Innovating for a better future
Lumfonto LLC was formed in early 2017 to optimize and commercialize the endovascular flow simulator developed at the University of Minnesota.
Dr. Omid Amili along with his longtime friend and colleague, Dr. Ehsan Yakhshi-Tafti, formed this start-up to further develop the cardiac flow system and turn it into a high-performance and cost-effective product for in-vitro flow measurements.
The cardiac flow loop has already been used to replicate blood flow in a wide range of applications from replicas of small/large arteries to valves in veins.
Omidâs research area has focused on understanding physics of fluids and development of hardware and software for flow diagnostics. He holds a PhD degree in Mechanical Engineering from Monash University (Melbourne, Australia). His doctoral experimental work was focused on the study of wall-bounded turbulent flows using Particle Image Velocimetry (PIV) and wall shear stress measurements. As a primary objective, he developed a state of the art sensor capable of measuring wall shear stress applicable to turbulent flows. He also developed a sensor as a direct method for measuring wall shear stress in a relatively large field of view with high-spatial resolution in a non- intrusive way. Omidâs post-PhD research continued at Monash University between 2013 and 2015 with a focus on supersonic jets. The aim was to explore the physics of supersonic free and impinging jets using experimental techniques, including PIV, Holographic-PIV, and schlieren flow visualization. For this purpose, a state of the art jet facility was designed and built and a number of experimental studies were performed.
Omidâs research continued at the Aerospace Engineering & Mechanics, and Surgery department of the University of Minnesota, Minneapolis. Since 2015 he has been involved in biofluid related projects defined between the College of Science & Engineering, Medical School, and the Center for Magnetic Resonance Research (CMRR). This includes applying 4D-flow Magnetic Resonance Imaging (MRI) and PIV techniques for in-vitro flow diagnostics in patient-specific 3D-printed models of cerebral aneurysms; aorta grafted with a Left Ventricular Assist Device (LVAD); compliant cardiovascular stents; tissue-engineered bileaflet venous valves; and an array of compliant capillary tubes replicating small arteries. Instrumentation has also been developed in-house to generate physiological waveforms in an endovascular flow simulator, and a number of experimental conditions have been studied.
Ehsan Yakhshi-Tafti serves as Director of Research at Lumfonto. He received his doctoral degree in Mechanical Engineering from the University of Central Florida, where his research work was recognized as the Best Doctoral Dissertation of the College of Engineering in 2010. His research interests include fluid dynamics, heat and mass transfer and thermodynamics of small scale devices in the field of energy and biomedical sciences. He has expertise in MEMS Sensors & Actuators. He has led the development of novel technologies including passive micromixers and thermally-driven droplet manipulation platforms for lab-on- chip applications, and cooling systems for high heat flux electronics and lasers. Ehsan has authored 5 patents and published several articles in high impact scientific journals.
Omid is a lead Software developer at Lumfonto. Along with his computer skills, Omid brings expertise in application development and data analysis with IoT-scale data from connected field sensors.
Prior to joining Lumfonto, Omid was a research associate at Argonne National Laboratory, working alongside industry experts and other government laboratories to address vital national challenges in technology and chemical sciences. Before that, Omid conducted laser studies of small organometallic compounds at Rice Universityâs Department of Chemistry.
Omid holds a B.A. in Chemistry from Kalamazoo College.
