Etiometry Board of Directors


Evan-ButlerEvan Butler | Board Member, President and CEO

Evan Butler is an engineer and entrepreneur who co-founded Etiometry in 2010. Previously, he worked at Boston Children’s Hospital in the Pediatric Cardiac Bioengineering Laboratory designing, building, and testing novel surgical robots and tools. Evan was also a NASA GSRP Fellow with Dryden Flight Research Center, and created intelligent flight control systems.

He received his Bachelor’s degree in Physics and Aerospace Engineering, and his Masters degree in Dynamics and Control Engineering from Boston University. Evan has published conference papers, journal articles and a book chapter in the fields of medical predictive analytics, concentric tube robots and tools for minimally-invasive beating heart surgery, and intelligent flight control systems. Evan has received multiple awards, including the 2010 IEEE Transactions on Robotics Best Paper Award.



Dimitar-BaronovDimitar Baronov, PhD | Board Member

Dimitar Baronov is a co-founder of Etiometry and leads the company’s research and development organization. He received his Bachelor’s degree from Technical University in Sofia, Bulgaria and a Ph.D. in Aerospace Engineering from Boston University. Before co-founding Etiometry, Dimitar developed a theory for optimal human-machine interaction in achieving complex tasks.

This work informed the U.S. Air Force, and provides a basis for Etiometry’s innovative approach to integrating analytics into medical care. As CTO of Etiometry, Dimitar is the lead designer of the Etiometry Platform that quantifies clinical risks based on continuous streams of physiologic data. He has also served as the Principal Investigator for several National Institute of Health grants.



Jesse-LockJesse Lock, MD Ph.D. | Board Member

Dr. Jesse Lock is the Chief Medical Officer and a co-founder of Etiometry. He received a BA from Amherst College in 1997, an MD from Albany Medical College in 2002 and a Ph.D. in Biomedical Engineering from Boston University in 2010. His dissertation research focused on modeling intra-cardiac robots for minimally invasive pediatric surgeries, and he has since co-authored a book chapter on predictive medical analytics.

Jesse has won several academic awards, including the graduate student Golden Apple Teaching Award, the Boston University Graduate Engineering Entrepreneurial Design Competition award, and the 2010 IEEE Transactions on Robotics Best Paper Award. He is currently an adjunct staff member at Boston Children’s Hospital and maintains a pediatrics practice in nearby Lexington, Massachusetts.


Etiometry Advisory Board

Dr. Peter Laussen, MB.BS., FANZCA, FCICM | Scientific Advisor

Dr. Peter Laussen is the lead inventor of the T3 platform. He initiated this work in 2009 when he was at Boston Children’s Hospital as the Chief of the Division of Cardiac Critical Care and Professor of Anesthesia at Harvard University. Support for the development of T3 came from the DD Hansen Chair in Pediatric Anesthesia and the Departments of Cardiology and Anesthesia at BCH.  In 2012, Peter moved to Toronto as the Chief of the Department of Critical Care Medicine at the Hospital for Sick Children, Professor of Anaesthesia at the University of Toronto, and as the David and Stacey Cynamon Chair in Critical Care Medicine. He is a full time intensive care physician, specializing in children with heart disease, and is co-Chair of the Machine Learning for Healthier Kids steering committee. T3 was installed in the DCCM at Sickkids where Peter has continued to review, refine and extend the performance of the platform to meet clinician needs at the bedside and for their research purposes.

He graduated from Melbourne University Medical School, Victoria, Australia, in 1980, and completed fellowships in anesthesia and pediatric critical care medicine.  He has the good fortune of working on staff at 3 major pediatric hospitals across the world, Royal Children’s Hospital, Melbourne(1989-1992), Boston Children’s Hospital (1992-2012), and The Hospital for Sick Children, Toronto (2012 to present).  His professional interests focus on the use of continuous physiologic data for predictive modeling at Laussen Labs; a diverse team in Toronto conducting research in this area.  He has considerable experience in quality, systems and human engineering applied to critical care.  In 2006 he was a founding member of Risky Business, a unique forum for discussing risk management in healthcare.
