This is a cardiac, ultrasound-focused research position to be funded by an NIH/NHLBI grant supporting researchers in the Department of Radiology of Weill Cornell Medicine (WCM) in New York City. The successful candidate will work closely with internationally recognized investigators at WCM, New York University, and North Carolina State University. This project will develop new high-frequency ultrasound, plane-wave CMUT row-column instrumentation and signal-processing techniques to determine subtle changes in complex blood flow patterns in a mouse model of heart failure. Progressive changes to flow characteristics in a transverse aortic banding mouse model will be analyzed as a possible method of early detection prior to the development of left ventricle dilatation and heart failure
Daily responsibilities of the candidate include:
• Create test protocols for collecting high-speed ultrasound data using high-speed plane-wave techniques.
• Manage and organize data acquired by partner institution.
• Develop custom code for analyzing ultrasound data in your choice of software (MATLAB/Python/R/etc.). The analyses include flow characterization in small animals and phantoms, segmentation of cardiac structure, and strain imaging of myocardium.
• Assemble and organize a database of in vivo cardiac data and oversee analysis of the data as it relates to the clinical goals of the research program.
• Establish test protocols with clinical ultrasound machine, train clinical collaborators on feature and protocols use and manage data collection and transfer.
• Become familiar with cardiac function and cardiac diseases such as diseases related to left ventricle disfunction.
• Prepare visualizations of blood flow in format that provide insight into normal and abnormal flow patterns.
• Communicate and coordinate with New York area research team as well as technical team at NC State U.
• Attend weekly meetings with the PIs and record participate in the progress of the project on multiple fronts.
• Earned a recent or soon to earn a doctorate in mechanical, electrical, biomedical engineering or related relevant field.
• Experience with ultrasound imaging systems and technology.
• Hands on experience programming and using Verasonics Vantage systems.
• Proficiency with signal and image processing methods as they relate to ultrasound data processing.
• Familiarity with Doppler processing methods, including methods to estimate magnitude and direction of flow.
• Able to undertake benchtop ultrasound experiments to acquire reference flow data to validate imaging methods.
• Productive publication record.
• Experience presenting results at international scientific conferences.
• Programming skills in MATLAB related to ultrasound data processing. Other Attributes
• US citizenship, current U.S. immigration visa, or US visa eligibility should job offer be extended.
• Exposure to modern statistical techniques including linear mixed model analysis, machine learning and other large data analytical techniques.
• Familiarity with small animal ultrasound imaging, particularly cardiac imaging.
• Experience developing ultrasound instrumentation, particularly as it related to plane wave methods.
• Programming experimental acquisition systems using LabVIEW or MATLAB.
• Fabrication of mechanical and electrical parts as relevant to developing experimental system.
• Ability to effectively collaborate and communicate with a multi-disciplinary research team.
• 1-2 year initial appointment with potential for additional years.
Interested candidates should submit a single pdf file containing the following:
