from left) Paschalidis, Mishuris, and Cassandras win $900K NSF grant to predict heart disease and diabetes using machine learning.


Researchers from the Boston University College of Engineering and Boston Medical Center (BMC) will use a three-year, $900,000 grant from the National Science Foundation to develop and pilot a health informatics system to predict patients at risk of heart disease or diabetes, and enable early intervention and personalized treatment.

“Our research vision is to deliver personalized healthcare, from prediction to diagnostics to population health management,” said Professor Ioannis Paschalidis (ECE, BME, SE), director of the Center for Information & Systems Engineering (CISE).  “In earlier work, we demonstrated how machine learning could predict hospitalizations due to these two chronic diseases about a year in advance with an accuracy rate of as much as 82 percent, a significant improvement over existing risk models — such as the Framingham study for cardiovascular disease.  Now, with our synergistic team of scientists and physicians, we are developing more robust predictive methods and capabilities for offering personalized recommendations that can guide physicians and patients as they make health-related decisions. This is a new frontier in medical informatics research and we expect it will impact medical practice.”

Diagnosing these chronic diseases requires complex sets of clinical and pathological data, which often are not comprehensive, consistent, nor up to date for treating physicians.  The result is that patients at higher risk often don’t get needed treatment, while those at lower risk do, leading to poor patient outcomes and unnecessary costs. The new, interdisciplinary research collaboration will be led by Paschalidis, CISE member Professor Christos Cassandras (ECE, SE) and BMC Associate Chief Medical Information Officer and BU School of Medicine Assistant Professor of Medicine Rebecca Mishuris. They will develop a new generation of predictive methods based on supervised machine learning techniques that are interpretable, have higher predictive power, and can handle more data.

The researchers will develop an approach based on novel mathematical methods and the requisite algorithms where electronic health records and real-time health data — including wearable, implantable, and home-based, networked diagnostic devices – can be used to develop prediction analytics that anticipate future events such as hospitalizations, re-admissions, and transitioning to an acute stage of a disease. These predictions trigger personalized interventions, ranging from increased monitoring and doctor visits to optimized treatment policies adapted to each patient.

The researchers will also focus on enabling personalized treatment based on learning and optimizing treatment protocols for chronic diseases. “Protocols of this type are typically empirical, using a one-size-fits-all approach,” explained Cassandras, head of the Systems Engineering Division. “They assess the stage of the disease and adapt medication based on the stage but not the patient. By incorporating specific personalized interventions with recommendations, clinicians can, therefore, intervene before a patient’s condition reaches a critical phase.”

In addition to methodological and algorithmic development, the project will pilot the newly developed algorithms by integrating them into the electronic health record system at BMC and with 14 affiliated Community Health Centers.

“Personalized, predictive healthcare is the future of medicine,” said Dr. Mishuris.  “Our research is geared toward providing clinicians with powerful, interpretable data to achieve that goal.  Physicians are drowning in data and administrative processes.  Our research approach will help physicians manage the deluge of clinical and patient data to make decisions in a more systematic fashion.”

Wuyang Dai receives the College of Engineering 2015 Societal Impact Dissertation Award

June 12th, 2015 in Awards

Wuyang Dai, a 2015 graduate of NOC, received the College of Engineering 2015 Societal Impact Dissertation Award for his thesis "Detection and Prediction Problems with Applications in Personalized Health Care."

The thesis developed algorithmic methods to support personalized preventive medicine. One of the problems addressed is the prediction of hospitalizations due to heart disease based on a patient's Electronic Medical Record. Analyzing records of more than 45,000 Boston Medical Center patients, the new algorithms predict about 80% of hospitalizations with few false positives. Prediction enables prevention which can improve outcomes and reduce the more than $9B spent annually in the US on preventable heart-related hospitalizations.

Dean’s Catalyst Awards Energize Early-Stage Projects

June 1st, 2011 in Awards

By Mark Dwortzan

Assistant Professor Ajay Joshi (ECE) is one of seven College of Engineering faculty members to receive a 2011 Dean's Catalyst Award.

Assistant Professor Ajay Joshi (ECE) is one of seven College of Engineering faculty members to receive a 2011 Dean's Catalyst Award.

College of Engineering research projects in nanofluidics, integrated circuit design, data-driven healthcare management and Terahertz radiation generation are set to take off, thanks to the Dean’s Catalyst Awards (DCA) grant program. This year four research teams will each receive up to $50,000 in DCA funding to develop novel techniques to investigate these topics.

Established by Dean Kenneth R. Lutchen in 2007 and organized by a faculty committee, the annual Dean’s Catalyst Awards program encourages early-stage, innovative, interdisciplinary projects that could spark new advances in a variety of engineering fields. By providing each project with seed funding, the awards give full-time faculty the opportunity to generate initial proof-of-concept results that could help secure external funding.

This year’s DCA-winning projects promise to improve the nation’s healthcare, defense, information and communications systems.

Leveraging their respective skills in computational modeling of nanomaterials and fabrication/testing of nano-electromechanical systems, Assistant Professor Harold Park and Associate Professor Kamil Ekinci (both ME, MSE) will study the ability of graphene, the world’s only known 2D material, to increase fluid flow through nanoscale channels. By utilizing the hydrophobic properties of the world’s thinnest known material (graphene is composed of a single layer of carbon atoms) to significantly enhance the fluid flow rate in confined, nanoscale channels, the researchers aim to improve the performance of nanofluidic devices and lab-on-a-chip technologies. Potential application areas include biological and chemical sensing, homeland security and healthcare.

Combining low-power circuit and micro-architecture design techniques with ideas from coding and information theory, ECE Assistant Professors Ajay Joshi and Bobak Nazer plan to develop a new approach to digital VLSI (very large scale integrated circuit) design that tolerates errors at the device level while maintaining global reliability at the architectural level. Rather than paying the ever-increasing energy and area costs required to keep all devices well-behaved, the researchers intend to allow individual transistors to be “noisy.” The goal is to develop an architecture that exploits feedback and redundancy to maintain nearly the same end-to-end reliability and performance as today's designs while consuming much less energy.

Professor Ioannis Paschalidis (ECE, SE), Daniel Newman, BUMC assistant professor of medicine and Boston Medical Center (BMC) chief medical information officer, and Shiby Thomas, BMC director of enterprise analytics, will pursue a comprehensive and systematic approach to intelligently processing Electronic Health Records (EHRs) and directing physician attention to preventing serious medical conditions. Using algorithms that assess patients for disease risk and trigger physician actions based on their risk classification, and wireless body sensors that dispatch medical information to the clinic in near real-time, the researchers’ proposed system could significantly reduce costs and improve efficiencies in the U.S. health care system.

Despite major application opportunities in medical and chemical imaging and security screening, there are few sources that emit electromagnetic radiation in the Terahertz (THz) range (0.3-10 trillion Hz). Combining their respective expertise in graphene fabrication and THz radiation studies, Professors Anna Swan and Roberto Paiella (both ECE, MSE) propose an entirely novel way of generating THz radiation that, unlike current state-of-the-art methods, is not limited by intrinsic material properties. They plan to develop a “tabletop cyclotron source” of THz light that exploits the excellent electron transport properties of graphene to produce radiation in the Terahertz range.

“The Dean’s Catalyst Award is an ideal platform for exploring novel ideas that are promising, but need more probing to understand their true potential,” said Joshi. “We are grateful for this opportunity to refine our ideas and develop preliminary results before applying for external funding.”
