<p><span><span>The Cardiac Biomechanics Laboratory at the University of California San Francisco Medical Center (UCSF) Division of Cardiothoracic Surgery and San Francisco VA Medical Center, is seeking a hard working, motivated post-doctoral fellow to participate in biomedical engineering research involving the development of transcatheter aortic valves which treats aortic stenosis with a percutaneous therapy. Our lab has a submitted patent on a transcatheter aortic valve design and developed a start-up company ReValve Med, Inc. The project involves transcatheter aortic valve replacement (TAVR) prototypes, hemodynamic testing via experimental fluid mechanics studies using a pulse duplicator and accelerated wear tester, particle image velocimetry, as well as optimization of design using fluid-structure interaction simulations. Experience in experimental fluid dynamics and computational simulations will be highly regarded. Also, experience in biomechanics and biaxial stretch testing to optimize leaflet material for the designed product would be ideal. Previous experience in prototype development would also be ideal. The individual would enhance their research experience in a multidisciplinary approach, gain exposure to an academic research environment, as well as participate in research for a start-up company. Highly successful candidates may have potential for stock options at the discretion of the CEO. The position is ideal for those who are dedicated to becoming academic professors or transition into engineers in industry. There is potential opportunity to observe cardiac surgery and learn about the treatment of cardiovascular disease.</span></span></p>
<p><span><span>The Cardiac Biomechanics Laboratory has had a focus on finite element modeling of transcatheter aortic valves, as well as Ross operation, and ascending thoracic aortic aneurysms.<span> </span>Proof of concept of our new transcatheter heart valve and delivery system is our goal for the next two years. The goals computationally are to perform finite element/fluid structure interaction modeling of transcatheter valves to assess stent and leaflet stresses, and to better understand patient-specific implantation. Experimentally, the goals are to development of prototypes for hemodynamic assessment in the lab’s pulse duplicator and accelerated wear tester as well as perform particle image velocimetry to compare our valve with current commercial valves. Additional biomechanical assessment of aneurysm tissue obtained from the operating root for root material properties will be required.</span></span></p>
<p><span><span>Other duties include presentations nationally, writing of experimental protocols, data analysis and publication, as well as obtaining grants. Salary and benefits are within the standard range as determined by NIH, institutional guidelines, and applicant experience. Individuals must have prior research experience and preference will be given to those with established experimental fluids experience as well as advanced computational simulations. Those with computer science knowledge involving C++, MatLab, RapidForm, LS-DYNA, ABACUS are preferred. Interested individuals should send via email to </span><a href="mailto:elaineetseng+postdoc@gmail.com"><span><span>elaineetseng+postdoc@gmail.com</span></span></a><span> : 1)cover letter with short and long term professional goals, 2)copy of undergraduate and graduate transcripts (unofficial copy in MS word format is acceptable), 3)three letters of reference with contact information (email acceptable) and 4)detailed resume.</span></span></p>

The post-doctoral fellow should be motivated to be on a career track to become an academic professor. Our lab is NIH funded to investigate the biomechanics of aortic aneurysms and currently has 1 postdoctoral fellow, and are seeking 2 additional fellows. The goals are to determine aneurysm aortic wall stress in relationship to aneurysm failure strength. Finite element models will be developed by using in vivo magnetic resonance imaging (MRI) and specimen micro-computed tomography (Micro-CT) for FEA. Specimens will undergo biaxial stretch testing to failure. 4D flow MRI will provide flow input conditions and enable fluid-structure interaction simulations to evaluate wall shear stress contribution. The second position will focus on biomechanics and fluid dynamics of transcatheter aortic valves (TAVs) which treat aortic stenosis with a percutaneous therapy. Computational simulations as well as experimental pulse duplicator and particle image velocimetry work will be performed on current TAVs and those in design/prototype stage. Our lab has a submitted patent on a new transcatheter aortic valve and we will be working on device prototyping and development. A strong background in computational experience is required. Furthermore, experience in experimental biomechanics using biaxial stretch testing and fluid dynamics using a pulse duplicator and accelerated wear tester is ideal. The individual would enhace their research experience in a multidisciplinary approach and gain exposure to an academic surgical environment with expected progression to independence as faculty in academics. There is potential opportunity to observe cardiac surgery and learn about the treatment of cardiovascular disease.</p>
<p>The Cardiac biomechanics laboratory has several broad areas of focus, including finite element modeling of the aortic root for transcatheter aortic valves, for the Ross operation, and for ascending thoracic aortic aneurysms. Proof of concept funding has previously been obtained to optimize the transcatheter aortic valve patent leaflet and stent design and study its biomechanics and fluid-structure interactions. R01 funding has been obtained to study ascending thoracic aortic aneurysms, using biomechanics to predict clinical failures and timing of surgical intervention.</p>
<p><span><span>Individuals must have prior research experience and preference will be given to those with expertise in advanced mathematical modeling skills, including developing their own code, C++, MatLab, RapidForm, LS-DYNA, ABAQUS.

The Cardiac Biomechanics Laboratory at University of California San Francisco Medical Center (UCSF) Division of Cardiothoracic Surgery and San Francisco VA medical Center is seeking a hard working motivated post-doctoral fellow to participate in biomechanical engineering research involving development of transcatheter aortic valves. Our lab has submitted a patent on a new transcatheter aortic valve (TAV) design and require design optimization by computational simulations in patient-specific scenarios. Experience in Biomechanics to optimize leaflet and stent material for the designed product would be ideal. The laboratory has a focus on finite element modeling of the aortic root for transcatheter aortic valves, Ross operation, and ascending aortic aneurysms. Proof of concept funding has been obtained to optimize the TAV patent leaflet and stent design and study its biomechanics and fluid-structure interactions. The goal is to determine material properties of candidate leaflet materials, optimize leaflet and stent design, perform computational simulations of patient-specific implantation and use FEM or FSI to assess leaflet and stent stresses. Biomechanical assessment of aortic aneurysm tissue obtained from the OR for root material properties will be required.
</p>
<p>
This position will involve computations simulations based on CAD design of TAV prototypes, microCT of actual TAVs, and patient CT images of the aortic stenosis. Experimental work will involve biaxial stretch testing for material properties, uniaxial failure testing and possibly prototype development and in vitro testing in a pulse duplicator or accelerated wear tester. Other duties include data analysis/publication, grant applications.
</p>
<p>
Salary and benefits are within standard rnage as determined by institutional guidelines and applicant experience. Individuals must have PhD and preference will be given to those with established computational skills and knowledge of C++, Matlab, Rapidform, LS-dyna, abacus is preferred. Interested individuals should send via email: cover letter with short and long term professional goals, copy of undergraduate and graduate transcripts (unofficial copy in MS word acceptable), letters of reference with contact information (email/phone) and detailed resume.
